Concentration Levels

The purpose of the current study is to analyze the concentration levels of selected trace metals: Ca, Cu, Fe, K and Zn in medicinal plant Moringa stenopetala grown in SNNPR, Ethiopia. A wet digestion procedure is used. Thus, the result showed that the concentrations of Ca, Cu, Fe, K and Zn in Moringa stenopetala grown in Gamo Gofa (Arbaminch) were;2.80±0.36, 0.866±0.134, 7.98±1.23, 3.02±0.63 and 84±0.92 mg/Kg, in Wolaita 3.28±0.28, 0.94±0.16, 7.13±1.32, 7.13±1.32 and 0.61±0.11mg/Kg and in Konso were; 2.97±0.67, 0.77±0.098, 6.79±0.73, 2.39±0.23 and 0.37±0.006mg/Kg respectively.

In this research the atomic absorption spectroscopy method (the correlation coefficient was 0.9995) was employed for determination of the content of heavy metal-manganese in panax pseudo-ginseng var. notoginseng, which was chosen as the sample. The optimum conditions of two pretreatments were researched independently. In the dry ashing, the optimized temperature and time are 600°C and 4~6 hours respectively, and the manganese content determined is 53.16 ug/g and the recovery rate of manganese added in sample is 98.64%. In the wet digestion, The HNO3-H2O2 digestion system is the best one, and the content was 52.95ug/g and the recovery rate is 97.30%. So the two pretreatment methods of the sample are accurate enough on manganese content determination. But the dry ashing is better than the wet digestion relatively.

Two new μ3-oxo trinuclear heterometallic Fe2IIICrIII complexes with furan-2-carboxylic and salicylic acids with the composition: [Fe2CrO(C4H3OCOO)6(CH3OH)3]NO3·0.5CH3OH and [Fe2CrO(C6H4(OH)COO)7(CH3OH)2]·2DMA were synthesized starting from iron(III) and chromium(III) salts mixture. The complexes structures were confirmed by elemental analysis, IR, Mössbauer spectroscopies, and X-ray analysis. The atomic absorption spectroscopy confirmed that the iron: chromium ratio is 2:1. The thermal properties of both heteronuclear complexes have been investigated in oxidizing and inert atmospheres revealing the stability of the trinuclear core up to 170 and 220°C, respectively.

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.

Abstract Original carbonaceous material of fossile carbon plants from the divisions of the Equisetophyta (Calamariaceae), Lycophyta (Lepidodendraceae, Sigillariaceae), Filicophyta (Filicatae), and Spermatophyta (Pteridospermatae, Cordaitidae) was analyzed by atomic absorption spectroscopy on its content of the trace metals vanadium and nickel. The average V-content was found to be 10 to 100 fold higher than that of the neighbouring coal beds or that of the embedding materials, while the Ni-concentrations were found to be almost in the same range. The highest contents of V and Ni were found in the Calamariaceae and in the Pteridospermatae. The V-and Ni-contents of the fossile carbon plants are compared to those of related recent plant genera (clubmosses, horse­ tails, ferns), which were analyzed by 46 representative samples. A possible biogenous enrichment of V and Ni in plants of the carbon age is discussed.

This study determined the concentration of zinc, lead and cadmium in tomatoes consumed in some areas of Uasin Gishu, Kenya. Samples were taken in quintuplicate from Huruma and Bahati estates (Eldoret) and Chebaiywo (Kesses) and their metalliferous content were determined by atomic absorption spectroscopy. All samples had detectable levels of trace metals, with lead recording the highest concentration of 43.20 ± 0.31 mg/kg. Zinc concentrations were below WHO guidelines. Daily intakes ranged from 8.25 × to 2.59 × mg/kg/day. Though there are no probable cancer risks, hazard quotients indicated that deleterious health effects could arise from daily consumption of tomatoes.
