I was mostly using Google Scholar to look for peer reviewed work with the keywords 'corexit toxicity' There are a about a dozen papers on the first page, of the ones I could read without jumping various firewalls the conclusions tended toward 'less toxic' than 'more toxic'. Would love to see a meta analysis too but didn't dig one up.

Obviously, but what does that comment have to do with anything? So corexit is harmful. My gp was talking about nuclear explosions and bacteria, not corexit.
