Abstract This study investigated the retreated area of Urumqi Glacier No.1in the Tianshan Mountains and its chronological succession sequence was determined using ²¹⁰Pb_ex and ¹³⁷Cs radioactive isotope dating and erosive accumulation landforms. Based on this, a network of sampling points was created to stratify the soil, measure the total mercury concentration and other indicators of the sample, and calculate the mercury accumulation rate. The aim of this study was to investigate the distribution and accumulation of mercury in the soil of the retreated area of Urumqi Glacier No.1in the Tianshan Mountains. The results show that the mercury content of different soil layers in the glacier retreated area increased with the increase in its retreated time, specifically 0~5cm [(13.28 ± 6.60) µg/kg] >5~10cm [(11.47 ± 7.34) µg/kg] >10~15cm [(10.19 ± 6.57) µg/kg] > bedrock [(0.23 ± 0.09) µg/kg]. Soil mercury storage increased with retreatment time. Furthermore, there was a positive correlation between mercury concentration and organic carbon/nitrogen content at different soil levels within the retreated area, indicating that they have a significant impact on the spatial distribution of soil mercury. The soil in the retreated area of Tianshan No.1Glacier accumulated less mercury (0.09~33.43µg/(m²×a), with an average value of 16.92 µg/(m²×a). Mercury levels in soil increased from (0.09µg/(m²×a) in 1777 to (33.43µg/(m²×a) in 2017.
