Gulf of Mexico Oil Spill, PAHs, and Health

As part of SRP's focus on PAHs, we are sampling the polycyclic aromatic hydrocarbons (PAHs) in air and water in the Gulf of Mexico related to the oil spill. The level of PAHs in crude oil varies between 0.2 and 7%, depending on location. Although this seems like a small percent, PAHs are a significant toxicological health concern.

WHY ARE WE SAMPLING?

The use of complementary bio-analytical tools that quantify bioavailability processes is important to understand disasters such as oil spill risk.  The project goals will be to use air and water passive sampler devices (PSDs) in the Gulf of Mexico before, during and post impact from the Deepwater Horizon Spill of spring 2010.  

The PSDs are biological response indicator devices for gauging environmental stressors (BRIDGES) developed as part of a Superfund Program grant (Project 4). They bridge environmental exposure and biological response/effect. They can provide for rapid turnaround of data. 

View Training Videos of the passive sampling devices (English and Spanish)

The PSDs sequester PAHs, oxygenated PAHs (OPAHs) as well as other organic contaminants. OPAHs are potentially more mobile, bioavailable and/or persistent than PAHs.

There is growing evidence that OPAHs have important toxicological significance. The principle sources of OPAHs in aquatic systems are from photo-reactions and microbial degradation of PAHs.

Dispersants that increase bioavailability coupled with sites exposed to UV may increase OPAHs.

WHAT IS OUR EXPERTISE?

Dr. Kim Anderson, (Project Leader, Project 4; Core Leader, Analytical Chemistry Support Core D) has helped to firmly establish the PSD bio-analytical approach to assess spatial and temporal changes in the bioavailable fraction of contaminants at Gulf of Mexico contaminated sites.  Dr. Anderson is teaming with Dr. Robert Tanguay (Project Leader, Project 3; Co-I, Project 4), who has developed the zebrafish aquatic model to define the mechanism by which environmental bioavailable chemicals from air and waters affected by the Deepwater Horizon oil spill produce developmental toxicity.  

We are now poised to address important questions to bridge measurements of environmental levels and biological responses which would adversely impact human health.  This work is timely, innovative, and relevant in that we are addressing the gap between environmental exposure from oil spills and biological responses by use of a time integrated, bio-analytical system for selectively measuring the environmental exposure that elicits a toxic response.

Glossary for Oil Spill Research

Back to Main Page

Accute effects: Effects having a sudden onset and lasting a short time.

Ambient air monitoring: A systematic assessment of pollutant levels by measuring the quantity and types of certain pollutants in the surrounding, outdoor air. Note that most PAHs in ambient air are the result of man-made processes.

Ames test: A biological assay to assess the mutagenic potential of chemical compounds.

Analyte: A substance or chemical constituent that is determined in an analytical procedure.

Black Oil: A black or very dark brown layer of oil. depending on the quantity spilled oil tends to quickly spread out over the water surface to a thickness of about 1 millimeter. However, from the air, it is impossible to tell how thick a black oil layer is.

Bioaccumulation: The uptake and retention of a bioavailable chemical from any one of or all possible external sources (water, food, substrate, air).

Bioavalability: Chemicals that are able to penetrate permeable tissues of an organism.

Bio-assay: A measurement of the effects of a substance on living organisms

Biodegradation:  The chemical breakdown of materials by a physiological environment.

BRIDGES: Biological response indicator devices for gauging environmental stressors, Project 4 of the Superfund Program. More information.

Chronic effects: Chronic health effects are characterized by prolonged or repeated exposures over many days, months or years. Symptoms may not be immediately apparent.

Crude oil (crude oil petroleum): A fossil fuel formed from plant and animal remains many million of years ago. It comprises organic compounds built up from hydrogen and carbon atoms and is, accordingly, often referred to as hydrocarbons. Crude oil is occasionally found in springs or pools but is usually drilled from wells beneath the earth's surface.

Dispersants: Chemicals that are used to break down spilled oil into small droplets
Related link: Dispersants: A Guided Tour from NOAA
Related article: Ingredients of Controversial Dispersants Used on Gulf Spill Are Secrets No More (NY Times, 6-8-10)

Emulsions: A mixture of small droplets of oil and water.

