Word: Heavy Metal Concentration, Environment, AAS, Vegetables and Bioaccumulation

Small amounts of heavy metals are commonly found in our environment and diet, and they are actually necessary for good health. However, large amounts of heavy metals can cause acute or chronic toxicity. This is a concern because heavy metals can be harmful to humans and animals, and they have the potential to bioaccumulate in the food chain. In a study conducted in the Jigawa North West Senatorial Zone, the levels of selected potentially toxic metals (Pb, Mn, Ni, Zn, Cd, and Cu) were assessed in selected vegetables (cabbage and lettuce), water, and soil from farms along some irrigation areas. The samples were analyzed using an Agilent Technologies 200 series Atomic Absorption Spectrometer 240FS after being digested with a freshly prepared aqua regia. The results showed that the concentrations of zinc in both water, soil, and vegetables were below the allowable levels recommended by the World Health Organization (WHO), the United States Environmental Protection Agency (EPA), and the United States Food and Drug Administration (FDA). On the other hand, manganese concentrations in water, soil, and vegetables were also below the allowable levels recommended by the WHO. However, lead concentrations in water exceeded the allowable level set by the WHO, while the concentrations in soil and vegetables were within the recommended limits. For cadmium, the concentrations in both water and vegetables were below the allowable levels set by the WHO, while the concentration in soil was within the recommended limit. The values of copper in both soil and vegetables exceeded the allowable level set by the WHO. Finally, nickel concentrations in water were above the allowable level set by the WHO, while the concentrations in soil and vegetables were within the recommended limits. It is important to note that high concentrations of copper can be toxic to organisms and can negatively impact aquatic ecosystems. Additionally, nickel in soil can adversely affect plant growth and soil microbial diversity. The transfer factor of manganese and zinc in both lettuce and cabbage was categorized as low, indicating that the transfer of these metals from soil to plants is limited. On the other hand, the transfer factor of cadmium in lettuce and cabbage varied across different months, with some categorized as moderate.
