- The soot has been in Port Harcourt for over two years
Lagos, Nigeria (CNN)For more than two years, Saatah Nubari has woken up covered in a strange black soot.
There's been a literal cloud hanging over the southeastern city of Port Harcourt, Nigeria. People's clothes have been covered in soot. The streets are covered in soot. Even residents' bed sheets are covered in soot.
"You're wiping your face with a handkerchief and everything is black. You're trying to clean your car and everything is black. Or you look at the soles of your feet and it is just pitch black," said Nubari, an environmental activist in Port Harcourt, Nigeria.
For the local people of Port Harcourt the soot is inescapable. It's made life hellish for residents.
"It's had a wide range of impact on many things," said 25-year-old local resident Ebenezar Wikina.
The region isn't unfamiliar to plumes of pollution. The Niger Delta is the country's oil producing region and there are many oil refineries nearby.
However in the last few years, the situation has gotten much worse.
What causes the soot?
"Towards the end of 2015 it started, it wasn't this bad. People were complaining. But from between last year and this year, it has become much worse," said Nubari.
The cause of the soot has been something of a mystery. Although Nubari, like many activists and residents, believe it is a result of the destruction of illegal oil refineries.
"One of the causes is destroying products that are gotten from illegal crude refineries. When you burn them, it goes up into the atmosphere," said Nubari.
