Abstract The aim of this research was to assess the concentration of lead and zinc in chosen medicinal plants obtained from recreational areas of Katowice as well as to compare the phytoaccumulation properties of these plants. Lead and zinc concentration in plants and soil was indicated with flame and flameless atomisation atomic absorption spectroscopy AAS method. Phytoaccumulation properties of examined plant species were compared using the coefficients: enrichment factor, phytoaccumulation factor and coefficient of specific relative accumulation.

Aim: The major aim of this study is to compare Zinc (Zn) concentration present in human seminal plasma of asthenospermia (motility issues) and normospermia semen samples for identification of clinical relevance. Materials and Methods: Semen samples of normospermia (N=75), asthenospermia (N=75) were collected and semen analysis report has been done by standard world health organization protocol. Zn concentration was evaluated by using atomic absorption spectroscopy (AAS) for both the groups by using standard protocol. Results: Independent sample T-test on fertile and infertile men (asthenospermia and normospermia group) reveals that the zinc concentration is statistically insignificant (P=0.367). Zinc concentration was found to be high in normospermia (mean 2.5 mg/ml) over asthenospermia (mean 0.90 mg/ml) samples. Conclusion: Zn being an essential element for normal functioning for fertilization, its absence or less concentration may lead to infertility. We found high concentration of Zn in normospermia which reflects normal conditions for fertilization and less concentration in asthenospermia reflecting infertile conditions.

Abstract A new technique in atomic absorption spectroscopy is described, which replaces the use of a flame. Samples are injected into a cavity drilled transversely through a carbon rod, and subsequently dried, ashed, and atomized by the application of electric current. The resulting brief absorption signal is recorded and compared with standards. The procedure is particularly suitable for biological work since sample volume requirements are in the submicroliter range. The samples require no pretreatment. The method has given excellent results initially when applied to the measurement of magnesium, iron, copper, lead, and zinc in blood and plasma.

Abstract An X-ray fluorescence spectrometry (XRF) method was developed and validated for determination of chromium in FD&C Blue No. 1. Results of this analysis were compared with those obtained with an atomic absorption spectroscopy (AAS) method currently used by the U.S. Food and Drug Administration. Levels of Cr, as determined by the XRF and AAS methods, were comparable. The limit of quantitation for the XRF method is 4 μg Cr/g. The predicted 95% confidence interval at the specification level is 50 ± 5 μg/g.

The presence of some chemical compounds at higher levels than maximum permissible concentrations (MPC) in the drinking water, suggests of water resources pollution. In this paper the following elements were analyzed: total arsenic, cadmium, lead, cooper and zinc. Twelve samples of water from the water supply system from the city of Skopje were examined during one year from three different springs. Also, ten samples of bottled water from three producers from the Macedonian market were tested.The determined average mass concentrations of total As, Cd(II), Pb(II), Cu(II) and Zn(II) in the analyzed water samples from the water supply system are 1.35 μg/l, 0.06 μg/l, 0.6 μg/l, 0.9 μg/l and 1,12 μg/l, respectively, and for the tested bottled water, the mean values ranges from 0.56 - 0.83 μg total As / l, 0.053 - 0.056 μg Cd(II)/l, 0.51 - 0.54 μg Pb(II)/l , 0.6 - 0.87 μg Cu(II)/l and 0.68 - 0.8 μg Zn(II)/l water.The following instrumental analytical methods and techniques were used for the analysis of the tested samples of drinking water: flame atomic absorption spectroscopy (AAS), atomic absorption spectroscopy with hydride cеll, electrothermal atomic absorption spectroscopy.The obtained results are shown in tables and graphic form. According to the obtained results a comparative analysis was carried out indicate that it is a water of good quality that can be used in different branches of the process industry.The obtained results in this paper do not exceed the values of the MPC of the Republic of Macedonia prescribed by the legal regulations for the drinking water, which confirm the health safety of the drinking water from the water supply system in the city of Skopje and the packed waters from the Macedonian market in relation to the tested elements.
