Enhanced atmospheric deposition of particulate and gaseous PCBs and PAHs to southern Lake Michigan during AEOLOS
- Rutgers Univ., New Brunswick, NJ (United States); and others
The project Atmospheric Exchange Over Lakes and Oceans (AEOLOS) was formed to evaluate the hypothesis that emissions of hazardous air pollutants (HAPs) into the coastal urban atmosphere increases atmospheric depositional fluxes to adjacent Great Waters. As part of this project, measurements of {Sigma}PCBs + congeners and {Sigma}PAHs + 24 individual compounds were performed in southern Lake Michigan on air filters and PUF adsorbents at three locations: south Chaicag, over the lake at 10-15 km west, and at South haven across the lake. Intensive experiments were conducted in May and July 1994 and January 1995. The data reported here were used to investigate atmospheric concentration gradients from the source area to the receptors, estimate air-water exchange fluxes at the lake site and estimate dry depositional fluxes using dry deposition plates. The intensive experiments support the hypothesis that {Sigma}PCBs and {Sigma}PAHs loadings to southern Lake Michigan are large, not assessed as part of the IADN monitoring network, and are large even on a whole-lake scale.
