Abstract

Environmental exposure refers to contact with physical, chemical, or biological agents in the environment that may affect human health. Common exposures include air and water pollution, pesticides, radiation, industrial chemicals, and heavy metals. Increasing urbanization, industrialization, and climate change have intensified these exposures, posing risks such as respiratory diseases, cancer, neurological disorders, and reproductive harm. This article explores the types and sources of environmental exposures, their health consequences, vulnerable populations, and strategies for mitigation. Emphasis is placed on the importance of policy enforcement, public awareness, and individual action in reducing exposure risks and improving health outcomes.
