Recent advances in phytoremediation of arsenic-contaminated soils
Arsenic contamination in soils occurs widely in a range of ecosystems resulting from geological origins and anthropogenic activities. On average, arsenic concentration ranges from 5 to 10 mg kg−1 in uncontaminated soils and above 10 mg kg−1 in contaminated soils (Hossain, 2006). Increased buildup of arsenic in irrigated soils has been widely recognized in South and South-east Asia (Brammer and ...
متن کاملPhytoremediation of arsenic-contaminated groundwater by the arsenic hyperaccumulating fern Pteris vittata L.
Arsenic concentrations in a much larger fraction of U.S. groundwater sources will exceed the maximum contaminant limit when the new 10 microg L(-1) EPA standard for drinking water takes effect in 2006. Thus, it is important to develop remediation technologies that can meet this new standard. Phytoremediation of arsenic-contaminated groundwater is a relatively new idea. In this research, an arse...
متن کاملPhytoremediation of arsenic contaminated paddy soils with Pteris vittata markedly reduces arsenic uptake by rice.
Arsenic (As) accumulation in food crops such as rice is of major concern. To investigate whether phytoremediation can reduce As uptake by rice, the As hyperaccumulator Pteris vittata was grown in five contaminated paddy soils in a pot experiment. Over a 9-month period P. vittata removed 3.5-11.4% of the total soil As, and decreased phosphate-extractable As and soil pore water As by 11-38% and 1...
متن کاملAssessing Plants for Phytoremediation of Arsenic-Contaminated Soils
Arsenic (As) is a pollutant of major concern throughout the world, and causes serious environmental problems in many areas including, for example, West Bengal, Bangladesh, and Vietnam. Phytoremediation is potentially a cost-effective and environmentally benign method of extracting pollutants from soils for which there have been significant recent advances for As. In particular, the discovery of...
