Statement
PM10 samples have been collected since February 2006 using a home made high-volume (Hi-Vol) system running at 30m3 h-1 behind a DIGITEL PM10 pre-separator DPM10/30/00. Substrates are quartz-fiber filters (PALL, 15 cm Ø) prefired at 800 °C°C for 1 h. PM1 samples were collected using a low-volume system. The 1 µ m cut-off was provided by a Digitel DPM10/01/01/0 head at a flow rate of 1m3 h-1 kept constant by a vacuum pump behind a critical orifice. Substrates were pre-fired 47mm quartz-fiber-filters (Whatman). We discuss here the results from the 43 samples collected in the first year of measurements, from February 2007 to February 2008. Daytime PM1 samples were collected from 13:00 to 18:00 (local time) over three contiguous days, while night-time samples were collected from 22:00 to 06:00 over nine consecutive nights. The long sampling time is necessary given the low sampling flow and the low concentrations typically found during the night.
