“…In very small amounts, it may be beneficial to activate some enzyme systems, but its toxicity at higher levels is more evident. However, nickel toxicity is not very common in humans because nickel absorption is very low (DIVRIKLI et al, 2006). In the present study the nickel content was in the range from 6.6 to 8.5 µg g -1 for the korarima seed samples and from 16.3 to 20.4 µg g -1 for the soil samples, and there was no significance difference between the levels of nickel determined at the different sites.…”

“…Copper is one of the essential micronutrients and its adequate supply for growing plants should be ensured through artificial or organic fertilizers (DIVRIKLI et al, 2006). In the present work, the copper concentration was from 5.8 to 8.3 µg g -1 in the korarima seeds and from 10.2 to 12.9 µg g -1 in the soil samples.…”

“…In foods cadmium is mostly derived from a variety of environmental contamination sources (DIVRIKLI et al, 2006). Currently there is considerable interest in Cd in plant nutrition and the cadmium levels in plant materials are in the range from 0.1 to 1.0 µg g -1 .…”

“…Manganese activates numerous essential enzymes and food contains trace amounts. Higher manganese concentrations were expected because it accumulates mostly in plant leaves and also because the absorption of soluble Mn increases with decreasing soil pH (DIVRIKLI et al, 2006;AJASA et al, 2004). A daily dietary intake of 2.5 to 5 mg of manganese by human beings contributes to the well-being of the cells.…”

Levels of selected essential and non-essential metals in seeds of korarima (Aframomum corrorima) cultivated in Ethiopia SummaryThe levels of essential (Ca, Mg, Fe, Zn, Cu, Co, Cr, Mn and Ni) and non-essential (Cd and Pb) metals were determined by flame atomic absorption spectrometry in samples of korarima (Aframomum corrorima) seeds and the corresponding soils collected from southern and southwestern Ethiopia. A wet digestion procedure involving the use of 3 mL of HNO 3 (69-72%) and 1 mL of HClO 4 (70%) were used to solubilize the metals from the korarima seed samples, and a modified aqua regia (HCl:HNO 3 ) reagent with added hydrogen peroxide (6 mL of aqua regia and 1.5 mL of H 2 O 2 ) was used for the soil samples. The levels of the nutrients in the korarima seed samples were in the following ranges: Ca (1794-2181); Mg (1626-2067); Mn (141-180); Fe (37-46); Zn (12-18); Ni (6.6-8.5); Cu (5.8-8.3); Cr (3.8-5.8) and Co (2.0-2.3) in µg g -1 , respectively. The concentration of non-essential cadmium was in the range from 0.9-1 µg g -1 while that of lead was below the detection limit of the method. There was good correlation between the levels of some metals (Ni, Fe, Cd, Ca, Cu, Mg) in the korarima seeds and soil samples but poor correlation between other metals (Cr, Zn, Mn, Co).

ResumoOs níveis dos metais essenciais (Ca, Mg, Fe, Zn, Cu, Co, Cr, Mn e Ni) e não essenciais (Cd e Pb) foram determinados por espectrometria de absorção atômica de chama em amostras de sementes de korarima (Aframomum corrorima) e também nos solos correspondentes colhidos no sul e sudoeste da Etiópia. Um procedimento de digestão úmida envolvendo o uso de 3 mL HNO 3 (69-72%) e 1 mL HClO 4 (70%) foi usado para solubilizar os metais das amostras de sementes de korarima, e um reagente de água-régia (HCl:HNO 3 ) modificada pela adição de peróxido de hidrogênio (6 mL de água-régia e 1,5 mL H 2 O 2 ) foi usada para as amostras de solo. Os níveis dos nutrientes nas amostras de sementes de korarima estavam nas seguintes faixas: Ca (1794-2181); Mg (1626-2067); Mn (141-180); Fe (37-46); Zn (12-18); Ni (6,6-8,5); Cu (5,3); Cr (3,8); e Co (2,0-2,3) em µg g -1 , respectivamente. A concentração de cádmio não essencial estava na faixa de 0.9-1 µg g -1 enquanto o valor para chumbo foi abaixo dos limites de detecção do método. Houve boa correlação entre os níveis dos metais Ni, Fe, Cd, Cu e Mg, nas sementes de korarima e nas amostras de solo, mas pouca correlação entre o restante dos metais (Cr, Zn, Mn, Co).

“…The main advantage of microwave-assisted sample pretreatment is its requirement of small amount of mineral acids and a reduction in the production of nitrous vapors (Divrikli et al 2006;Soylak et al 2007). Microwave systems keep blank levels low because only small volumes of reagents are required and allow more samples to be processed per hour than conventional digestion systems (Afridi et al 2006;.…”

Cigarette smoking interferes with the metal homeostasis of the human body, which plays a crucial role for maintaining the health. A significant flux of heavy metals, among other toxins, reaches the lungs through smoking. In the present study, the relationship between toxic element (TE) exposure via cigarette smoking and rheumatoid arthritis incidence in population living in Dublin, Ireland, is investigated. The trace {zinc (Zn), copper (Cu), manganese (Mn), and selenium (Se)} and toxic elements arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) were determined in biological (scalp hair and blood) samples of patients diagnosed with rheumatoid arthritis, who are smokers living in Dublin, Ireland. These results were compared with age and sex-matched healthy, nonsmoker controls. The different brands of cigarette (filler tobacco, filter, and ash) consumed by the studied population were also analyzed for As, Cd, Hg, and Pb. The concentrations of trace and TEs in biological samples and different components of cigarette were measured by inductively coupled plasma mass spectrophotometer after microwave-assisted acid digestion. The validity and accuracy of the methodology were checked using certified reference materials. The recovery of all the studied elements was found to be in the range of 96.4-99.8 % in certified reference materials. The filler tobacco of different branded cigarettes contains Hg, As, Cd, and Pb concentrations in the ranges of 9.55-12.4 ng, 0.432-0.727 μg, 1.70-2.12 μg, and 0.378-1.16 μg/cigarette, respectively. The results of this study showed that the mean values of As, Cd, Hg, and Pb were significantly higher in scalp hair and blood samples of rheumatoid arthritis patients as compare to healthy controls, while Zn, Cu, Mn, and Se concentrations were found to be lower in rheumatoid arthritis patients, the difference was significant in the case of smoker patients (p<0.001). The levels of four toxic elements were 2-3-folds higher in scalp hair and blood samples of nonrheumatoid arthritis smoker subjects as compared to nonsmoker controls. The high exposure of toxic metals as a result of cigarette smoking may be synergistic with risk factors associated with rheumatoid arthritis.
