Strength: The main strength of assessment of epidemiology on human health from exposure to chemicals is that the assessment covers all aspects of epidemiology from chemicals of environment i.e. oil, water, air, and food. This also covers all routes of entry of food i.e. inhalation, ingestion, and dermal absorption. That’s why this assessment contributes majorly in assessing the possible impact of toxic agents on potentially exposed populations. By help of such assessment, it facilitates to identify the concerning principal medium or microenvironment of the chemical exposure. Weakness: The main weakness of epidemiology on assessment of human health from exposure to chemicals is that assessment in epidemiology is generally hypothesis-based research. These studies are subject to further study or examine under specific populations or communities; thus they can elucidate the relation between health and chemical exposure. Otherwise effect of any exposure is not identified properly due to lack of dose-response relationship. By assessing human health from exposure through hypothesis-based research, the exposure assessment gets differed in site remediation, mitigation, and control and risk assessment.
