| 摘 要： | 吉林省洁净地区长白山表层土壤中有机氯农药(OCPs)和多氯联苯(PCBs)总体上污染较轻,但高于一些其他地区。表层土壤的OCPs和PCBs表现出明显的随海拔高度增大的趋势,初步显示了高山冷凝捕集效应的影响。长白山旅游地区表层土壤受到轻微HCHs和DDTs的污染(平均值分别为12.4 ng/g和12.3 ng/g)。长白山附近较低海拔地区表层土壤中OCPs含量要略高一些,表明农业活动逐渐增大。HCHs和DDTs都未超过国家土壤环境质量标准的一级,但个别地点DDTs可能对鸟类和土壤生物具有一定的潜在生态风险。不排除在个别采样点有林丹和三氯杀螨醇被使用的可能性。长白山及附近地区表层土壤样品中∑7PCBs含量为7.3～31.9ng/g,平均17.2 ng/g。PCBs污染主要集中在海拔1450 m和1800 m处。7种PCBs异构体的含量依次为:PCB 28>PCB 52>PCB 180>PCB 138>PCB 101>PCB 153>PCB 118。 |
| 关 键 词： | 长白山 表层土壤 有机氯农药 多氯联苯 高山冷凝效应 |

| Abstract: | Topsoils from an uncontaminated area of Changbai Mountain of Jilin province were generally less polluted by the organochlorine pesticides(OCPs) and polychlorinated biphenyls(PCBs),but it is more so than in other areas.The total concentrations of OCPs and PCBs in the topsoils showed a clear increasing trend with altitude,which can be interpreted as an Alpine condensation trap effect.Topsoil in the scenic spot of Changbai Mountain was slightly polluted by HCHs and DDTs(with each average value as of 12.4 ng/g ... |
