[Mercury pollution and its ecosystem effects in Wanshan mercury miner area, Guizhou].
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 24.31-347.52 mg.kg-1, two or three magnitude higher than the average value of Chinese soils; mercury content in plants is 0.47-331.4 mg.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.
