Abstract

Abstract

In this study, the concentrations of major air pollutants in Luohu District of Shenzhen in 2019 were statistically analyzed, the trend of conventional air pollutant concentration in Luohu District was explored, and the correlation between atmospheric pollutant concentration and meteorological factors in Luohu District was analyzed. The potential source analysis of two pollution events in Luohu District in 2019 was analyzed, the principal component analysis of the main pollutant ozone in Luohu District was carried out, and finally, air pollution control suggestions and countermeasures were put forward for Luohu District. The results showed that the concentration of air pollutants in Luohu District in 2019 was greatly affected by the season, and there was a weekend effect, among the 348 effective data of the year. The number of days with the main pollutant as ozone was 225, accounting for 64.66% of the whole year, and the main pollutant in Luohu District in 2019 was ozone. The correlation between particulate matter concentration and other pollutants in Luohu District was significant, and the concentration of pollutants in the atmospheric environment was significantly correlated with temperature, wind, and relative humidity. The results of the analysis of the potential sources of the two air pollution events showed that the northeast direction including Dongguan etc., was the potential input source of O₃ and PM_2.5 in Luohu District. Four principal components were analyzed through the analysis of the principal component of ozone concentration, of which the first component could explain 59.2% of the ozone concentration, and the main factors affecting atmospheric ozone concentration in Luohu District were wind, humidity, PM_2.5, PM₁₀ and SO₂. This study provides a reference for the control and treatment of air pollution in Luohu District.