Oil plumes: These are underwater globules of oil that do not float to the surface of the ocean. Scientists say microscopic oil droplets are forming these deep water oil bubbles. The heavy use of chemical dispersants, which breaks up surface oil, is said to have contributed to the formation of these plumes. Scientists are worried that these underwater globs will pose a threat to the marine ecosystem and that the oil could be absorbed by tiny animals and enter a food chain that builds to larger fish.

Oil Trajectory: NOAA uses a model to provide information about where a spill is likely to go.
Related link: NOAA Oil Spill Trajectory Maps 

OPAHs: Oxygenated PAHs (oxy-PAHs)

Passive Sampling Device (PSD):  A method of determining airborne and water concentrations of volatile contaminants. PSDs collect samples with a small badge-like device that relies on the diffusion of compounds to a collection surface or sorbent. The diffusion barrier across the badge confers a constant, predetermined effective flow rate that is only slightly affected by temperature and unaffected by pressure (or altitude). The PSD hangs in the sampling area for periods ranging from 8 hours to one month. After the sampling period, it is capped and returned to a laboratory for analysis using traditional methods.

Petroleum: Petroleum means "rock oil", from the Greek petros/Latin petra (rock), and the Greek elaion/Latin oleum (oil). The term petroleum is nowadays used as a common denotation for crude oil (mineral oil) and natural gas, i.e., the hydrocarbons from which various oil and gas products are made. Petroleum, then, is a collective term for hydrocarbons, whether solid, liquid or gaseous.

Polycyclic aromatic hydrocarbons (PAHs): See All About PAHs

Quality Assurance: The systematic monitoring and evaluation of the various aspects of the sampling project to ensure that standards of quality are being met.

Quality Control: Periodic checks to verify that data are generated, collected, handled, analyzed, and reported according to protocol.

Slick: A thin film of oil on the water’s surface.

Sorbents: Substances that take up and hold water or oil; sorbents used in oil spill cleanup are made of oleophilic materials.

Spreading: As soon as oil is spilled, it starts to spread out over the sea surface, initially as a single slick. The speed at which this takes place depends to a great extent upon the viscosity of the oil. Slicks quickly spread to cover extensive areas of the sea surface. Spreading is rarely uniform and large variations in the thickness of the oil are typical. After a few hours the slick will begin to break up and, because of winds, wave action and water turbulence, will then form narrow bands or windrows parallel to the wind direction. The rate at which the oil spreads is also determined by the prevailing conditions such as temperature, water currents, tidal streams and wind speeds. The more severe the conditions, the more rapid the spreading and breaking up of the oil.

Tar: A black or brown hydrocarbon material that ranges in consistency from a heavy liquid to a solid.

Tarball: Dense, black sticky spheres of hydrocarbons; formed from weathered oil.
Related flyer: NOAA on understanding tarballs (pdf)

Total Petrolium Hydrocarbons (TPH): A term used to describe a broad family of serveral hunderd chemical compounds that originally come from crude oil. TPH is really a mixture of chemicals. They are called hydrocarbons because almost all of them are made entirely from hydrogen and carbon. Crude oil can vary in how much of each chemical they contain. (ATSDR)

Toxicity: The degree to which a substance can harm humans or animals.

All About PAHs

What are PAHs?

Polycyclic aromatic hydrocarbons (PAHs) are a class of more than 100 chemicals composed of up to six benzene rings fused together such that any two adjacent benzene rings share two carbon bonds.

Where do PAHs come from?

The primary source of PAHs is from burning carbon-containing compounds. PAHs in air are produced by burning wood and fuel for homes. They are also contained in gasoline and diesel exhaust, soot, coke, and cigar and cigarette smoke. In addition, they are the byproducts of open fires, waste incinerators, coal gasification, and coke oven emissions. Foods that contain small amounts of PAHs include smoked, barbecued, or charcoal-broiled foods, roasted coffees, and sausages.

Air pollution

Classes of PAHs in the environment include:

1. Biogenic (minor)

  • Produced by living organisms, like vegetation

2. Petrogenic

  • Generated by geological processes
    • NATURAL- seeps, coal outcrops
    • ANTHROPOGENIC - Crude oil spills, fossil fuel release

3. Pyrogenic

Generated by high temperature combustion of organic matter

  • NATURAL – forest fires, paire fires
  • ANTHROPOGENIC - Wood stoves, car exhaust, coal tar

What happens to PAHs in the environment?

