Three garden vegetables—radish, carrot and lettuce—were cultivated in a pot experiment using two soils from the Příbram area polluted mainly by cadmium (Cd), zinc (Zn), lead (Pb) chromium (Cr). The of district, Czech Republic, are heavily as result atmospheric deposition toxic elements originating historic lead–silver mining smelting activities. results showed that lettuce absorbed highest amou...

In this study, the chemical profile of bee pollen (BP) and bread (BB) samples collected from same beehive were analyzed by LC–MS/MS (liquid chromatography technique coupled with tandem mass spectrometry), providing identification 23 phenolic compounds 42 free amino acids (FAAs). Rutin was compound highest rate occurrence in both BP BB samples. However, concentrations protocatechuic acid, 2,5-di...

Abstract In this work, Fe3O4-graphene oxide nanocomposite (GO-Fe3O4) was prepared as effective absorbent for magnetic solid phase extraction (MSPE) of trace quantities of cadmium ions in environmental water and rice samples using 1, 2-dihydroxy anthraquinone-3-sulphonic acid, sodium salt (Alizarin red S) and flame atomic absorption spectrometry (FAAS). The   GO-Fe3O4 was characterized by scanni...

The purpose of this study was to evaluate the effect of copper and silver in the plants on the mining area and the ingredients of essential oils. Plants collected from the same family, but they were collected randomly from various regions. The concentration of heavy metal in plant samples collected from Veshnave, Qom, Iran have been determined by Flame Atomic Absorption Spectrometry (FAAS). The...

Over 90 hair samples were collected from 67 healthy males and 26 healthy females in Silesia, Poland. The samples were analysed with DPASV for the simultaneous determination of several elements and with FAAS for all elements after wet digestion. The average values of element concentrations in the hair samples are presented. We observed that the hair of males showed consistently higher levels of ...

a simple, selective and efficient solid phase extraction method based on the use of  γ-alumina nanoparticles coated with sodium dodecyl sulfate (sds) and modified with 2-​(5-​bromo-​2-​pyridylazo)​-​5-​(diethylamino) ​phenol (5-br-padap) as a new adsorbent was developed for the separation and preconcentration of trace amounts of manganese (ii) prior to determination by flame atomic absorption s...
