Environmental assessment of marine and estuarine waters along the coast of thoothukudi city

Abstract

The coastal region plays a major role in producing the resources dynamically. The coastal pollution is due to the untreated industrial and domestic waste discharge, activities of harbor rummaging, spilling of shipping cargos, other fishing activities. The studies of marine pollution will effects on the chemical, biological and physical parameters in the surrounding areas. The effect or damage of certain parameters in the marine area is studied. This pollutions will affect the marine ecosystem and the creatures present there. This study is about the investigation of the marine and estuarine waters along the coast of Thoothukudi city. The Physico-chemical parameters are analyzed from the samples collected in 32 sites of the Thuthookoodi coastal area. All the physical parameters like pH, salinity, DO, Conductivity, Turbidity and TDS and chemical parameters like Arsenic (AS), Cadmium (Cd), Cobalt (Co), Chromium (Cr), Lead (Pb), Molybdenum (Mo), Silicon (Si) are been analyzed. Most of the samples the silicates are been measured in the waters collected at the coastal site. Thoothukudi coastal water is exposed to seasonal variations in physico-chemical characteristics relied upon the seasonal tidal fullness and estuarine incursion influencing in continuous mixing of fresh and salt water at the Thutookoodi coastal areas. These changes in the parameters affected the climate shift, and altered in the temperature effects on regional and global scales. It has already challenging and complicated the situation. From the last few years it became clear that reactions can be more efficient achieved using a standard method of controlling pollutions like oil spillage, industrial sludge etc.
