This study assesses the air quality in Zabrze (southern Poland) based on the ambient concentrations of equivalent black carbon (eBC). eBC measurement campaigns were carried out from April 2019 to March 2020 using a modern AE33 Aethalometer, accompanied by parallel measurements of gaseous pollutants, PM₁₀ and meteorological parameters. The use of the two-component AE33 model allows for the determination of the eBC from fossil fuel combustion (eBC_ff) and biomass burning (eBC_bb). The obtained results showed a clear seasonal variability of eBC concentrations, with higher average levels in the heating season (4.70 µg·m⁻³) compared to the non-heating one (1.79 µg·m⁻³). In both seasons, the eBC_ff component had a dominant share in total eBC, which indicates significant emissions from the combustion of fossil fuels for heating purposes and from local traffic sources. The obtained results showed high correlation coefficients with gaseous and particulate pollutants, with the strongest relationship for eBC and carbon monoxide (CO). During the non-heating and heating period, both anticyclone and cyclone systems played an important role in shaping eBC, eBC_ff and eBC_bb concentrations. High concentrations of all components occurred with a significant decrease in air temperature and solar radiation in winter.

波兰南部大气中等效黑碳组分的时间变化

这项研究根据当量黑碳（eBC）的环境浓度评估Zabrze（波兰南部）的空气质量。eBC测量活动于2019年4月至2020年3月使用现代AE33湿度计进行，同时对气态污染物，PM ₁₀和气象参数进行了并行测量。两组分AE33模型的使用允许根据化石燃料燃烧（eBC _ff）和生物质燃烧（eBC _bb）确定eBC 。将所得到的结果表明：EBC浓度的清晰的季节变化，在采暖季节较高的平均水平（4.70微克·米^-3）相比，非加热一种（1.79微克·米^-3）。在两个季节中，eBC _ff成分在总eBC中占主要份额，这表明用于取暖目的的化石燃料燃烧和当地交通来源的大量排放。所得结果显示与气态和颗粒污染物的相关系数高，与eBC和一氧化碳（CO）的关系最强。在非加热和加热期间，反气旋和旋风系统都在影响eBC，eBC _ff和eBC _bb浓度方面起着重要作用。在冬季，所有成分的浓度都很高，空气温度和太阳辐射显着下降。
