Research Briefs
- 330 - Study Sheds Light on Breakdown Products of PCBs in the Environment -- Hornbuckle
Release Date: 06/01/2022NIEHS Superfund Research program (SRP) grantees discovered toxic breakdown products of polychlorinated biphenyls (PCBs) in contaminated sediments at proportionally higher levels than found in commercial PCB mixtures. According to the team, these findings point to environmental processes, such as metabolism by animals, plants, or bacteria, in generating the harmful chemicals.
- 293 - Study Sheds Light on Breakdown of PCBs to Potentially Harmful Metabolites in Humans -- Lehmler
Release Date: 05/01/2019New research out of the University of Iowa Superfund Research Program (SRP) Center identified specific cytochrome P450 (CYP) enzymes and underlying mechanisms involved in the breakdown, or metabolism, of polychlorinated biphenyls (PCBs) into compounds that may be more toxic.
- 291 - Passive Samplers Tackle PCB Flux -- Hornbuckle
Release Date: 03/06/2019Researchers from the University of Iowa Superfund Research Program (SRP) Center have developed a method to measure the movement, or flux, of polychlorinated biphenyls (PCBs) from water to air using passive sampling devices.
