| Abstract: | "Odor nuisance is the main incentive for Not In My Back Yard campaigns around municipal solid waste (MSW) waste disposal facilities, and the odor identification is of significance for the understanding of the odor properties from MSW with different disposal methods. In this study, odor emissions from different stages at two large-scale working MSW disposal facilities, i.e., landfill (LF) and compost plant (CP), were distinguished with the same MSW feedstock in one city. It was found that CP suffered the heavier odor pollution and the characteristics of odorants changed significantly, especially the pile-turning workshop. Sulfides and aromatics were the main concentration contributors for LF, while that for CP were NH(3) and oxygenated compounds. Significant correlations between odor concentration and halogenated compounds, sulfides (r(2)?ª+=?ª+0.945, 0.898, p<0.05, n?ª+=?ª+12) were merely observed in CP. The priority odor pollutants of LF were H(2)S, benzene and NH(3), while that of CP was NH(3), ethyl acetate and benzene with a descending order. With regarding to their contributions for occupational exposure, the carcinogenic risk was negligible for these facilities, but H(2)S of LF might bring non-carcinogenic risk to on-site workers" |
