A retain and refine approach to cumulative risk assessment

Food and Chemical Toxicology, 2020
Mixtures of substances to which humans are exposed may lead to cumulative exposure and health effects. To study their effects, it is first necessary to identify a cumulative assessment group (CAG) of substances for risk assessment or hazard testing. Excluding substances from consideration before there is sufficient evidence may underestimate the risk ...

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.

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 ...

The cumulative risk assessment of phthalates exposure in preterm neonates

International Journal of Hygiene and Environmental Health, 2023
Phthalates are widely used plasticizers in various consumer products and medical devices, with some reporting as having estrogenic and anti-androgenic endocrine-disrupting effects. Premature neonates may be exposed to high levels of specific phthalates during hospitalization in the neonatal intensive care unit (NICU) because of reliance on multiple ...

Cumulative risk assessment for quantitative response data

Environmetrics, 2003
AbstractThe Relative Potency Factor approach (RPF) is used to normalize and combine different toxic potencies among a group of chemicals selected for cumulative risk assessment. The RPF method assumes that the slopes of the dose–response functions are all equal; but this method depends on the choice of the index chemical, i.e. different index chemicals

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 ...

Is Epidemiology the Key to Cumulative Risk Assessment?

Risk Analysis, 2008
Although cumulative risk assessment by definition evaluates the joint effects of chemical and nonchemical stressors, studies to date have not considered both dimensions, in part because toxicological studies cannot capture many stressors of interest.

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.

The algorithm model for cumulative vulnerability risk assessment

International Journal of Internet Protocol Technology, 2014
The network information security vulnerability assessment consists of two kinds of risks. The stable risks of vulnerability itself and the cumulative multi-risks that are generated from a successful attack and which can impact on the whole network. To count cumulative multi-risk, a new method has been developed, which uses vulnerabilities in attack ...
