This course depends on both basic and applied scientific knowledge to understand natural and anthropogenic (man-made) pollutants’ life cycle and their impact on structures and functions of biological and ecological systems. In this course, the effects of chemicals of environmental interest, environmental toxins, will be investigated at the level of molecules, cells, tissues, organs, organisms, populations, communities and ecosystems. The main questions to answer are: what are the sources of pollutants, how are we exposed to them; how pollutant causes harmful effects, how can we measure the extent of the effects, and what can we do to prevent or minimize the risk to biological and ecological systems?
The course is designed to be interactive; basic principles of toxicology are applied to environmental problems and case studies and special topics will be reviewed and discussed. This will include the chemodynamics of contaminants in the environment including fate and transport, risk assessment and management. The impacts of chemical contaminants and stressors upon ecosystems, acute and chronic effects of carious classes of chemical, biological, and physical agents (e.g., pesticides, drugs, metals, and industrial pollutants) on living organisms, description and prediction of ecological changes resulting from a variety of human activities which involve release of xenobiotic and other chemicals into the environment are also discussed. Actions to protect the environment and the health will also be reviewed.
