Assessment of Heavy Metals in Water Samples of Certain Locations Situated Around Tumkur, Karnataka, India

Abstract

Surface water and groundwater samples of certain locations namely Kallambella, Bugudanahalli, Maidala, Honnudike, Kunigal, Kadaba and Hebbur, situated around Tumkur were assessed in the month of September 2008 for pH, EC and heavy metals Cd, Cu, Fe, Hg, Mn, Zn and Ni. The pH vales of surface waters were in alkaline range of 7.8-8.2 and are well within safe limits for crop production. The pH of groundwater was in the range of 7.6-8.4. The conductivity was in the range of 0.20-0.68 mS/cm and 0.34-2.44 mS/cm for surface and groundwaters respectively. High EC value of Kallambella groundwater accounts for its salinity. All surface waters except Honnudike and Hebbur samples contain low concentrations of these metals and are ideal for irrigation. Though the samples from Honnudike, Kadaba and Hebbur have high iron concentration, only Honnudike and Hebbur samples have exceeded the limit of 5 mg/L required for irrigation. In groundwaters the concentrations of all these heavy metals except copper are also well in permissible limits and suitable for drinking. Cu, Fe, Ni and Zn were detected in all the samples and found in the range of 0. 094-0.131, 0.958-12.537, 0.020-0.036 and 0.082-1.139 mg/L respectively in surface waters and these are in the range of 0.132-0.142, 0.125-1.014, 0.028-0.036 and 0.003-0.037 mg/L in ground-waters. The elements cadmium, mercury and manganese are absent in all the samples.

Chemical Profile of Drinking Water of Broiler Farms in Beheira Province

“…The recorded data in Table (1) declared that the mean value of Iron in the examined water samples was 0.2101 ± .055 mg/l that was within the maximum permissible limit determined by Watkins, (2008) for poultry water standards. The recorded result of iron detection was found in agreement with those recorded by Akoto et al, (2008), Bhaskar et al, (2010) and Tukura et al, (2014). The tabulated data in Tables (2) and (3) showed that the mean value of iron in examined ground water samples was higher than that of tap water samples with statistically significant difference.…”

Concentration and Health Implication of Heavy Metals in Drinking Water from Urban Areas of Tigray Region, Northern Ethiopia

“…The shortage of iron causes disease called "anemia'' and prolonged consumption of drinking water with high concentration of iron may lead to liver disease called as haermosiderosis (Rajappa et al, 2010;Bhaskar et al, 2010). In the areas studied, iron content varies from 97 μg/L Lead is the most significant of all the heavy metals because it is toxic, very common (Gregoriaadou et al, 2001) and harmful even in small amounts.…”

“…They produce 3,122 kilo litres of effluent per day. The Ranipet area is a chronic polluted area and one of the biggest exporting centres of tanned leather [8]. Ranipet is a medium-sized municipality located along Palar River bank in the Vellore District and 120 km from Chennai [11].…”
