Define exposure assessment.(Refer to Chapter 4: section 4.1; pg 42) [2]ï‚·Exposure assessment is the process of estimating or measuring themagnitude, frequency, and duration of exposure to an agent, along with thenumber and characteristics of the population exposed. Ideally, it describes thesources, pathways, routes, and the uncertainties in the assessment.ï‚·Exposure assessment is a comprehensive evaluation and analysis of thenature and extent of potential exposure to hazardous substances, physicalagents, or other stressors in a particular environment. It involves collectingand interpreting relevant data, such as measurements, observations, andestimates, to determine the level of exposure for individuals or populations.ï‚·The goal of exposure assessment is to identify and characterize potentialhealth risks associated with specific exposures, in order to inform thedevelopment and implementation of appropriate risk management strategiesand interventions. Due to the complexity and scale of the EHRA process, aconcise ‘cookbook’ or standardized approach to exposure assessment is notfeasible.ï‚·Although a concise cookbook approach on exposure assessment is notpracticable due to its complexity and scale, there are several approaches toexposure assessment that can be used. These include receptor-basedapproach, direct approach, indirect approach, and exposure factors.
