Experts criticize flawed dioxin testing plan near Ohio train derailment site.

A plan to test for toxic dioxins near the site of a February train wreck in East Palestine, Ohio, is flawed and unlikely to find the dangerous substances, independent chemical pollution researchers in the US who reviewed the testing protocol told the Guardian. The plan relies on an “unconventional” process to check for dioxins, and the results are “unlikely to give a complete picture” of contamination in East Palestine, said Stephen Lester, a toxicologist with the Center for Health, Environment and Justice.
