    Chromium Exposure and Health Effects in Hudson County: Phase I: Research Project Summary
    (Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Science, Research and Technology, 2008-12) Lioy, Paul J.; Gochfeld, Michael; Fan, Zhi-hua (Tina); Shalat, Stuart L.; Black, Kathy; Lin, Lin
    During much of the twentieth century, Hudson County, and particularly Jersey City, was one of the world centers of chromate production from chromite ore. The slag and waste products from this production referred to as COPR (chromite ore processing residue) was disposed in various locations and given away gratis for fill, berms etc. This resulted in a legacy of approximately 200 COPR waste sites in Hudson County. COPR contains variable amounts of hexavalent chromium (Cr+6) as well as trivalent chromium (Cr+3). Cr+6 is a known human inhalation carcinogen (USEPA, 1998). Recent evidence indicates that it is also an ingestion carcinogen (NTP, 2008). Because of its carcinogenic potential, Cr+6 is the substance of greatest concern in COPR.

    An Evaluation of Potential Exposures to Lead and Other Metals as the Result of Aerosolized Particulate Matter from Artificial Turf Playing Fields: Research Project Summary
    (Trenton, N.J. : New Jersey Department of Environmental Protection, Office of Science, 2011-08) Shalat, Stuart L.; Stern, Alan H.
    In response to numerous community concerns starting in 2008 regarding the safety of artificial turf fields, the New Jersey Department of Environmental Protection (NJDEP) funded a study by the Environmental and Occupational Health Sciences Institute (EOHSI) to measure lead (Pb) concentrations in wipe samples and in air at artificial turf fields. Sampling was conducted at five fields in New Jersey using an autonomous, programmable robot that agitated the turf surface and collected air samples above the turf in the breathing zone of a child. Other potentially toxic metals were also measured including chromium, cadmium and arsenic. Although considerable efforts were made to gain access to more fields, schools and community facilities were reluctant to participate. Pb was significantly elevated at one of the five fields. Although the measured levels of Pb at this field did not approach standards for protection of health, the small number of fields sampled makes it difficult to generalize the conclusions of this study to other artificial turf fields. On the basis of these results, it is recommended that artificial turf fields, particularly those older than three years, be screened for Pb using wipe sampling. If wipe samples show elevated levels of Pb, more intensive sampling of air with agitation of the turf is recommended.
