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 کاملResistance of microbial populations in DDT-contaminated and uncontaminated soils
One DDT-contaminated soil and two uncontaminated soils were used to enumerate DDT-resistant microbes (bacteria, actinomycetes and fungi) by using soil dilution agar plates in media either with 150 mg DDT ml−1 or without DDT at different temperatures (25, 37 and 55◦C). Microbial populations in this study were significantly (p<0.001) affected by DDT in the growth medium. However, the numbers of m...
متن کاملAbundance and diversity of Archaea in heavy-metal-contaminated soils.
The impact of heavy-metal contamination on archaean communities was studied in soils amended with sewage sludge contaminated with heavy metals to varying extents. Fluorescent in situ hybridization showed a decrease in the percentage of Archaea from 1.3% +/- 0.3% of 4', 6-diamidino-2-phenylindole-stained cells in untreated soil to below the detection limit in soils amended with heavy metals. A c...
متن کاملBiosurfactant - Producing Bacte- Ria Found in Contaminated and Uncontaminated Soils
Microbially produced surfactants have been studied for microbially enhanced oil recovery (MEOR) and the bioremediation of hydrocarbons. However, most of these studies have used biosurfactants produced by one of a small number of pure-culture microbes isolated in a laboratory. In previous work, we determined that biosurfactant-producing microorganisms were naturally present at two hydrocarbon-im...
