Anaerobic bioremediation of benzene under sulfate-reducing conditions in a petroleum-contaminated aquifer

Article Abstract:

Researchers from the University of Massachusetts studied the benzene degradation in a petroleum-contaminated aquifer and discovered that the addition of sulfates reduced the benzene and also the sulfate content of the aqueous body.

Study of thermally immobilized Cu in analogue minerals of contaminated soils

Article Abstract:

Copper (Cu) compounds are used in a case study to determine the effect of thermal treatment to fix soil contaminants. The leaching ability of Cu is graphed at temperatures ranging from 105 degrees Celsius up to 900 degrees Celsius.

Dissolved and labile concentrations of Cd, Cu, Pb, and Zn in aged ferrihydrite-organic matter systems

Article Abstract:

Cleaning up soil contaminated with heavy metals using ferrihydrite-organic matter is not a complete solution. Though some metals do precipitate, after about 200 days, sufficient amounts of some heavy metals persist at levels that can still cause phytotoxicity or can result in excessive uptake by crops. Some metals continue to percipatate even after the 200 day mark. However, tests were conducted for about 200 days. These findings result from tests conducted using separate and mixed iron oxide-organic matter systems.
