    Delineation of a Potential Gaseous Elemental Mercury Emissions Source in Northeastern New Jersey: Research Project Summary
    (Trenton, N.J. : New Jersey Department of Environmental Protection, Office of Science, 2013-05) Reinfelder, John R.; Wallace, William; Aucott, Michael; Polissar, Alexander
    In order to assist in the identification of possible mercury (Hg) emission sources in northeastern New Jersey, this project was undertaken to delineate geographic areas in which these sources may be located. The objectives of this project were to measure gaseous elemental mercury (GEM) concentrations at a site on Staten Island, New York to the east of the putative emissions source and analyze these results with those obtained by the NJDEP at their air monitoring site (ELAB) in Elizabeth, New Jersey. Additional local measurements were to be obtained near possible emission sources. From September 30, 2011 to September 3, 2012, GEM data were collected for more than 200 days at the Staten Island site. Together with wind speed and direction data from the NOAA Bergen Point West Reach naval observatory station these measurements were analyzed and transport trajectories of GEM in the region were determined. GEM concentration and wind direction data from the ELAB site for the same period of time were also analyzed. Local measurements of GEM in the area were limited by access to appropriate sites and difficulties maintaining stable calibration of the portable Hg analyzer. Directional analysis of the number frequency and concentration-weighted distributions of GEM peaks with concentrations >4 ng m-3 at the ELAB site revealed a single source located to the south of the sampling site (bearing 173.4°). Similar analysis of GEM results for the Staten Island site revealed two possible sources, one to the west (bearing 280.5°) and a second to the southwest (bearing 213.8°). The intersections of the two Staten Island transport trajectories with the ELAM trajectory delineate two possible GEM source areas. The first is centered in Rossville, NY on Staten Island (40.5514 N, 74.1947 W) and the second near Pralls Island in the Arthur Kill along the eastern border of Linden, NJ (40.6119 N, 74.2039 W). Temporal analysis of GEM peaks for the three source directions indicates that the eastern Linden source may contribute more GEM to elevated measurements recorded in Elizabeth than the Rossville source.

    The New Jersey Atmospheric Deposition Network (NJADN)
    (Trenton, N.J. : New Jersey Department of Environmental Protection, 2004-01) Reinfelder, John R.; Totten, Lisa A.; Eisenreich, Stephen J.
    The New Jersey Atmospheric Deposition Network (NJADN) was a collaborative environmental research and monitoring effort between Rutgers University and the New Jersey Department of Environmental Protection (NJDEP). The objectives of the project were to quantify current concentrations and deposition fluxes of atmospheric chemicals and assess their spatial and seasonal trends. The evaluation of the potential impact of atmospheric deposition to terrestrial and aquatic ecosystems and the identification of local and regional sources of atmospheric contaminants were also implicit goals of the project. Ultimately NJADN results will establish baseline levels of atmospheric chemicals that will be useful in the evaluation of long-term trends and the effectiveness of pollution control efforts.

    New Jersey Atmospheric Deposition Network: Research Project Summary
    (Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Science, Research and Technology, 2005-04) Reinfelder, John R.; Totten, Lisa A.; Eisenreich, Steven J.; Aucott, Michael
    Atmospheric deposition is an important source of a number of contaminants to the environment. The New Jersey Atmospheric Deposition Network (NJADN) was a collaborative research and monitoring effort between Rutgers University and the New Jersey Department of Environmental Protection (NJDEP). The objectives of the project were to quantify current concentrations and deposition fluxes of targeted contaminants and assess their spatial and seasonal trends, and, to the extent possible, to determine the importance of atmospheric deposition relative to other inputs. Contaminants measured included PCBs, PAHs, certain organochlorine pesticides, heavy metals, nutrients, and organic and elemental carbon particles. NJADN results have established baseline levels of the organic contaminants in the gas, particle, and precipitation phases and of the metals, nutrients, and organic and elemental carbon in the particle and precipitation phase. These baseline levels will be useful in the evaluation of long-term trends and determining the effectiveness of pollution control efforts.
