The magnetic properties of street dust in the north and south of Baghdad, Iraq, have been studied. Fifty soil samples have been collected from heavily Traffic streets. Mass-specific magnetic susceptibility (χ), frequency-dependent susceptibility (χfd%), anhysteretic remanent magnetization (χarm), saturation isothermal remanent magnetization (SIRM), and thermomagnetic analyses were investigated. Mass-specific magnetic susceptibility (χ) is 72.86 × 10-8 m3kg-1 and 98.31 × 10-8 m3kg-1 for northern Baghdad (BN) and southern Baghdad (BR) (mean values), respectively. χ is well correlated with χarm with correlation coefficients (R2) of 0.96 and 0.83 for BN and BR, respectively. Grain size analyses show the existence of single-domain (SD) magnetite and maybe a small portion or absence of superparamagnetic (SP) grains in the samples. Thermomagnetic analyses clearly show a dramatic drop in the curve around 580°C during heating, which is the Curie temperature of magnetite. Results of concentration-dependent parameters, grain size, coercivity, and thermomagnetic analyses show the dominance of a soft magnetic phase like magnetite and the existence of a hard magnetic phase like hematite or goethite.
