Research

Dr. Jegede's research focuses on understanding the ecological impacts of environmental pollutants through the study of soil-based invertebrates. Our work encompasses pesticides (neonicotinoids, rodenticides), heavy metals, per- and polyfluoroalkyl substances (PFAS), microplastics, and other emerging contaminants. We employ soil bioindicators to assess ecosystem health and develop risk assessment frameworks for environmental protection.

Pesticide Toxicity in Soil Ecosystems

Investigating the effects of pesticides, including neonicotinoids and rodenticides, on soil invertebrates such as Collembola and earthworms. Our research evaluates survival, reproduction, and behavioral responses to understand ecological risks.

Heavy Metal Contamination and Soil Health

Assessing the impact of heavy metals (e.g., nickel, cadmium) on soil bioindicators. Studies examine how soil properties and aging time influence metal bioavailability and toxicity to soil organisms.

PFAS Contamination in Agricultural Soils

Exploring the presence and effects of per- and polyfluoroalkyl substances (PFAS) in agricultural environments. Research focuses on understanding how these persistent pollutants affect soil invertebrate communities and ecosystem functions.

Microplastic Pollution and Soil Invertebrates

Examining the ecological impacts of microplastic contamination on soil-dwelling organisms. This research aims to understand how microplastics affect soil structure, invertebrate behavior, and ecosystem health.
