The rResults from the first four years of operation of the New Jersey Atmospheric Deposition Network (NJADN) are presented, includeing the first estimates of atmospheric deposition fluxes of a suite of organic (s, includingpolychlorinated biphenyls, (PCBs), polycyclic aromatic hydrocarbons, (PAHs), and organochlorine pesticides, (OCPs)), and inorganic (trace metals, nitrate, phosphate, and mercury) contaminants to the Hudson River Estuary and the New Jersey Meadowlands area.  The NJADN consisted of nine monitoring sites across the state representing a variety of land-use regimes.  Concentrations of organics were measured in air, aerosol, and precipitation at regular intervals from October 1997 through May 2001.  Trace metals and mercury were measured in PM2.5 and rain.  The results demonstrate that concentrations of PCBs, PAHs, and trace metals are elevated in the area surrounding the Meadowlands as compared to more remote areas of the state, leading to high atmospheric inputs of these contaminants to the waters of the Meadowlands.  These atmospheric inputs are large enough that they would, in theory, cause the waters of the Meadowlands to exceed water quality criteria for the protection of human health for compounds such as PCBs, even in the absence of other sources.
