ABSTRACT

Intensive development of industry transport and technology has contributed to the rise in heavy metal content in the soils and crops to a level hazardous to population inhabiting the affected regions, contaminated soils and waters pose major environmental and human health problems. Heavy metals are non biodegradable and therefore accumulate in the environment and subsequently find their way into the food chain. Therefore, effective remediation of heavy metal pollution is a top priority. Phytoremediation of soil has attracted much attention in recent years due to its multiple advantages such as maintaining the biological activity and physical structure of soils, being potentially inexpensive and visually unobtrusive, and providing the possibility of biorecovery of metals. Concentrations of metals were determined both in the soil and the plants grow in the mine area. The aim of the research to detect and define the type of plants species and there various parts which show maximum accumulation can be employed in the biomonitoring and phytoremediation study. It has been observed that the accumulation of Sr in Tridax procumbence was found to be 6.38 mg/L (shoot) and 0.92 mg/L (Root) where as in rhizosphere soil it is 2.22 mg/L. The factors affecting metal accumulation by plant species, including metal concentration, pH, EC, organic matter, phosphate and nitrate nitrogen and available nitrogen were measured

Keywords: Phytoremediation, heavy metals, soils, accumulation.
