The magnetic properties and heavy metal contamination were used to test the relationship between the anthropogenic magnetic particles and heavy metals contents in samples of roadside soil and dust from service districts along G312 highways. The results show notable linear correlation between lf and SIRM. Also, low S-300mT values indicate that the ferrimagnetic minerals contribute more to SIRM, however, incomplete anti-ferromagnetic minerals account for low proportion. Low values of fd% and the ratios of ARM/SIRM, ARM/ show the existing of coarse- grained roadside soil and window sill dust. The roadside soils mainly contain single domain and multi-domain magnetic minerals, and the dusts multi-domain grain magnetic minerals. lf, SIRM, which are sensitive to ferrimagnetic minerals, appear similar variations with heavy metals Pb, Zn, Cu. Therefor, coarse-grained (multi- domain) ferrimagnetic minerals, which absorbed heavy metals, are the main pollutions in roadside soil and dust along G312 highways.
