Road dust sampling tests

Road dust sediments from the pavement of two active traffic lanes in the parish of Parque of Nações (Lisbon, Portugal) were vacuumed. Samples were collected at Alameda dos Oceanos street (GALP) on 30 May and 6 June 2023 and at Alameda dos Oceanos street (Abelhinhas) on 31 May and 6 June 2023. Both traffic lanes have asphalt, which is the predominant type of pavement existing in Lisbon. The measurements were carried out to assess the effect of the traffic light location and the street sweeping and washing.
