Wet deposition of total phosphorus has been measured as part of the New Jersey Atmospheric Deposition Network (NJADN). Precipitation samples were collected in 1999—2001, using automated wet-only precipitation collectors at four sites in New Jersey, representing different land-use regimes. Total phosphorus volume-weighted mean concentrations (VWM) and the wet depositional fluxes were estimated on seasonal and annual timescales. VWM concentrations (¡À standard error) of total phosphorus ranged from 4.1 ¡À 0.80 to 15 ¡À 8.8 μg L-1 at all sites and were of similar magnitude across the region. The wet deposition flux estimates ranged from 3.9 to 14 mg m-2 y-1. VWM concentrations and fluxes were similar to those measured at other locations in the eastern United States.
