The organic matter content of street dust in Liverpool, UK, is measured for five particle size fraction and bulk samples. The content decreases significantly with increasing size for fractions < 300 μm (in diameter), but the variation is not substantial for fractions > 300 μm. The magnetic measurements indicate that the dominant magnetic component is multidomain grains of ferrimagnetic minerals and that superparamagnetic and stable single domain ferrimagnetic grains and non-ferrimagnetic minerals are present in small magnetic concentrations. There is a close association between the organic matter content and frequency-dependent susceptibility (XFD percentage), with a significant correlation for < 63-μm fraction samples and a highly significant correlation for > 63-μm fraction and < 1000-μm bulk samples. The ratio χARM/SIRM shows a highly significant correlation with the organic matter content for < 150-μm fraction samples. This study suggests that simple, rapid, and non-destructive magnetic measurements could provide useful information about source apportionment of organic matter in street dust.
