| 中文摘要 |
| 通过对贵州万山汞矿地区环境样品(水、土壤、植物、农作物和动物)的系统研究,发现该地区的环境汞污染以土壤、大气污染为主,水体基本处于正常范围.土壤汞含量为24.31～347.52mg·kg-1,比全国土壤平均值高出2～3个数量级;水中汞含量除了冶炼厂荷花池中含量较高外,其它水体为0.10～0.68ng·mL-1.由于矿山长期的开采和冶炼,整个环境的汞污染严重,当地的植被、农作物、动物中存在明显的汞蓄积,各种植物不同部位的汞含量为0.47～331.4mg·kg-1;苔藓可以高度富集汞. |
| 英文摘要 |
| Samples of water, soil, plants, crops and animals collected from Wanshan mercury miner area, Guzhou Province, were analyzed with an AMA 254 liquid/solid mercury analyzer. It was shown that mercury pollution is mainly in soil and air; except water from a pool, no anomaly mercury is found in waters. Mercury content in soil is 24.31～347.52mg·kg-1, two or three magnitude higher than the average value of Chinese soils; mercury content in plants is 0.47～331.4mg·kg-1, and moss can enrich much mercury. Due to the long time of exploration and smelting, abundant mercury are accumulated in the local ecosystem, and healthy of local people are threatened seriously. |
