But what they are dissolved IN, does EVAPORATE.
Don't tell me you don't understand that 'process'.
Now, which of the chemicals in COREXIT is a solid?
I think a brief explanation of a colloidal suspension or emulsion would be helpful to those here who do not understand that two liquids are miscible (that’s chemistry for the mix into each other). An example of an emulsion is milk, a liquid with fat, water, sugars, hormones, casein protein as well as dissolved vitamins and minerals. The fat is emulsified into the water solution, that is, the fat is made able to be mixed into the water by the action of an emulsant. The dispersant works in a similar manner making smaller particles of crude oil able to be held in solution in small globules. When the water evaporates away you are left with a mass of various solids. In the case of this crude the “solids” are food for bacteria that target these solids.
I have no idea, nor is it really relevant. BUT, you are starting to understanding. There are clearly compounds in COREXIT that are dissolved solids. Since we've established that dissolved solids don't evaporate, that means COREXIT CANNOT evaporate.
Are there compounds present in COREXIT that might evaporate? Sure. Let's take one of the compounds - Ethanol. Ethanol is volatile as hell. What does that mean? It means it easily vaporizes. But, does vaporized ethanol pose any danger to the environment, or to plants some 700 miles away? Not on your life. We lose more volatile chemicals into the atmosphere from people pumping their gas in the Southeast each hour, than from ALL the COREXIT used since this spill began.
In fact, during mid-day summer months, large cities all across the south ask people to avoid filling up their gas tanks because of the volatility of gas and the atmospheric phenomenon it contributes to called smog.
To posit that people and plants face a danger because of the evaporation of oil dispersant introduced into the Gulf of Mexico and evaporating is somehow greater than the volatility of the gas those people pump into their cars each hour, is patently absurd.
