The Experience Of Reducing Environmental Risks In An Environmental Justice Community, Gabriela Dory

Dissertations

Research on Environmental Justice (EJ) communities has focused on quantitative assessment of environmental hazards and general physical health problems. Little is known about how individuals living in EJ communities perceive their environmental risks and how they reduce environmental risks. The purpose of the study is to explore and describe the perceived environmental risks and the experience of reducing environmental risk among individuals living in an EJ community.

A qualitative and longitudinal design with a descriptive phenomenological method is used to recruit 23 participants living in a known EJ community in the urban area of New Jersey. A total of 43 …

Uncertainty Analysis In Ecological Risk Assessment Modeling, Tepwitoon Thongsri

Dissertations

A probabilistic approach employing Monte Carlo simulations for assessing parameter and risks as probabilistic distributions was used in an ecological risk assessment (ERA) model to characterize risk and address uncertainty. This study addresses the following sources of uncertainty: parameter inputs in the ERA models, risk algorithms and uncertain input concentrations. To achieve this objective, both sensitivity and uncertainty analyses are being conducted. Monte Carlo simulations were used for generating probabilistic distributions of parameter and model uncertainty. All sensitivity, uncertainty, and variability analyses were coded in Visual Basic as part of the ERA model software version 2001, which was developed under …
