The primary purpose of this study was to characterize the polycyclic aromatic hydrocarbon concentrations found in soils across New Jersey where the population density was 2,000 people per square mile or greater and in areas not known to be directly impacted by a discharge or historic fill. The large majority of the concentrations measured did not exceed the lowest levels of regulatory concern. Typically, surface concentrations exceeded subsurface concentrations at a given location. Although not the primary focus of the study, assessments of railroad track beds and asphalt surfaces as sources of polycyclic aromatic hydrocarbons were secondary purposes. Naphthalene concentrations decreased with increased distance from railroad track beds. Several polycyclic aromatic hydrocarbons decreased with increasing distance from asphalt surfaces.
NJRisk: Development of an Integrated Computational Tool to Support Prioritization of Chemicals of Emerging Concern: Research Project Summary
(2019-10) Georgopoulos, Panos G.; Mueller, Robert
The objective of the NJRisk project is to develop, test, and deploy an integrated tiered system coupling computational platforms to support prioritization of Chemicals of Current and of Emerging Concern for assessment by the NJDEP. A nine-month pilot study was conducted from July 2013 to March 2014 in order to complete the necessary groundwork for the subsequent implementation. The full study, which began in April 2014, uses two operational computational platforms for hazard and exposure ranking, METIS (Metanomics Information System), developed by DuPont, and PRoTEGE (Prioritization and Ranking of Toxic Exposures with GIS Extension), developed by the Computational Chemodynamics Laboratory of the Environmental and Occupational Health Sciences Institute (EOHSI), respectively. This effort also takes advantage of, and incorporates in the development of the new system, current and anticipated outcomes of ongoing efforts by federal agencies, such as the USEPA. The goal is to implement an integrated software platform or “tool” (NJRisk) that will allow users to assess both hazard and exposure potentials of chemicals that are found (or could be introduced) in the New Jersey environment and/or biota, and to prioritize these chemicals for regulatory action based on tiered risk analysis.
