What is Toxicology?

Toxicology combines the elements of biology and chemistry with many other disciplines to help us understand the effects of chemicals on living organisms.

Toxicologists:

  • Develop new and better ways to determine the potential harmful effects of chemical and physical agents and the amount that will cause such effects. An essential part of this is to develop an understanding of the basic molecular, biochemical and cellular processes responsible for diseases caused by exposure to chemical or physical substances.
  • Design and carry out carefully controlled studies of specific chemicals of social and economic importance to determine the conditions under which they can be used safely (i.e.; have little or no impact on human health or the environment).
  • Assess the probability, or likelihood, that particular chemicals, processes or situations present a significant risk to human health and/or the environment, and assist in the establishment of rules and regulations aimed at protecting and preserving human health and the environment.
