The aim of this study was a detailed chemical characterisation of the particles released during the preparation of popular Portuguese dishes. PM samples were collected from the exhaust stacks on the roofs of a university canteen, a charcoal-grilled chicken restaurant and a wood-oven roasted piglet restaurant. The speciation of organic compounds was carried out by gas chromatography-mass spectrometry.

Particulate matter (PM, PM and PM) and total volatile organic compounds (TVOCs) were continuously measured. Passive tubes for carbonyls and a high volume PM sampler were simultaneously used.

Given the dearth of studies on the variability of road dust, in the present study, an in-situ resuspension chamber was used to collect PM samples from seven representative streets in Viana do Castelo, the northernmost coastal city in Portugal. PM samples were analysed for organic and elemental carbon by a thermo-optical technique, elemental composition by ICP-MS and ICP-AES, and organic constituents by GC-MS.
