A Study of Physico-Chemical Characteristics of Lakes
Abstract
Present paper deals with A Study of Physico-Chemical Characteristics of Lakes parameters (district of Krishnagiri, Tamil Nadu). Monthly variations in physical and chemical parameters such as temperature, pH (6.7 to 8.9), dissolved oxygen (5.2-7.5 mg / L), total hardness (68 to 190 mg / L), chlorides (11 to 1030 mg / L), phosphate (0.30 to 2.86 mg / L) nitrate (0.88 to 10.40 mg / L) etc. All the parameters were beyond the permissible limits.
Water is one of the most important and abundant ecosystem compounds. For their survival and growth, all living organisms on earth need water. Earth is now the only planet with about 70% of wat er. But due Increased human population, industrialization, fertilizer use in agriculture and man-made activity is highly polluted with various harmful contaminants. Water pollution is measured by assessing water’s physiochemical parameters.
Physi co-chemical analysis is the prime consideration in assessing the quality of water for its best use, such as drinking, irrigation, fishing and industrial purposes, and is helpful in understanding complex processes, interaction between climatic and biological processes in water.
