Concept of Soil and Environmental Chemistry: Scope of Soil environmental Chemistry. Soil inorganic colloids importance. properties Matter and Cycles of matter: Endogenic and exogenic cycles. Pollution of the different spheres of the environment. Pollutants contaminants; Chemical fate and transport of different organic inorganic pollutants in the atmosphere, hydrosphere and geosph Distribution and transformation of different pollutants in environmental segments. Adsorption-filtration properties of soil i other environmental components. Organic Matter- Definition, types, components, sources fractionation; Humus - Chemical composition; classification properties; Importance of organic matter on soil and environmer properties and in relation to pollution. Liquid phase-Dynamic equilibrium of soil solution with solid gaseous phases of soil and atmosphere. Factors affecting composition and concentration of soil solution. Solubility movement of salts in lithosphere, hydrosphere and atmosphere: factors affecting salt movement. Importance of soil solution on! development and plant growth. Ion exchange reactions in soils; cation, anion and ligand exchan origin of ion exchange properties; Importance of ion exchange environmental remediation. Soil reaction- Active, exchange and potential acidities in soil. acidification- sources of hydrogen ion in soil and environment; $ alkalization sources of hydroxyl ion in soil and environme Importance of pH on soil properties and plant growth. Chemistry of soil amendments: Buffer components of soil and wa bodies and mechanism of buffering; amelioration of acidity alkalinity in soil and water; liming materials their reactions in soil; determination of lime requirement and factors controlling the liming program; Acid forming materials- sulphur and sulphate containing materials, their reactions in environment and factors controlling the acidification process.Organo-mineral associations - types and mechanisms of formation. Significance of organo-mineral associations on soil properties andenvironment.Water pollution and pollutants, Redox processes in aquatic environment; pE-pH diagram and relation; pE and free energy.
