Abstract: Ten typical livestock (layer, dairy, swine) farms in Shanghai were selected as the research object. The characteristics of odor pollutants emissions of typical livestock and poultry farms and different emission stages were investigated by using on-site sampling and laboratory analysis. It was shown that the odor concentration of each farm boundary was between<10 and 128. The odor concentrations of main odor emission stages in layer farms, dairy farms and swine farms were 10-412, 10-511 and 10-538, respectively. Manure composting of the layer farms, waste water storage of the dairy farms and housing of swine farms had greater odor emission than the other odor emission stages of the according livestock and poultry farms, to which more attentions should be paid. There were significant (P<0.01) correlations within NH3, H2S contents and odor concentration in swine farms, yet these correlations were not significant in dairy farms. Organic fertilizer production could reduce the odor concentration effectively as compared with simple composting in the manure treatment stage.
