Sources
The ISRP has been a leader in finding sources of airborne PCBs-whether it be from outdoor sources such as hazardous waste sites or contaminated waterways or indoor sources such as light ballasts, caulking, kitchen cabinets, or paint.

Toxicities
The ISRP’s elucidation of metabolic pathways involved in toxification mechanisms aids in understanding targets and levels of pollutants that cause adverse health effects.

Exposure
The ISRP has demonstrated that inhalation is an important route of exposure to PCBs and has discovered which congeners dominate exposure.

Remediation
The ISRP is striving to understand the mechanisms whereby plants and associated rhizosphere bacteria may provide bioremediation of lower chlorinated PCBs from contaminated soils and sediments. (Picture of young poplar plants courtesy of Tim Mattes).
