But NOT ALL.
Since we've established that dissolved solids don't evaporate, that means COREXIT CANNOT evaporate.
That's like saying that since some people have auto accidents frequently, all people have auto accidents frequently.
It's convenient to claim IF A THEN B, when you leave the details out of A which would negate your conclusion.
Can the components of COREXIT that are fluids or gas evaporate?
If COREXIT is completely a solid, how do they pour it out of a drum, and pump it through a hose?
I'm sure some can. I already pointed out that ethanol, one of the chemical compounds found in COREXIT is highly volatile, and would evaporate quickly once it reached the surface of the water.
But, you have to account for relative volume. As I said, whatever volatile chemicals escape into the atmosphere from the application of dispersant, pale in comparison to the volatile (and hazardous) chemicals that escape into the air from people putting fuel in their cars each hour.
Simply stated, the additional volatile chemicals introduced into the atmosphere from COREXIT is less than negligible compared to what's introduced during any other normal day in that part of the country.
