the study of the effects of chemicals that are harmful or fatal when exposed to organisms
the study of the harmful effects of substances on the body, including the level of toxicity, the mechanism by which toxicity occurs and how it can be controlled
The science that deals with poisons and their effects on plant, animal and human life
Division of medical and biological science concerned with drugs Scientists study their chemistry and pharmacological actions, and establish antidotes and treatment of toxic manifestations, prevention of poisoning, and methods for controlling exposure to harmful substances
The multidisciplinary science that examines the adverse effects of chemicals on organisms
Toxicology is the study of poisons. + toxicological toxi·co·logi·cal There were no adverse toxicological effects. + toxicologist toxicologists toxi·colo·gist Toxicologists attempt to identify and understand toxic hazards. the science and medical study of poisons and their effects. Study of poisons and their effects, particularly on living systems. It overlaps with biochemistry, histology, pharmacology, pathology, and other fields. Its functions have expanded from identifying poisons and searching for treatments to include forensic toxicology (see forensic medicine) and testing and detection of a fast-growing number of new potentially toxic substances used in workplaces, in agriculture (e.g., insecticides, other pesticides, fertilizers), in cosmetics, as food additives, and as drugs (see drug poisoning). Perhaps the area of largest expansion is the study of toxic waste in the air, water, and soil, including chlorofluorocarbons, acid rain, dioxin, and radioactive isotopes
The science of the harmful effects of chemicals (including drugs) on living biological systems It seeks to determine the mechanisms by which chemicals produce adverse effects in cells and organisms
The science of poisons; that department of medical science which treats poisons, their effect, their recognition, their antidotes, and generally of the diagnosis and therapeutics of poisoning
study of poisonous substances in terms of their chemistry, effects, and treatments
Study of the nature, effects, and detection of poisons in living organisms Also, substances that are otherwise harmless but prove toxic under particular conditions
