Abstract:

facing the problem of VOCs pollution, VOCs concentrations in urban Tianjin have been measured to identify their possible sources. Using positive matrix factorization, seven VOC sources are identified in urban Tianjin according to the factor loadings of various VOCs, including: 1) motor vehicle exhaust; 2) gasoline evaporation; 3) internal engine combustion emission; 4) diesel emission; 5) solvent usage; 6) industrial emission; and 7) biogenic emission. The identified sources of VOCs are significantly related to vehicular activities, which specifically contribute 60% to VOCs loadings in urban Tianjin, respectively. Controlling vehicle emissions should be top priority for VOCs reduction in Tianjin.
