Toxic Agents by TK - BMS Year 3 - Biomedical Sciences-unza

Description

These comprehensive third-year university notes cover the classification, mechanisms, and effects of major toxic agents encountered in environmental and occupational health. The material details the distinctions between toxicants and toxins, and systematically classifies poisons by target organ, source, chemical composition, and exposure routes such as air, water, and soil. It provides an in-depth analysis of air pollutants, including gaseous and particulate matter, ozone, CFCs, and their environmental impacts on vegetation, animals, and structures. The document extensively reviews toxic metals like lead, mercury, cadmium, chromium, and arsenic, explaining their common toxic mechanisms, specific organ toxicity (nervous system, kidney, respiratory, reproductive), and associated diseases such as Minamata disease and Itai-Itai disease. It also covers water and soil pollutants, including agrochemicals and fertilizers, and concludes with an overview of chelating agents used in treatment. This tertiary-level resource is essential for Biomedical Sciences students and lecturers at institutions like the University of Zambia, providing authoritative revision material for exam preparation and a deeper understanding of toxicology principles relevant to professional programmes.
