    Author: Udayakumar P, Chandran A, Jean Jose J, Rajesh BR, Narendra Babu K, Ouseph PP.
    Journal: Bull Environ Contam Toxicol; 2011 Dec; 87(6):662-8. PubMed ID: 21922283.
    Abstract:
    Spatial and temporal variations in concentration of dissolved metals viz. Copper (Cu), Lead (Pb), Chromium (Cr), Nickel (Ni), Zinc (Zn), Cadmium (Cd) and Mercury (Hg) in surface waters of southwest coast of India were studied. Concentrations of metals showed an aberration both temporally and spatially. Seasonal average concentrations of the analyzed metals followed the order Zn > Ni > Cu > Pb > Cd > Cr > Hg. The degree of contamination due to metal was determined by comparison with coastal water quality criteria. It established enrichment of Cu, Zn, Ni and Hg due to anthropogenic influence along southwest coast of India.
