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.

Conclusion

A Lakes Temperature and photoperiod are important factors that control organisms ‘ behaviour, physiology, and distribution. The atmospheric and water temperatures ranged from 24.8 to 40.7 o C and from 14.0 to 34.1 o C respectively during the present study. Water temperature was the highest at Jalmahal and the lowest at Ramgarh Lake for the entire study period, similar to an earlier report (Srivastava et al., 2003).
