Risk Metrics and Cumulative Risk Assessment Methodology for the FQPA

Regulatory Toxicology and Pharmacology, 2000
The Food Quality Protection Act (FQPA) of 1996 mandates that the U.S. Environmental Protection Agency consider both aggregate and cumulative risks. Aggregate assessments account for multiple sources and routes of exposure for a single chemical. Cumulative assessments combine exposures to two or more chemicals that share a common mechanism of toxicity ...

Strategies for Assessing Cumulative Ecological Risks

Human and Ecological Risk Assessment: An International Journal, 2001
Assessing and managing the ecological risks from multiple stressors is becoming increasingly important as our environmental and regulatory focus moves from managing point sources to one of managing and trading risks from multiples sources over large geographic areas. There are important corollaries to this shift in focus and scale, one is the increased

Mechanisms of pyrethroid neurotoxicity: implications for cumulative risk assessment

Toxicology, 2002
The Food Quality Protection Act (FQPA) of 1996 requires the United States Environmental Protection Agency to consider the cumulative effects of exposure to pesticides having a 'common mechanism of toxicity.' This paper reviews the information available on the acute neurotoxicity and mechanisms of toxic action of pyrethroid insecticides in mammals from ...

Anatomy of Risk: Cumulative Disadvantage and Risk Assessment Instruments

2018
One significant critique of the United States criminal justice system is the disproportionate rate at which people of color and people living in poverty are represented. Proponents of the use of risk assessment instruments in criminal justice system decision-making claim the tools are likely to reduce the effects of implicit biases and stereotypes in ...

Generation of hazard indices for cumulative exposure to phthalates for use in cumulative risk assessment

Regulatory Toxicology and Pharmacology, 2014
Exposures to multiple chemicals may contribute to increased risk of similar adverse effects. Cumulative risk may be estimated using a hazard index (HI), the sum of individual hazard quotients (HQ, ratio of exposure to the reference value). We demonstrate the HI approach for five phthalates: di(2-ethylhexyl) phthalate (DEHP), di-n-butyl phthalate (DBP),

Multi-Pathway and Cumulative Risk Assessment

2001
Most pollution control strategies can be characterized as a single -medium, single pollutant, approach. Such an approach begins by dividing the environment into three primary compartments: air, water, and land (soil). Pollution problems then are grouped into three categories: air pollution, water pollution, and solid waste pollution problems.

Comprehensive Assessment of Risk to Ecosystems (CARE): A cumulative ecosystem risk assessment tool

Fisheries Research, 2017
Abstract Unassessed marine ecosystems are often unmanaged marine ecosystems. Several risk assessment methods exist that can provide a scientific basis for siting interventions and guiding management actions, but these methods focus mainly on single species and evaluate only the impacts of fishing in detail.
