PARTICULATE AIR POLLUTION AND ITS HEALTH IMPLICATIONS ON PEOPLE IN PUBLIC PLACES ALONG EAST-WEST ROAD, RIVERS STATE NIGERIA

Background: Globally, air pollution is a public health emergency that affects people of different ages. This study assessed and determined the level of particulate air pollution and its health implications on people in public places along East-West Road in Obio-Akpor LGA, Rivers State. Methods This study was conducted in public places along East-West Road, Rivers State. An analytical cross-sectional study design was used for this study. A potable digital handheld air monitor was used to measure air particulate pollution. A real-time multi-channel particle monitor was used for aerosol profiling (Aerocet 531S Met One High Volume sampler). An interviewer guide was used to assess the health implication of air particulate pollution. We sought and got ethical clearance for the study from the Research and Ethics Committee of the University of Port Harcourt. Consent was obtained from the participants in the sampled locations where measurements were taken. Results: Unhealthy concentrations of PM2.5 and PM10 were observed in all study locations. While the concentration of PM10 was significantly higher during the dry season in all study sites, same was observed in only two locations (NK & MK) for PM2.5. There were significant associations between high levels of PM2.5 and reported symptom related to respiratory and dermatological dysfunction. Conclusion: Study reported unhealthy levels of particulate matter in ambient air in all locations with significant variations between seasons as well as significant association with respiratory and dermatological symptoms. There is a need to create awareness among the population of the potential risk of pollution from particulate matter to instigate focused and coordinated actions that would lead to reduction in the level of particulate matter in ambient air as well as reduce exposure to these pollutants and its associated health issues.
