The mysterious crop damage farmers in Mississippi began to notice earlier this month could be a combination of acid rain and butane rain, problems that will worsen as BP continues to flare off huge amounts of methane and the hydrocarbons in crude oil come to the surface of the Gulf waters and evaporate. Volatile aromatic hydrocarbons are a component of crude oil, and the use of Corexit has broken oil sludge down into finer particles that are more easily lofted into the atmosphere where they fall back with rain showers. Downwind of that after a rain will smell like an oil refinery, and crops and animals, particularly birds, fresh water fish and snails, will experience the toxic effects of Butane, Corexit and Acid Rain.
This will go on for many months or years as the dispersed oil droplets continue to circulate within the water column and steadily rise to the surface over a wider and wider area of the sea. Corexit has made this problem astronomically worse, and is now beginning to impact life forms on land and fresh water.
It will also exacerbate an already critical ozone smog problem, which has its own toxic effects, including skin cancers.
Massive marine life die offs, beach and waterfront fouling, and crop damage are just the beginning of the catastrophic environmental health problems that are inevitable from a marine crude oil release of this magnitude, particularly with the huge application of dispersants that only spread and complicate the toxic effects of the oil.
