Five of the 57 ingredients in dispersants approved by the U.S. Environmental Protection Agency for use on oil spills are linked to cancer, finds a new research report based on data obtained through a Freedom of Information Act request by environmental groups on the Gulf of Mexico. The report from Earthjustice, an environmental law firm, along with Toxipedia Consulting Services, is based on material released by the U.S. EPA in response to a Freedom of Information Act request made by Earthjustice on behalf of the Gulf Restoration Network and the Florida Wildlife Federation. Dispersants are used to clean up oil spills and contain chemicals that break up oil into smaller droplets and move the oil from the surface of the water into the water column.
Two oil dispersant products were used heavily in the BP oil leak: COREXIT 9500 and 9527, both produced by Nalco/Exxon. BP used over 1.8 million gallons of dispersant during the three-month long oil leak that gushed 4.9 million barrels of crude oil from the Macondo well located about 40 miles southeast of the Louisiana coast. The report "The Chaos of Clean-Up: Analysis of Potential Health and Environmental Impacts of Chemicals in Dispersant Products" highlights the fact that some dispersants are safer than others. "The testing can't be done in the moment of the disaster," said Marianne Engelman Lado, an attorney with Earthjustice. "It has to be done ahead of time to avoid the chaos we witnessed during the disaster response to the Deepwater Horizon disaster."
Among the dispersant chemical ingredients linked to cancer are:
Amides, coco, N,N-bis(hydroxyethyl), which is classed as a likely carcinogen Cyclohexene, 1 - methyl - 4 - (1 - methylethenyl) -, (4R) -, which is classed as carcinogenic to rats Ethanol, 2-butoxy- which is listed as a possible carcinogen Petroleum distillates, hydrotreated light, which are classed as a confirmed animal carcinogens with unknown relevance to humans. These distillates carry the additional warning that exposure by inhalation can cause dizziness, headache, nausea, drowsiness, and unconsciousness and prolonged inhalation of high concentrations may damage the respiratory system.
Gulf residents continue to suffer health effects related to the disaster clean-up. "The illnesses we observed were quite unique and different from anything that I had ever witnessed before," said Dr. Michael Robichaux, a physician in Raceland, Louisiana. "Although there were scores of complaints early on, the main problems at this time are a loss of memory, seizure type problems, severe abdominal pain, fatigue, irrit
