title: Heavy metals concentrations in the sediments from Kolleru Lake, India.
abstract: Kolleru Lake is the largest natural freshwater lake of Andhra Pradesh in India. It is situated between the latitudes 16 degrees 32(1) and 16 degrees 47(1)N and longitude 81 degrees 05(1) and 81 degrees 21(1) E. The catchment area of the lake is 4763 sq. km. The sediment samples were collected at different points from Kolleru Lake in three seasons a year over a period of three years and analyzed for heavy metals and organic matter. Concentrations of Cu, Pd, Cd, Mn, Ni, Co, Fe and Zn in the sediments were analysed by using Atomic absorption spectrometer (AAS) and selected sediments samples were analysed for Be, Sr, Ba, B, Mo, Tl, V, Cr, Ag, Bi, As and Se by using inductively coupled plasma Mass Spectrometer (ICP-MS).
