| Abstract: | "To study the emission characteristics of volatile organic malodorous compounds and identify the characteristic substances of associated industries, the components of VOCs of typical industries were detected and analyzed in an industrial area of south China. The results showed that there are certain differences in the material composition among different companies, and there are also certain differences in the composition of different processes in the same company. For the automobile manufacturing industry, alcohols and esters were the main substances in the spraying workshop, accounting for 21.87% and 21.62%, respectively, and aromatic hydrocarbons were the typical substances in the drying workshop, accounting for 41.14%. Concerning the electronic components industry, esters were the main substances, accounting for 67.99% in the spraying and coating workshop. Regarding the coating production industry, esters were the main substances in the two paint companies, but the emission ratio of aromatic hydrocarbons was the second highest in one company and the emission ratio of ketone was the second highest in the other company. For the printing industry, alcohols were the characteristic substances, accounting for 99.32%. Concerning the refrigeration industry, alkanes were the most abundant compounds, accounting for 83.01%. Esters (ethyl acetate, butyl acetate, and isobutyl acetate), aromatic hydrocarbons (toluene, ethylbenzene, and styrene), and alcohol ketones (ethanol, methyl isobutyone, and 2-butanone) were preliminarily identified as characteristic malodorous compounds of the industries using organic solvents" |
