New Studies Question How Much Harm MCHM Can Do

There are new questions about the toxicity of MCHM and other materials involved in the Freedom Industries chemical spill. There’s new evidence that some of the spilled chemicals could affect neurological function or be related to genetic mutations, according to the study’s website. But there’s no proof that the spill chemicals could have that kind of impact on humans. The studies used minnows and other small fish. State health officials are still reviewing the results.
