Still Killing the Gulf

BP’s oil disaster last summer gushed at least 4.9 million barrels of oil into the Gulf of Mexico, causing the largest accidental marine oil spill in history - and the largest environmental disaster in US history. Compounding the problem, BP has admitted to using at least 1.9 million gallons toxic dispersants, including one chemical that has been banned in the UK.

According to chemist Bob Naman, these chemicals create an even more toxic substance when mixed with crude oil. Naman, who works at the Analytical Chemical Testing Lab in Mobile, Alabama, has been carrying out studies to search for the chemical markers of the dispersants BP used to both sink and break up its oil.

Poly-aromatic hydrocarbons (PAHs) from this toxic mix are making people sick, Naman said. PAHs contain compounds that have been identified as carcinogenic, mutagenic, and teratogenic.

“The dispersants are being added to the water and are causing chemical compounds to become water soluble, which is then given off into the air, so it is coming down as rain, in addition to being in the water and beaches of these areas of the Gulf,” Naman told Al Jazeera.

“I’m scared of what I’m finding. These cyclic compounds intermingle with the Corexit [dispersants] and generate other cyclic compounds that aren’t good. Many have double bonds, and many are on the EPA’s danger list. This is an unprecedented environmental catastrophe.”

Pathways of exposure to the chemicals are inhalation, ingestion, skin, and eye contact.

Many of the chemicals present in the oil and dispersants are known to cause headaches, nausea, vomiting, kidney damage, altered renal function, and irritation of the digestive tract. They have also caused lung damage, burning pain in the nose and throat, coughing, pulmonary edema, cancer, lack of muscle coordination, dizziness, confusion, irritation of the skin, eyes, nose, and throat, difficulty breathing, delayed reaction time and memory difficulties.

Further health problems include stomach discomfort, liver and kidney damage, unconsciousness, tiredness/lethargy, irritation of the upper respiratory tract, hematological disorders, and death.

”There is still a large amount of crude in the marshes and buried on the beaches. As long as that pathway is there for exposure, these problems will continue quite a long time into the future."
