“…In high-pollution episodes, the contribution of OM can be up to 48%, and SNA may comprise up to 40%, depending on sites (Huang et al 2014;Xie et al 2015;Wang et al 2016). It is noted that the contribution of SNA in PM 2.5 in the present study was apparently higher than published results for other cities (Cheng et al 2016a, b;Song et al 2017) and also higher than our previous study (Shen et al 2014a, b). One probable explanation is the difference in sampling site height.…”

“…For example, OM contribution can range from 16 to 53%, while SNA contribution ranged from 15 to 55% (Cheng et al 2016a, b). Based on published data in the literature, Song et al (2017) found that in China, SNA and OM on average contributed 37 and 23% of the total PM 2.5 mass, respectively. In high-pollution episodes, the contribution of OM can be up to 48%, and SNA may comprise up to 40%, depending on sites (Huang et al 2014;Xie et al 2015;Wang et al 2016).…”

“…7 Relationship between EC and BC in PM 2.5 the lacking of element information; however, it seems that the mass contribution of dust components was in 10%. In past studies, particle chemical compositions and profiles vary largely in sites and periods (Cheng et al 2016a, b;Philip et al 2014;Snider et al 2016;Song et al 2017). Results from the SPARTAN (the Surface PARTiculate mAtter Network) showed that major PM 2.5 constituents were ammoniated sulfate, crustal material and residual matter, contributing 20 ± 11, 13 ± 10 and 40 ± 24%, respectively (Snider et al 2016).…”

“…Some past studies had investigated chemical compositions of ambient particles (Niu et al 2016;Shen et al 2014a, b;Song et al 2017 and references therein), most of which are based on off-line filter analysis and from ground stations in mega/large cities. Studies on chemical compositions of particles in western YRD and their temporal variations are still limited.…”

Understanding particle chemical composition is important in source apportionment and health impact assessment. Since 2012, a Complex Air Pollution Research Station located on the top roof of a 22-floor building (*80 m) in Jiangsu Provincial Academy of Environmental Science was established as a platform to characterize components and temporal variations of hazy and air transport in the region, so as to provide scientific supports on Joint Prevention and Control of Regional Air Pollution control in the Yangtze River Delta. Here, based on 1-year online measurement, we present a preliminary result on occurrence of ambient particles and chemical components, and reconstructed light extinction coefficients based on measured species. In 2015, the annual average concentration of PM 2.5 was 68 ± 40 lg/m 3 , comprising up to nearly 75% of the total PM 10 . The submicron PM 1.0 had an annual average concentration of 48 ± 28 lg/m 3 and contributed about 70% of the total PM 2.5 mass. Secondary inorganic composition including sulfate, nitrate and ammonium (SNA) was the major fraction of PM 2.5 , accounting for *70% on an annual average. The estimated light extinction of ambient particle averaged at 422 ± 256 Mm -1 , of which 412 ± 257 Mm -1 was induced by fine PM 2.5 . SNA contributed largely to the light extinction induced by fine PM 2.5 (about 72%), followed by organic matter (18%).During the high-pollution episodes, the mass fraction of SNA increased notably, calling for necessary controls on key gaseous precursors.

“…Так, например, в Китае свыше 1,3 млрд жителей подвергаются воздействию загрязненного PM воздуха в концентрациях, существенно превышающих стандарты ВОЗ. С использованием интеграционного подхода «воз-действие -реакция» и с помощью моделирования было установлено, что в 2015 г. загрязнение воздуха мельчай-шими PM способствовало 40,3% всех смертей от инсуль-та, 26,8% -ишемической болезни сердца, 23,9% -рака легких, 18,7% -ХОБЛ [6].…”

В обзоре даны современные представления о связи загрязнения атмосферного воздуха взвешенными частицами с заболеваемостью и смертностью от хронических неинфекционных заболеваний. Рассмотрены результаты кра-тковременного и долговременного влияния взвешенных частиц на патогенез хронических неинфекционных за-болеваний в зависимости от их размера, происхождения, химического состава, концентрации в воздухе. Ключевые слова: загрязнение воздуха, взвешенные частицы, патогенез, хронические неинфекционные заболевания Конфликт интересов: авторы заявляют об отсутствии конфликта интересов Прозрачность финансовой деятельности: никто из авторов не имеет финансовой заинтересованности в представленных материалах или методах Для цитирования: Колпакова А.
