| 摘 要： | 采集了黑龙江省松嫩平原南部大气降尘样品,以农村、城镇、城市为单元对降尘通量与指标含量特征进行了探讨。对大气降尘中20种指标含量的分析结果表明:与土壤背景值相比较,Hg、Cd含量在大气降尘中显著富集;以A l为参考元素计算表明,Cd、S明显受人类活动影响而具有较大的富集因子;主成分分析各指标的主要来源为人类活动、地表尘土与人类活动叠加、区域扬尘。

| Abstract: | According to the sampling of atmospheric dust fall in southern Songnen Plain,the features of dust flux and indicators are discussed in this paper with the countryside,town,and city as the unit.The content levels of 20 kinds of indicators in the atmospheric dust samples were studied.The results show that,compared with the soil background values,Hg and Cd in the atmospheric dust are significantly concentrated.With Al element as a reference,the calculation results show that Cd and S elements are significantly ... |
