Assessment of Determinant Sources of Plastics and Microplastics Pollution in Inland Waterways Navigation in Lower River Niger

This study was aimed at assessing the impact of plastics and micro plastics pollution in Nigerian inland waterways operations. The main aim of this study is to provide a baseline assessment of plastic pollution in the River Niger, along with recommendations for further research. Using a survey and appropriate data analysis tools, the study investigated the determinant sources of plastic pollution in the River Niger, as well as the most significant impact and preferred means of plastic pollution and regulation. The main findings indicate that disposal of plastics is the determinant source of plastics and micro plastics in the River Niger. The most significant impact of plastic pollution was identified as reduction in the accessibility of certain areas of the river. Behavioral instrument is indicated to be the most preferred means of plastic pollution control and regulation. Hence, there is an urgent need for improved awareness among local communities. This can be achieved through education programs, which will help to reduce the use of single-use plastics while also reducing littering in these areas. The paper also recommends that more research be conducted on how these pollutants affect human health and ecosystems.
