Conclusions This study made use of two years of EBC concentration measurements at seven wavelengths in an urban location in Xuzhou, China. We discovered that the EBC concentrations in Xuzhou throughout the heating season have been considerably larger than those through the nonheating season, and also the brown carbon content during the heating season was higher than that during the nonheating season. When it comes to the source of EBC, our study shows that the supply throughout the heating season is mostly coal and biomass applied for heating. The sources of aerosols through the nonheating season mostly consist of petroleum as well as other liquid sources utilized for transportation. Through the period of higher EBC concentrations, the heating season was mostly concentrated throughout the Chinese Spring Festival, plus the nonheating season was concentrated in the course of periods of low rainfall. Backward trajectory evaluation shows that throughout the heating season, the vast majority of EBC concentrations are derived from northern and northwestern winds. The outcomes show that the provinces for the north are the most important supply of EBC in Xuzhou. The possible source contribution function (PSCF) model obtains comparable final results as the backward trajectory analysis. The majority from the heating season DBCO-Maleimide References pollution comes in the north, and also the sources of the nonheating season are evenly distributed from the region surrounding Xuzhou. As a result, these outcomes indicate that EBC emissions through the heating season in northern China, such as these of Xuzhou, are higher and that there’s a danger that pollutants will diffuse into low-concentration places inside the atmosphere. Although controlling EBC emissions and suppressing pollution sources, focus need to be offered 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.
