“…This leaching process can regulate the bio‐availability of certain metals in the soil and their absorption by plants based on intrinsic properties of each element. Furthermore, The different behavior of heavy metals in the terms of their uptake by plant, affected by alterations in soil chemical conditions, has been confirmed by Zhou et al (2023). As an overall result, AI proved to be a better option for ensuring the safety of the grains based on the amounts of more toxic elements of Cd and Pb and as well as the proximity of Cr contents found in both treatments.…”

This study examines the effects of three irrigation regimes with a combination of saline water and treated wastewater on the accumulation of heavy metals in barley grains. A field experiment was designed as a split‐split plot arrangement in a randomized complete block design, in which treatments were different irrigation regimes (50, 70 and 100% full irrigation) and irrigation water types (saline water (SW), treated wastewater (TW), mixed water resources (MWR) and alternative irrigation (AI)). After cultivation and harvesting of the barley crop, the grain yield, 1000‐grain weight and contents of heavy metals in the grains were measured. The grain yield was enhanced by TW alone, MWR and AI to 12.8, 5 and 9.5% under 70%‐deficit irrigation, and 58.3, 21.7 and 8.7% under full irrigation, respectively. Based on the guidelines for safe limits of heavy metals in edible plants and livestock feed, the barley grains were safe for livestock and toxic for humans. The trend of heavy metal contents in the grains was Fe>Zn>Pb>Cu≥Cr>Cd. Irrigation with saline water compared to treated wastewater increased Fe, Cu, Zn, Pb, Cd and Cr contents in the grains to 11.75, 10.97, 5.22, 19.15, 3.45 and 9.21%, respectively. The amounts of toxic elements of Cd and Pb were maximized by using MWR, while the Cr content in the grain was maximized by using AI. There were no significant difference in the metal uptake by the grains among all irrigation regimes in any irrigation water resource. However, compared to the other irrigation regimes, the full irrigation resulted in lower Zn, Cu and Cd contents, while the 50%‐deficit irrigation led to lower Pb and Cr contents in the grains. Therefore, irrigation with TW is recommended based on the grain yield, while AI is suggested due to lower Cu, Pb and Cd contents in the grain, and MWR is recommended due to lower Cr content. Furthermore, full and 50%‐deficit irrigation regimes are recommended to respectively maximize grain yield and minimize the toxic metal contents in the grain.

Heavy metal contamination often occurs when there is an abnormal discharge of metal in the environment. This is caused mainly by human activities such as agriculture, mining and industrialization. When this heavy metal gets into the environment, it adversely affects plants, humans and aquatic biodiversity. Conventional treatment methods have been applied extensively, hence these methods are inefficient and expensive to carry out. This study was conducted to assess whether castor plants could be able to absorb heavy metal actively from the soil. Metal ions determined are lead and copper at different concentrations of 1.5, 2 and 2.5 g/dm3. The soil located at Gombe State University Botanical Garden was used for the cultivation of the plant. Acid digestion and Atomic Absorption Spectroscopy were used for metal determination. The results of the study showed that Copper and Lead were absorbed the highest in the leaves than in stem and root by the absorption efficiency of 100, 91 and 87% respectively. The plant leaves and roots accumulate high Lead content of 2.661, 2.43, in the root, 1.26, 1.52, and 0.031, 0.3 in the stem for both lead and copper respectively. Results of translocation factor revealed the highest absorption of metal from Root to stem of 1.83, 1.98, and the least was 0.36, 0.34, for copper and lead respectively.
