Identification and verification of ultrafine particle affinity zones in urban neighbourhoods: Sample design and data pre-processing

Abstract

A methodology is presented and validated through which long-term fixed site air quality measurements are used to characterise and remove temporal signals in sample-based measurements which have good spatial coverage but poor temporal resolution. The work has been carried out specifically to provide a spatial dataset of atmospheric ultrafine particle (UFP < 100 nm) data for ongoing epidemiologic cohort analysis but the method is readily transferable to wider epidemiologic investigations and research into the health effects of other pollutant species. © 2009 Harris et al; licensee BioMed Central Ltd.
