| 摘 要： | 广西河池市是我国重要的有色金属基地.以该市一个典型的矿业镇作为研究对象,采集了该镇周围23个旱地土壤样品,并在镇里布设两个大气采样点采集了可吸入颗粒物(PM10)样品,运用ICP-MS分析了样品中20种金属元素的含量,采用地积指数法判定旱地土壤和可吸入颗粒物中污染元素及来源.结果表明,这些与人们生活密切的环境介质(旱地土,可吸入颗粒物)均受到了多种重金属元素的复合污染,其共同的污染元素有Cd、As、Sb、Pb、Xn、Cu,而其中致癌元素Cd和As污染最为突出.大气可吸入颗粒物与旱地土壤中各污染元素的污染强度排序相同,均为Cd＞As＞Sb＞Pb＞Zn＞Cu.经过现场调查和识别,污染源主要来自当地开放性运矿产生的扬尘所致.因此加强该地区矿石运输管理是保护该地区耕地和人群健康的需要. |

| Abstract: | Guangxi Hechi city is an important nonferrous metal base of China.A total of 23 framland samples,and 2 PM_(10) samples on two spots of the town were collected at a typical mining town-Dachang Town,20 elements were analyzed by ICP-MS.The results showed that any media of above(dry land soil,PM_(10)) was enfronted with contamination of several heavymetal elements simultaneously.The common contaminated elements were: Cd,As,Sb,Pb,Zn,Cu.Morever,Cd and As were the most serious which implied that they would be most... |
