In 2015, the little Green information book detailed that the Nigerian populace is presented to elevated degrees of Particulate matter(PM) 2.5 which surpasses the ordinary norms/rules set by WHO at 94%, and it went further to express that 3% of kids under 5 years old experienced intense respiratory disease.

An air quality screen in Onitsha recorded 594 and 66 miniature life forms for each cubic meter of PM 10 and 2.5 separately. Albeit this data was respected not so dependable by WHO agent, as a result of the presence of only one single observing station in the city.
