This work presents coal analyses for heavy metal content (Tl, Cu, Zn, Cd, Fe). The tested coal samples came from a Russian deposit in the Kuzbass Basin (Novosibirsk and Kemerovo Oblasts, near Kazakhstan) and from Poland. The concentration of thallium in coal was determined using DPASV-differential pulse anodic stripping voltammetry-and other metals were examined with FAAS, i.e., flame atomic absorption spectrometry. The study confirmed the presence of thallium in the tested coal sample. The coal samples from outside the European Union contained four times more thallium (the maximum content of thallium in coal has been determined to be 0.636 mg·kg) than the samples of Polish coal (where the maximum content of thallium was 0.055 mg·kg). Cadmium concentration was on average 1.99 mg·kg in the samples from outside the European Union, and 1.2 mg·kg in the samples of Polish coal. Zinc concentration in the samples from outside the European Union was on average 11.27 mg·kg, and in the samples of Polish coal approx. 7 mg·kg. In addition, iron concentration in all coal samples was determined as 14.96 mg·kg, whereas copper concentration in the samples from outside the European Union averaged as 3.96 mg·kg. The obtained results do not show any correlation between the presence of thallium and the presence of other metals. It is worth noting that heavy metals pose a threat to living organisms due to their persistence and bioaccumulation, particularly in the context of dust emissions to the atmosphere.
这项工作展示了对重金属含量（铊、铜、锌、镉、铁）的煤炭分析。测试的煤样来自俄罗斯库兹巴斯盆地的一个矿床（新西伯利亚州和克麦罗沃州，靠近哈萨克斯坦）以及波兰。使用差分脉冲阳极溶出伏安法（DPASV）测定煤中铊的浓度，其他金属则用火焰原子吸收光谱法（FAAS）进行检测。该研究证实了测试煤样中存在铊。来自欧盟以外地区的煤样所含铊量是波兰煤样的四倍（已确定煤中铊的最大含量为0.636毫克·千克），波兰煤样中铊的最大含量为0.055毫克·千克。欧盟以外地区煤样中的镉平均浓度为1.99毫克·千克，波兰煤样中的镉平均浓度为1.2毫克·千克。欧盟以外地区煤样中的锌平均浓度为11.27毫克·千克，波兰煤样中的锌平均浓度约为7毫克·千克。此外，所有煤样中的铁浓度测定为14.96毫克·千克，而欧盟以外地区煤样中的铜平均浓度为3.96毫克·千克。所得结果并未显示铊的存在与其他金属的存在之间存在任何相关性。值得注意的是，重金属因其持久性和生物累积性，尤其是在向大气排放粉尘的情况下，对生物体构成威胁。
