or Munktell MK360 quartz ﬁlters (ØD90mm, Maidstone, UK) and weighed by the giant gravimetric balance method (Yang et al., 2015). Different ﬁlters were chosen depending on target analytes, e.g., the analysis of Si and water soluble inorganic ions must be performed with Teﬂon ﬁlters, while quartz ﬁlters should be used for OC and EC

The PM 2.5 samples were collected onto Whatman 3–5 Teflon membrane filters (Ø = 47 mm, Maidstone, UK) or Munktell MK360 quartz filters (Ø = 90 mm, Maidstone, UK) and weighed by the giant gravimetric balance method (Yang et al., 2015).

Each sampler was loaded with 15 filters of one type, 7 of which field blanks, and was Another sampler (Sierra Andersen HV) equipped with a PM10 inlet collected the aerosol on Munktell MK 360 quartz fibre filters with a filter face velocity of 0.5 m s −1. All these samplers operated on a 24-h schedule to collect adequate deposit masses for chemical analysis and also to ensure to follow common procedures of air monitoring networks.

Micro-quartz filters are useful for testing hot stack gases as the quartz fibers can withstand temperatures up to 900 °C. In addition, micro-quartz is used when the highest purity media is required. With excellent filtration properties and minimal traces of metals and minerals, quartz fibers are dimensionally stable and can be used in the analysis of acidic gases with the exception of Particulate matter was continuously collected on quartz fiber filters (Munktell MK360, 15 cm diameter) using a high-volume sampler (Digitel) without an upper cut-off and by low-pressure impactors (Berner type; with polyvinylfluoride as sampling substrates for ions and mass and aluminium foils as sampling substrate for carbon analysis) covering 6 QMA plugs (Whatman) + 7 MK360 plugs (Munktell) + 3 C18 plugs (Empore) Alexandre.
