La République du Sénégal est un exemple pour l'Afrique, pour être le pays avec le plus de transparence sur sa qualité de l'air. L'information Qualité de l'air est disponible publiquement et librement, une fois par jour à partir du site web de air-dakar.org.

Malheureusement, il y a trois problèmes qui nous empêchent d'afficher les données pour Dakar sur notre carte comme les autres pays:
  • Les données sont fournies qu'une fois par jour, alors qu'il est disponible pour toutes les heures pour d'autres pays.
  • La valeur de l'IQA (Indice de la Qualitée de l'Air) n'est pas disponible: seulement 4 niveaux sont fournis (bon, Moyen, Mauvais, Très Mauvais).
  • Les données individuelles, pour chaque polluants (PM2.5, PM10, Ozone...) ne sont pas disponibles.
Il existe de nombreux rapport de recherche sur la pollution au Senegal et plus particulirement a Dakar, par example:
  • Caractérisation physico-chimique de la pollution atmosphérique urbaine en Afrique de l’Ouest et étude d’impact sur la santé: raport par El Hadji Thierno Doumbia.
  • Caractérisation physicochimique et étude des effets toxiques sur des cellules pulmonaires des polluants particulaires de la ville de Dakar: rapport par Denis Dieme.
  • Memoire de Master sur la Pollution de l'air a Dakar: rapport par Claire Demay.
Dans ces rapports, il est clair que la pollution astmopherique a Dakar existe, et plus particulierment que, pendant la saison seche, les niveaux de pollution au PM2.5 sont frequement 'Mauvais' (Unhealthy, AQI 150 a 200), voir meme tres Mauvais (AQI > 200) - et ceci en dehors des episodes de poussiere....


L'evolution de l'AQI sur 4 années (graphe ci-dessou) confirme cette hypothese. Notez que ci le graphe ci-dessous prenait en compte les poussieres fines (PM2.5) et non pas seulement les grosses poussieres (PM10), alors l'indice serait probablement encore plus mauvais (explications).

The Republic of Senegal is a leading example for Africa, for being the country with the most transparency on its Air Quality. The Air Quality information is available publically and freely, once a day from the from air-dakar.org website.

Unfortunately, there are three problems which prevents us from displaying it on the map like other countries:
  • Data is provided only once a day, while it is available for every hour for other countries.

  • AQI value from 0 to 500 is not available. Instead, only 4 levels are provided (good, moderate, unhealyhy and very unhealthy) without much information about the dominent pollutants and thresholds.

  • Detailled readings, for each pollutants and expressed in mg/m3 is not available.
For more information about the Dakar Air Quality Monitoring Center, check those slides presented at the Africa Sustainable Transport Forum (ASTF) on 28 to 30 October 2014.

About the Air Quality Levels

AQIAir Pollution LevelHealth ImplicationsCautionary Statement (for PM2.5)
0 - 50 Good Air quality is considered satisfactory, and air pollution poses little or no risk None
51 -100 Moderate Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
101-150 Unhealthy for Sensitive Groups Members of sensitive groups may experience health effects. The general public is not likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
151-200 Unhealthy Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
201-300 Very Unhealthy Health warnings of emergency conditions. The entire population is more likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
300+ Hazardous Health alert: everyone may experience more serious health effects Everyone should avoid all outdoor exertion