  • PAHs enter the air mostly as releases from volcanoes, forest fires, burning coal, and automobile exhaust.
  • PAHs can occur in air attached to dust particles.
  • Some PAH particles can readily evaporate into the air from soil or surface waters.
  • PAHs can break down by reacting with sunlight and other chemicals in the air, over a period of days to weeks.
  • PAHs enter water through discharges from industrial and wastewater treatment plants.
  • Most PAHs do not dissolve easily in water. They stick to solid particles and settle to the bottoms of lakes or rivers.
  • Microorganisms can break down PAHs in soil or water after a period of weeks to months.
  • In soils, PAHs are most likely to stick tightly to particles; certain PAHs  move through soil to contaminate underground water.
  • PAH contents of plants and animals may be much higher than PAH contents of soil or water in which they live.

What is the connection between PAHs and human health?

PAHs are a human health concern.  A number of studies show increased incidence of cancer (lung, skin, and urinary cancers) in humans exposed to PAH mixtures.

Many individual PAH compounds have been classified as probable or possible carcinogens by entities such as the National Toxicology Program and the Environmental Protection Agency (EPA).

Health effects of PAHs

The effects on human health will depend mainly on the extent of exposure (length of time, etc), the amount one is exposed to (or concentration), the innate toxicity of the PAHs and whether exposure occurs via inhalation, ingestion or skin contact. A variety of other factors can also affect health impacts from such exposure, including pre-existing health status and age.

The ability of PAHs to induce short-term health effects in humans is not clear. Occupational exposures to high levels of pollutant mixtures containing PAHs has resulted in symptoms such as eye irritation, nausea, vomiting, diarrhea and confusion. However, it is not known which of the mixture components were causing these effects. Mixtures of PAHs are known to cause skin effects in animals and humans such as irritation and inflammation. Anthracene, benzo(a)pyrene and naphthalene are direct skin irritants while anthracene and benzo(a)pyrene are reported to be skin sensitizers, i.e. cause an allergic skin response in animals and humans.

Seventeen individual PAHs get more attention because of possiblity of exposure and harmful health affects.  These 17 PAHs are:

  • acenaphthene
  • acenaphthylene
  • anthracene
  • benz[a]anthracene
  • benzo[a]pyrene
  • benzo[e]pyrene
  • benzo[b]fluoranthene
  • benzo[j]fluoranthene
  • benzo[g,h,i]perylene
  • benzo[k]fluoranthene
  • chrysene
  • dibenz[a,h]anthracene
  • fluoranthene
  • fluorene
  • indeno[l,2,3-c,d]pyrene
  • phenanthrene
  • pyrene
For more information, go to the
ATSDR Complete Profile for PAHs
and click on the Health Effects.

How might I be exposed to PAHs?

  • Breathing air containing PAHs in the workplace of coking, coal-tar, and asphalt production plants; smokehouses; and municipal trash incineration facilities.
  • Breathing air containing PAHs from cigarette smoke, wood smoke, vehicle exhausts, asphalt roads, or agricultural burn smoke.
  • Coming in contact with air, water, or soil near hazardous waste sites.
  • Eating grilled or charred meats; contaminated cereals, flour, bread, vegetables, fruits, meats; and processed or pickled foods.
  • Drinking contaminated water or cow's milk.
  • Nursing infants of mothers living near hazardous waste sites may be exposed to PAHs through their mother's milk.

Exposure Pathways - Image from ATSDR

What can I do to minimize my exposure to PAHs?

Since PAHs are found throughout the environment, it is difficult to avoid exposure. However, you can significantly reduce  exposure by avoiding certain areas and by modifying some home and recreational activities. The following are practical and easy steps you can follow to reduce PAH exposure.

  • Avoid smoke from wood fires, whether from home heating or for recreational purposes.
  • Avoid exposure to automobile exhaust and areas of high traffic congestion.
  • Avoid areas where asphalt road construction or tar roofing is occurring.
  • If you smoke, smoke outdoors and in areas away from children. Avoid areas where your child may be exposed to secondhand smoke.
  • Prepare foods by slower cooking over low heat, rather than by charring or grilling food.
  • Avoid skin contact with soot.

