AAUA DON OLOLADE WARNS AGAINST GROWING ENVIRONMENTAL POLLUTION
…Varsity Holds 55th Inaugural Lecture
The rivers that many Nigerians depend on for drinking, cooking, and bathing are being systematically poisoned by industrial and urban waste, a university don has warned, declaring that “our existence is being threatened” by continuous exposure to avoidable pollution.
Professor Isaac Ayodele Ololade of Adekunle Ajasin University, Akungba Akoko, issued the stark warning on Tuesday while delivering the institution’s 55th Inaugural Lecture, titled “Environmental Chemistry: The Science Behind a Healthier Planet.”
Drawing on years of research into important rivers across southwestern Nigeria, the professor revealed that both direct contact with and consumption of water from these polluted sources pose significant cancer risks. “Both dermal and ingestion routes are practically significant in the carcinogenic risk assessment to human health in all the rivers investigated in our studies,” he explained. “Hence, attention should be paid to the domestic use of these rivers for cooking and recreational activities, including swimming, to limit exposure to the pollutants.”
He added: “Based on the results of our several studies on important rivers within southwestern Nigeria and the dependence of many on river resources, either directly or indirectly, I can say authoritatively that our existence is being threatened because of continuous exposure to avoidable risks.”
Prof. Ololade called for urgent implementation of a zero-discharge policy, saying, “The current data suggest that it is high time to take appropriate steps toward the protection of our water resources. Moreover, the zero-discharge policy has to be implemented to reduce contamination of our river bodies. The current unfriendly attitude towards the safe and productive use of our water resources, including unlimited and unregulated direct point sources of pollution, may not provide the appropriate conditions that can protect and support marine protection that encourages recreation, tourism, and sustainable development.”
To underscore the human toll of environmental neglect, the professor presented shocking evidence from auto mechanics in Ondo State. Blood and urine tests conducted on the workers showed “unacceptably high levels of carcinogenic matter” and the presence of toxic metals, which he attributed to the improper disposal of workshop waste.
He advised that every auto mechanic workshop should be strictly monitored and recommended urgent measures, including the segregation of wastes using designated containers, the development of spill response plans, the training of mechanics and apprentices on spill procedures, and the regular monitoring of workshop environments for air quality.
To tackle the devastating health and environmental hazards posed by unchecked waste disposal, the professor called for a multi-pronged approach from governments at all levels. He listed several key measures, including the enactment and strict enforcement of regulations, heavy fines and penalties for offenders, and an aggressive public awareness campaign to encourage responsible habits.
He also advocated for a total ban on single-use plastics, the provision of adequate waste bins, and the creation of robust recycling programmes for paper and plastics. Investment in modern landfills with proper containment systems was also crucial, he said, warning against open landfills that “slowly poison soil and water.”
Prof. Ololade further recommended the use of waste-to-wealth initiatives, such as incineration, to reduce waste volume and generate power, as well as the deployment of digital platforms to optimise waste collection routes and track waste more efficiently.
The inaugural lecturer, however, acknowledged that developing countries like Nigeria face significant hurdles in ensuring a waste-free environment. He identified inadequate funding, a lack of infrastructure, and a shortage of trained staff to manage complex waste systems as major obstacles, noting also that no single solution works effectively, requiring a combination of strategies, and that securing funding for advanced technologies and ongoing maintenance remains a persistent challenge.
Despite these difficulties, Prof. Ololade ended his lecture on a note of cautious optimism, urging collective action from citizens, communities, and governments. “As we confront the pressing challenges of environmental degradation, the vision of a pollution-free world feels increasingly distant,” he said. “However, through collective efforts and innovative solutions, this ideal can shift from being a mere fantasy to a tangible goal. By prioritising sustainable practices, embracing renewable energy, and fostering a culture of environmental stewardship, we have the power to transform our reality.”
He concluded: “It’s time to ask ourselves: can we make a pollution-free environment a reality? The answer lies in our hands. Let’s commit to making it happen.”
Speaking while introducing the inaugural lecturer, the Vice Chancellor of AAUA, Prof. Olugbenga Ige, described Prof. Ololade as a consummate academic and researcher who is well-regarded both nationally and internationally, and whose work has brought positive global attention to the institution.
The Vice Chancellor added that the university’s inaugural lecture series aims to give professors the platform to showcase their research to society, with a view to bringing improvement and development to the wider community through novel ideas.
