Abstract The aim of the research was to evaluate the accumulation level of copper, zinc and nickel in forest mushrooms – Bay Bolete (Xerocomus badius), Saffron Milk Cap (Lactarius deliciosus), Rough-Stemmed Bolete (Leccinum scabrum), Slippery Jack (Suillus luteus) and Parasol Mushroom (Macrolepiota procera). The analysed mushrooms were obtained from growth forests located in the Masovian Voivodeship in the following counties: Siedlce, Sokołów, Łosice and Łuków. Total content of metals was determined using the method of atomic emission spectroscopy with inductively coupled plasma, after the earlier mineralisation of materials ‘by dry combustion’ in a muffle furnace at the temperature of 450°C, and after melting of ash in a 10% solution of HCl. In the soil samples taken from the places where the tested mushrooms occur, pH in 1 mol KCl·dm-3 and total content of copper, zinc and nickel were determined by the ICP-AES method after earlier mineralization in mixture of concentration HCl and HNO3 (3:1) in a microwave system. Test results were statistically analysed with the use of software STATISTICA 12 PL (STATSOFT, TULSA, USA). The analysed mushrooms had diverse content of the determined metals. The highest total average content of copper and zinc was present in Bay Bolete: 34.83 mg ∙ kg-1d.m. for Cu and 155.50 mg ∙ kg-1d.m. for Zn, and the highest average content of nickel was contained in Rough-Stemmed Bolete – 2.98 mg ∙ kg-1d.m.. The lowest average content of copper and zinc was determined in Rough-Stemmed Bolete: 11.98 mg ∙ kg-1d.m. for Cu and 91.90 mg ∙ kg-1d.m. for Zn, and lowest total average content of nickel was present in Bay Bolete – 1.05 mg ∙ kg-1d.m. No excessive accumulation of examined heavy metals was stated in the analysed mushrooms species.

In order to determine the contents of cadmium, copper, zinc, and lead in leaves, stalks, and root of Rhizophora mangle, samples from three parcels located in the river Sevilla mouth – Ciénaga Grande de Santa Marta, were taken in October 2003. Measures of metals concentrations were made through the Inductively Coupled Plasma Atomic Emission Spectrometry technique (ICP–AES). The results indicated that lead concentration in R. mangle organs was below method detection limit (<2.38 μg/g) except the absorbent root (16.3 μg/g); and significant differences exist in the contents of cadmium, copper, zinc, and lead into R. mangle organs, following this concentration order: absorbent roots > stalk > young leaves > adult leaves > aerial roots.

Experiments have shown that 1,4,7,10,13,16-hexathiacy clooctadecane (L3) increased the Cu2 toxicity on HepG2 cells, whereas the combination Zn2 /L3 was less toxic relative to the metal control. In all cases, glutathione (GSH) levels were decreased and vitamins C and E supplementation partially counteracted the increased toxicity in the Cu2 /L3-treated cells. The previously observed effects of this hexathiamacrocyclic ligand (L3) on the Cu2 and Zn2 toxicity were further investigated by first depleting the intracellular GSH levels by means of L-buthionine S,R-sulphoximine. Combined treatment with Cu2 /L3 resulted in complete cell death, whereas for Zn2 /L3 no severe effects were observed. Direct measurement of reactive oxygen species (ROS) revealed that Cu2 induced a high degree of oxidative stress on the cells. This was not the case for Zn2. The results proved a previously proposed mechanism in which GSH is used to conjugate the metal–ligand complex, but as a result of this, GSH is no longer available for inactivation of ROS. Also, both the intracellular copper and zinc content were determined for each experiment by means of inductively coupled plasma–atomic emission spectroscopy. According to these data, zinc is depleted in Cu2 /L3-treated cells, which could have consequences on superoxide dismutase and as a result of this on the amount of oxidative stress.

