“…It was investigated that one pack of cigarettes deposits 2-4 Rg Cd and 1-2 Rg Pb and Ni into the lungs of a smoker, whereas some of the smoke passes into the air to be inhaled by smokers and nonsmokers alike [41]. It was also consistent with another study that smokers generally exhibit significantly higher Cd, Ni, Pb, Fe, and Cu body burdens than nonsmokers, while smoking with alcohol consumption enhance the Cd, Ni, Pb, Fe, and Cu absorption and accumulation in all the tissues [33]. The results suggested that although these toxic elements (Cd, Ni, and Pb) pose a hazard to essential trace metal homeostasis of various organs, co-exposure can pose a major threat, while consumption of ethanol may absorb much more Cd and Pb than their unexposed counterparts [42].…”

“…ICP-AES also offers rapid, multielement determinations. The sensitivity of ICP-AES is lower than that of either Inductively coupled plasma mass spectrophotometer (ICP-MS) or atomic absorption graphite tube atomizer (AA-GTA), but ICP-AES can handle higher levels of total dissolved solids (TDS) than ICP-MS and is much faster than AA-GTA [33,34]. Since ICP-AES is able to analyze samples with higher TDS, more concentrated solutions can be prepared allowing trace elements to be measured.…”

The incidence of hypertension has been associated to cigarette smoking and consumption of alcohol. In the present study, trace and toxic elements were determined in scalp hair of patients diagnosed with hypertension who are smokers and habitual alcohol drinkers living in Dublin, Ireland. These results were compared with age-and sex-matched healthy, nonsmokers, nondrinking controls. The concentrations of trace and toxic elements were measured by inductively coupled plasma atomic emission spectrophotometer after microwave-assisted acid digestion. The validity and accuracy of the methodology were checked using certified reference material (NCS ZC 81002b) and by the conventional wet acid digestion method on the same certified reference material and on real samples. The recovery of all the studied elements was found to be in the range of 97.5%-99.7% in certified reference material. The results of this study showed that the mean values of cadmium, copper, iron, nickel and lead were significantly higher in scalp hair samples of both smoker and nonsmoker hypertensive patients than referents (P<0.001), whereas, the concentration of zinc was lower in the scalp hair samples of hypertensive patients of both genders. The deficiency of zinc and the high exposure of trace and toxic metals as a result of cigarette smoking and alcohol consumption may be synergistic with risk factors associated with hypertension.

“…A comparison of the proposed co-precipitation procedure in this study with the other reported preconcentration methods for cadmium, nickel, chromium, lead and cobalt ions extraction from water samples are shown in Table 4 (Bulut et al 2010;Feist and Mikula 2014;Soylak and Aydin 2011;Soylak et al 2007Soylak et al , 2008Tuzen and Soylak 2009). Using similar precipitate dissolving media (HNO 3 ), the coprecipitation procedure for metal ions with 8-hydoxyquinoline as a ligand yielded low precipitation factor (PF) compared to those reported in the literatures for which other ligands were used (Table 4).…”

“…Organic and inorganic co-precipitants have been reported for co-precipitation of heavy metal ions at trace levels from environmental samples (Elci et al 2003). Inorganic ligands reported as co-precipitants in literatures were hydroxide, thiocyanate, phosphates and organic ligands were dibenzyldithiocarbamate, N-benzoyl-N-phenyl-hydroxylamine, 2-nitroso-1-napththol-4 sulfonic acid (Chen et al 1997;Depecker et al 2009;Tuzen and Soylak 2009;Uluozlu et al 2010;Vircavs et al 1994;Zhang et al 2010).…”

Co-precipitation procedure has widely been employed for preconcentration and separation of metal ions from the matrices of environmental samples. This is simply due to its simplicity, low consumption of separating solvent and short duration for analysis. Various organic ligands have been used for this purpose. However, there is dearth of information on the application of 8-hydroxyquinoline (8-HQ) as ligand and Cu(II) as carrier element. The use of Cu(II) is desirable because there is no contamination and background adsorption interference. Therefore, the objective of this study was to use 8-HQ in the presence of Cu(II) for coprecipitation of Cd(II), Co(II), Cr(III), Ni(II) and Pb(II) from standard solutions and surface water prior to their determinations by flame atomic absorption spectrometry (FAAS). The effects of pH, sample volume, amount of 8-HQ and Cu(II) and interfering ions on the recoveries of metal ions from standard solutions were monitored using FAAS. The water samples were treated with 8-HQ under the optimum experimental conditions and metal concentrations were determined by FAAS. The metal concentrations in water samples not treated with 8-HQ were also determined. The optimum recovery values for metal ions were higher than 85.0%. The concentrations (mg/L) of Co(II), Ni(II), Cr(III), and Pb(II) in water samples treated with 8-HQ were 0.014 ± 0.002, 0.03 ± 0.01, 0.04 ± 0.02 and 0.05 ± 0.02, respectively. These concentrations and those obtained without coprecipitation technique were significantly different. Coprecipitation procedure using 8-HQ as ligand and Cu(II) as carrier element enhanced the preconcentration and separation of metal ions from the matrix of water sample.

Background: 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 hypertension incidence in population living in Dublin, Ireland is investigated. Methods: The different brands of cigarette (filler tobacco, filter and ash) consumed by the studied population were analyzed for cadmium (Cd), nickel (Ni), and lead (Pb). The concentrations of TEs in biological samples and different components of cigarette were measured by inductively coupled plasma atomic emission spectrophotometer after microwave-assisted acid digestion. The validity and accuracy of the methodology were checked using certified reference materials. Results: The filler tobacco of different branded cigarettes contains Cd, Ni and Pb concentrations in the ranges of 1.73-2.02, 0.715-1.52 and 0378-1.16 pg/cigarette, respectively. The results of this study showed that the mean values of Cd, Ni and Pb were significantly higher in scalp hair and blood samples of hypertensive patients in relation to healthy controls, while the difference was significant in the case of smoker patients (p < 0.001). The levels of all the three TEs were 2-3 folds higher in scalp hair and blood samples of non-hypertensive smoker subjects as compared to nonsmoker controls. Conclusion: The high exposure of toxic metals as a result of cigarette smoking may be synergistic with risk factors associated with hypertension.
