The present study was undertaken on the effect of speciation of heavy metals on uptake, growth and biochemical changes on two wetland plants, viz. Scirpus littoralis and Paspalum distichum. In the first chapter a detailed introduction to the topic including its justification of study is included. The second chapter consists of the objectives of the study. The third chapter gives an elaborate literature review on heavy metal speciation, uptake of metals in plants, different strategic mechanisms of heavy metal accumulation in plants, toxicity and tolerance in plants. The fourth chapter...
