宁德市大气臭氧污染现状及影响因素

以宁德市蕉城区农机局、市监测站国控监测点2016年1月到2017年7月臭氧8小时监测值为基础,研究臭氧浓度的日变化、月变化趋势及臭氧相关影响因素,结果表明:在高温、低湿、低风速、晴朗无云的情况下,易形成高浓度臭氧;低温、高湿、少日照不利于臭氧的生成.现实情况中可能存在跨区域输送或区域内生成等情况都会导致臭氧污染的生成不...

Current situation and influencing factors of atmospheric ozone pollution in Ningde

Basing on the data of 8-hour monitoring values of ozone collected by Ningde Jiaocheng Agricultural Bureau and Ningde Monitoring Stations from January 2016 to July 2017,the researcher studied the tendency of diurnal variation and monthly variation of the concentration of ozone and some factors that have effects on the concentration.The results show that the conditions of high temperature,low humidity,low wind velocity,and bright weather contribute to the formation of high-concentration ozone,while the conditions of low temperature,high humidity and less sunshine would significantly lower the concentration of ozone.It should also be acknowledged that the possibility of cross-regional transmission of ozone or its precursors,or of intra-regional formation of ozone due to pollution emission or local chemical reactions could influence the concentration of ozone as well.
