Toxicology is the study of the interactions between potentially harmful substances, living organisms and the environment. It is a wide-ranging subject that encompasses a number of biological and chemical disciplines including pharmacology, biochemistry, physiology, molecular biology, pathology and immunology.
Toxicology plays a vitally important part in our lives. It helps to ensure that the food we eat, the water we drink and the air we breathe are clean and free from contaminants and toxins and that the pharmaceutical drugs we take to treat disease are as safe as possible. Toxicology is important clinically in the diagnosis and management of poisonings and in the analysis of forensic samples.
Toxicology also has a central role in protecting the environment from the harmful effects of chemicals, pesticides and other noxious agents. Toxicology is a dynamic subject, which is expanding and adapting as society changes and new demands have to be met. It offers tremendous mental stimulation ranging from the application of state of the art molecular biology in the study of mechanisms of toxicity and carcinogenesis, to the integration of the science leading to risk and safety assessments. It is becoming increasingly important in determining our quality of life and that of future generations..
