Abstract:		"According to the conditions of a contaminated soil and groundwater remediation site in Shanghai, the self-built electronic nose was applied to detect VOCs and odor of previously remedied soil and groundwater, remedying soil and groundwater, and the air above and around the site. Combining the formula of TPI and OPI, the value of each point was got and was shown in figures. Results showed: 1. Comparing the determination results of previously remedied with remedying contaminated soil and groundwater, the concentration of TVOC and odor was overall declined. The result was consistent with the fact. The detection result of electronic nose was proved to be right; 2. In the remediation process of soil and groundwater, the volatilization of VOCs and odor was inflected by temperature and works of crushing, adding medicine and turning the soil on time. The concentration showed a trend of overall decline with stage rising, so the electronic noses can be used for dynamic monitoring of the whole remediation process; 3. Combined with the GIS, the electronic noses can preliminary assess space pollution situation caused by the remediation of contaminated soil and groundwater and the influence on the residence in the surrounding region. However, further study on the refined classification of the impact degree is needed"
