fibre filters Munktell type MK360 were used for sampling. The grade MK360 filters ability of catching 0.3 µm particles is better than 99.998%. Preparation of filter sets was carried out at the laboratory. Filters were heated up to 160 °C for the removal of organic impurities at first. Before and the use of quartz filter (Munktell MK360, 25mm) instead of the PTFE (Polytetrafluoroethylene) filters indicated by the sampling method, due to their better extractability and higher cleanliness which allowed fully benefitting of the GC/MS (Gas Chromatography- Mass Spectrometry) analytical method adopted. The sampling (Munktell, type MK360, ϕ = 81 mm). Each set of samples was continuously collected for 48 or 24 h, depending on the Air Pollution Prediction Index provided by the local government.

Type MK 360/T 293. 50 mm. Pure quartz micro- fibre without glass fibre and binder. Emission control up. filter (Munktell MK 360), of 7 mm diameter is housed in a quarts glass tube of 140 mm length. The micro-fibre filter is supported by a pure Ni-screen.

Routine sampling was conducted for 48 h from 10:00 (local time) on Monday to 10:00 on Wednesday every week. Intensive sampling intervals of 24 h were also performed to 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).
