Human environmental safety is a multidisciplinary topic concerned with assessing and managing risks to human health arising from environmental exposures to chemical, physical, and biological agents. It encompasses hazard identification, dose–response assessment, exposure assessment, and risk characterization, integrating toxicology, epidemiology, environmental chemistry, and exposure science. The field informs regulatory thresholds, safety factors, and environmental quality standards aimed at preventing adverse outcomes such as carcinogenicity, reproductive toxicity, neurotoxicity, and respiratory disorders. Human environmental safety also includes evaluation of cumulative and aggregate exposures, susceptible populations, and uncertainty analysis to guide risk management, sustainable chemical use, and environmental health policy.
