Assessing the Impact of Heavy Metal Contamination on Okra: A Study of Zinc and Cadmium Bioaccumulation
Abstract: 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 …
