Toxicologists plan and carry out laboratory and field studies using the most modern molecular, genetic, and analytical techniques available to evaluate and monitor the impact of toxin and chemicals on human and animal health. They are also concerned with the impact of toxins and chemicals on the environment and the impact future technology may have.
Toxicologists help ensure the food we eat and the water we drink is clean and safe for consumption, that the air is pollutant-free and that the drugs we take for medical purposes are as safe as possible.
Toxicologists may also help doctors diagnose patients who have been exposed to certain chemicals. Depending on the type of work a toxicologist performs, he or she may be employed in a hospital laboratory, university, government agency, or a private research organization.
