Recently, concerns have been raised regarding environmental contamination by heavy metals, which pose significant risks to agriculture and human health. Industrial and domestic waste discharge into the environment contributes to the accumulation of toxic metals such as cadmium (Cd) and zinc (Zn) in soil and water. These metals, when absorbed by plants, lead to physiological, morphological, and biochemical disruptions, including chlorosis, necrosis, and reduced crop yield. Furthermore, excessive metal concentrations generate reactive oxygen species (ROS), which interfere with cellular functions, including DNA and protein integrity. In Nigeria, heavy metal pollution in soil is escalating due to erratic rainfall patterns and the increasing use of wastewater for irrigation, particularly in semi-arid regions. Understanding the bioaccumulation and health risks associated with these contaminants is crucial for ensuring food safety and sustainable agricultural practices.
