Abstract. Heavy metals pollution has become a worldwide problem, and its toxicity affects crop yield, environment, human and animal health, as well as, soil fertility. In this study, the quantities of different heavy metals including Pb, Cd, Cr and Co have been assessed in Basra governorate. Soil and date palm Phoenix dactylifera L. leaves have been collected from different sites (Zubair highway, Najibya electric power station, Faw, Qurna, Shat Al-Arab and Abo Al-Kaseeb districts) during the rainy and dry seasons. The analysis of heavy metals revealed that the total, available and leaf content of Pb was found to be high at all investigated sites during both season, followed by Cr, while the lowest averages of heavy metals were reported with Cd. Results indicate that the total level of heavy metals pollution during the dry season was higher than what was observed during rainy season in all analysed heavy metals. It is noteworthy, that the levels of Pb and Cd in Basra's soils have exceeded the permissible limits according to European standards, thus, an urgent interaction is required to decrease these levels by introducing a suitable remediation procedure.
