Description of the Atmospheric Deposition Sites in the New York New Jersey Harbor Estuary

The NJADN was initiated in October 1997 with the establishment of a suburban master monitoring and research site at the New Brunswick meteorological station/Rutgers Gardens near Rutgers University (Fig. 27.2). In February 1998, an identical site was established at Sandy Hook to reflect the marine influence on the atmospheric signals and deposition at a coastal site on the NewYork/New Jersey Harbor Estuary and Raritan Bay. In July 1998, a site was established at the Liberty Science Center in Jersey City to reflect the urban/industrial influence on atmospheric concentrations and deposition in the area of the estuary.

At each land site, a suite of PCB congeners (n = 86) and PAH compounds (n = 34) were measured in atmospheric samples in gaseous and particulate phases, and precipitation; total suspended par-ticulate matter (TSP), PM2.5, and particulate organic carbon and elemental (black or soot) carbon (POC/EC) in PM2.5 aerosol in the majority of samples. Atmospheric samples of gas and particulate phases (organics) were collected one day (24 hours) every twelfth day, and wet-only integrated precipitation was collected over twenty-four days or two air-sampling cycles. Meteorological data were obtained from nearby established meteorological stations.
