The BP oil spill will subject people in the gulf coast region to different kinds of health risks, both short and long term. 71 have already been hospitalized in Louisiana so far as a result of oil spill. Short term exposure to the vapor is linked to dizziness, eye and throat irritation and asthma. Many more hospitalizations are to come.

Following the Exxon Valdez spill in Alaska in 1989, over 11,000 clean up workers sought medical attention as a result of the exposure. This kind of problem promises to be at least as bad now with the BP disaster, especially when you consider that petroleum distillates in the dispersants (1 million gallons have been reportedly use) may pose an even greater problem especially to workers in terms of skin and lung irritants. And certain kinds of dispersants used (Corexit) contain 2-butoxyethanol, a compound that has been linked to long term kidney and liver problems.

The EPA has asked BP to stop using toxic dispersants, but has been unsuccessful so far.

According to the CDC crude oil waste disintegrates over time, and brief contact will do no harm (except for some skin rashes). In terms of inhalation, as CDC reports, the risk is from volatile hydrocarbons which can lead to headache, dizziness, confusion, nausea, and vomiting.

More concerning is the long term cancer risk that appears to be associated with the hydrocarbons and heavy metals including mercury and lead that some will have prolonged exposure to. These toxins will also find their way into the fish we eat, even if there is a ban imposed.

After the Exxon Valdez spill, a study published in the American Journal of Psychiatry in 1993 showed there was a marked increased incidence of anxiety, depression and PTSD in communities affected. I expect even more of a problem here in the gulf coast states, where the population is far more dense than Alaska, and many will be out of work as the fishing industry collapses.
