Humic Substances as a Reductant for Hydrophobic Organic Compounds
Humic acids (HA) are ubiquitous redox-active compounds of natural aquatic and soil systems.They play a significant role in controlling the pollution of hydrophobic organic compounds in the soil.However,from a technological point of view,presence of HAs in sediments may have a significant influence on remediation action as a result of immobilization and the possible remobilization of pollutants.Here we have combined some information about the role of HAs in the sorption of organic contaminants from different sources in soil environment.Recent studies have shown the sorption ofpyrene by HAs increased as the aromatic carbon contents of HAs increased.HAs,which are naturally occurring surfactants,are beginning to be recognized as a one of the best possible aids in soil to enhance bioremediation techniques.Presently,HAs are considered one of the best natural supplements to remediate contaminated land.
