Heavy metal distribution in sediments of Muthupettai mangroves, south east coast of India

, : Heavy metal distribution in sediments of Muthupettai mangroves, south east coast of India. Journal of Ocean University of China 10(4): 385-390

Core sediments from the Muthupettai mangroves on the southeast coast of India were analyzed for soil texture, total nitrogen, organic carbon, phosphorus and heavy metals (Fe, Mn, Cr, Cu, Ni, Pb, Zn and Cd). The distinct seasonal variation in the distribution of metals in the sediments was observed. The minimum concentration was recorded in river mouth and the maximum was in lagoon. High metal concentration in sediment was observed during monsoon and low concentration in summer. The total nutrient in lagoon and river mouth was recorded in the range of 4.528 to 8.526 mg g?1 for organic carbon, 2.213 to 1.5 mg g?1 for nitrogen and .824 to 7.22 mg g?1.
