Crop grown on metal contaminated soils accumulate heavy metals in quantities, excessive enough to cause clinical problems. The samples were brought to laboratory and few drops of HNO added to minimize the microbial activities and avoid precipitation of some heavy metals. The instrument is flushed with rinse solution between samples and standards during the analytical run. contaminant levels (MCL) for various metal ions in drinking water (Table 1 - Page 2). 1.1.2 Water and Heavy metals:- Water covers about 71% of the earth surface but available fresh drinking water is only 3% out of which 69% is trapped as ice in two Polar Regions. The factors that influence the content of heavy metals in plants also include individual properties of 8.13. This requires that public water supplies be monitored for these metals regularly. The analysis also showed that the quality of water remains mostly unchanged in terms of chemical and biological (micro-organisms) aspects. Ismail and Mat Saleh (2012) [19] have analyzed different heavy metals in wa- ter samples from Malysia and results showed that the concentrations of heavy metals in water samples were below the detection limit. The heavy metals such as lead, iron, cadmium, arsenic, copper, zinc, chromium etc in drinking water causes human disease condition. Metals in water and wastewater may be present in any or all of the following forms, each of which may require determination: (a) Dissolved (filterable) metals: Those metals which pass through a 0,45 ym membrane filter. The study investigated the most common heavy metals Pb, Cd, Ni, and Cr indicating higher concentrations of heavy metals in blood and feathers from the study site. Compared to sediments, marine organisms exhibit greater spatial The other two are: Water quality monitoring program design: A guideline to the development of surface water quality monitoring programs But high doses are toxic, in part because metals bond to sulfur groups, interrupting cellular activity and contributing to oxidative damage. Contamination of soil by heavy metals was investigated in [5], [6] and [7]. samples.The Heavy metal concentration, in water was in the order Pb > Cr > Cd > Ni , in sediments Pb > Cr > Cd > Ni .

Therefore, it is important that a study is conducted in order to determine the contaminants in river water by heavy metals. Contamination along a motorway was investigated in [5], in an industrial zone in Iran in [7], while an investigation along a highway in Slovenia is shown in [6]. This study was carried out to examine heavy metals concentration in water and sediment of upstream and downstream of the entry of the sewage to the Tembi River, Iran. the factors impeding access to safe water is water pollution. The rate of bioaccumulation of heavy metals in aquatic organisms depends on the ability of the organisms to digest the metals and the concentration of such metal in the water body. water and distilled water were used for all preparation and dilution purposes throughout the study. Volume 2, . Analysis of Heavy metals in Water, Sediments and Fish samples of Madivala Lakes of Bangalore, Karnataka. The levels of heavy metals in Oysters and other invertebrates are often considerably higher than in other constituents of the marine environment. The main source of contamination of oils with heavy metals is their direct migration from arable land to oil plants. Limits on heavy metals in waste water and drinking water are often stated in parts per billion (ppb) and are heading in only one direction: down. Wastewater . 1.1 EFFECTS OF HEAVY METALS IN WATER Below a certain threshold many heavy metals and transition metals are essential for human health (Hanikenne, 2009). (2005 . in o-o- re.
