It includes the study of mode of action of poison, symptoms of poison and treatments associated with poisoning along with their detection in biological system. And the volatile substances can be separated from gaseous. And their evaluation involves identification and quantification of poisons using various analytical techniques. It deals with the evaluation of toxic substances present in biological specimen as well as in raw form or crude form. There are several branches of toxicology, known as subdisciplines or subspecialties, which focus on particular aspects of toxicology. Understanding The Process Of Detection and Classification. These are also CNS depressants. However, some terms are more general and used throughout the various sections. Most terms are very specific and will be defined as they appear in the tutorial.

Irritant gases, alkaline corrosives, corrosive … Some refer to toxicology as the “Science of Safety” because as a field it has evolved from a science focused on studying poisons and adverse effects of chemical exposures, to a science devoted to studying safety. The common poisons of this group are arsenic, lead, mercury, antimony, bismuth etc. It is a medico-legal aspect of clinical poisoning.
