Environmental Research

The Environmental Toxins and Kidney Health Research Group focuses on investigating the environmental determinants of Chronic Kidney Disease (CKD) in Gashua and surrounding communities in Yobe State, Nigeria. In recent years, there has been growing concern about the increasing burden of CKD in this region, particularly cases that are not clearly linked to traditional risk factors such as hypertension or diabetes. This raises critical questions about the role of environmental exposures in disease development.

Our research specifically examines the relationship between environmental toxins especially nephrotoxic heavy metals such as lead (Pb), cadmium (Cd), arsenic (As), chromium (Cr), and mercury (Hg) and kidney health outcomes. These contaminants may enter the human body through multiple pathways including drinking water, consumption of contaminated food crops and fish, and exposure to polluted soils.

Gashua, being a riverine and agricultural community, presents a unique environmental context where irrigation practices, sediment deposition, and agrochemical use may contribute to the accumulation of toxic substances in the ecosystem. Over time, these substances may bioaccumulate in human tissues, particularly in the kidneys.

Our research integrates environmental sampling, spatial analysis, and toxicological assessment to identify contamination hotspots and evaluate their potential health implications. By linking environmental exposure data with human health outcomes, this research aims to provide evidence based insights into the underlying causes of CKD in the region and contribute to preventive strategies.
