ABSTRACT
Brewery effluent is one of the most occurring sources of pollution in water environment. Due to the increase in industrialization and urbanization the amount of industrial wastewater being discharged into rivers have increased significantly, thereby causing threats to aquatic lifeforms and other usage of water. The present study was conducted to assess the effects of brewery effluent on the chlorophyll content and stem girth of Sacciolepis africana and Ipomoea aquatica in Ikpoba River, Benin City, Edo State. In situ assessment was carried out from October, 2023 to January, 2024. Three sampling sites were designated and assessed fortnightly between the periods of 9:00 AM to 12:30 PM. The chlorophyll content and stem girth of study plants with physico-chemical parameters of the river were measured using handheld digital chlorophyll content meter, Vernier calliper and 7-in-1 water quality meter respectively. The pH of the River varied from 5.2 ± 0.2 downstream in January, 2024 to 6.8 ± 0.5 downstream in October, 2023 and at the point of discharge in November, 2023. The highest stem girth was recorded at point of discharge and it ranged from 10.77 ± 1.77 mm in October to 12.65 ± 1.68 mm in January, 2024. Similarly, there was an increase in stem girth of S. africana at point of discharge and downstream. But there was no significant differences (P > 0.05) in stem girth in both plants. Ipomoea aquatica exhibit higher sensitivity to brewery effluent pollution than S. africana, thus it is recomended for biomonitoring of aquatic environment.
