“The suit accuses the EPA of paying as many as 41 participants $12 an hour to breathe in concentrated diesel exhaust, for as long a two hours at a time.”
If they volunteered and signed papers to participate in the experiment, nothing can be done about it. (and lets avoid the “they were too stupid to know breathing in concentrated diesel exhaust, for as long a two hours at a time was bad for them” argument) Lots of people volunteer for experiments,,,trying new medical drugs, for instance.
See post #47 about the consent forms ...none...they didn’t sign any.
