The immediate past Deputy Vice-Chancellor (Management Services) of the University of Ilorin, Prof. Suleiman Folorunsho Ambali, has warned of rising threats from emerging chemical contaminants, urging urgent measures to protect human health and the environment.
Prof. Ambali delivered the warning during a plenary lecture on February 9, 2026, at the 3rd Biennial Conference of the Forum of Nigerian Toxicologists (FONTOX), held at the former Senate Chamber, Old Faculty of Arts, University of Ilorin.
A renowned environmental toxicologist, he highlighted the growing challenges posed by microplastics, per- and polyfluoroalkyl substances (PFAS), and antimicrobial resistance, describing these as complex chemical threats that extend beyond traditional toxicology.
“Today, we face not only single poisons at defined doses, but complex chemical cocktails at chronic low concentrations,” Prof. Ambali said, noting that the foundational toxicology principle that “the dose makes the poison” now requires re-examination.
He advocated a proactive approach, emphasizing the role of Green Toxicology, Artificial Intelligence, and community engagement in addressing these challenges effectively.
Prof. Ambali stressed that building toxicological capacity is essential for sustainable development, particularly in Africa, stating: “We must work together to protect human health and environmental integrity from chemical harm.”
He also called for stronger regulatory frameworks, improved research infrastructure, and greater investment in toxicological science to better monitor and manage chemical risks.
“We stand at the intersection of chemistry and biology, of environment and health, of science and policy,” he said, highlighting the urgent need for collective action.
The former Dean of the Faculty of Veterinary Medicine urged governments, industries, and civil society groups to act decisively to mitigate the health and environmental risks posed by emerging chemical contaminants.
Prof. Ambali’s lecture underscored the critical importance of coordinated research, policy, and public awareness in safeguarding human and environmental health in Nigeria and beyond.
