Soil remediation with PAHs
Summary: The original site of the relocated iron and steel enterprises may be caused by various harmful pollutants left over from the original production activities, such as heavy metals, polycyclic aromatic hydrocarbons, dioxins and titanate compounds. These pollutants can enter the surrounding soil of the industrial zone through atmospheric deposition and waste residue infiltration, resulting in serious soil pollution. When the original site is used for other purposes, such as residential and commercial purposes, heavy metals and organic pollutants in the soil environment will seriously affect human health, cause imbalance of immune system level, affect the central nervous system, some substances may affect the digestive system, and even damage the liver and hematopoietic system. Therefore, it is necessary to remediate the polycyclic aromatic hydrocarbon contaminated soil.
Washing with plant detergent can achieve most of the indexes of PAHs in qualified soil. Washing with plant detergent is very conducive to the degradation of microorganisms in later stage.
