Abstract

Heavy metal pollution poses a significant health risk in developing countries, particularly in relation to drinking water, household water, and food crops. The accumulation of heavy metal(loid)s (HM) in plants can disrupt the food chain, including medicinal and aromatic plants (MAPs) that are utilized for human ailment treatments. Interestingly, MAPs also possess the potential for soil restoration in areas contaminated with HM. This research examines the concentration of HMs in three commonly used remedies, sage, oregano, and lavender within the Zonguldak province of Turkiye. This region characterized by high densities of coal enterprises and thermal power plants. The study employed inductively coupled plasma mass spectrometry (ICP-MS) to analyze 19 elements in both soil and plant samples collected from the Gokcebey region. Metal contamination levels in soil were assessed using the contamination factor (CF) parameter while the bioaccumulation factor (BAF) was utilized to evaluate the extent of each element penetration within plant systems. The result indicated that oregano exhibited higher accumulation of nickel (Ni), chromium (Cr), and silicon (Si), sage accumulated greater amounts of strontium (Sr), zinc (Zn), and manganese (Mn), and lavender demonstrated elevated accumulation of nickel (Ni), copper (Cu), mercury (Hg), and selenium (Se). These plant species exhibit potential for phytoremediation purposes due to their selective accumulation of certain heavy metals, such as Ni, Sr, and Hg. This study emphasizes the importance of identifying MAPs with high bioaccumulation potential for phytoremediation and suggests that these plants could be employed to restore soil in heavy metal-contaminated areas.
