Magnetic measurement was combined with geochemical analysis to investigate the trace metal pollution of PM<sub>2.5</sub>. The study was carried out in Nanjing, China, where the average PM<sub>2.5</sub> concentrations in summer and winter in 2013-2014 were 66.37 and 96.92 μg/m<sup>3</sup>, respectively. The dominant magnetic mineral in PM<sub>2.5</sub> had a low-coercivity pseudo-single domain and consisted of magnetite and hematite. Iron-oxide magnetic particles comprised spherical as well as an ...[more]
