Mercury isn't used in drilling and its only widespread uses are in dentistry (as an amalgam) and in gold mining. How did this mercury end up here? Mercury is also very dense and would tend to seep to the bottom on anything so its hard to see how it could be 'washed up".
where did it come from and where was it found
The TX coastline is FILLED with tar sands from the drilling. It gets on your skin and will not come off. It is disgustinf.
Cody's Lab would love to collect some of that
And the EPA is on its last legs right now. WTF are we doing
And this is why people in beach communities with tourist economies oppose offshore drilling.
Mercury like this would be terrible if it got aerosolized, but my understanding is that a globule of it in the mud is not giving off "toxic vapor." Smrt ppl please correct me (or expand on this)
