Abstract :

Water Quality is one of the most important concern of the world. Ground water is one of the major drinking water sources in throughout the world. Owing the mineralogical background of the area there might be chances to have higher concentration levels of some of dissolved heavy metals in ground water. By ingestion of ground water as a drinking water with excess concentration levels of dissolved heavy metals may cause various short term and long term health effects to the human being. Determination of heavy metals up to trace levels with high accuracy and precision is one of the most important concern of the analytical methodology. Number of techniques (like ICP–MS, ICP–OES, AAS, Cyclic Voltammetery and UV–Visible Spectrophotometer) is employed for the determination of heavy metals in water. Inductively Coupled Plasma– Mass Spectrometer (ICP–MS) is one of the most sensitive and universally using techniques for determination of heavy metal up to trace levels. In this present study an attempt has been made to know the concentration of eight heavy metals in ground water of Coastal areas of SPSR Nellore District, Andhra Pradesh. For this study 35 villages are selected in coastal areas of SPSR Nellore district and ground water samples are collected in the selected villages in which the public are using for drinking purpose and subjected to analysis for eight heavy metals like Arsenic (As), Nickel (Ni), Chromium (Cr), Lead (Pb), Cobalt (Co), Selenium (Se), Mercury (Hg) and Cadmium (Cd) by using (ICP–MS). The minimum and maximum concentration levels of these eight heavy metals are summarized and discussed in the results and discussion and the concentrations of these eight heavy metal levels in the study area were compared with drinking water quality standards given by the Indian Standards (IS : 10500) and World Health Organization (WHO), 4th edition in 2011
