Essential elements (K, Ca, P, S, Cl, Mn, Fe, Cu, Zn, Ni, Br, and I) nonessential or toxic (Al, Ti, Si, Rb, Sr, As, Cd, Sn, Pb) were determined by energy-dispersive polarized x-ray fluorescence spectrometry in 14 seaweeds purchased local specialty stores Italy consumed humans. The differences between the algae species reached up to 2–4 orders of magnitude. Lithothamnium calcareum showed highest levels Al, Ti. Palmaria palmata concentrations K, Cl. content S was Chondrus crispus. Laminaria...
The determination of environmental contamination with natural and artificial actinide isotopes evaluation their source requires precise isotopic actinides, above all uranium plutonium. This can be achieved by alpha spectrometry or inductively coupled plasma mass (ICP-MS) after chemical separation actinides. performance a sector-field ICP-MS (ICP-SFMS) to low-flow micronebulizer membrane desolvation unit, "Aridus", was studied respect measurements plutonium at the ultratrace level. UH+/U+...
Levels of iron (Fe), manganese (Mn), chromium (Cr), copper (Cu), zinc (Zn), mercury (Hg), cadmium (Cd), and lead (Pb) in several types honey produced a region Central Italy were determined by atomic absorption spectroscopy (AAS). The degree humidity, sugar content, pH, free acidity, combined acidity (lactones), total also measured. These elements found to be present various proportions depending upon (1) the area foraged bees, (2) flower type visited for collection nectar, (3) quality water...
Ceterach officinarum Willd is a plant widespread throughout Europe and used in southern Italy as diuretic. Beliefs the benefits of C. aqueous extract treatment calcium oxalate kidney stones are widely held. Little known, however, about actual mechanism its antilithiatic action. Our results this vitro study corroborate good source antioxidants with high antioxidant effects. also demonstrate major impact on induced crystallization kinetics crystal morphology, showing critical role stone...
210Po and its precursor 210Pb in cigarette smoke contribute a significant radiation dose to the lungs of smokers. In this work, concentration was determined 17 most frequently smoked brands Italy. Samples tobacco, fresh filters, ash, post-smoking filters were analyzed; by alpha spectrometry after spontaneous deposition on silver disk. To verify radioactive equilibrium between 210Pb, lead one tobacco sample counting beta activity decay product 210Bi with gas flow proportional detector...
Soil concentrations of 239+240Pu, 238Pu, 241Am, 90Sr, and 137Cs are investigated in the Marche Region Central Italy. Mean values uncultivated soils (0.721 +/- 0.456, 0.023 0.014, 0.241 0.165, 5.40 3.32, 62.3 33.9 Bq kg(-1), respectively) 3.5-8 times higher than corresponding cultivated (0.147 0.054, 0.005 0.002, 0.047 0.021, 1.53 0.44, 7.70 2.07 kg(-1)). Radionuclide inventories ratios consistent with reported by United Nations Scientific Committee on Effect Atomic Radiation for this...
Essential and toxic elements (Al, Si, P, S, K, Ca, Ti, Mn, Fe, Ni, Cu, Zn, As, Br, Rb, Sr, Ba, Cd, Ce, Nd, Pb, U, Th, La) were determined by energy-dispersive polarized x-ray fluorescence spectrometry (EDPXRF) in 15 samples of clay materials for pharmaceutical cosmetic use. The investigated grouped according to their mineralogical composition powder diffraction (XRPD). Samples consisting smectites showed the lowest content La, Th highest quantity U. sample containing smectite kaolinite...
Essential and toxic elements were determined by inductively coupled plasma–atomic emission spectrometry (ICP-AES), mass (MS), atomic absorption (AS) in meat of 14 migratory birds originating from central northern Europe to provide baseline data regarding game consumed Italy. In all samples analyzed, cobalt (Co) chromium (Cr) (total) levels <0.326 mg/kgww. For nonessential or elements, arsenic (As), barium (Ba), cadmium (Cd), stannous (Sn), thallium (Tl), tellurium (Te), titanium (Ti), cerium...
The aim of this study was to determine background levels natural radionuclides such as uranium isotopes, (210)Pb, (210)Po, and (40)K in mussels Mytilus galloprovincialis, collected the central Adriatic Sea along Marche region a mechanism establish biomonitoring model for human radiation exposure resulting from ingestion species. This mussel is an invasive warm-water species largely consumed by local population also exported different countries. Among radionuclides, alpha emitters are...
Activity concentrations of ²¹⁰Po, ²¹⁰Pb, and ⁴⁰K were measured in different samples marine organisms from the central Adriatic Sea. The purchased local consumer market during all four seasons year to evaluate spatial temporal distribution natural radioactivity. concentration trend is following: > ²¹⁰Po ²¹⁰Pb. ranged between 54.9 235.9 Bq kg⁻¹ fresh weight, arithmetic mean Pb for <0.7 weight. Po activity 0.3 44.6 weight; its was 5.7 ± 7.2 Among pelagic species, anchovy displayed highest...