Note: Workers involved at the oil spill cleanup sites are covered by OSHA's Hazardous Waste Operations and Emergency Response standard (1910.120 and 1926.65). This standard requires that workers be provided protective equipment and special training by specially trained personnel who have received extensive training.

Abstract

An estimated 4.1 million barrels of oil and 2.1 million gallons of dispersants were released into the Gulf of Mexico during the Deepwater Horizon oil spill. There is a continued need for information about the impacts and long-term effects of the disaster on the Gulf of Mexico. The objectives of this study were to assess bioavailable polycyclic aromatic hydrocarbons (PAHs) in the coastal waters of four Gulf Coast states that were impacted by the spill. For over a year, beginning in May 2010, passive sampling devices were used to monitor the bioavailable concentration of PAHs. Prior to shoreline oiling, baseline data were obtained at all the study sites, allowing for direct before and after comparisons of PAH contamination. Significant increases in bioavailable PAHs were seen following the oil spill, however, preoiling levels were observed at all sites by March 2011. A return to elevated PAH concentrations, accompanied by a chemical fingerprint similar to that observed while the site was being impacted by the spill, was observed in Alabama in summer 2011. Chemical forensic modeling demonstrated that elevated PAH concentrations are associated with distinctive chemical profiles.

Children are Vulnerable

Environmental hazards are especially harmful to children. They eat, drink, and breathe more than adults on a pound for pound basis. A child’s nose and mouth are closer to the ground than the nose and mouth of an adult; so children more easily breathe in pollutants in the air, which may accumulate close to the ground if they are heavier than air. Because children play on the ground, they are more likely to have skin contact with pollutants than adults. Toddlers may crawl and as a result, may get contaminated soil, sand and other substances on their hands and clothes. They may have increased exposure if their hands aren't washed before eating, if they put their hands in their mouths after crawling through a contaminated area or if there's absorption of chemicals across the skin from clothing, etc.

Children are in a critical period of development when toxic exposures can have profound negative effects, and their exploratory behavior often places them in direct contact with materials that adults would avoid. In the aftermath of an oil spill, particular attention should be paid to physical dangers, water contamination, and exposure to substances or situations that ould potentially harm children. This situation may become more complex if there are hurricanes/storms or floods.

Steps to Take to Protect Children from Hazards

The oil spill in the Gulf Coast may expose children to a number of hazards and concerns. Until the oil spill is resolved, the following should be kept in mind:

  • The US Environmental Protection Agency (US EPA) is undertaking an increasing amount of testing of environmental air, water, and soil/sediment for various substances ranging from volatile organic compounds or VOCs to particulate matter to Sulfur containing compounds. These substances have the potential to cause various health effects depending upon the level of exposure, the duration of exposure, and the susceptibility of the individuals exposed.
  • The Centers for Disease Control and Prevention (CDC) is providing health guidance based upon these results.
  • It is important to keep in mind the unique factors described above that may render children especially vulnerable. Parents and caregivers should follow the state health department and local health department and CDC reports and recommendations closely and should urge their children to do the same.
  • Local Poison Control Centers (1‐800‐222‐1222 or www.aapcc.org ) are available to respond to questions related to acute exposures.
  • The PEHSU Network is available to assist with additional questions, particularly those regarding low dose, long term exposures [888‐347‐2632 or www.pehsu.net].

Recommendations for contact with shore areas or involvement with clean up efforts:

  • Children should not be allowed to play in or around areas where the water or beach contains oil or sludge.
  •  Adults should handle clean‐up efforts, including issues related to animals or birds expto the oil.
  • Children, and whenever possible teens, should not be involved in clean‐up efforts but should only return after the area is cleaned up. In short, children should be the last group to return to areas impacted by oil or other toxic substances.

Potential for unknown risk:

There may be unknown risks or health effects from exposure to the oil or other toxic agents.

  • The potential for contamination of food and drinking water sources and supplies exists, and local residents should be attentive and follow any health alerts or advisories from authorities.
  • Neither children nor anyone else should eat fish or seafood from oily waters.

