A database released by the World Health Organisation, WHO, indicates that Onitsha in Anambra state, Eastern Nigeria, is the most polluted city in the world.
According to the
report published by the World Economic Forum, WEF, “Of the 3,000 cities in the
WHO’s air quality database, the most polluted at the time of measurement was
Onitsha, a fast-growing city in Nigeria, which recorded roughly 30 times more
than the WHO’s recommended levels of PM10 particles.
“Onitsha is number one
because ‘it produced pollution levels of nearly 600 micrograms per cubic metre
of PM10s – around 30 times the WHO recommended level of 20 micrograms per cubic
metre.’
Three other Nigerian
cities, Aba, Kaduna and Umuahia, were featured in the top 20.
