Seasonal Variations of the Sulur Pond at Coimbatore, Tamilnadu, India

Studies on the physico-chemical characteristics of the Sulur pond were carried out for a period of one year from October 2001 to September 2002). The study was performed to determine the pollution status of the pond and to implement the measures for pollution control. The parameters analysed include the physical parameters such as temperature, total solids, light penetration and electrical conductivity. The chemical parameters evaluated were pH, dissolved oxygen, carbon dioxide, carbonates, bicarbonates, chloride, organic carbon, BOD, and ions such as calcium, magnesium, nitrate, phosphate, silicate, iron, sulphate, sodium, lithium and potassium.
