Exposure Assessment: Input into Risk Assessment

Archives of Environmental Health: An International Journal, 1988
The validity of a risk assessment can be no better than that of the exposure assessment upon which it is based. The general paucity of relevant exposure data, combined with the limited appreciation by most risk assessors of the critical dimensions and metrics of exposure, often leads to an overreliance on exposure models of questionable validity.

Pesticide exposure assessment

Toxicology Letters, 1995
Unintended, accidental, or unavoidable human exposures may result from pesticide use. Risk Characterization provides registrants, regulators, and the public a means to assess relative risks of pesticide use. Exposure Assessments are less standardized.

Exposure Assessment for Epidemiology: Characteristics of Exposure

Applied Occupational and Environmental Hygiene, 1991
Abstract Estimation of past exposures to potential health hazards is one of the most difficult problems for industrial hygiene research. Although it is very difficult, it is not impossible. There are two conceptual models that can guide the hygienist in this task: the source-receptor model and the task-TWA (time-weighted average) model of full-shift ...

Allergens Exposure Assessment

2006
Many allergens are widely used in both environmental and occupational products. In many cases, it is difficult to know all the ingredients of a product since most products are not sufficiently labelled. To diagnose and prevent allergic contact dermatitis, the demonstration of allergens in the products from the patient´s environment is important ...

Exposure Assessment

2017
Workers have the highest chance of being exposed to engineered nanomaterials; therefore, if such materials display hazardous effects, workers might develop adverse health effects upon exposure. In the absence of definitive information about the possible biological risk posed by nanomaterials, evaluation of exposure and implementation of measures ...

Assessment of Human Exposure to ENMs

2017
Human exposure assessment of engineered nanomaterials (ENMs) is hampered, among other factors, by the difficulty to differentiate ENM from other nanomaterials (incidental to processes or naturally occurring) and the lack of a single metric that can be used for health risk assessment.

Exposure Assessment

1999
Publisher Summary Assessment of exposures to air pollutants refers to the analysis of various processes that lead to human contact with pollutants after release into the environment. The routes of exposure to air pollutants include not only inhalation, but also ingestion, and dermal contact with pollutants that have been deposited or settled on soil ...

Chemical Spill Exposure Assessment

Risk Analysis, 1986
POSSM, the PCB On‐Site Spill Model, is a contaminant transport model developed to predict environmental concentrations associated with a chemical spill. The model predicts daily changes in chemical concentrations on a spill site (e.g., in soil and on vegetation) and losses of chemical due to volatilization, surface runoff/soil erosion, and leaching to ...

Validation of Benzene Exposure Assessment

Annals of the New York Academy of Sciences, 1997
We conducted a methodologic study to validate a quantitative retrospective exposure assessment method used in a follow-up study of workers exposed to benzene. Assessment of exposure to benzene was carried out in 672 factories in 12 cities in China. Historical exposure data were collected for 3179 unique job titles.

Assessing Hazard Exposure

2014
Disasters occur when physical and social systems interact with natural or technological hazards. The characteristics of the hazard itself are typically the most significant determinants of damage and loss. For example, in our work in Galveston, the exposure to storm surge (proximity to the bay side of the island) was the most important predictor of ...
