Abstract

This study assesses the ecological situation near fuel filling stations in Thi-Qar Governorate by analyzing the alteration of heavy metals in soil and vegetation. The objective is to evaluate the environmental status of the area, considering heavy metal accumulation as an indicator of soil pollution and the impact of plants on fuel pollutants. Research methods include the measurement of heavy metals using an atomic absorption device and calculation of total soil and plant pollution factors. Results indicate high concentrations of lead (Pb) in soil samples from stations 1 and 2, with significant differences observed (p < 0.05). However, concentrations of other heavy metals (Cu, Zn, Cd) remained within permissible limits. The study highlights the role of soil and root systems in heavy metal accumulation and the potential impact on the food chain due to combined air and soil pollution near fuel filling stations.
