A one-year study (6/90-7/91) was conducted to estimate the deposition of atmospheric contaminants to the Maryland portion of the Chesapeake Bay. The studied contaminants included the trace elements polychlorinated biphenyl (PCBs) congeners, and polycyclic aromatic hydrocarbons (PAHs). Weekly integrated samples of aerosol and precipitation were collected for elemental constituents at two sites, one on the northeastern (Wye) and one on the mid-bay western (Elms) Maryland shore. Organic contaminants in precipitation samples were collected bi-weekly at the Elms site only. Major elements in wet deposition, as related to acid rain monitoring, are being measured at these sites by other groups.
