Air pollution and health risk assessment in Northeastern China: A case study of Jilin Province

Abstract

In recent years, the pollution of the air environment has been increasing, which has seriously endangered human health. The large amount of coal burning and automobile exhaust emissions in winter have caused serious regional pollution, which has greatly increased the prevalence of respiratory disease of people. The purpose of this study is to use Jilin Province as an example to map out the environmental pollution status in Northeastern China, and to provide suggestions for the improvement of the atmospheric environment. Using the annual data of China's atmospheric monitoring, the atmospheric environment in Jilin was comprehensively analysed using ArcGIS, principal component analysis (PCA) and non-carcinogenic risk model calculations. The results showed that the temporal distribution of pollutants was winter > spring > autumn > summer, and the spatial distribution is decreasing from northwest to southeast. The PCA showed that the first principal components were PM2.5 and CO, and the second principal components were PM10 and O3. The main sources of air pollution were coal-fired (62.365%) and automobile emissions (19.153%). The non-carcinogenic risks of pollutants are all within the acceptable range (1 × 10−6), but as age increases, the risk gradually decreases, and the risk value of male is higher than that of female.

“…With low combustion efficiency, emissions of CO, PM 2.5 , black carbon (BC) and PAHs have a significant adverse impact on the indoor and ambient air quality. 36 Other research 37 confirmed that coal burning and automobile exhaust emissions caused serious regional pollution in winter, which greatly increased the prevalence of respiratory diseases. The government should strive to promote technologies and measures to improve the utilization of biomass energy.…”

Health risk assessment of heavy metals and poly-aromatic hydrocarbons in particulate matter adsorbed by indoor air purifiers

“…Particulate matter (PM), as an important pollutant in indoor air, has been a wide concern for many years. [3][4][5] The harm posed by PM is not limited by its own existence, 6 but also due to the attachment of heavy metals and polycyclic aromatic hydrocarbons (PAHs) and other harmful substances to its loose and porous structure. 7 Indoor PMs with different sizes can enter the human body in different ways.…”

Investigation of Indoor Polycyclic Aromatic Hydrocarbons (PAHs) in Rural Northeast China: Pollution Characteristics, Source Analysis, and Health Assessment

“…Particulates tend to reach deep into the body and have a negative impact on health. Relevant studies have shown that high levels of particulates exposure increase cardiovascular risk [2][3][4][5][6], respiratory disease [7][8][9][10], premature death [11][12][13], etc. The chemical substances contained in particulates, such as polycyclic aromatic hydrocarbons (PAHs) and heavy metals, pose a more serious health risk than particulates only [14,15].…”
