Introduction to Environmental Toxicants
Environmental toxicants are agents in our surroundings that are harmful to human health. Some substances, such as air and water pollutants, are recognized for their toxicity. No one would knowingly breath air polluted with sulfuric acid or drink water containing pesticides. However, other toxic agents equally harmful to human health (food additives and contaminants, bacteriotoxins, fungitoxins, phytotoxins, household products, and industrial chemicals) often go unrecognized for their serious toxicity.
