03033 - Toxicology

Learning outcomes

The course provides an introduction in the field of Toxicology, the principles governing entry, fate and effects of toxicants on living systems, and the major genetic and environmental determinants of risk. Emphasis will be placed on xenobiotic effects on the metabolism and  the physiology of different cell types, tissues and organs systems. The course is concerned with general principles of risk assessment and the definition of limits of safety of chemical agents.
