What Is A Toxicologist?

Toxicology is the study of the effects of chemical, biological, and physical agents on living organisms, particularly humans .

A toxicologist is a scientist or researcher who helps us better understand the possible harm that different substances, pollutants and microorganisms can cause on the human body, other living things, and the environment.

There are many different fields within toxicology, some of the common ones include:

Forensic — detection of drugs and toxins in bodily tissues and fluids in criminal investigations

Environmental — research of pollutants found in air, soil, and water related to public health

Medical — evaluation and treatment of healthcare patients exposed to poison or toxins

  • Basic Reading, Writing & Math

  • Computer Science

  • Biology

  • Chemistry

  • Physics Lisa Simpson conducting a science experiment

Undergraduate Programs

When you're ready to look for the right college, research schools with a program in toxicology. If one is not available or convenient to you, major in biology or chemistry. Along with courses in biology and chemistry, make sure to include courses in physics, computer science, statistics, and math (yes, even calculus).

Other Important Skills to Develop

Some additional skills that will help you include:

  • Strong written and oral communication

  • Laboratory practice

  • Project management

  • Computer knowledge

Graduate School And Beyond

If you're interested in taking your studies further, research prerequisites needed before applying to graduate and doctoral programs. You'll need advanced courses in chemistry and biology, as well as scientific writing and public speaking.

Summer internships are a great way to gain valuable work experiences, such as laboratory and research experience along with leadership skills that can give you an advantage when applying to programs. Moira from Schitt's Creek saying,
