Evaluation of Noise Pollution Levels in Selected Markets and Motor Parks in Delta State, Nigeria

Abstract

Background: The control of environmental noise pollution has been hampered by lack of sufficient knowledge of its effect on human. Noise pollution is associated with several health conditions and affects both health and behavior. This study evaluated the noise pollution level in selected market and motor parks in local government areas in Delta State. Methods: The physical parameters were measured using a digital sound level meter and a mobilebased global positioning system (GPS), in September 2021. To determine noise pollution all over the city, the noise measurements were collected in the morning and evening. The selected areas of the study were market places, road junctions/busy roads and passenger loading parks. The noise pollution levels were measured in Ogwashi-Uku Market, Ogwashi-Uku Motor Park, Nwasi Motor Park, Ibusa Market, Central Motor Park Asaba, Delta Line Park Asaba, Onitsha Park and Oko Market Asaba. Results: The results showed that the average pollution level in the morning hours were 89.33, 90.1, 90.3, 91.72, 86.59, 90.11, 92.15 and 90.3 dB in Ogwashi-Uku Market, Ogwashi-Uku Motor Park, Nwasi Motor Park, Ibusa Market, Central Motor Park Asaba, Delta Line Park Asaba, Onitsha Park and Oko market Asaba, respectively. In the evening, the corresponding measured values were 83.65, 74.90, 90.04, 90.90, 85.07, 83.44 and 91.79 dB respectively. These values were higher than the Federal Environmental Protection Agency (FEPA) and World Health Organization (WHO) standard limits for outdoor environment. Conclusion: The people who are working and living in the areas under study may be at risk of noise related health hazard due to continuous daily exposure.
