Background and aim: Lead (Pb) toxicity poses environmental challenges, disrupting plant growth and micronutrient dynamics. This study investigated the impact of Pb toxicity on iron (Fe) and zinc (Zn) accumulation in four evergreen species: Dodonaea viscosa, Myrtus communis, Platycladus orientalis, and Ficus benjamina. Method: A pot experiment was conducted in Erbil, Iraq, using sandy clay loam soil treated with Pb at 0, 100, 200, and 300 mg/kg. Plants were grown for six months in a factorial randomized design (two factors: species and Pb doses) with three replications. Fe and Zn levels in roots, shoots, and soil were analyzed using a Genius XRF device. Data were analyzed with SPSS version 28, employing descriptive statistics, two-way ANOVA, Pearson’s correlation, and multiple regression (P < 0.05). Results: Significant differences in Fe and Zn accumulation were observed among species and Pb treatments. Dodonaea viscosa showed the highest root Fe accumulation, while Ficus benjamina exhibited elevated Zn levels. Soil metal levels remained stable but varied by species. Two-way ANOVA confirmed significant effects of Pb concentration and species on metal accumulation. Pb had a moderate negative effect on soil Zn levels. Conclusions: Dodonaea viscosa shows promise for phytoremediation. Further research should explore long-term and molecular mechanisms for managing Pb-contaminated soils.
