11 Worst Countries for Air Pollution

9. Senegal

Average PM2.5 pollution: 40 ug/m3

Average PM10 pollution: 179 ug/m3

Senegal may be a small country, ranking 87^th in the world (the latest estimate indicating 13.5 million people), but it has a serious problem with pollution. The country is an example among African nations when it comes to its transparency about Air Quality levels, which is commendable, but the data isn’t reported like in other nations around the globe. For instance, they only hand out data once a day, instead of every hour, and the pollutants aren’t expressed in mg/m3, but rather on estimate levels – good, moderate, unhealthy, and very unhealthy.

The country’s government has been trying to implement a campaign against pollution, but it’s going to take time before we see any results.
