Abstract In several series of 212 samples, higher fungi, especially from the genus Amanita and related genera, were analyzed by atomic absorption spectroscopy on their content of the trace metals vanadium and molybdenum. Only vanadium was found to be present in high concentration in the fly agaric mushroom (Amanita muscaria), while 22 of its related species showed the normal V-content of the higher fungi tested. A correlation with the presence of molybdenum could not be detected. A special enrichment of Mo was not found in higher fungi. The analysis of several fruit bodies from A. muscaria showed that the highest V-content was present in the bulb and in the lamellae, both contents increasing with age, while the spores contained only 1 - 2% of the lamellar vanadium.

Abstract In several series of 262 samples, Higher Fungi, especially from the Tremellales and Gastero-mycetes, were analyzed by atomic absorption spectroscopy on their content of the trace metals manganese and iron. Both elements were found to be present in higher concentrations in some species of the Tremellales and Phallales. In the case of wood-destroying fungi, the Fe-and Mn-contents of the substrates were compared to those of the corresponding fungi. Only the species with the highest level of these metals reached the same contents as their substrates or a poor enrichment. Among the remaining species of the Higher Fungi, only in the case of the epigean Phallales, a possible biochemical role of manganese has been discussed.

The increasing content of heavy metals in soil and atmospheric air can lead to serious consequences in the final link of which a person is. To determine heavy metals in atmospheric deposition, the method of biomonitoring of mosses was used. Joint Institute for Nuclear Research scientists started the implementation of the mosses biomonitoring methodology in Azerbaijan 2015. In total, the concentration was determined for 44 elements. Determinations were performed using instrumental analysis of Epithermal Neutron Activation and Atomic Absorption Spectroscopy in 85 moss samples. The species of moss used in the work was Pleurosium schreberi. Based on the analysis results, the most contaminated areas are identified.

Ambroxol hydrochloride (AMB), (1s,4s)-4-((2-amino-3,5-dibromocyclohexyl)methylamino) cyclohexanol hydrochloride, is semi - synthetic derivative of vasicine obtained from Indian shrub Adhatoda vasica. It is a metabolic product of bromhexin and it is used as broncho secretolytic and an expectorant drug. Analysis of Flavamed® tablets, in which ambroxol hydrochloride (AMB) is an active component, was performed. UV/VIS spectrophotometry and atomic absorption spectroscopy (AAS) were used. Direct and indirect UV/VIS spectrophotometric methods were used for quantitative analysis of AMB and the following recovery value results were obtained: 100,16% and 95,23%, successively. Content of heavy metals in Flavamed® tablets was determined by atomic absorption spetroscopy.

Excess trace metal contamination in vegetables is a growing concern globally. Plants can be contaminated by trace metals, and it is important to understand the degree of contamination and the inherent risk. Vegetables are a staple in human diets, thus knowing the level of concentration of these metals within the diet is increasingly important. This project is designed to assess levels of trace metals in vegetables using Atomic Absorption Spectroscopy. Atomic absorption spectroscopy (AAS) is an analytical technique that determines unknown concentrations of elements using absorption of light from the desired elements with the aid of the working calibration curve obtained from the series of standards. Tests were done on three different commonly vegetable available in the UK to identify whether levels of trace metals fall within safe levels for human consumption. The vegetables selected were carrots, potatoes, and tomatoes. The concentration within organic vegetables did not significantly differ from the non-organic ones, though the results show, in some cases higher concentration of chromium in the potato and carrot peel. This is worthy of note from a health and nutrition perspective especially for those people that have a deficiency of these trace metals in their body or conversely wanted to manage their intake. The mean concentrations of these metals are in decreasing order of >Pb>Cr in most vegetables but in some Cr>Pb. The good thing is that the concentrations of these metals in vegetables purchased in the UK all fall below the maximum limits set by WHO/FAO and are thus considered safe for human consumption.

More still needs to be learned regards the relative contamination of heavy metals and pesticide residues, particularly those found in widely consumed Nigerian food crops like cereals, vegetables, and tubers. In this current study, the heavy metals and pesticide residues detectable in widely consumed Nigerian food crops were respectively quantified using atomic absorption spectroscopy (AAS) and gas chromatography (GC). Specifically, the widely consumed Nigerian food crops included cereals (rice, millet, and maize), legume (soybean), tubers (yam and cassava), as well as leaf (fluted pumpkin, Amaranthus leaf, waterleaf, and scent leaf) and fruit vegetables (okro, cucumber, carrot, and watermelon). Results showed that the detected heavy metals included arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), iron (Fe), lead (Pb), manganese (Mn), mercury (Hg), and nickel (Ni), whereas the pesticide residues included Aldrin, Carbofuran, g-chlordane, Chlorpyrifos, DichloroBiphenyl, Dichlorodiphenyldichloroethane (DDD), Dichlorodiphenyltrichloroethane (DDT), Dichlorvos, Endosulfan, Heptachlor, Hexachlorobenzene (HCB), Isopropylamine, Lindane, t-nonachlor, and Profenofos. Across the studied food crops, the concentrations of heavy metals and pesticides were varied, with different trends as they largely fell below the established maximum permissible limits, and with some exceptions. Our findings suggest there could be a somewhat gradual decline in the concentration of the heavy metals and pesticide residues of these studied food crops when compared to previously published reports specific to Nigeria. To help substantiate this observation and supplement existing information, further investigations are required into the concentration of these heavy metals and pesticide residues specific to these studied food crops at other parts of the country.
