A field investigation was carried out on the distribution characteristics of heavy metals in the soils of electronic waste (e-waste) recycling location in Taizhou City, Zhejiang Province, China. The results showed that the concentrations of Cd, Cu and Pb were more than the Grade II values of soil quality standards from the State Environmental Protection Administration of China (SEPA), of which the most serious pollutants were Cd and Cu, followed by Pb. Based on the state standard values of soil quality in China, the comprehensive pollution index of Cd, Cr, Cu, Pb and Zn in the e-waste recycling locations was 4.3, that indicated that the e-waste recycling location's soil has been severely contaminated by heavy metals. Another result also showed that there existed compound pollution of Cu, Pb, Zn, Cr and Cd of the soils at test sites, and soils there were not suitable for agricultural cultivation any more.

Abstract


A field investigation was carried out on the distribution characteristics of heavy metals in the soils of electronic waste (e-waste) recycling location in Taizhou City, Zhejiang Province, China. The results showed that the concentrations of Cd, Cu and Pb were more than the Grade II values of soil quality standards from the State Environmental Protection Administration of China (SEPA), of which the most serious pollutants were Cd and Cu, followed by Pb. Based on the state standard values of soil quality in China, the comprehensive pollution index of Cd, Cr, Cu, Pb and Zn in the e-waste recycling locations was 4.3, that indicated that the e-waste recycling location's soil has been severely contaminated by heavy metals. Another result also showed that there existed compound pollution of Cu, Pb, Zn, Cr and Cd of the soils at test sites, and soils there were not suitable for agricultural cultivation any more.
