Solvents and Vapours Toxicology

Solvents and vapours represent a major class of occupational and environmental toxicants with significant systemic health effects. This topic covers the definition, classification, absorption, distribution, and toxic mechanisms of solvents such as aliphatic hydrocarbons, halogenated hydrocarbons, aromatic hydrocarbons (e.g., benzene, toluene), alcohols, and glycol ethers. Zambian college and university students in occupational health, industrial hygiene, and biomedical sciences will learn about the CNS depressant effects, hepatorenal toxicity, carcinogenicity, and reproductive hazards associated with solvent exposure. Understanding exposure assessment, susceptible populations, and regulatory limits is crucial for safeguarding worker health in Zambia's industrial and artisanal sectors. This topic is foundational for examination success and for developing effective workplace safety protocols.
