The industrial area chosen for sampling is Ungwan Romi, which hosts major bottling companies like Nigerian Bottling Company (NBC) Coca-Cola and Pepsi Company, located a short distance from each other. This area experiences significant traffic congestion due to the transportation of raw materials and finished products by trucks to and from these bottling plants. In contrast, Romi bus stop was selected as the residential area for sampling, characterized by settlements without any industrial activities occurring in the vicinity.
