Onitsha, a city in Anambra state, Nigeria, has been labelled the world's most polluted city by the World Health Organization (WHO) in 2016. The city recorded 30 times more than the WHO's recommended levels of particulate matter concentration (PM10). Onitsha's air pollution is caused by a variety of factors, including cooking fires, burning waste, traffic pollution from old cars, and industrial activity. The city's government has been criticized for its ineffective waste disposal system and lack of regulation of air quality. Solid waste also litters the streets, blocking drainage systems and canals. While some residents are unaware of the health risks associated with pollution, others are preoccupied with more immediate concerns, such as providing for their families.

Onitsha, Nigeria, is the world's most polluted city
Onitsha, Nigeria, has been labelled the world's most polluted city by the World Health Organization (WHO). The city recorded 30 times more than the WHO's recommended levels of particulate matter concentration (PM10). Onitsha is a booming port city in southern Nigeria, with a population of over 100,000. It is famous for its river port and serves as a regional hub for trade and logistics in Eastern Nigeria.
According to the WHO report, the main sources of pollution in Onitsha are the use of solid fuels for cooking, burning waste, and traffic pollution from old cars. The city's economic growth and urban expansion have also contributed to the pollution problem. The air in Onitsha is thick with toxic pollutants, and the streets are littered with solid waste, blocking drainage systems. The Nigerian government and health authorities have been criticised for failing to effectively tackle the environmental pollution crisis.
The effects of the high levels of pollution on the health of Onitsha's residents are concerning. According to the United Nations Environment Programme (UNEP), around 600,000 deaths in Africa each year are associated with air pollution. However, many residents of Onitsha are unaware of the dangers or are more concerned with immediate needs, such as feeding their families. Some have simply become accustomed to living in a polluted environment.
Community initiatives, such as trash clean-up drives, have emerged in Onitsha to address the waste issues. However, without significant government intervention and regulation, the city continues to struggle with the devastating impacts of pollution. The story of Onitsha highlights the urgent need for action to improve air quality and protect the health of vulnerable communities in Nigeria and beyond.

Air pollution in Onitsha is 30 times the WHO's recommended levels
Onitsha, a city in Anambra state, Nigeria, has been labelled the world's most polluted city by the World Health Organization (WHO). The city recorded thirty times more than the WHO's recommended levels of small and fine particulate matter (PM10). The high levels of pollution in Onitsha are due to a combination of factors, including the reliance on solid fuels for cooking, burning waste, traffic pollution from old cars, and unregulated car emissions.
The city of Onitsha is located on the eastern bank of the Niger River and is known for its river port, which serves as an economic hub for commerce, education, and industry. The booming port city's economic growth and urban expansion have contributed to the increase in pollution levels over time.
The air in Onitsha is thick with toxic pollutants, and the streets are often clogged with solid waste, blocking drainage systems and canals. The health risks associated with exposure to high levels of PM10 are well-known, including respiratory issues and cardiovascular problems. However, many residents of Onitsha are unaware of the dangerous levels of pollution or are preoccupied with meeting their basic needs, such as feeding their families.
The Nigerian government and local authorities have been criticised for their lack of action in addressing the environmental pollution in Onitsha. The now-defunct Anambra State Environmental Protection Agency was widely criticised for its failure to tackle the issue effectively. While some residents have taken it upon themselves to organise trash clean-up initiatives, sustained efforts from the government and collective action are necessary to address the air pollution crisis in Onitsha.

Onitsha's pollution is caused by cooking fires, burning waste, and old cars
Onitsha, a booming port city in southern Nigeria, has been labelled the world's most polluted city for air quality. The city recorded PM10 levels that were 30 times higher than the recommended levels set by the World Health Organisation (WHO).
Onitsha's pollution is caused by a variety of factors, including cooking fires, burning waste, and old cars. Cooking fires and burning rubbish have contributed to the city's record-setting levels of air particulates. According to WHO measurements made in 2016, the city recorded the world's worst levels of PM10 air pollution. Approaching the Okpoko market, one is enveloped in thick smog, and the natural reaction is to cover your nose to protect yourself from the dust storm.
The city also struggles with solid waste littering the streets, blocking drainage systems and canals. With no waste bins in sight, unregulated rubbish dumps occupy roadsides and street corners. The state government has been criticised for its ineffective management of the waste disposal system, and the now-defunct Anambra State Environmental Protection Agency was widely condemned for failing to address environmental pollution.
Traffic pollution from old cars also contributes to Onitsha's poor air quality. Unregulated car emissions and the use of generators due to unreliable electricity supplies further exacerbate the problem. Nigeria's rapid economic development and industrial growth have led to increasing pollution levels, as noted by Dr Maria Neira, WHO Director of the Department of Public Health, Environmental and Social Determinants of Health.
The health effects of sustained exposure to high levels of PM2.5s are well-proven, and around 600,000 deaths in Africa each year are associated with air pollution, according to the United Nations Environment Programme (UNEP). However, some residents of Onitsha are unaware or unconcerned about the dangerous levels of pollution, and the government's efforts to improve the situation have been limited.

