Abstract

Depending on the environmental conditions soil intra metal chemistry also differs especially mobility, solubility of metals also depends on the physicochemical parameters of the soil. It also depends on the saturation and unsaturation conditions of paddy soil. Each day ground water is being withdrawn for the irrigation of Boro. Groundwater is a significant natural source for domestic and industrial water supply as well as agricultural purposes. But the over exploitation of groundwater resources especially as contaminated groundwater is now the main concern to health safety and the sustainable agriculture. The natural occurrence of arsenic in groundwater establishes a major obstruction in the delivery of safe drinking water to millions of people in Asia and world- wide. This problem makes a wide range of complications in terms of water quality as well as quantity and it is emerged during the past three decades. Arsenic is by far one of the most toxic elements in the environment. From this experiment we conclude how various heavy metals concentration differ in different fraction of different experimental field and as well as the different part of the rice plant and their relationship with the various environmental conditions. Additionally, it describes several sources and the effects of As, Pb, and Mn on the environment, the advantages of this kind of technology for reducing them, and also heavy metal uptake mechanisms in phytoremediation technology as well as the factors affecting the uptake mechanisms. Some recommended plants which are commonly used in phytoremediation and their capability to reduce the contaminant are also reported.
