“…In our study none of these products were used by the study population and also all samples were washed according to the procedure recommended by the IAEA Advisory Group 15. Higher level of hair Zn in smokers44 and higher level of hair Se in non‐smokers45 were reported in the literature. In our study, when the subjects were classified according to exposure to smoking at home, there was no association between the exposure to smoking and hair Zn and hair Se levels.…”

The prevalence of asthma and other allergic diseases has increased markedly in the last few decades. Oxidative stress plays a central role in asthma pathogenesis, and reduced daily consumption of antioxidants is positively correlated with increased risk of asthma. Zinc (Zn) and selenium (Se) are the main antioxidant elements. In our study, we aimed to investigate hair Zn and Se levels in children with recurrent wheezing. The study included 65 patients with recurrent wheezing (RW) and 65 healthy children (HC). The hair Zn and Se levels (µg/g) of the RW group were lower in comparison with the HC group (162.43 ± 91.52 vs. 236.38 ± 126.44, P < 0.001, and 217.37 ± 83.01 vs. 280.53 ± 122.73, P < 0.001, respectively). Total antioxidant capacity (TAC) (mmol/L) of the RW group was found to be significantly lower in comparison with the HC group (1.38 ± 0.14 vs. 1.53 ± 0.20, respectively; P < 0.001). Number of wheezing episodes in the last 6 months were negatively correlated with serum TAC, hair Zn, and Se levels in RW group (r(p) = -0.291, P = 0.001; r(p) = -0.209, P = 0.017; r(p) = -0.206, P = 0.019, respectively). The number of acute respiratory tract infection (ARTI) episodes in the last 6 months was negatively correlated with serum TAC and hair Zn levels (r(p) = -0.316, P < 0.001, and r(p) = -0.196, P = 0.025, respectively). In this study, we found that TAC, hair Zn, and hair Se levels were lower in children with RW than HC and negatively correlated with wheezing episodes in the last 6 months. Also body Zn and Se levels can be reliably measured in hair samples.

“…It was observed that the highest concentration of Zn (70.00 µg/g) was obtained in toenail of subject from iron welder workers. The levels of Pb 55.33 was highest in the toenail of subject from iron welding worker when compared to liquor users and non liquor users, such differences recorded might be attributed to exposure of subject working in iron welder workshop [22,23] . This indicates that the concentrations of metals in the body is a function of metal in the work environment, this was in line with the work of [24] .…”

Hair and nail samples were collected from different subjects with respect to sex, age of those working in iron welder workshop and liquor and non-liquor subject in Maiduguri Metropolis, Borno State, Nigeria for heavy metals determination. Sample collection and preparations were carried out using standard procedures. The levels of heavy metals (Copper (Cu), Zinc (Zn), Copper (Co), Manganese (Mn), Iron (Fe), Chromium (Cr), Cadmium (Cd) Arsenic (As), Nickel (Ni) and Lead (Pb)) were carried out using Atomic Absorption Spectrophotometer (AAS, Unicam 969). From the results of this study, Zn showed the highest concentrations while Cu showed the least levels. The results of the study showed that there was no contribution of liquor towards nail and hair metal concentrations. The levels of all the metals studied were significantly higher in the toenails compared to fingernails samples (p<0.05). Similarly, iron welding workers showed high concentrations of heavy metals when compared to liquor user. The levels of all the metals studied were statistically higher in male subjects compared to female subjects (p<0.05). The concentrations of heavy metals in nail samples were significantly higher when compared to hair samples. Significant levels of these metals in nail and hair samples indicate the presence of these metals in the environment and the workplace of the subjects. Since the present study reveals high levels of some heavy metals in hair and nail samples of iron welding worker volunteer. So there is instantaneous need for public awareness about the hazards of this occupation in order to enable these volunteer take necessary precautionary measures.

“…A análise de cabelo pode ser feita por uma variedade de técnicas analíticas para a determinação de níveis de elementos traço. Dentre os métodos analíticos mais comumente utilizados para determinar elementos na matriz de cabelo estão espectrometria de absorção atômica (AAS) (YUNG-YUEH et al, 2000;ÇAVDAR et al, 2002;KILIC et al, 2004), espectrometria de emissão atômica com plasma indutivamente acoplado (ICP-AES) (DOMBOVÁRI e PAPP, 1998;CHOJNACKA et al, 2006), espectrometria de massa com fonte de plasma indutivamente acoplado (ICP-MS) (MICKELEY et al, 1998;TORRENTE et al, 2005), emissão de raios-X por partícula induzida (PIXE) (HOSSEINI et al, 1996;CHIBA et al, 2003), fluorescência de raios-X (XRF) (MAN e ZHENG, 2002;CHIBA et al, 2003) e análise por ativação com nêutrons instrumental (INAA) (FAGHIHIAN e RAHBARNIA, 2002;MAN e ZHENG, 2002;SARMANI e ALAKILI, 2004;SAIKI et al, 2008;MOHAMMED et al, 2007). Os elementos determinados em cada uma destas técnicas estão descritos no item 2.4..…”
