Nickel concentrations in groundwater depend on the soil use, pH, and depth of sampling. %PDF-1.2 As far as I know MoEF or CPCB has not given any permissible limits of heavy metal in soil unlike other countries like EU, USA etc. Soil samples were also collected from the site at 4 m depth for determining soil moisture content, bulk density, particle size distribution, atterberg limits, optimum moisture content and permeability (falling head). The effect of soil pH value on concentrations of Ni, Cu and Zn in ryegrass grown on two sludge-treated soils was examined under field conditions and the maximum permissible soil limit values for these elements were determined which prevent phytotoxicity in crops where sewage sludge is applied to agricultural soils with pH <6.0. Keywords: Soil quality, chemical parameters, Nagchoon pond, Khandwa. In the collected soil samples concentration concentration of nickel was recorded with in the permissible limit set by WHO. Optimum limit of each element is beneficial for plant growth as well as soil fertility. Nickel and copper concentrations are above acceptable limit and other metal concentration is within the acceptable limit. The average concentration of nickel was however, in the range of what was measured from studies in Abia (Okoronkwo et al., 2006) and Lagos state (Oyelola and Babatunde, 2008). Heavy metals (Cd, Zn, Cu, Cr, Pb and Ni) in the control samples were found to be 0.35, 40.00, 88.55, 0.65, 238 and 0.65 mg/kg for Cadmium, Zinc, Copper, Chromium, Lead and Nickel in plants respectively. In the collected soil samples concentration of nickel ranged between 0.150 to 1.031mg/kg. In all the collected plant samples, the concentration of arsenic was recorded in the range from 0.0107 to 0.2495 mg kg -1.

Acid rain increases the mobility of nickel in the soil and thus might increase nickel concentrations in groundwater (IPCS, 1991). • A need for a comprehensive monitoring of HM in soil in the European Union is proposed. The soil samples were between 0.066, 9.50, 4.83, 55.63, The average concentration in groundwater in the Netherlands ranges from 7.9 µg/L (urban areas) to 16.6 µg/L (rural areas). WHO Guidelines/Standards that dictates permissible limits of heavy metals in soils, particularly agricultural soil in this case. Thus, in Withania somnifera concentrations of Cadmium in root, leaf, stem and seed are within the permissible limit. Such standards were proposed for the five elements (mg/kg): copper – 3, nickel – 4, cobalt – 5, chromium – 6, zinc – 23. The maximum permissible limit for Ni in ground water is 0.2 mg/l recommended by WHO. The average concentration in groundwater in the Netherlands ranges from 7.9 µg/litre (urban areas) to 16.6 µg/litre (rural areas). Essential and nonessential heavy metals like iron (Fe), nickel (Ni), manganese (Mn), zinc (Zn), copper (Cu), cadmium (Cd), chromium (Cr), and lead (Pb) were analyzed in four selected medicinal plants such as Capparis spinosa, Peganum harmala, Rhazya stricta, and Tamarix articulataby flame atomic absorption spectrophotometer (FAAS). Comparing the obtained results with the permissible limit, arsenic was in values which correspond with literature data. Nickel in coals ranges up to 300 mg/kg; most /Filter /FlateDecode Ni concentrations in groundwater depend on the soil use, pH, and depth of sampling. The soil samples from Sinai site had the lowest level of Pb at 59.92 ± 8.42 ppm which was skewed towards the lower limit of normal range of Pb in soils. %PDF-1.5 EPA's Collaboration with the World Health Organization (WHO): According to EPA, the allowable limit of lead, copper and cadmium in drinking water is 0.015 mg/L, 1.3 mg/L, 0.005 mg/L. 12 0 obj ]-7�^��jyW(��.�Y��n��/��u߻�+;hW��@ ��鍝k�_A��7��f��d��0gk�>-�.�k��~��.��+]*��]9$}?
