Abstract

Particulate matter derived from various sources of fuel combustion contains minor to trace amounts of Fe-oxides that can be detected by magnetic measurements. These magnetic particulates can be used as proxies for particulate pollution, since oxide contents are often larger in amounts and may have distinctive magnetic properties, compared to most types of natural dusts. Magnetic particulates range in size from a few nanometres to 100s of microns. Magnetic measurements of sediment cores and soils therefore provide evidence for historical particulate pollution loads, both in time since ca. AD 1800, and the spatial expression of pollution loads
