Toxicologists design and conduct studies to determine the potential toxicity of substances to humans, plants, and animals. They provide information on the hazards of these substances to the federal government, private businesses, and the public. Toxicologists may suggest alternatives to using products that contain dangerous amounts of toxins, often by testifying at official hearings. There are an estimated 10,000 toxicologists currently employed in the United States.
