Epidemiological studies: Research designs like cohort, case-control, and cross-sectional studies to investigate associations between exposures and health outcomes.
Field investigations: On-the-ground studies to identify the source and extent of health hazards.
Laboratory testing: Analyzing biological samples to detect pathogens, toxins, or genetic markers.
