Influence of vehicular traffic on a major trunk road on rural air quality in UK

Monthly data of particulate deposits were monitored at roadsides, 50 m and 100 m distance in proximity to the A49 trunk road over a 22-month period (June 2008-Apr 2010). Direct analysis by SEM-EDS, ICP-MS, PTrak and XRF revealed a seasonal, intra-and inter-site variations and a distance-decay relationship. However, at some locations with increased vehicular activities, this relationship was altered.
