Phytoremediation of Arsenic-Contaminated Soils Using Arsenic Hyperaccumulating Ferns

摘要: Arsenic contamination of soils is a global environmental, agricultural, and health issue given to the toxic carcinogenic nature As. Several anthropogenic activities, such as mining smelting, coal combustion, wood preservation, leather tanning operations, use As-based pesticides in agriculture, have led elevated concentrations As soil. Therefore, remediation restoration As-contaminated imperative for providing safe food healthy soils. In contrast conventional (physicochemical) methods, phytoremediation using As-hyperaccumulating fern species has emerged an eco-friendly, cost-effective, efficient technology. Since discovery As-hyperaccumulator, Pteris vittata L., several other been identified Pityrogramma genera which demonstrated ability remove from This review will briefly discuss about dynamics availability soil; elucidate mechanisms involved tolerance (hyper)accumulation by ferns/plants improving efficiency; evaluate capacity (e.g., P. vittata, calomelanos) under pot field conditions; how phosphate amendments, microbes, agronomic practices can increase efficiency ferns.
