Evaluation of Pb, Cu, Zn, Cd, Ni and Fe levels in Rosmarinus officinalis labaiatae (Rosemary) medicinal plant and soils in selected zones in Jordan

Abstract

The concentration of heavy metals including Pb, Cu, Zn, Cd, Ni and Fe in different parts of Rosmarinus officinalis medicinal plant grown in Jordan were evaluated. Medicinal plant samples and soil samples were collected from three different zones in Jordan (Irbid, Al-Mafraq and Ma'an). Samples were analyzed by atomic absorption spectrometry (AAS) after chemical treatments using acid digestion procedures. Heavy metal levels in washed and unwashed in each part of R. officinalis were analyzed and compared statistically. Results show that concentrations of investigated heavy metals were varied from plant part to another part of R. officinalis. For example, Pb, Zn, Cu and Cd in most parts of R. officinalis in the three zones were concentrated in the following order: flowers, leaves, stems, whereas Pb, Ni and Fe were concentrated in order as follows: leaves, flowers and stems. Heavy metal concentrations in soil samples was evaluated and correlated with their levels in R. officinalis. Two standard reference materials of plant (SRM 1790a; spinach leaves and CRM 281; rye grass) and one standard reference materials of soil (GBW 07406) were examined to validate the method used. Results show that high recoveries were obtained.

Assessment of Heavy Metals in Different Parts of Ruta chalepensis L. Rutaceae Medicinal Plant and Soil Samples Collected from Three Selected Zones in Jordan

“…It is known that herbal and medicinal plant have been used for treatment of diseases, especially in the developing countries (Chan, 2003El-Rjoob et al, 2008).…”

Trace elements in aerial parts and rhizosphere of Thymus pannonicus All.

“…Growing on a soil rich in potentially toxic heavy elements can lead to accumulation of higher amounts of these elements in plant tissues. Bearing in mind that plants are an essential part of regular diet, questions of their safety for human health have frequently arisen [2,3]. On the other hand, holding a focus on two environmental compartments (both soil and plant tissues), a close insight on the elemental composition could be reached, which can prove itself significant in highlighting its influence on biosynthetic pathways and production of secondary metabolites, e.g.…”

Zinc Sulphate and Nano-Zinc Oxide Effects on Some Physiological Parameters of Rosmarinus officinalis

“…Four nut fruit with brown color, firm, round and its egg is small inside the fruit. All leaves, blossoms and scented members are aromatic [17]. Rosemary is native to the Mediterranean region well-calcareous areas that tolerate arid and semi-arid hot weather [17].…”

“…All leaves, blossoms and scented members are aromatic [17]. Rosemary is native to the Mediterranean region well-calcareous areas that tolerate arid and semi-arid hot weather [17]. Rosemary components are very important in various industries, due to its numerous properties, including convenient and good odor which is emitted as a sedative, food preservative, preservatives, colors and flavors of food and very potent antioxidant that has high consumption [18].…”
