黄河是当地工农业用水的主要水源，也是当地饮用水的主要来源。在这项研究中，对包头地区的8个水样进行了分析，其中使用等离子体质谱法和还原气化 - 原子荧光光谱法检测了重金属（镉、锌、铜、铅、铬、汞和砷）含量。通过高通量测序对8个水样中的水生细菌属进行了研究。结果表明，所有重金属含量均超过中国国标标准，这意味着包头地区的黄河水有被污染的风险。此外，发现了大量条件致病菌（黄杆菌属、假单胞菌属、金黄杆菌属和不动杆菌属），一些细菌（如甲烷杆菌）可以分解有害物质和有机物。总之，根据这项研究，我们试图为包头地区黄河污染控制提出重要参考。
The Yellow River is the main water source for local industrial and agricultural use, and also the main source of local drinking water. In this study, eight water samples of Baotou region were analyzed, in which the heavy metal (Cd, Zn, Cu, Pb, Cr, Hg and As) content were detected using plasma-mass spectrometry and reduction gasication–atomic fluorescence spectrometry. Genus of water bacteria in eight water samples were investigated by means of high-throughput sequencing. Results showed that all the contents of heavy metals exceed GB (GuoBiao) standard of China, which implied the water of the Yellow River in Baotou region are at risk of being polluted. Furthermore, a large number of conditioned pathogens (Flavanobacteria, Pseudomonas, Chryseobacterium and Acinetobacter) were found, some bacteria (such as Methanobacteria) can break down harmful substance and organic matter. In conclusion, according to this study, we try to put forward an important reference for the pollution control of Yellow River in Baotou area.
