With the climate warming leading to thawing permafrost, the trace metal releasing from the permafrost is of increasing importance. The source area of the Yellow river (SAYR) in Tibet Plateau, underlain by permafrost which provides important source water, was investigated. One hundred and eleven water samples across SAYR were collected in April 2014, when permafrost thawing began and the precipitation season had not arrived yet. It was found that the arsenic concentration level was relatively higher than other pristine surface water in the world, but similar to other source regions on the Tibetan Plateau, showing SAYR is pristine and can serve as a reference region for determining the human influence on permafrost-affected landscapes. The positive correlation of arsenic with sulfate suggested that the arsenic was predominantly derived from the weathering process of arsenic-rich sulfides. Climate warming enhanced thawing depth of permafrost may accelerate the release and mobilization of arsenic to the surface water.

随着气候变暖导致永久冻土融化，从永久冻土中释放出来的微量金属变得越来越重要。对青藏高原黄河（SAYR）的源区进行了多年冻土（提供重要水源）的调查。2014年4月，当永久冻土融化开始且降水季节尚未到来时，在SAYR上收集了111个水样。研究发现，砷的浓度水平高于世界上其他原始地表水，但与青藏高原上的其他水源区域相似，表明SAYR是原始的，可作为确定人类对多年冻土影响的参考区域。受影响的景观。砷与硫酸盐的正相关性表明，砷主要来自富含砷的硫化物的风化过程。气候变暖增加了永冻土的融化深度，可能会加速砷向地表水中的释放和迁移。
