摘要: Abstract In nature, the overall effect of heavy metals on biota can be influenced by a number ofenvironmental factors like soil characteristics and air pollution elevated CO 2 .Pillbugs (Isopoda, Armadillium vulgare ) take up with their food store themmainly in vesicles hepatopancreas. They accumulate certain metals, occur relativelylarge numbers, are easily collected identified, provide sufficient material for analysis.The species decomposing litter well impurities into N P. Therefore, it has beensuggested that total body concentration pillbugs could positively correlated tothe levels environmental exposure used as biological indicators ofmetal global change . The aim study is to determine effects heavymetal concentrations pillbugs’ accumulation metaland growth rate.In this study, six (Fe, Mg Cu, Zn, Pb, Cd) have been determined.Pillbugs (N=287) were at five sites during Jul-Aug, 2006. Cu Zn inthe much higher than soils(1.39-41.70 times). This indicated thatbioaccumulation some increasing food-chain. highbioconcentration lead Sangam may partly associated reclaimed land uses.Keywords : soil, pillbugs, reclamation sites, bioaccumulation
