Port Harcourt
Air Pollution

Residents of the city have been experiencing particle (soot) pollution since the last quarter of 2016. Residents state their clothes and everything outside is covered with a layer of black soot. Official PM2.5 information from the state's environmental commissioner, Roseline Konya, states a high reading of 270 micrograms per cubic meter for air pollution in the city from a 2016 sampling. According to the U.S. Environmental Protection Agency's (EPA) index air quality index (AQI), a reading of 0 – 50 is good, readings between 200 – 300 which Port Harcourt falls under is considered unhealthy for everyone and E.P.A advises residents of such areas to avoid heavy and prolonged exertion, and move activities indoors. "For a 15-month period ending in June... air quality was in the unhealthy range on 240 days, with 85 days ranking very unhealthy, and 13 days as hazardous."

The increased deterioration of ambient air quality led to a state protest in February 2017. There were experiences of black soot settling in nostrils, on cars, floors, roofs, windows, bathtubs, bathroom, kitchen sinks and household furniture surfaces resulting in frequent cleaning of affected surfaces and places. potable, domestic and rainwater were equally affected. Abuloma, Iwofe, Rupokwu, Okrika, and Woji were mostly affected with other areas such as Rumuigbo, Eleme, and Oyigbo Local Government Councils, as well as Ogoni.

The covering of the haze of soot in most parts of the city have resulted in visibility impairment by PM2.5, soil, and water deposition, and disruption in ecosystem diversity. This also made the city dwellers to spend more time indoors than outdoors. Residents in cities such as Rumosi and Rumuodumanya in Obio/Akpor Council have relocated to other safe cities leading to decline in business activities.

The Ministry of Environment took action by analysing air samples from various sites in the city and found out to be 11 times higher than WHO specifications for PM2.5 and PM10. This non-compliance was tackled by shutting down the Chinese Government Company (CGC), H&H Engineering Company, and AUC Asphalt Company located in Aluu community, found to be the location of high volume discharge of emissions thereby contravening environmental regulations. Illegal refineries, burning of tires, gas flaring, liquefied natural gas (LNG) operations and processes, petro-chemical companies, and refineries were other suspected sources of soot pollution.
