Bacteria that degrade PCBs in sediment can reduce chemical emissions to surrounding air

30 Oct 2022

Adding bacteria that can break down polychlorinated biphenyls (PCBs) to contaminated sediments reduced the release of the chemicals into surrounding air, according to NIEHS-funded researchers. The approach may decrease PCB inhalation exposure near PCB-contaminated sites. PCBs are a family of more than 200 structurally similar chemicals that have been linked to a range of adverse health effects, including some cancers.
