ABSTRACT
An attempt was made during 2011-12 to determine the heavy metal status in Musi project command area in Nalgonda district, Andhra Pradesh. About 8 surface soil samples (0-15 cm), 22 water (surface and ground water), 5 plant and grain samples were collected during June, 2011 from a study area of 24,906 ha. The results of soil samples depicted that there is threat from pollution point of view with regard to heavy metals, especially Cd and Pb. In the water samples among the heavy elements Ni and Cd were found to be above the phytotoxic threshold levels. In rice grain and straw samples, but expect Cr, other heavy metals (Co, Ni, Cd and Pb) were found to be beyond the threshold levels.
Key words :
Heavy metal status, Micro nutrients, Musi command area, Phytotoxic limits, Rice crop, Water pollutants.
