Toxicologists study the harmful effects of chemical, physical and biological agents on living organisms by detecting and examining the symptoms, mechanisms and treatments of poisoning (especially the poisoning of people). They also determine safe or acceptable levels of exposure to particular agents.
To become a toxicologist you usually have to complete a relevant science or forensics degree at university with a major in toxicology. To get into these courses you usually need to gain your Senior Secondary Certificate of Education. Prerequisite subjects, or assumed knowledge, in one or more of English, mathematics, chemistry, biology and physics are normally required. A number of universities in Australia offer relevant degrees. Universities have different prerequisites and some have flexible entry requirements or offer external study. Contact the institutions you are interested in for more information. For full details, refer to the entries on the website at www.goodcareersguide.com.au or university handbooks.
Toxicologists may perform the following tasks:
Toxicologists are employed across several industries, including pharmaceutical, food and chemical industries, environmental management, scientific research, government regulatory agencies, and other research organisations and health services. They are also employed in hospitals and educational institutions.
An analytical toxicologist identifies and measures toxic agents in biological and environmental samples to determine the extent of exposure (after poisoning or a chemical spill, or during long-term environmental contamination, for example) and to monitor the remediation of chemical spills.
A clinical toxicologist has medical qualifications to study the harmful effects of chemicals, drugs, pesticides and other substances on humans through the clinical diagnosis of symptoms and biological poisoning. Clinical toxicologists also treat and manage intoxicated patients.
An environmental toxicologist/ecotoxicologist studies the harmful effects of environmental exposure to chemical, physical and biological agents on living organisms (including their effects on humans, fish, other animals and plants), as well as their effects on ecosystems.
A forensic toxicologist specialises in the study of alcohol, legal and illicit drugs, and poisons, including their chemical composition, preparation and identification. Forensic toxicologists also study the absorption, distribution and elimination characteristics of chemicals and substances in the body, as well as the way in which the body responds to them and the factors that determine drug safety and effectiveness.
An occupational toxicologist studies the harmful effects of substances used in the workplace to determine a safe or acceptable level of exposure to workers, as well as appropriate control measures to reduce or eliminate worker exposure.
A regulatory toxicologist has the primary role of ensuring public health and safety from the use of chemicals, drugs and pesticides by identifying potential health risks posed by exposure to such substances. Regulatory toxicologists provide advice to governments, health professionals, politicians and the public on potential risks associated with chemical exposure so that appropriate risk management strategies may be implemented to protect the health of workers and the public.
