汽车排气管烟尘磁化率对昆明地区公路边土壤磁化率污染关系的研究

The research of the relation between Automobile exhaust pipe smoke susceptibility and contamination susceptibility of soil in side of the road in Kunming

利用环境磁学方法对汽车排气管烟尘6个样品磁化率研究发现,汽车排气管汽油烟尘低频磁化率值为302.9×10-8m3/kg,柴油烟尘低频磁化率值为42.6×10-8m3/kg,远低于昆明地区公路两侧污染土壤的磁化率值。烟尘与土壤混合样品及汽车车身尘土样品研究表明,汽车排气管烟尘及车身对昆明地区公路边土壤的磁化率值不存在直接贡献值,同时对土壤的污染没有直接相关关系。

Methods for environmental magnetic ear exhaust pipe smoke in six samples susceptibility study found that ear exhaust pipe gasoline fumes low frequency magnetic susceptibility is 302.9 × l0^-8m^3/kg,diesel soot low-frequency magnetic susceptibility is 42.6x10^-8m^3/kg, far below the road on both sides of contaminated soil magnetic susceptibility values in Kunming.Soot mixed with soil samples and auto body dust sample studies show that smoke and car exhaust pipe body of the magnetic susceptibility of soil in side of the road in Kunming direct contribution to the value does not exist,while the contaminated soil is not directly related to the relationship.
