| 摘 要： | 选择珠江三角洲地区某市为试区,采用GPS定位系统设了77个采样点,采用GC-MS法测定了菜地土壤中16种多氯联苯(PCBS)含量。除未检出PCB87、PCB138、PCB156、PCB194外,其他12种PCBs同系物均有不同程度的检出,检出率最高的是PCB101,残留量均值最高的是PCB128。空间分析发现,该研究区西北部和中部地区多氯联苯含量最高,这主要与当地的产业布局有关。 |
| 关 键 词： | 菜地土壤 多氯联苯(PCBs) 污染状况 |

| Abstract: | 77 vegetable soil samples were collected from typical area of Pearl River Delta using GPS positioning system and analyzed for concentrations of 16 kinds of polychlorinated biphenyls using GC-MS method.Except PCB87,PCB138,PCB156,PCB194,other PCBs were detected at different residue level.PCB128 showed the highest residue average value,and PCB101 had the highest occurrence.Spatial analysis showed that the highest PCB levels occurred in the northwest and central regions of this area,which was mainly related wit... |
