Source Apportionment and Risk Assessment of Atmospheric Polycyclic Aromatic Hydrocarbons in Lhasa, Tibet, China

n‐Alkanes and PAHs in the Southeastern Tibetan Plateau: Characteristics and Correlations With Brown Carbon Light Absorption

“…Higher concentrations of PAHs were reported in the winter-spring season. The major source region of these organic species was the Indo-Gangetic Plain (Chen et al, 2014(Chen et al, , 2017(Chen et al, , 2018Gong et al, 2018;Wang et al, 2015Wang et al, , 2018. southeastern TP) is to the west of the Yarlung Tsangpo Grand Canyo with two typical air circulation patterns, which is conducive to assess the pollutants variations and transport patterns in the area (Wang et al, 2015).…”

Positive matrix factorization on source apportionment for typical pollutants in different environmental media: a review

“…38 Ambient temperature and long range transport driven by the east Asian monsoon were both factors affecting the variation in source categories. 39,40 However, for countries beyond China, such as Egypt 5 , Spain 41 , Turkey 42 , Iran 43 , Malaysia 44 and Nepal 45 , the sources of PAHs in the atmosphere were generally associated with petroleum usage including gasoline/diesel emission, natural gas combustion and stationary sources from industrial activity.…”

“…in various urban areas, including China [38][39][40] , India 46,47 and Iran [48][49][50] as summarized in part of Figure 6. It may be concluded that the common sources of atmospheric PAHs in these regions have been relatively stable over the past 10 years although contribution ratios have fluctuated.…”

Effects of Plateau Air Quality and Low Oxygen Content on Platelet mtDNA Methylation and High Altitude Pulmonary Edema

“…For example, external forces such as aerosols and greenhouse gases that change the climate on the Tibetan Plateau in response to teleconnection are elementary problems now arise (Ma et al, 2020). It has been reported that the atmosphere in Lhasa, the largest city in Tibetan Plateau, had been severely influenced by local emissions due to the current rapid urbanization and industrialization (Chen et al, 2018). However, the air quality was relatively better in Lasha in comparison with other provincial capital cities in China (Yin et al, 2019).…”
