Chemical Fixation of Heavy Metal-Contaminated Soils
The U.S. Environmental Protection Agency (EPA) has been working toward the establishment of treatment standards for contaminated soils. The Office of Emergency and Remedial Response is in the process of developing and carrying out a plan to address the data needs for establishing the Pest Demonstrated Available Technologies (BDAT) for Superfund soils. The BDAT program is divided into phases. Ph...
متن کاملEffects of metal phytoextraction practices on the indigenous community of arbuscular mycorrhizal fungi at a metal-contaminated landfill.
Phytoextraction involves use of plants to remove toxic metals from soil. We examined the effects of phytoextraction practices with three plant species (Silene vulgaris, Thlaspi caerulescens, and Zea mays) and a factorial variation of soil amendments (either an ammonium or nitrate source of nitrogen and the presence or absence of an elemental sulfur supplement) on arbuscular mycorrhizal (AM) fun...
متن کاملAntimicrobial efficacy of chemical disinfectants on contaminated full metal crowns.
Prosthetic restorations that have been tried in the patient's mouth are potential sources of infection. In order to avoid cross-infection, protocols for infection control should be established in dental office and laboratory. This study evaluated the antimicrobial efficacy of disinfectants on full metal crowns contaminated with microorganisms. Full crowns cast in a Ni-Cr alloy were assigned to ...
متن کاملFrom green to clean: a promising and sustainable approach to remove toxic metals from contaminated soils
Phytoextraction is an in situ decontamination technique using metal accumulating plants and appropriate soil amendments to transport and concentrate metals from the soil into the aboveground parts of plants, which are harvested with conventional agriculture methods. Since most of the metal hyperaccumulating plants only produce very low biomass, and most of plants producing high biomass accumula...
متن کاملPhytoextraction of Cd-Contaminated Soils: Current Status and Future Challenges
Cadmium (Cd) is one of the most toxic and widely distributed pollutants in the environment. Cadmium contamination of soils has posed a serious threat to safe food production in many parts of the world. The authors present a comprehensive review of present status of phytoextraction technology for cleaning up Cd-contaminated soils, based primarily on the data resulting from both laboratory and fi...
