Oxidation Technology

In this paper, Fenton oxidation technology was used for oxidation treatment of soil contaminated by heavy oil, and environmental conditions were investigated for improving the effect of Fenton oxidation. The results showed that under the direct sunlight, liquid to soil was 2:1, pH was 5, 10.0mL 18 mmol•L-1 Fe2+ and 10.0mL 30%H2O2 were added to 1000g soil contaminated by heavy oil which contained 8% petroleum hydrocarbons, the petroleum hydrocarbons reduced from 5.74% to 2.92%.

The Relationship

Based on the process of health risk assessment for Cd contaminated sites, study the relationship between exposure duration and recommended target of soil remediation. This paper discusses the changes (from 7.7 mg/kg to 5.0 mg/kg, from 9.1 mg/kg to 3.8 mg/kg) of recommended target for soil remediation when the exposure duration has large changes (EDa ranges from 6a to 36a, EDc ranges from 1a to 12a). The results point out that both EDa and EDc have effects on recommended target of soil remediation, and in general, exposure duration and recommended target of soil remediation vary inversely.

Exposure Methods

This paper describes the model of heavy metal-Cu contaminated soil remediation standard value based on risk assessment. In the Cu contamination risk assessment model, the main exposure methods are oral ingestion and inhalation through breathing, which not only simplifies the calculation but also make people get a clearer understanding of the way of Cu contamination. We get the simplified formula, calculate and discuss Cu contaminated soil remediation target value in specific parameters to provide reference and basis for the remediation of Cu contaminated soil.