The oil washing up on shore is referred to as weathered oil. This means it has not only been mixed with seawater but also exposed to sunlight and air. It is not like crude oil coming out of the ground or refined oil like motor oil. For parents and health care providers, understanding the potential risks to children is difficult because so little is known about the toxicity of weathered oil and the resulting weathered oil mixed with sand which are often called “tar balls”. According to the National Institute for Occupational Safety and Health (NIOSH) skin and respiratory problems were the most common complaints from workers who cleaned up previous spills, but little is known about long‐term effects. It is prudent to restrict children from touching or playing with oil that makes its way to shore and from swimming in water contaminated with oil or dispersants. Parents should check with local health officials to determine which beaches or shore areas are affected (see state links on main page).

Frequently asked questions:

1. What if my child is exposed to oil?
Wash hands with soap and water after oil contact. If necessary clean off oil with baby oil or suntan lotion. If these are ineffective, try a low‐toxicity product, such as a citrus-based cleaning agent that states it is safe for use on skin. Do not use gasoline or other dangerous products. Watch for skin or eye irritation.

2. What if there is a bad smell or odor?
The chemicals in the oil can irritate the eyes, nose and throat even at low concentrations. If you smell odors, you should report that information to authorities. For now, if the smell bothers you, stay indoors, close the doors and windows, and turn on your central air conditioning. If you have a indoor w air conditioner, instead of a central unit, it may be better not to use the air conditioner or to turn the settings to the recirculation mode, which closes the outside ventilation feature.

Smelling a bad odor does not automatically mean that the polluted air will cause injury. For many substances related to the spill, the ability to smell an odor may be at levels below those shown, primarily in adults, to cause injury.

There is very little information on these exposures to children, particularly over the long term. Children with chronic respiratory conditions like asthma may be more vulnerable. The most recent data, as of June 16, 2010, indicates that air levels of volatile organic compounds, semi‐volatile organic compounds, and sulfur containing compounds are below occupational health references but may be above some individual’s odor threshold. In addition, these levels may change over time as conditions in the gulf are changing. It is prudent, therefore, to periodically recheck monitoring information.

3. Should I wear a face mask of some kind?
Wearing a face mask (surgical mask, N95 respirator, etc.) is not recommended and will not help with the smell. The chemicals that can be smelled from the oil spill are called volatile organic compounds or VOCs and can only be filtered by an activated charcoal mask. If you are officially involved with clean up, you should follow the protection and mask recommendations of the authorities involved with the clean up.

4. My child has asthma, what should I do?
Children with asthma may be more sensitive to health effects from breathing polluted air than others. In general, consult with your primary care provider. As always, consult your local health department for ozone alert and other routine air pollutant levels as well as allergen levels if your child has these as potential triggers. In addition, check as described above for any oil spill specific coastal air monitoring data. When in doubt, avoid directly affected beach and coastal areas.

5. What about seafood contamination?
Crude oil has the potential to taint seafood with flavors and odors caused by contamination with hydrocarbon chemicals and render seafood unfit to eat. Federal and State authorities are monitoring the waters from which seafood is harvested and they have already closed some areas to commercial fishing.

It is very important to learn about changing closures and to strictly obey all fishing and oyster bed restrictions. As of June 16, 2010, seafood caught in areas that remain open for fishing are recognized by public health and food experts as being safe to eat. However, to be safe, follow the usual rules and do not eat food that has an unpleasant or unusual smell or that astes differently than expected.

6. Is it safe for my children to play on the beach or go in the ocean?
Oil is coming up on some beaches around the gulf coast, but most beaches are so far free of ontamination. Before heading to the beach, it’s a good idea to check with local or state authorities about beach conditions. The US EPA and local authorities are closely monitoring the situation

Common sense would suggest that beachgoers should avoid swimming in water that's visibly contaminated by oil. Remember that children tend to swallow water when they swim unlike most adults. Crude oil contains many toxic chemicals, including volatile and semi‐volatile organic compounds. Fresh crude oil is a skin irritant that may cause redness, burning and even ulcers with prolonged contact. Not surprisingly, children can be more vulnerable to environmental contaminants than adults. Fortunately the more toxic chemicals tend to disperse and evaporate and the spill is far off shore.

Most of the oil washing up along the coast has been ‘weathered’ into tar balls that are less toxic. Even so, it is prudent to discourage your children from touching or playing ith any tar balls or oil slicks. Though the oil washing up on the beaches probably isn't as harsh, it's till a good idea to keep it off your skin.

