Lagos State, Nigeria’s commercial capital and most populous state, has been ranked 133 in the world’s most polluted cities (historical data 2017-2022), according to a report by IQAir.
In its 2022 World Air Quality Report on most polluted city ranking which, according to IQAir, is based on annual average PM2.5 concentration (μg/m³), Lagos was said to be “experiencing some rather poor quality air with a US AQI figure of 160 which classified it as ‘unhealthy’ according to recommended figures from the World Health Organisation” at the beginning of 2021.
Lagos, with an estimated population of the metropolitan area was 21 million people as of 2018, has the concentration of its PM2.5 pollutant as 73.2 µg/m³.
“With a level such as this,” the report says, “it is recommended that a good quality mask is worn when going outside. Doors and windows should be kept closed so as to prevent the ingress of polluted air in the home. All types of outdoor exercise should be abandoned until air quality improves.”
