Abstract
Abstract Rural waste samples were taken from one classical dumping site in Ningbo to detect the heavy metal contents and evaluate the contamination potential. The experiment results show that the average heavy metal content in the rural waste followed the sequence of Zn> Cu>Cr >Pb> Cd, and their corresponding contents were 692.0±900.9, 402.6±452.4, 196.3±299.6, 167.3±124.5 and 3.9±4.5 mg/kg, respectively. The rural waste contains high organic material and N, implying they could provide nutrients and organic matter simultaneously to be compost. However, the rural waste could only be applied in the lawn planting to avoid the contamination of the food chain.
