SYLLABUS • •

Introduction to environmental sciences - impact of environment on quality of life The atmosphere – green house gases and global climate – stratospheric ozone depletion – emissions to atmosphere and air quality – particles and acid deposition – acid rain; The oceans – sea water composition – suspended particles and marine sediments – marine contaminants and pollution; Fresh waters – aquatic chemistry – weathering processes – complexation reactions – species distributions – case studies ; toxic metals in water – water treatment; Land contamination and reclamation - sources of land contaminants – characteristics of major land contaminants – possible hazards – site investigation – reclamation methods – case studies; Environmental cycling of pollutants – biogeochemical cycling – environmental reservoirs – lifetimes – environmental partitioning – case studies; Environmental monitoring – objectives – different types of monitoring – sampling methods – modeling of environmental dispersion – duration and extent of survey - monitoring protocol – remote sensing of pollutants – data presentation; Ecological and health effects of chemical pollution – toxicity – exposure – absorption – role of biomarkers – health effects of major pollutants; Environmental quality management – standards and limits – legislation to control and prevent pollution – pollution control agencies – public and commercial pressures to improve environment – concept of sustainable development.
