  • How toxic is coal ash? A laboratory toxicity case study

    Under a consent agreement among EPA and proponents both for and against stricter regulation, EPA is to issue a new coal ash disposal rule by the end of 2014. Laboratory toxicity investigations often yield conservative estimates of toxicity since many standard test species are more sensitive than resident species, thus could provide information useful to the rule‐making. However, few laboratory ...
