In order to study the correlation and distribution characteristics of arsenic (As 75) and other trace elements in the water of plateau rivers, the trace elements in the water of Yalong River in July 2021 (wet season) and November 2021 (dry season), an important tributary of the Yarlung Zangbo River, were investigated and analyzed. Based on correlation analysis, cluster analysis and principal component analysis, the relationships among arsenic 75 (As 75), boron 11 (B 11), iron (Fe 57), strontium 88 (Sr 88), tin 118 (Sn 118), lithium 7 (Li 7), vanadium 51 (V 51), cobalt 59 (Co 59), nickel 60 (Ni 60), copper 63 (Cu 63), zinc 66 (Zn 66), selenium 82 (Se 82), molybdenum 98 (Mo 98) and lead 208 (Pb 208) in water were explored. The results show that there are significant differences among the elements in wet season and dry season, which can be divided into three categories: The elements with stable contents in wet season and dry season (Ni 60, Co 59, Cu 63, Li 7, Zn 66); The elements with obvious seasonal variation (Sr 88, V 51, Mo 98, Li 7, Se 82, As 75, B 11, Pb 208); Elements less associated with other elements (Sn 118). In addition, most of the trace elements in the Yalong River Basin are related to Ni 60, Co 59, Cu 63, Li 7 and Zn 66. The study can provide scientific basis for understanding the changes of water environment in the basin and subsequent environmental protection.
