2.3.3 Effects of heavy metals on plants Plants are sensitive for both‚ deficient and excess availability of some of the heavy metal ions. In which some of them at low concentration are compulsory micronutrients‚ while the same at higher concentrations such as Cd‚ Hg‚ As are intensely toxic to the metabolic activities of the plants (Reeves and Baker‚ 2000; Fernandes and Henriques‚ 1991).

rhizobacteria isolated from heavy metal contaminated soils INTRODUCTION As a result of human activities such as mining‚ agriculture and industrial activity‚ heavy metal pollution has become one of the most serious environmental problems today. Elevated levels of heavy metals not only decrease soil microbial activity and crop production‚ but also threaten human health through the food chain. Soil microorganisms can degrade organic contaminants‚ while metals need immobilization or physical removal. Although
