Última Arsenic phytoextraction and hyperaccumulation by fern species Scientia Agricola Gonzaga,Maria Isidoria Silva; Santos,Jorge Antonio Gonzaga; Ma,Lena Qiying. Arsenic (As) is an ubiquitous trace metalloid found in all environmental media. Its presence at elevated concentrations in soils derives from both anthropogenic and natural inputs. Arsenic is a toxic and carcinogenic element, which has caused severe environmental and health problem worldwide. Technologies currently available for the remediation of arsenic-contaminated sites are expensive, environmentally disruptive, and potentially hazardous to workers. Phytoextraction, a strategy of phytoremediation, uses plants to clean up contaminated soils and has been successfully applied to arsenic contaminated soils. It has the advantage of being cost-effective and environmentally friendly. A major step towards the development of phytoextraction of arsenic-impacted...

Plant Physiol. Gratão,Priscila Lupino; Prasad,Majeti Narasimha Vara; Cardoso,Patrícia Felippe; Lea,Peter John; Azevedo,Ricardo Antunes. The contamination of the environment by toxic metals poses a threat for "Man and biosphere", reducing agricultural productivity and damaging the health of the ecosystem. In developed nations, this problem is being addressed and solved to some extent by using "green technology" involving metal tolerant plants, to clean up the polluted soils. The use of naturally occurring metal tolerant plants and the application of genetic manipulation, should hasten the process of transferring this technology from laboratory to field. Therefore, it is essential to investigate and understand how plants are able to tolerate toxic metals and to identify which metabolic pathways and genes are involved in such a process. Recent advances in knowledge derived from the "omics",... Tipo: Info:eu-repo/semantics/article Palavras-chave: Hyperaccumulator plants; Phytoremediation; Toxic metals.
