Atmospheric concentration of PM10 elements (including REEs) measured in Tunisian desertic region

Air concentration of elements collected near Medenine, Tunisia, during a two weeks field campaing from March 29th to April 7th 2016, and using two different sampling head: a newly designed stainless steel decanter, VTD, and a brand-new aluminium alloy commercial PM10 sampling head, both operating at a flow rate of about 1 m3 h−1. A total of 16 paired samples were collected during a 2-week field experiment, at the Institut des Régions Arides campus, 20 km north of the city of Medenine, Tunisia.

The collection site (33°29'58.62′′ N – 10°38′35.2′′ E), surrounded by dry lands, is 5 km south-west of the Boughrara Gulf. The two sampling devices were fixed to the roof of the highest building on campus (about 20 m). Both the VTD and PM10 were attached to a tubular stand, with a distance of about 30 cm between them.
