Non-negligible contribution of high-level volatile sulphur compounds to ozone photochemical formation in an industry zone in the North China Plain
The increasing amount of ozone (O3) pollution in China is attracting extensive scientific attention globally. This study presents direct evidence that high concentrations of volatile sulphur compounds (VSCs) accelerate the photochemical production of O3. We analysed three high O3 cases (Cases I, II, and III) in which the O3 concentrations were high but the compositions of O3 precursors differed. An analysis of the O3 precursors and the magnitudes of the associated ROx (ROx = ·OH + ·HO2 + ·RO2) reactivities amongst three cases revealed that VSCs may play an important role in O3 production. Case I showed high loadings of VSCs, mainly dimethyl sulphide (DMS), and the simulated diurnal average concentration of radicals and the net O3 production rate were higher than those in Cases II and III, reflecting the higher photochemical reactivity and oxidation capacity of Case I. Although O3 was mainly produced from the oxidation of aromatics in all cases, the oxidation of DMS was an important contributor to O3 formation in Case I (14%) and Case III (25%). The combined analyses indicated the contribution of DMS to O3 production in industrial areas and suggested the urgent need to measure related VSCs during field campaigns in another atmospheric environment to verify this phenomenon.
期刊介绍：
Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health.
It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes.
International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals.
Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements.
This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
