The government have adopted a standard(1) related to the atmospheric pollution surveillance, and that standard precise that the mesures will be done by quaterly. But there is no evidence that the mesures are effectively done. For the city of dakar, there is a website where polluttants data are published(2). 1. 2.

add by Reviewer now seem the data is Measured the last data is from 02 octobre 2015 its stil not Is provided on a timely and up to date basis of a week 4,and the Detailled readings, for each pollutants and expressed in mg/m3 is not available. Instead, only 4 levels are provided (good, moderate, unhealyhy and very unhealthy) without much information about the dominent pollutants and thresholds. also it seem the data is only for the city of dakar
