由于有机物的不完全燃烧而产生的多环芳烃进入土壤，导致土壤中多环芳烃的含量上升，所以多环芳烃成为了土壤中主要污染有机物之一。本次实验主要针对土壤中污染的多环芳烃，通过测定得到多环芳烃的土壤污染的分布状况。
本次实验采用Agilent6890GC—5973NMS气相色谱-质谱联用仪，对自然保护区、工厂附近、农田和居民区中的土壤进行了测定，通过用样品质谱与预期化合物的标准质谱相比较对样品进行定性分析，用特征离子的EICP的面积分度值进行定量分析，从而得到样品的有关数据。
通过对自然保护区、工厂附近、农田和居民区所得到的土壤中多环芳烃的数据的比较可以看出：工厂附近土壤中的多环芳烃的含量要远远高于农田、居民区和自然保护区，并且离工厂越近的土壤污染程度也越严重。农田中因为农药的污染，所以多环芳烃的含量要大于居民区和自然保护区，自然保护区因为少有人为污染，所以土壤也相对最为纯净。

Many rings aromatic hydrocarbon produced because of the not totally burning of organic matter enters soil, lead to the fact soil many ring content of aromatic hydrocarbon rise, so many ring aromatic hydrocarbon become soil mainly pollute one of the organic matter. Experiment this directed primarily to soil many ring aromatic hydrocarbon of pollution, through determine, get many ring distribution state of soil pollution of aromatic hydrocarbon.
This experiment adopts Agilent6890GC-5973NMS gaseous phase chromatogram - mass spectrum to unite the appearance of using, have determined the soil in nature reserve, nearby of factory, farmland and residential block, through compare with, go on qualitative analysis with sample mass spectrum with standard mass spectrum to expect compound to sample, carry on quantitative analysis with the graduation value of area of EICP of the characteristic ion, thus get the relevant data of the sample.
Through to nature reserve, factory nearby, far
