Abstract
Sequencing sediment traps were deployed on Lake Michigan from late August 1998 until late May 1999 as part of the Episodic Events - Great Lakes Experiment (EEGLE) Project. These sequencing traps collected settling material for nine to thirty-day periods before, during, and after a 1999 spring sediment resuspension event. The samples from four of the stations, with field blanks from three different stations, were analyzed for persistent organic pollutants (POPs). The downward flux of sediment mass ranged from 0.014-24.2 g/m super(2)-day for this period, while the flux in sediment associated organic carbon (OC) varied from 0.007-0.457 mg/m super(2)-day. Settling fluxes were evaluated for 109 POPs and generally increased with sediment mass fluxes, which were largest during early November and late December of 1998 and early March of 1999. For example, the flux of the polychlorinated biphenyls ( capital sigma PCBs) ranged from 10.94-1,003 ng/m super(2)-day, and the flux of HCB varied from 0.0406-132.0 ng/m super(2)-day. In this presentation, the trends of these fluxes of persistent bioaccumulating toxics on settling particles will be discussed.
