Webb1 apr. 2024 · A few plants have shown the ability to remove organic compounds via phytovolatilization (Table 1). Brassica species, for instance, have been shown to remove selenium compounds such as dimethylselenide and dimethyldiselenide [ 27 ], as well as selenium and mercury [ 28 ] from water through phytovolatilization technique. Webb11 sep. 2003 · Plants remove Se by uptake and accumulation in their tissues and by volatilization into the atmosphere. During the process of Se phytovolatilization, plants metabolize various inorganic or organic species of Se (e.g. selenate, selenite, and Se-Met [Met]) into a gaseous form (Berken et al., 2002). tenjin yatai https://avanteseguros.com

Webb1 jan. 2015 · In upland ecosystems, plants may be used to accumulate Se in their harvestable biomass (phytoextraction). Plants can also convert and release Se in a volatile form (phytovolatilization). We discuss how genetic engineering has been used to develop plants with enhanced efficiencies for phytoextraction and phytovolatilization. WebbIn this process, contaminants are taken up by the plant and through transpiration, evaporate into the atmosphere. Apart from aerial Phytovolatilization, where volatilization occurs at the stem and leaves of the plant, root Phytovolatilization also occur, in which contaminants are volatilized from the root zone.

Webb10 juli 2024 · Overview. The term "phytotechnologies" broadly refers to the use of plants to address contamination in the environment, including soil, groundwater, surface water, sediment, and waste streams such as leachate, acid mine drainage, and wastewater (Pivetz, 2001) 1. Phytotechnologies are considered a green technology (ITRC, 2009; … WebbThe release of volatile contaminants to the atmosphere via plant transpiration, called phytovolatilization, is a form of phytotransformation. Although transfer of contaminants to the atmosphere may not achieve the goal of complete remediation, phytovolatilization may be desirable in that prolonged soil exposure and the risk of groundwater contamination …

WebbExamples of some plant species used for phytovolatilization are presented in Table 6. 3.5. Rhizofiltration. Rhizofiltration is a technique for the assimilation of pollutants present in a solution adjoining the root zone, concentrating and precipitating them on or into plant roots through biotic or abiotic methods (Figure 5b). Webb1 sep. 2024 · Phytovolatilization. Plants are used to convert different pollutants into less hazardous volatiles, which are then released into the atmosphere through the foliar system. This concept may be used to remove organic pollutants as well as heavy metals including Se, Hg and As (Yan et al., 2024).

Webb15 juni 2016 · PDF - Plants can interact with a variety of organic compounds, and thereby affect the fate and transport of many environmental contaminants.
