Abstract
The application of mineral magnetic concentration parameters (χLF, χARM 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 (χARM and SIRM). This is also the same for each of the PM10, PM2.5 and PM1.0 sizes. Of the three magnetic parameters, χARM displays the strongest correlation (r = 0.45; p <0.01; n = 35) values and is the most significant parameter, which is consistent with class sizes of each approach. In doing so, these associations indicate mineral magnetic associations have considerable potential as a particle size proxy for determining urban roadside particulate matter concentrations. Given the speed, low-cost and sensitivity of the measurements, this suggests magnetic techniques could be potentially used as an alternative and/or complementary technology for pilot particulate pollution investigations. Furthermore, in certain instances, it could be useful for examining linkages between respiratory health and particulate pollution and vehicle emissions.
