The levels of heavy metals are very important in pistachio nuts, because the edible nuts have an important and increasing role in human nutrition. Pistachio is one of the native nuts of Iran which contains high genetic resources, but there is insufficient information regarding nutritional properties and other elements like heavy metals. The objective of the present study was to investigate and compare heavy metals contents in the kernels of various pistachio samples including: 'Daneshmandi' , 'Sephid' , 'Garmeh' , 'Momtaz' , ' Ahmad Aghaei' , 'Badami Zarand' , Pistacia atlantica Desf. ('Baneh'), Pistacia vera 'Sarakhs' and chance seedling as 'Non-grafted 1' , 'Non-grafted 2' and 'Non-grafted 3' . Inductively coupled plasma emission spectrophotometer (ICP) was used for the determination of aluminium, chromium, nickel, copper, strontium, arsenic, cadmium and cobalt concentrations in pistachio kernels. This study showed that there were significant differences among the samples in all measured heavy metals except the arsenic, cadmium and cobalt. The content of aluminium varied from 3.22 to 9.59 (mg kg -1 of dry matter) and chromium concentration from 0.60 to 1.86 (mg kg -1 of dry matter). The nickel content of examined pistachio samples was found between 0.43 and 3.63 (mg kg -1 of dry matter) and copper ranged from 3.20 to 12.33 (mg kg -1 of dry matter). The strontium content was observed between 4.96 and 24.93 (mg kg -1 of dry matter). The contents of arsenic, cadmium and cobalt not reported, because their amounts were lower than the detection limit of the applied measuring method (ICP). These data demonstrated that the concentrations of heavy metals in pistachios varied by cultivar.

The potentiometric characteristics of a new Cu2+‐selective electrode based on 2‐(benzyliminomethyl)‐6‐methoxy‐4‐(4‐methoxyphenyl‐azo) phenol as an efficient ionophore has been evaluated. The effects of influential parameters on the potentiometric responses such as the amount of plasticizer, the amount of ionophore, pH of the sample solution, and the effect of coexisting ions on the electrode signal were subsequently investigated. The selectivity of the electrode was assessed by calculating the selectivity coefficients using the matched potential method. The optimum ratio of the amount of materials required for the preparation of the electrode was found to be 1.7: 32.1: 64.2: 2.0 corresponding to carboxylated PVC, dimethyl sebacate as solvent mediators, potassium tetrakis (p‐chlorophenyl) borate as the anion localizing agent, and ionophore, respectively. The electrode had a fast response (7s) as well as a satisfactory Nernstian slope (29.26±0.91 mV/decade) to Cu2+ over a wide concentration range of 2.0×10−6‐ 5.0×10−2 M with a low detection limit of 5.9×10−7 M. The developed sensor was successfully used for the potentiometric titration of Cu2+ ion with EDTA and subsequently, efficient determination of this metal ion in a mineral water sample was performed.

This work aimed to combine solid phase extraction (SPE) with inductively coupled plasma mass spectrometry for the determination of multi-elements (Pb, Cd, and Zn) simultaneously. This combination allows the purification of the solution by minimizing matrix effects, the separation of the analytes and a fast determination of multiple elements (Pb, Cd, and Zn) in seconds. A syringe-solid phase extraction (SYRINGE-SPE) method was developed based on adsorption/desorption of metals onto amino-functionalized hollow core mesoporous shell silica spheres (NH 2 -HCMSSs). The separation of NH 2 -HCMSSs from aqueous phase was assessed by capping the syringe with 0.2-mm filter. The results showed that the quantitative recovery of analytes was obtained at pH 6 by elution with 3 M HNO 3 . The developed method is applicable in the presence of different coexisting ions. The limit of detection was 0.021, 0.004, and 0.007 mg L À1 for Pb(II), Cd(II), and Zn(II) ions, respectively, whereas the limit of detection of the instrument without combination with the SYRINGE-SPE was 0.699, 0.123, and 0.24 mg L À1 for Pb(II), Cd(II), and Zn(II) ions, respectively. The relative standard deviations were 7.4, 6.2, and 5.4% for Pb(II), Cd(II), and Zn(II), respectively. The method was validated using corn bran (8433) certified reference material. The method was successfully applied for the determination of Pb(II), Cd(II), and Zn(II) in bottled water, tap water, beet, radish, carrot, potato, sweet potato, and turnip samples.Abbreviations: AAS, atomic absorption spectrometry; EDS, energydispersive X-ray spectroscopy; FTIR, Fourier transform infrared; ICP-MS, inductively coupled plasma mass spectrometry; LOD, limit of detection; LOQ, limit of quantification; NH 2 -HCMSS, amino-functionalized hollow core mesoporous shell silica sphere; SEM, scanning electron microscopy; SPE, solid-phase extraction; SYRINGE-SPE, syringe-solid phase extraction; TGA, thermal gravimetric analysis 720
