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 ...

Cumulative risk assessment of pesticide residues in food

Toxicology Letters, 2008
There is increasing need to address the potential risks of combined exposures to multiple residues from pesticides in the diet. The available evidence suggests that the main concern is from dose addition of those compounds that act by the same mode of action.

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 ...

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 ...

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.

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
