Over the past few years, the field of toxicology has experienced remarkable expansion. Due to the proliferation of many toxic compounds that are industrial, medicinal, environmental, animal, and plant-based, significant advancements in this field are imperative. Therefore, the harmful effects of physical and chemical agents on all living systems have received particular attention in the field of toxicology. Because of its challenging diagnosis process, contentious management, and unclear end targets, toxicology can function as a separate descriptive and empirical field. Before the availability of confirming data, many fatal exposures should be diagnosed and treated as soon as possible. Students studying undergraduate laboratory technology who assist in treating poisoned patients will get inspiration mostly from these toxicology lecture notes. Nonetheless, it may be pertinent to other medical experts whose specialities deal with related issues. The book's outline format makes it possible to review important information in particular quickly.
