Environmental Contaminants

Environmental contaminants are substances, including chemicals, metals, and other materials, that can harm humans, animals, and the environment when they are present in air, soil, or water at levels higher than those known to be safe. Contaminants can come from many sources, including natural processes, agricultural activities, industrial activities, and other human activities. Once released into the environment, contaminants can move through soil, water, and air, and can be absorbed by plants, animals, and humans, causing health problems and environmental damage. Monitoring and reducing emissions of contaminants is essential for protecting public health and the environment.
