Abstract

In order to reveal the characteristics of odorous compounds released during the collection and transportation of municipal solid waste, typical compression and uncompressed vehicles for waste collection were monitored for 12months. 75kinds of odorous compounds were detected and classified into 6categories, among which the oxygenated compounds dominated by ethanol accounted for the highest proportion in concentration with the average concentration of higher than 360μg/m³. The corresponding odor pollution was more significant in autumn than that in winter. According to the statistical analysis of all the monitored data, there was no significant difference in type and concentration of odorous compounds between the compressed and uncompressed vehicles for waste collection. Five typical odorous compounds, including ethanol, naphthalene, dichloromethane, dimethyl disulfide and acrolein, were identified by using dilution multiple method. Due to the low olfactory threshold, the sulfur compounds can easily be detected by human even in very low concentrations, and should be paid more attention to during odor pollution control. This study provides important scientific information for the secondary pollution control of solid waste collection, transportation and management.
