The traffic station in Msida (35.90°N, 14.49°E, 2m AMSL), located in the Maltese archipelago (in the Central Mediterranean) forms part of the Maltese air quality network. PM2,5 levels have been monitored at this site since 2008 and have been reported to the European Commission ever since. The receptor is within 10 m of an important traffic node with flows of ~23000 AADT which links Malta's administrative capital (Valletta) to the main Commercial, Entertainment and Tourism hub (Sliema). Additionally the site is surrounded by heavily trafficked areas to both the north and south, including Malta's busiest traffic artery (~41000 AADT) at 2.5 km to the SSE. PM2,5 levels at the receptor are expected to be heavily influenced by traffic. Other contributors to PM2,5 levels are expected to be shipping (due to the presence of a busy shipping lane to the east of the receptor) but also natural sources such as Saharan dust and sea salt. The objective of this study is to isolate and quantify the traffic aerosol source contributions to the PM2,5 levels in Msida. Traffic emissions are Malta's major air quality concern and it is expected that the conclusions of this study will help the policy maker to take the required action. The sampling campaign ran from 01 January 2016 to 31 December 2016, for a total of three hundred and sixty six samples collected on 46.2 mm Teflon filters and every two days on 47 mm quartz fibre filters at a flow rate of 2,3 m3/h. The filters were conditioned, prior to weighing, for 96 h at a relative humidity range >45% and < 50% and at a temperature of 20°C±1°C. A sample of 180 Teflon filters were chosen in such a way that the seasonal weekday and weekend averages were as close as possible to those of the full population of filters. The ratio of weekday : weekend filters was kept at 2.5. The filters were analysed non-destructively for black carbon (BC) using a multi-wavelength absorbance analyse. Subsequently the same filters were analysed for 17 different elements (Al, Si, Cl, K, Ca, Ti, V, Cr, ... |
