| Description du jeu de données | |||
| Résumé | VOCs were collected on sorbent tubes in the coastal city of Abidjan, Côte d’Ivoire, in winter and summer 2016 and later analysed by gas chromatography coupled with flame ionization and mass spectrometer detectors (GC-FID and GC-MS) in a laboratory. | ||
| Strategie d'observation | The field campaigns were conducted in Abidjan, Côte d’Ivoire during summer and winter 2015 and 2016 according to the strategic directions of the DACCIWA WP2. Cartridges deployed for VOC measurements were composed of Tenax TA 60-80 mesh (250 mg) or Carbopack C (150 mg). The combination of both sorbent materials allowed the sampling of 10 aromatics (C6-C9), 22 n-alkanes (C5-C16), 10 monoterpenes, 7 aldehydes, isoprene, and other oxygenated compounds. Samples were collected every 2 days at different times of the day (from 6 a.m. to 8 p.m.) by using a manual pump (Accuro 2000, Dräger) at 100 sccm (standard cubic centimetres per minute) flow rate. One single sorbent tube was exposed six times at each sampling location. In total, 3.6 L of air were collected at each site for a single 600 mL-volume each time. Before the sampling, multi-sorbent filled cartridges were conditioned by flowing purified nitrogen through them, at a rate of 100 mL min-1, for 5 hours at 320°C. | ||
