PAPER II: ENVIRONMENTAL GEOCHEMISTRY
UNIT I: Principles of environmental geochemistry, the distribution of elements in rocks and some geochemical associations, re-distributions of chemical elements by weathering. Soils and plants and the geochemical environment, soil plant relationship, soil-plant-animal relationship. Geochemistry applied to agriculture, sources of trace elements in soils, trace element problems in crops and livestock. Assessment of metal pollution in soils, sources and types of metal pollution, assessment of metal pollution.
UNIT II: Geochemistry and water quality, measures of water quality, chemical analysis, graphic representation, physical analysis, biological analysis. Water quality criteria, factors influencing groundwater quality. Pollution of groundwater. Assessment of metal pollution in rivers and estuaries.
UNIT III: Geochemistry and man, health and disease, essential elements, toxic and other elements, special problems of health and environment, trace elements and diseases, natural trace element poisoning, health implications of coal development.
UNIT IV: Heavy metal contamination from base metal mining and smelting, implication for man and environment, metal mining and human health. Radioactivity in the environment, radioactive elements in rocks, radioelements in soils and water, environmental aspects of radionuclides. Environmental pollution on global nature, acid rain, green house effect, ozone layer, CFCs, atmospheric pollution, sampling and analysis. Industrial pollution
