摘要
小铅矿开采已对宁南县造成污染。银厂沟（污染区）丰水期１１个水样中９个铅含量超标０．４９～１８．９９倍，河泥含铅量为对照的１０５．１倍。污染区土壤含铅量（７３８．４±５８０．９ｍｇ／ｋｇ）明显高于对照（２５．５±６．９ｍｇ／ｋｇ）．Ｐ＜０．０１．采矿洞空气铅尘浓度超标１６４．４（１．４～４８９．０）倍。污染区小麦（０．４４±０．１９ｍｇ／ｋｇ）等含铅量明显高于对照（０．２６±０．１９ｍｇ／ｋｇ），Ｐ＜０．
ead pollution of grain and environmant have been arisen form
mining lead in NingnanCounty. The concentration of lead in 9/11 samples taken in the polluted
Yingchanggou areawas 0. 49～18. 99 times higher than Health Standard. The lead
concentration of river soid was105. 1times as much as control (P<0. 01). The Lead
Concentration in the samples of pollut-ed soid was significantly higher than that in control (P<0.
01). The lead dust concentrationin the air of mining caves exceeded Health Standard by 164.
4(1. 40～489. 0)times. The leadconcentration of grain, as wheat polluted area (0. 44 ± 0.
19mg/kg) was also significantlyhigher than that in control (P<0. 01).
