Particle-associated PCBs in lake Ontario

A study was carried out to evaluate the role of the nepheloid layer in the transport and cycling of PCBs in Lake Ontario in 1987-89 and 1991. Water, suspended matter, and bottom sediment samples were collected at eleven stations in Lake Ontario. The concentrations of t-PCBs in the suspended matter i...

Zusammenfassung:A study was carried out to evaluate the role of the nepheloid layer in the transport and cycling of PCBs in Lake Ontario in 1987-89 and 1991. Water, suspended matter, and bottom sediment samples were collected at eleven stations in Lake Ontario. The concentrations of t-PCBs in the suspended matter in the nepheloid layer ranged from 151 to 728 ng/g (dry wt) in 1987–1989, and were greater than those in most of the top 3-cm sediments (
