Title: BINARY AND TERNARY METALS ADSORPTION FROM GREYWATER USING SPENT GREEN TEA AS A NOVEL ADSORBENT Authors: Gameli, R. B.H.; Alhassan, E. H.; Duwiejuah, A. B.; Abarike, E. D.; Bawa, A. Abstract: Adsorption is one of the most easy-to-operate, less costly, efficient and, most importantly, environmentally friendly methods of removing toxic metals from aqueous environments. We used spent Impra Green Tea Ginseng Flavoured to recover mercury (Hg2+), lead (Pb2+) and cadmium (Cd2+) in binary and ternary systems from greywater. We undertook this study in binary and ternary systems at adsorbent dosages with a corresponding 100 mL varied initial metal concentrations of the greywater. The adsorption efficiency at varied concentrations and dosages in the binary systems by the spent tea waste ranged from 38.5% to 100% for lead, 11.50% to 100% for cadmium and was 100% for mercury. In the ternary system, the adsorption efficiency of toxic metals ranged from 28.91% to 72.85% for cadmium and was 100% for mercury and lead. The maximum adsorption capacity (Qe ) for toxic metals in the binary system ranged from 38.46 to 81.97 mg/g for Pb2+ and 12.64 to 56.82 mg/g for Cd2+. The Langmuir adsorption isotherm model was the best fit for the adsorption of toxic metals by Impra Green Tea Ginseng Flavoured. The pH under which the experiments were conducted showed very high removal efficiency for lead and mercury but lower removal efficiencies for cadmium. Spent Impra Green Tea Ginseng Flavoured can be used as an effective and low-cost adsorbent of toxic metals from greywater or wastewater. Based on our findings, further studies should be conducted to determine the effects of varying the contact time, temperature and elevated metal concentrations in the greywater or other wastewater

Title: DISINFECTANT IMPACTS ON WATER QUALITY AND FISHES DURING THE FIGHT AGAINST COVID-19 SPREAD Authors: Iyiola, A. O.; Kolawole, A. S.; Asiedu, B.; Abobi, S. M. Abstract: The World Health Organization recommended disinfectant use as a way of tackling the global spread of corona virus pandemic (COVID-19). A total of 246,245,186 infection cases, 246,134,984 recoveries and 4,995,890 deaths have been reported across the world with 3,767,744 confirmed cases in over 160 countries. The spread of the virus was addressed by restricting human and vehicular movements, compelled use of sanitizers, social distancing, and wearing of masks. Chlorine, alcohol and bleach disinfectants, which contain different active compounds, were also used to combat the spread of the virus by applying them on surfaces. The indiscriminate use of disinfectants was reported to have disastrous effects on water quality, and on skin and organs of fish in the long run. The virus affected generally almost all spheres of life. To this end, disinfectants must be used at recommended rate of application, and the proper disposal of wastewater is also important, so as to limit transmission of diseases. Strict adherence to human activities based on the approved guidelines by the government and stakeholders in the health sector is essential for a healthy life. This paper therefore reviews the types of disinfectants, and their effects on water quality, fish species and sustainability of the environment.

Title: EFFECT OF SAND MINING ON RIPARIAN LANDCOVER TRANSFORMATION IN DALLUNG-KUKOU CATCHMENT OF THE WHITE VOLTA BASIN, GHANA Authors: Nasare, L. I.; Opoku, S. A.; Amponsah, A.; Tom-Dery, D.; Asante, W. J.; Baatuuwie, B. N. Abstract: Rapid urbanization has increased demand for sand in the construction industry to meet housing and infrastructure needs of urban population. The Dallung-Kukuo catchment of the White Volta River Basin is a major sand mining site for the construction industry in Tamale and other peri- urban communities. On the contrary, the river serves as a major source of water supply to the population. Riparian vegetation is essential to water protection, but research has focused extensively on the impact of sand mining on water quality in the river basin. The present study employed GIS and remote sensing techniques coupled with in-situ vegetation sampling to assess riparian land cover changes from 1990 to 2021. Land cover images of the catchment revealed a 14.9% increase in sand mining area, while river bed area and woodland cover decreased by 0.7% and 20%, respectively, from 1990 to 2021. A comparison of woody plant diversity also showed a higher Shannon diversity index in the unmined area of the riparian zone (3.0) compared to the sand mining area (2.0). Environmental Protection Agency and traditional authorities should intensify monitoring to protect the White Volta basin from unsustainable exploitation.

Title: ASSESSMENT OF ANTHROPOGENIC ACTIVITIES, ENVIRONMENTAL LITERACY AND MANAGEMENT PRACTICES IMPACTING LAKE BOSOMTWE Authors: OWUSU-BOATENG, G.; AGYEMANG, T. K.; AMPOFO-YEBOAH, A.; SARPONG, K. Abstract: The communities in the Bosomtwe basin depend on Lake Bosomtwe for their livelihoods. However, the lake has continued to experience human-driven degradation in recent times. We conducted a survey of the main anthropogenic perturbations of the lake, the level of awareness of the communities of anthropogenic interventions and their effects on lake health, and the effectiveness of its management practices using a structured questionnaire administered to 350 respondents. Data were analyzed using non-parametric Kruskal Wallis and Mann Whitney U-tests. Crop farming, fishing, fish mongering, animal rearing, timber harvesting, hospitality operations, washing, other trades, and illegal mining were the anthropogenic interventions of the most devastating consequence, promoted by a low level of education and environmental awareness. Although the regard for directives of the traditional authority to govern the lake declined subtly, the situation is worsening due to inadequate resources for the Bosomtwe District Assembly, the government agency responsible for coordinating the stakeholders of the lake and providing an adequate decision-making basis for its conservation. The results, which have direct practical implications for water management, suggest the need for well coordinated policies and strategies for law enforcement and education of basin communities on the causes and effects of lake degradation.
