| 摘 要： | 镉是一种毒性很大、在自然界中分布广泛的重金属元素。利用辽河流域生态地球化学调查中取得的土壤、大气干湿沉降、灌溉水及农药化肥等样品，对沈阳细河地区土壤中镉污染源进行了甄别及追踪。结果表明: 沈阳细河地区土壤中镉元素污染是由人为源引起，且镉元素污染源主要为污水灌溉、大气降尘及磷肥三种途径。

| Abstract: | Cadmium is a kind of heavy metal elements which has high toxicity and distributes widely in nature. According to the samples of soil, atmospheric dry and wet deposition, irrigation water and pesticides, the authors identified and pursued cadmium pollution source in soil of Xihe area of Shenyang. Results showed that cadmium pollution in soil of Xihe area was produced by artificial source, caused mainly by sewage irrigation, atmospheric deposition and phosphorus fertilizer. |
