The exhaust gases from different coating processes in Jinhua were analyzed by gas chromatography and mass spectrometry (GC-MS) to obtain the VOCs composition spectrum. Toluene, xylene and ethyl acetate were applied as the characteristic pollutants to study the ozone pollution situation of different coating waste gases and evaluate their health risks. The results showed that the concentrations of VOCs emitted were 97.83~2237.53 mg·m-3. The corresponding ozone formation potentials were 336.22~6725.63 mg·m-3, while ethyl acetate was the largest contributor. After the paint mist separation process, the non-carcinogenic risk of the characteristic pollutants can be effectively controlled.
