Change Characteristics and Source Apportionment of Ozone Pollution in Sanya City in 2019
Sanya has geographical and climatic characteristics such as low latitude, high temperature, high salt, high humidity, and strong solar radiation all year round, which is conducive to the occurrence of photochemical reactions; therefore, the problem of ozone photochemical pollution in Sanya needs to be solved urgently. This article is based on the hourly data of O3 and NO2 in Sanya City in 2019, various collected meteorological data, and online monitoring of VOCS major species data to analyze the characteristics of ozone pollution changes and source apportionment in Sanya City. The results indicate that the daily variation characteristics of ozone pollution in Sanya City conform to the typical characteristics of ozone photochemical pollution events, and the EKMA curve indicates that Sanya City as a whole belongs to a NOX-sensitive area. The OH consumption rate (LOH) and ozone generation potential (OFP) indicate that the key active components of VOCS are mainly isoprene, ethylene, n-butane, propane, etc. The corresponding main potential sources of emissions include combustion emissions, solvent volatilization, and automotive exhaust emissions. The O3 emission reduction plan is to reduce the ozone concentration from 180 to 158 µg·m−3, corresponding to a 25 and 20% reduction in the concentrations of the two main precursors, NOX and VOCS, respectively. This article provides scientific support for the problem of ozone photochemical pollution in Sanya City.
期刊介绍:
ASE is an international journal that publishes high-quality papers, communications, and discussion that advance aerosol science and engineering. Acceptable article forms include original research papers, review articles, letters, commentaries, news and views, research highlights, editorials, correspondence, and new-direction columns. ASE emphasizes the application of aerosol technology to both environmental and technical issues, and it provides a platform not only for basic research but also for industrial interests. We encourage scientists and researchers to submit papers that will advance our knowledge of aerosols and highlight new approaches for aerosol studies and new technologies for pollution control. ASE promotes cutting-edge studies of aerosol science and state-of-art instrumentation, but it is not limited to academic topics and instead aims to bridge the gap between basic science and industrial applications. ASE accepts papers covering a broad range of aerosol-related topics, including aerosol physical and chemical properties, composition, formation, transport and deposition, numerical simulation of air pollution incidents, chemical processes in the atmosphere, aerosol control technologies and industrial applications. In addition, ASE welcomes papers involving new and advanced methods and technologies that focus on aerosol pollution, sampling and analysis, including the invention and development of instrumentation, nanoparticle formation, nano technology, indoor and outdoor air quality monitoring, air pollution control, and air pollution remediation and feasibility assessments.
