Application of mineral magnetic concentration measurements as a particle-size proxy for urban road deposited sediments

Reviewed papers accepted for the Seventeenth International Conference on Modelling, Monitoring and Management of Air Pollution held in Tallinn, Estonia in July 2009The application of mineral magnetic concentration parameters (��LF, ��ARM and SIRM) as a potential particle size proxy for urban road deposited sediment collected from Scunthorpe, North Lincolnshire, U.K. has been investigated. Correlation analyses between each magnetic parameter and traditional particle size classes (i.e. sand, silt and clay) and respiratory health related size classes (i.e. PM10, PM2.5 and PM1.0) are reported. Significant relationships (p <0.01; n = 35) exist between clay content and two of the magnetic concentration parameters (��ARM and SIRM). This is also the same for each of the PM10, PM2.5 and PM1.0 sizes. Of the three magnetic parameters, ��ARM displays the strongest correlation (r = 0.45; p
