Samples of water, soil, sediment, and pomegranate were collected from Xi'an and the Qinshihuang Mausoleum in Shaanxi Province, China to assess the effects of human activities on mercury in the environment. The total mercury concentrations ranged from 3.9 to 992.7ngL(-1) for the water samples, 40.6 to 2204.0ngg(-1) for the soil samples, 14.2 to 376.7ngg(-1) for the sediment samples, and 0.22 to 1.74ngg(-1) for the pomegranates samples. The higher values in the water samples collected from the rivers closer to and downstream of the city resulted from wastewater discharges. The effects of the mercury buried in the Qinshihuang Mausoleum thousands of years ago on the environment were neither significant nor widespread. Immediate actions should be taken to stop the direct and continuous discharges of industrial and residential wastewaters to prevent mercury and other pollutants from accumulating and spreading in the area.
从中国陕西省西安市和秦始皇陵采集了水、土壤、沉积物和石榴样本，以评估人类活动对环境中汞的影响。水样中总汞浓度范围为3.9至992.7纳克/升，土壤样本为40.6至2204.0纳克/克，沉积物样本为14.2至376.7纳克/克，石榴样本为0.22至1.74纳克/克。从城市附近和下游河流采集的水样中较高的值是由废水排放造成的。数千年前埋在秦始皇陵中的汞对环境的影响既不显著也不广泛。应立即采取行动，停止工业和生活废水的直接和持续排放，以防止汞和其他污染物在该地区积累和扩散。