Abstract We describe an inductively coupled plasma atomic emission spectrometer that has been adapted to perform routine, simultaneous, direct analyses of calcium, magnesium, copper, zinc, and iron in serum or urine without sample digestion or pretreatment. The system, constructed with inexpensive, readily available components, can analyze 1-mL or smaller samples. Results correlate nearly perfectly with those derived by standard atomic absorption techniques (r = 0.98 to 0.997). Using certified serum and urine samples from various sources, we demonstrate that the instrument yields accurate results with a precision better than certified values. The instrument is sensitive to one order of magnitude less than the lower limit of the normal range in serum or urine for all elements tested, and responds linearly to concentrations two orders of magnitude higher than the upper limit of the normal range. With the system described here, these five elements can be assayed with the same or less technical effort than needed for a single element by atomic absorption.

AbstractIn this study, seven pretreatment methods for chromium speciation in tanned leather were evaluated: acidic mineralization, ethylenediaminetetraacetic acid (EDTA) extraction, diethylenetriaminepentaacetic acid (DTPA) extraction, alkaline extraction (NH4OH), ammonium nitrate extraction (NH4NO3), water extraction, and phosphate buffer extraction. Acidic mineralization permitted the decomposition of the organic matter and ensured the complete digestion of leathers, giving access to the total content of chromium in each sample using inductively coupled plasma-atomic emission spectrometry (ICP-AES). From all the extractant media tested, EDTA proved to be the most efficient, allowing the extraction of Cr(VI) and Cr(III) as a Cr(III)-EDTA complex, quantitatively. Method validation is presented for EDTA extraction and direct mineralization. For the EDTA extraction, method detection limit (MDL) and method quantification limit (MQL) for total Cr in leather were 3.4 ppb and 11.2 ppb (µg of total Cr per L of extraction solution), respectively. Due to the lack of leather certified reference materials (CRMs) for Cr(VI), accuracy was evaluated by spiking leather samples with a Cr(VI) solution. The spike recovery of EDTA microwave assisted extraction ranged from 91.0 to 108.6%. Interday precision was also evaluated and all variation coefficients were below 5%, for both mineralization and EDTA extraction. This article provides an efficient procedure to extract quantitatively chromium from leather, while maintaining the speciation, which can be further followed by ion chromatography-inductively coupled plasma-mass spectrometry (IC-ICP-MS).

Abstract Trace elements selenium, copper, and zinc are essential minerals for the human body. One of the means to increase the micronutrient content in diets is to add them to food raw materials, for example, to enrich grain with micronutrients during malt production. To obtain rye malt, 3 kg grain was soaked in 10 l water with addition of three mineral salts — sodium selenate (Na2SeO4), copper sulphate (CuSO4 5H2O), and zinc sulphate (ZnSO4 7H2O) at different concentrations and different combination of salts. The concentration of selenium, copper, and zinc was determined in rye malt. The obtained results were used to calculate the degree of assimilation of trace elements in rye malt. The interaction of trace elements selenium/copper and copper/zinc was studied. The total amount of selenium, copper, and zinc was analysed by inductively coupled plasma mass spectrometry (ICP-MS). Sample preparation for elemental analysis was performed by wet acid digestion in a closed microwave mineralisation system. The selenium assimilation degree in rye malt was within 10.6 to 12.2%. Accordingly, copper assimilation was 32.8 to 38.0% and zinc 49.3 to 57.0%. Simultaneous presence of selenium/copper and copper/zinc during rye grain soaking promoted the assimilation of each mineral, compared with only one mineral additive.

Background: This study aims to determine and compare the levels of trace elements copper, zinc, selenium and chromium in GCF and serum of patients with periodontitis and healthy individuals. Methods: This cross sectional study includes 24 study subjects recruited from the patients reporting to the Department of Periodontics , Tagore Dental College Chennai. All the selected patients were subjected to a clinical examination done by a single examiner. The estimation of trace elements Copper, Zinc, Selenium and Chromium in GCF and serum is performed using Perkin Elmer optima 5300 Inductively Coupled Plasma Emission Spectrometer (ICPOES). Results: GCF and serum copper levels showed no significant difference in both periodontitis and healthy groups . Selenium levels tend to be the same in both groups. Serum zinc levels are more in periodontitis patients than healthy subjects (p less than 0.01). GCF chromium levels are found to be more in patients with periodontitis than healthy. Conclusions : More research is therefore needed to monitor the role of these trace elements C with an increased sample size to ascertain whether they are associated with a reduced risk of periodontitis.
