... Wilma Subra, a chemist who has served as a consultant to the Environmental Protection Agency, said there was growing anecdotal evidence that locals were falling ill after exposure to tiny airborne particles of crude. Air quality data released earlier by the EPA suggested the presence of chemicals that – while still within legal limits – could be dangerous. But Subra complained that the EPA was not releasing all data it had gathered from BP.
"Every time the wind blows from the south-east to the shore, people are being made sick," she said. "It causes severe headaches, nausea, respiratory problems, burning eyes and sore throats." Long-term health effects include neurological disorders and cancer.
Subra said there was even greater concern for those recruited to lay booms and skim crude off the water, since they were in closer proximity to the oil and the chemical dispersants.
Clint Guidry, of the Louisiana Shrimp Association, has accused BP of threatening to sack workers who turn up wearing respirators. The oil firm said it was not aware of any workers being turned away, but noted that it was the responsibility of the Obama administration to decide whether such protective gear was warranted.
Hugh Kaufman, chief investigator for the EPA's ombudsman, said he encountered similar worker safety policies after 9/11. "If people are wearing respirators, it scares people because they realise how toxic it is," he said "The administration is down-playing the problem because it saves them money down the line. It was the same at Ground Zero."http://www.guardian.co.uk/environment/2010/may/28/bp-gulf-oil-spill-pollution
