Monitoring of coastal water quality is done on regular basis in most oceanic countries since it plays an important role in detection and evaluation of marine water pollution. The book deals with an exhaustive account of present status of marine environment and sources, types & effects of marine pollutants on water and marine organisms. Standard Methods for physical (Colour, Odour, Temperature, Turbidity, Total Solids, Total Dissolved Solids, Total Suspended Solids, Conductivity), chemical (pH, Dissolved Oxygen, Biochemical Oxygen Demand, Carbon dioxide, Chemical Oxygen Demand, Salinity, Alkalinity, Orthophosphate, Ammonia, Nitrite, Nitrate, Silicates), microbiological (Presumptive test, Confirmed test, Completed test, Gram staining, Motility test, IMViC tests) and biological (Chlorophyll a, Macrobenthos: Population density, Biomass, Diversity Indices) assessment of coastal water were described along with methods of Water Sampling (Traditional & Recent Approaches) and Soil TextureAnalysis. Data presented in the book should be useful to undergraduate, postgraduate and research students of Botany, Zoology, Microbiology & Environmental Sciences.
