Environmental Monitoring Environmental monitoring involves the systematic collection of data on the presence and concentration of contaminants in various media. This can include air sampling, water testing, soil analysis, and biological monitoring. The collected data helps epidemiologists understand the distribution and levels of contaminants in the environment.
Exposure Assessment Exposure assessment is the process of estimating or measuring the magnitude, frequency, and duration of exposure to an environmental agent. This involves evaluating the routes of exposure (inhalation, ingestion, dermal contact) and identifying the populations at risk. Accurate exposure assessment is critical for determining the potential health impacts of environmental contaminants.
Risk Assessment Risk assessment involves evaluating the likelihood and severity of adverse health effects resulting from exposure to environmental hazards. This process includes hazard identification, dose-response assessment, exposure assessment, and risk characterization. Epidemiologists use risk assessment to inform public health policies and interventions aimed at reducing exposure and preventing disease.
