Exposure analysis is the science that describes how an individual or population comes in contact with a contaminant, including quantification of the amount of contact across space and time. 'Exposure assessment' and 'exposure analysis' are often used as synonyms in many practical contexts. Risk is a function of exposure and hazard.
They have the ability to identify if an exposure has occurred, the route of exposure, the pathway of exposure, and the resulting effects of the exposure. The use of biomarkers in exposure studies is also referred to as biomonitoring. When dealing with exposure assessment, there are three types of biomarkers that can be useful, biomarkers of ...
Workplace exposure monitoring is the monitoring of substances in a workplace that are chemical or biological hazards. It is performed in the context of workplace exposure assessment and risk assessment .
Occupational exposure banding has emerged as a helpful supplementary exposure assessment tool. [25] When conducting a workplace hazard assessment, occupational hygienists may find it useful to start with occupational exposure banding to identify potential hazards and exposure ranges, before moving on to control banding.
As emphasized in Figure 1, strong interactions are needed between the hazard assessment, exposure assessment, and population assessment activities. [12] Exposure- and population-informed hazard assessment ensures that realistic information about actual workplace exposure compositions, concentrations, and conditions are factored into any ...
The exposure assessment involves evaluating relevant exposure routes (inhalation, ingestion, dermal, and/or injection), amount, duration, and frequency (i.e., dose), as well as whether exposure controls are in place and how protective they are. When data are not available, this will be a qualitative process.
Biomonitoring is performed in both environmental health, and in occupational safety and health as a means of exposure assessment and workplace health surveillance. The two best established environmental biomonitoring programs in representative samples of the general population are those of the United States and Germany, although population ...
Control banding is a qualitative or semi-quantitative risk assessment and management approach to promoting occupational health and safety.It is intended to minimize worker exposures to hazardous chemicals and other risk factors in the workplace and to help small businesses by providing an easy-to-understand, practical approach to controlling hazardous exposures at work.
