Characteristics and Causes of Urban Ozone Pollution——A Case Study of 5 Cities in Shandong Province
In order to control air pollution in Shandong province more effectively,this paper analyzes the air qual-ity status of Shandong Province from 2014 to 2022,finds the existing problems of air quality in Shandong Prov-ince,and analyzes the changes of ozone concentration in 2021 in Jinan,Yantai,Weihai,Weifang and Dongying.The emission of nitrogen oxides and volatile organic compounds and their sources in different cities are analyzed.The differences in the sources of ozone pollution in different cities due to the differences in urban development,population and industrial enterprises are studied,and the causes of the current ozone pollution trend in Shandong are analyzed.For example,the energy structure is unreasonable.The living source lacks supervision,and the in-dustrial source governance process is single.Thus,targeted opinions and suggestions are put forward,such as a-dopting a combination of various treatment processes for industrial sources,improving the energy structures,de-veloping green energy and green travel as well as focusing on the control of living sources,and precise govern-ance.
