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 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 کاملQuantitative assessment on soil enzyme activities of heavy metal contaminated soils with various soil properties.
Soil enzyme activities are greatly influenced by soil properties and could be significant indicators of heavy metal toxicity in soil for bioavailability assessment. Two groups of experiments were conducted to determine the joint effects of heavy metals and soil properties on soil enzyme activities. Results showed that arylsulfatase was the most sensitive soil enzyme and could be used as an indi...
متن کاملAssessment of Heavy Metal Contamination in Soils around of Khash Cement Plant, SE Iran
20 soil samples collected from the vicinity of the Khash Cement plant, Iran, were analyzed for As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb and Zn using ICP-OES. The results revealed that the metal distribution were in a fluctuating manner considering various distances and direction from the cement facility. However, it was observed that the mean concentration of the soil samples has no special trend wit...
متن کاملEffect of chelating agents on heavy metal extraction from contaminated soils
In the present study shacking and incubation experiments were carried out in order to evaluate the changes in heavy metal solubility in the studied soils by addition of different concentration of Ethylene dinitrilo tetra acetic acid (EDTA), Diethylene triamine penta acetic acid (DTPA), and Nitrilo tri acetic acid (NTA). The effects of EDTA, DTPA and NTA application on solubility of Copper (Cu),...
