研究人员在中国兰州发现石油化学物,而不是阳光,导致冬季臭氧污染。 Researchers find petrochemicals, not sunlight, cause winter ozone pollution in Lanzhou, China.

香港理工大学的研究人员发现,石油化学工业是中国兰州冬季臭氧严重污染的主要原因。 Researchers from Hong Kong Polytechnic University found that petrochemical industries are the main cause of severe wintertime ozone pollution in Lanzhou, China. 与共同的信念相反,该研究显示,臭氧是通过无阳光的阿尔肯人参与的反应形成的,而变性/cis-2-丁烷和丙烯是主要贡献者。 Contrary to common belief, the study shows that ozone forms through a reaction involving alkenes without sunlight, with trans/cis-2-butene and propene as major contributors. 减少高温或氮氧化物会降低臭氧水平,从而损害呼吸道健康,造成炎症和哮喘症状。 Reducing alkenes or nitrogen oxides could lower ozone levels, which harm respiratory health, causing inflammation and asthma symptoms.
