The higher the dose, the more dangerous the toxin—that principle is the basis for most regulatory chemical testing in the United States. But a new report shows that even low doses of some toxins can be harmful, and that finding could have implications for the long-standing debate over the chemicals used in natural gas drilling and hydraulic fracturing."
