Conclusions This study made use of two years of EBC concentration measurements at seven wavelengths in an urban area in Xuzhou, China. We found that the EBC concentrations in Xuzhou throughout the heating season were substantially higher than those throughout the nonheating season, as well as the brown carbon content material L-Cysteic acid (monohydrate) Autophagy Through the heating season was higher than that throughout the nonheating season. When it comes to the supply of EBC, our study shows that the source through the heating season is primarily coal and biomass utilised for heating. The sources of aerosols during the nonheating season primarily consist of petroleum along with other liquid sources made use of for transportation. Through the period of high EBC concentrations, the heating season was mainly concentrated during the Chinese Spring Festival, and the nonheating season was concentrated throughout periods of low rainfall. Backward trajectory evaluation shows that during the heating season, the vast majority of EBC concentrations are derived from northern and northwestern winds. The results show that the provinces towards the north are the main source of EBC in Xuzhou. The potential source contribution function (PSCF) model obtains similar final results as the backward trajectory evaluation. The majority on the heating season pollution comes from the north, and the sources in the nonheating season are evenly distributed from the area surrounding Xuzhou. As a result, these final results indicate that EBC emissions during the heating season in northern China, including those of Xuzhou, are high and that there’s a threat that pollutants will diffuse into low-concentration Cy5-DBCO Purity & Documentation regions within the atmosphere. Though controlling EBC emissions and suppressing pollution sources, interest need to be given towards the diffusion of pollution sources.Author Contributions: Writing, visualization, formal analysis, G.S.; methodology, W.C.; conceptualization, H.Z.; supervision, S.S.; validation, Y.W.
