Abstract

Abstract

In this paper, hazard evaluation technology and technical process of remedial reagents applied in contaminated sites was explored and established, based on the requirements of the relevant laws and domestic regulations on soil pollution prevention and chemical management, in which physical, health and environmental hazards of the remedial reagents were mainly taken into account. The evaluation process mainly consisted of judgment and management of new chemicals, and identification of hazardous chemicals, and discrimination of their hazardous characteristics. Furthermore, remediation technology and remedial reagents for polluted soil and groundwater in contaminated sites in Shanghai were studied to verify the established technical process. Basic information on 135 contaminated site remediation projects in Shanghai was collected, and the remediation technologies and remedial reagents for typical contaminants were summarized. Hazardous characteristics of the remedial agents were then identified. For example, hydrogen peroxide, a conventional oxidant, could cause combustion or explosion if in high concentration, so a concentration of 60% below was advised. This study would provide innovative ideas, basic data, and technical support for the safe implementation of contaminated site remediation projects, safe use of remedial agents and soil remediation supervision by the ecological environment authorities in China.
