The U.S. Agency for Toxic Substances and Disease Registry (ATSDR) recently released two new Interaction Profiles for Toxic Chemical Mixtures, continuing a long-running federal effort to better understand the health effects of exposures to combinations of hazardous substances rather than individual chemicals in isolation. The two new profiles evaluate mixtures commonly encountered in environmental and indoor air contexts: Chloroform, 1,1-dichloroethylene (1,1-DCE), trichloroethylene (TCE), and...
