A Nigerian environmental chemist, Olamide Ogundele, is gaining international recognition for her pioneering research into the long-term effects of perfluorooctanesulfonic acid (PFOS) contamination in food crops—a major emerging threat to global agriculture and public health.

Ogundele’s latest study, titled “Physiological and Metabolic Responses of Wheat (Triticum aestivum L.) after One Generation Exposure to Perfluorooctanesulfonic Acid (PFOS),” presents compelling evidence that PFOS contamination in soil not only affects the exposed generation of crops but also persists in future generations. The research was conducted in the United States and focuses on wheat, a staple crop in many parts of the world.

Her findings reveal that even a single generation of exposure to PFOS—classified as a toxic, long-lasting chemical—can result in its residual presence being detected in the third generation of plants. More significantly, she discovered changes in key metabolic compounds within the seeds, including sugars, amino acids, and lipids, indicating that PFOS contamination disrupts the plant’s internal biochemistry and potentially reduces both its health and nutritional value.

“This isn’t just about contamination now,” Ogundele said. “This is about long-term damage to our food systems and ecosystems, with potential consequences that may take years to fully understand.”

PFOS is part of a broader class of chemicals known as per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals” due to their resistance to degradation in the environment. These substances are commonly used in industrial processes and consumer products, including non-stick cookware, firefighting foams, and stain-resistant fabrics.

Ogundele’s research raises critical concerns about the widespread and often unnoticed spread of PFOS in the environment, especially in agricultural soils. Her work poses urgent questions: What are the sources of PFOS contamination in farmlands? How much has already infiltrated the food chain? And what are the broader ecological consequences?

Experts in environmental science have described the study as a major advancement in understanding the hidden risks posed by PFAS to global food security. By focusing on intergenerational effects, the research highlights the invisible legacy that toxic pollutants may leave on food crops, soil health, and ecosystem stability.

Her work underscores the need for intensified surveillance of PFAS contamination in agricultural areas, particularly in developing countries with rapidly expanding food production sectors. She also calls for closer collaboration between scientists, regulators, and agricultural stakeholders to address the challenges of chemical pollution and to develop effective remediation strategies.

A passionate advocate for sustainable science, Ogundele is proud to represent Nigeria in the international scientific community. Her research, while grounded in rigorous analytical chemistry, is driven by a broader mission: to protect food systems, preserve environmental health, and ensure a safer future for generations to come.
