应用蚕豆根尖细胞微核技术评价广西平乐锰矿废弃地土壤的污染状况
Evaluation on soil pollution in Pingle Manganese Mine of Guangxi using Vicia faba root-tip cells micronucleus testing
摘要
Abstract
In order to study the pollution status of soil in Pingle Manganese 1Wine wasteland of Guangxi,four sampling plots respectively in peanut field,persimmon field,orange field ancl peach field were selected and investigated,the PI and MCN%o of root-tip cells under soil extracts from all plots were determined. By using micronudeus test technique of Vicia faba root-tip cells,this paper evaluated the pollution status of soil in Pingle Manganese Mine wasteland of Guangxi,and analyzed the reasons that might cause soil pollution. The results showed that the MCN%。 of root-tip cells of V. faba treated with the soils by means of maceration was obviously higher than that of the cells treated with the negative eontrol group(P<0. 05) ;orange field was under the most serious pollution,the PI had resched up to 2. 93,while peanut field got the least,the PI was 1.97. In conclusion, these indicated that the soil in this wasteland was more or less polluted,suggesting that it's not suitable for crops at the early stage of farming.关键词
