ABSTRACT

Inductively Coupled Plasma – Optical Emission Spectrometer (ICPOES) is one of the widely using technique for determination of multielements in various environmental, food and drug matrices. In the present study 35 ground water samples are collected in selected villages of coastal area of SPSR Nellore district in which the public are using ground water for drinking purpose. The present study includes the analysis of 14 metal concentrations like Beryllium (Be), Boron (B), Aluminium (Al), Antimony (Sb), Manganese (Mn), Molybdenum (Mo), Iron (Fe), Copper (Cu), Zinc (Zn), Indium (In), Tin (Sn), Barium (Ba), Thallium (Tl) and Silver (Ag) by using (ICP-OES) in the selected samples. The test results of 14 metals are summarized, discussed compared with drinking water quality standards given by the Indian Standards (IS : 10500) and World Health Organization (WHO), 4th edition in 2011.