The Niger River and Niger Bridge define Onitsha's location
Onitsha, a port city in southern Nigeria, is located on the eastern bank of the Niger River, which is the third-longest river in Africa. The Niger River Bridge, also known as the Onitsha Bridge, was constructed between 1964 and 1965 by the French construction company Dumez. The bridge, which has two lanes and a pedestrian walkway, connects Onitsha in Anambra State to Asaba in Delta State. It serves as a major road connection and is part of the Trans-African Highway between Lagos and Mombasa, Kenya, as well as the main east-west connection within Nigeria.
The Niger River Bridge has played a significant role in the history of Onitsha and Nigeria. During the Nigerian Civil War from 1967 to 1970, retreating Biafran soldiers destroyed the bridge in an attempt to halt the Nigerian military advance. Despite this destruction, the bridge was repaired and continued to serve as a vital link between the two regions. However, over time, the bridge became congested with traffic and informal traders, highlighting the need for additional infrastructure.
To address the congestion and modernise the transport network, the construction of a second bridge, known as the Second Niger Bridge or the Second Onitsha Bridge, was proposed as early as the 1958/1959 political campaign. The project faced numerous delays and challenges, but it was finally inaugurated in 2023. The Second Niger Bridge is part of a new motorway ring designed to minimise traffic congestion on the old bridge and enhance the region's connectivity.
The Niger River and the Niger Bridge are not only crucial for transportation but also play a significant role in Onitsha's economy and cultural identity. The river is a source of livelihood for many residents, with activities such as fishing and river trade contributing to the local economy. Additionally, the river's aesthetic value and the bridge's architectural significance have become symbols of the city, attracting tourists and showcasing the beauty of Onitsha and its surroundings.

Onitsha's government has failed to tackle environmental pollution
Onitsha, a city in Anambra state, Nigeria, has been labelled the world's most polluted city by the World Health Organisation (WHO). The city recorded PM10 levels that were 30 times the recommended amount, and PM2.5 levels that far exceeded safe limits. These dangerous levels of air pollution are caused by a variety of factors, including cooking fires, burning rubbish, sandstorms, vehicles, increased industrial activity, and traffic pollution from old cars.
Despite the severity of the situation, the Onitsha government has failed to tackle environmental pollution effectively. The now-defunct Anambra State Environmental Protection Agency was widely criticised for its inability to address the issue. Its replacement, the Anambra State Waste Management Agency, has also failed to bring about any significant change. The government's lack of response to the pollution crisis has been met with criticism and concern from residents and international organisations alike.
The impact of pollution on the health of Onitsha's residents is profound. According to the United Nations Environment Programme (UNEP), around 600,000 deaths in Africa each year are linked to air pollution. Additionally, an OECD report estimated that polluted air could be responsible for 712,000 premature deaths annually across the continent. Unfortunately, many residents of Onitsha are unaware of the dangers posed by the pollution or are preoccupied with more immediate concerns, such as providing for their families.
The city's waste disposal system is inadequate, with rubbish clogging streets, drainages, and canals. This solid waste problem is further exacerbated by the government's failure to provide waste bins or effective waste management solutions. The lack of official data on pollution levels in Onitsha makes it challenging to fully understand the extent of the problem and its impact on residents' health. However, the high concentrations of pollutants in the air, including small and fine particulate matter, are indisputable.
The government's inaction has led to a sense of resignation among some residents, who feel that their concerns are falling on deaf ears. This is evident in the story of Christopher Anaekwe, a local man who organised a neighbourhood clean-up initiative that went viral on social media. While Anaekwe's efforts are commendable, they also highlight the government's failure to address the waste issues plaguing the city. It is clear that Onitsha's government has fallen short in its responsibility to protect the health and well-being of its citizens from the detrimental effects of environmental pollution.
