The environmental noise pollution in Lagos State has an impact on the quality of life and it is a serious health and social problem. The focus of this article is to assess the sources and noise levels, and possible impacts in selected urban environmental are of Lagos
Lagos state is a huge metropolis which originated on islands separated by creeks such as Lagos Island that fringe the southwest mouth of Lagos Lagoon protected from the Atlantic Ocean by long sand spits such as Bar Beach which stretch up to 100 km east and west of the mouth. Lagos was originally inhabited by the Awori subgroup of the Yoruba People. Under the leadership of their Olofin, the Awori moved to an island now called Iddo and then to the larger Lagos Island.
Lagos is the smallest state in Nigeria in terms of land area but the second most populous state and arguably the economically important state of Nigeria. The urban environmental noise pollution simply entails all that makes the urban centre not to be conducive for living and also makes the environment to be unhealthy for a living.
In spite of the extensive generation of noise in urban areas of Nigeria, surprisingly little research and documentation exist on the nature and extent of noise generation activities, their accompanying impacts and the implication for urban communities and their residents. In recent years, noise has been identified in the developed countries as a regrettable but necessary fact of city life.
The above observation is no less true of Nigerian urban life. Increasingly, urban noise is getting louder and more pervasive, prompting public comments and few noise abatement regulations. It has observed however that these regulations have failed to curb noise. Noise is also seen as a sound which is not wanted by the recipients, it is clear that what may be a pleasant and enjoyable sound to one person may not be to another person.
Sources and Causes of Noise Pollution in Lagos Environmental Areas
The various sources of noise pollution in Lagos environmental area may be grouped into various categories
– Road Traffic
– Industrial Activities
– Entertaining Activities
Effects of Noise on the Residents of Lagos State
– Disturbance to Sleep: It has been argued by a scholar that a general bodily reaction to noise often contributes to feelings of fatigues, irritability, or tension. Disturbance to sleep can, in turn, result in muscular tension, diminished work effectiveness, and slower reaction time.
– Interference with Communication and Productivity: Noise has been established to be an unambiguously interferes with both communication and productivity. Amongst the specific disorder reportedly suffered from exposure to noise were a headache, lack of concentration, dizziness, and nervousness.
– Cardiovascular and Gastric Impact: A practitioner has found out that sudden noise automatically causes constriction of peripheral blood vessels (in toes, fingers, and abdominal muscles). Sometimes, noise pollution can cause dilation of blood vessels in the retina and the brain. Marked gastric alteration similarly occurs on exposure to sudden and unexpected noise.
– Hearing Loss: Another practitioner has also asserted that noise impairs people hearing. He explains that a medical examination of anyone who is continuously exposed to sounds like those coming from car-horns, loud speakers, and air crafts will show that the person will definitely have impaired hearing.
