Introduction – Priority pollutants, exposure routes, toxicology and biomarkets, units for measurement, terminology and definitions. Aircomposition of atmosphere, particulate and gaseous pollutants – classification and standards, mechanical and thermal factors affecting pollutant transport – lapse rate, stability, wind speed; Atmospheric dispersion of pollutants; Local, regional and global transport of pollutants; Atmospheric Reactions – smog, ozone depletion and greenhouse effect, Sampling techniques. Water and Waste water – water and waste water quality definitions and characteristics – biological and chemical oxygen demand, turbidity, acidity, alkalinity, hardness, metal content, pathogenic content; water and waste water quality standards; Oxygen balance; Sampling Techniques. Soil – physical chacteristics – porosity, acidity, alkalinity, groundwater charging and groundwater pollution. Experimental methods for chemical and physical analysis – water quality analysis, organic and inorganic specialization and quantification – insitu sensors and laboratory equipment.
