In Nigeria’s historic city of Zaria, a breakthrough in environmental science is taking shape. Fatihu Kabir Sadiq, a dedicated researcher from the Department of Soil Science at Ahmadu Bello University (ABU), is leading a crucial fight against persistent organic pollutants (POPs)—toxic chemicals that refuse to break down in the environment, threatening ecosystems and human health for decades.
Sadiq’s recent review, published in the respected journal Current Research in Biotechnology, sheds light on cutting-edge solutions to tackle these stubborn pollutants. His research highlights advanced remediation methods that go beyond traditional, often ineffective, cleanup efforts.
“Advanced oxidation processes (AOPs) and nanotechnology are at the forefront of this revolution,” Sadiq explained. “These methods not only degrade POPs more effectively but also do so in a more environmentally friendly manner.”
POPs, which originate from sources like pesticides, industrial waste, and chemical manufacturing, persist in soil and water long after their use has ceased. Their resilience has made remediation difficult, often requiring costly, chemical-heavy interventions that still leave harmful residues behind.
Innovative technologies like photocatalysis and AI-driven nanotechnology offer new hope for sustainable pollution control
Among the promising technologies spotlighted by Sadiq is photocatalysis, a green technology that uses natural sunlight to activate catalysts such as titanium dioxide (TiO₂), breaking harmful pollutants into harmless components. “Photocatalysis offers a green approach to remediation,” he said. “It leverages natural sunlight, making it a cost-effective and sustainable solution, especially for regions with abundant solar exposure like Nigeria.”
Sadiq’s review also delves into the growing role of nanotechnology in environmental cleanup. Nanomaterials possess high surface areas and reactive properties, allowing for more targeted and efficient breakdown of pollutants.

By integrating these techniques with artificial intelligence (AI), remediation strategies can be optimized in real-time, leading to more adaptive and effective interventions. “AI-driven process optimization can significantly enhance degradation efficiency,” Sadiq noted. “With AI, we can continuously monitor pollution levels and adjust treatment processes instantly.”
The potential benefits extend far beyond agriculture and public health. In Nigeria’s oil and gas sectors—where soil and groundwater contamination by POPs is a major concern—these technologies could help industries meet stringent environmental standards, reduce cleanup costs, and bolster their green credentials.
According to experts, embracing such technologies could position Nigeria as a leader in sustainable environmental practices in Africa, setting the standard for how developing nations tackle pollution challenges in the 21st century.
However, Sadiq warns that innovation alone is not enough. “We need interdisciplinary collaboration, strong policy support, and international partnerships to truly scale these technologies and make them accessible,” he emphasized. “The future of environmental health depends on how well we integrate science, technology, and governance.”
His call for a united approach echoes a growing consensus among global environmental scientists, as the world faces mounting climate and pollution crises. Sadiq’s work, though grounded in Nigeria, represents a beacon of hope for a cleaner, healthier planet.
As industries increasingly seek greener, more sustainable methods to operate, breakthroughs like Sadiq’s provide practical pathways toward achieving global environmental goals and safeguarding future generations.
