Assessing 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...
متن کاملReduction and coordination of arsenic in Indian mustard.
The bioaccumulation of arsenic by plants may provide a means of removing this element from contaminated soils and waters. However, to optimize this process it is important to understand the biological mechanisms involved. Using a combination of techniques, including x-ray absorption spectroscopy, we have established the biochemical fate of arsenic taken up by Indian mustard (Brassica juncea). A...
متن کاملRecent 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 کاملIn Situ Remediation of Arsenic in Contaminated Soils
Owing to its toxic nature and relative abundance, arsenic is a common contaminant of concern in environmental cleanup. Arsenic is identified as a constituent of concern at 728 National Priorities List (NPL) sites as of fiscal year 1998, and arsenic in soil is specifically identified at 32 percent of these sites (Fiedler, 2001). Exposure to arsenic has been linked to a variety of cancers, cardio...
متن کاملBioaccessibility and Human Exposure Assessment of Cadmium and Arsenic in Pakchoi Genotypes Grown in Co-Contaminated Soils
In many countries cadmium (Cd) and arsenic (As) commonly coexist in soils contaminated by mining activities, and can easily enter the human body via consumption of leafy vegetables, like the popularly consumed pakchoi (Brassica chinensis L.), causing major health concerns. In the present study, bioaccessibility and human exposure of Cd and As were assessed in twenty genotypes of pakchoi culture...