7. How long should children be allowed to play outdoors when we can smell the oil?
Some children may be more sensitive to health effects than others, particularly children with asthma. As long as public health authorities continue to report extremely low levels of air contaminants, outdoor play continues to be appropriate. Each child, however, should be considered individually, recognizing that parents should minimize exposure if odors prove irritating.

8. Is my water safe to drink?
The oil spill is currently not expected to affect drinking water. Experts do not expect oil to migrate far enough up the Mississippi River to where drinking water intakes begin, but of course this situation could change. If you live near that region or even just visiting, pay attention to information being distributed by local authorities and water utilities. If you use well water, oil is not expected to impact domestic wells. If you detect any changes in the taste or smell of your water, contact your water supplier. If you have a private well, consider getting your water tested and seek a different source of drinking water in the unlikely event of contamination.

9. Members of my family are working on cleanup. Are there precautions we should take?
There is no indication of exposures being brought home on clothes from clean‐up works. However, simple precautions can be taken. If workers have been wearing protective outwear, they should remove it before entering either their home or family car. If they are not wearing protective outwear, whenever possible, workers should shower and change clothes before entering the family car or home. When this is not possible, they should shower immediately upon returning home and their work clothes should be washed separately from family laundry.

Talking to Children and Helping them to Cope is Important

  • When children are exposed to situations that are beyond the scope of their usual experience, they may have difficulty understanding and coping with the events.
  • Talking to children about the oil spill can help them understand the situation, including the risks they may be exposed to on a day‐to‐day basis, and what they can do to keep themselves safe.
  • Some children may develop a range of stress‐related symptoms. For example, it may be upsetting for them to see dead or oil‐covered birds or animals. Adults may need to take steps to promote adjustment and help children cope.
  • Some children may develop a range of stress‐related symptoms. Parents should watch for signs of stress such as sleep difficulties, behavior pattern change, change in school performance, increased fighting with siblings, and substance abuse. It is important to make your child’s doctor aware if your child or teen develops any of these problems. Adults may need to take steps to promote adjustment and help children cope. Raising a family and taking care of children is challenging when there are tough economic conditions. Children can sense stress and become anxious or upset if no one communicates with them. Adults should talk to kids about the economy and the potential economic effects of the oil spill.
  • Communities may need to designate or identify outdoor areas (parks, playgrounds, yards, etc.) that are clean and free from safety and environmental hazards. This would include ensuring that routes to and from living, learning, and playing places are cleaned and made free of safety and environmental hazards.

Dispersants and Your Health

What are oil spill dispersants?
Oil spill dispersants are products that break an oil slick into small drops and stop the oil from coming back together to make a new slick. They do not remove oil from water but they do make it easier for nature to break down the oil. Broken down oil is less likely to stick to animals, rocks, and plants.

How are oil spill dispersants used?
Oil spill dispersants are sprayed on top of a slick from planes and ships. They can also be forced under the surface of the water to break up oil before it reaches the surface.

What are the health threats of oil spill dispersants?
For most people brief contact with a small amount of oil spill dispersants will do no harm.

If your skin is exposed to dispersants for a long time, a rash and dry skin could develop. Dispersants can also irritate your eyes.

If you breathe in dispersants for a long time or several times they can irritate your nose, throat, and lungs.

Swallowing dispersants will cause upset stomach, vomiting, and diarrhea.

If you are exposed to dispersants for a long time or several times they can also cause central nervous system effects; sleepiness; damage to your blood, kidney or liver; and a metallic taste in your mouth.

How can I avoid the health threats of oil spill dispersants?
Most people will not be exposed to enough oil spill dispersants to be affected.

If you are working on the spill, wear nitrile or PVC gloves, coveralls, boots, and chemical splash goggles to keep dispersants off your skin and out of your eyes.

If you breathe in dispersants, move to an area where the air is clearer.

If you get dispersants on your skin, immediately wash with soap and water. If symptoms develop, seek medical attention.

If you get dispersants in your eyes, flush them with water for 15 minutes.

If you swallow dispersants, do not try to vomit, as this may get dispersants into your lungs and cause pneumonia. Wash out your mouth with water and seek medical attention.
