Biomagnetic monitoring has shown to be a promising approach to capture spatio-temporal variation of particulate air pollution, yet lacking information on source-dependent magnetizable composition and health-relevancy of atmospheric particles impedes its general application in air quality assessments. This ongoing PMF project addresses this knowledge gap by evaluating atmospheric PM originating from different sources (road and railway traffic, shipping, industry) for its chemical composition, association with related pollutants, magnetic properties and early health response of human lung cells, combining a range of sampling and analytical techniques. This research hereby contributes to source “fingerprinting” and its potential for source attribution in urban areas, and to assess the health-relevancy of biomagnetic monitoring.
