Risk Assessment Case Study Evaluation The risk assessment case study evaluates the chromium-contaminated soils. Twelve years of research went into the study to characterize the health hazards caused by the chromium-contaminated soils. Within New Jersey there were at least three different chromate chemical manufacturing companies operating, one in Kearny, New Jersey, and the other two in Jersey City. The study was conducted through a human health risk assessment, which

Influencing issues are a variable in the second step, such as; age, gender, routines, the amount they are exposed, and the volume that they are exposed. “A dose-response relationship describes how the possibility and severity of adverse health effects are related to the amount and condition of exposure to an agent” (EPA, 2012, p.1). The third step is the exposure assessment. “Exposure assessment is the process wherein the intensity, frequency, and duration of human exposure to an agent are estimated” (Paustenbach, 2002, p.1). Last, the final step is the risk characterization. The hazardous effect on health is labeled in the final phase. By calculation and educated guesses, the incidence of a health effect under the various conditions of human or animal exposure described in the exposure assessment is defined. The community has not been significantly affected by the COPR – containing soils. “The property values have been kept intact and the businesses on affected properties have continued to operate” (Paustenbach, 2002, p.1). When the COPR was ub the process of disposal, there was little or no concern for the environmental and human health risks that would occur as a result of the distribution of COPR outside the plant.
