Are chemical dispersants affecting those involved with the Gulf oil spill cleanup? Some Louisiana fishermen are reporting headaches, burning eyes and nausea, Fox News reports.

Fisherman Gary Burris said he got sick and disoriented after breathing in the dispersants used to break up the oil, the story says. "It filled my lungs with fluid," he said. "I'm hurting — I'm sore from coughing."

Riki Ott, a marine toxicologist who's heard from other fishermen with similar symptoms, said illness can result from overexposure to crude oil and cleanup chemicals.

"This is like throwing kerosene on a fire," Ott told Fox.

British Petroleum has sprayed more than 800,000 of gallons of dispersant into the Gulf since the spill began April 20 when the Deepwater Horizon oil rig exploded.

BP's "Vessels of Opportunity" program, which employs fishermen to help with the cleanup, has come under fire from critics who say safety training for workers isn't sufficient, according to Fox.
