| 摘 要： | 通过X射线衍射仪,确定了江油市河西乡附子中药材道地产地大气降尘的矿物组成为伊利石、绿泥石等,且主要来源于地面扬尘、大气光化合作用;运用富集因子法、潜在生态风险评价法对该区大气降尘中重元素的富集程度进行分析,表明其近地表大气降尘中重金属元素的污染较为严重。

| Abstract: | We used X-ray diffraction to determine the mineral composition of atmospheric dust from the Chinese herbal origin area in Jiangyou.It mainly came from the ground dust and atmospheric photochemical cooperation.We also used enrichment factor method and potential ecological risk assessment methods to analyze the enrichment of heavy elements in the area.The results indicated that the heavy metal pollution was more serious in near-surface atmospheric dust. |
