“…Sr is an element that can be found in substantial concentrations in nature, as a result of natural mineral degradation or consecutively on polluting anthropic activities [33]. The transfer of such a contaminant from the environment to plants is an important first step in the contamination of the food pathway.…”

ABSTRACT. We have determined the amount of some heavy metals (Al, Ba, Cr, Cu, Fe, Mn, Ni, Sr and Zn) contained in 18 herbal tea samples that had been bought from local markets where different parts of plants (leaves or flowers) are consumed especially for medical purposes in Turkey by ICP-OES. The validity of the analytical procedure was checked by analyzing INCT-TL-1 CRM certified reference material. The results from the analysis of CRM were all within the 95% reliability limit. The experiment results comply with the values reported in the literature. The wet decomposition method was used to solubilize the metals. The amount of the heavy metal that had passed to the tea via infusion has also been determined. The lowest and highest amounts of the metals found are: Al 268

“…For instance, strontium has a variety of commercial and research use like: in the manufacture of X-ray absorbing glass for cathode ray tubes, in the electrolytic zinc process, electroceramics and oxide superconductors. From all these industry results wastes and secondary products which will severely pollute the environment if the wastes are not treated well [1], [2]. The ingestion of Sr 2+ can lead to the replace of the Ca 2+ from the human body due to the chemical similarity of these two ions, and this fact can cause different illnesses.…”

Novel composite magnetic nanoparticles (CuFe 2 O 4 ) were synthesized from industrial sludge by acid leaching, chemical exchange, and ferrite processes in the laboratory. For the first time, these products were applied to investigate the Sr adsorption kinetics and the related thermodynamics in seawater. Rapidly enhanced Sr adsorption was observed when the solution pH changed from 2.61 to 10.25. The maximum adsorption capacity was 23.04 mg·g −1 at 318 K (pH 10.25). Sr adsorption decreased with the increase of the ionic strength from 0.01 to 0.5 mol·L −1 at pH 2.61-pH 10.25, indicating that the outer-sphere mechanism was involved in the Sr adsorption at the pH interval. This reaction is spontaneous and endothermic, as indicated by the negative change in the standard free energy (∆G • = −5.68, −6.45, and −7.23 kJ·mol −1 at 298, 308, and 318 K, respectively) and positive ∆H • value (2.11 kJ·mol −1 ). The positive ∆S • (9.38 mol −1 ·K −1 ) further confirms that the randomness increased at the solid-solution interface during adsorption. These new results indicate that the composite magnetic nanoparticles can be used for the removal of radiogenic 90 Sr nuclide in seawater that was released after the 3/11 earthquake offshore of Japan.
