“…Similar results in term of specific profiles in hair levels of toxic and essential trace elements related to different working processes were recovered by the same authors in workers involved in different departments of a petrochemical plant [28]. Also, Nouioui et al [29] evaluated the hair levels of essential and toxic elements of a sample of workers in a Pb battery manufacturing plant and the influence of some confounding factors (age, work activity, and lifestyle habits) on hair elements' levels. They demonstrated that age, the type of work activity, and smoking significantly impact on the level of some elements in hair samples.…”

The aim of the study was to evaluate occupational exposure to 40 elements among a group of Eritrean adults employed at the Medeber metal market by analysing human scalp hair samples and by investigating the role of some predictors (gender, age, and body mass index-BMI) on their levels. Scalp hair samples were collected from 60 subjects (32 subjects working at the Medeber metal market and 28 subjects not working at Medeber and not employed in other industrial or artisanal activities) and were analysed through inductively coupled plasma mass spectrometry to determine the contents of 40 major and trace elements. Information on participants was collected via questionnaire. Significant differences were found in the hair levels of certain elements between subjects working at the Medeber metal market and subjects not exposed. In particular, working at the Medeber metal market increased hair levels of Be, B, Cu, Zn, Mo, Cd, Sb, Tl, Pb, and Fe from 25 to 100%, while reduced Na, K, and Rb levels from 30 to 50%. With multivariate adjustment for age, gender, and BMI, the results confirm that working at Medeber significantly increased the hair levels of Cu, Zn, Sb, Pb, and Fe. This finding reveals the need for more accurate and routine biomonitoring surveys and the necessity of health promotion campaigns both for local decision-makers and workers to increase health promotion and safety in this workplace.

“…Nonetheless, contact of the hair with the secretions of sebaceous, apocrine and eccrine glands can contribute to the elemental profile and, probably, for this reason significant correlations between concentrations in hair and elemental intakes are usually low (Combs 1987). Environmental pollution too has been reported to affect element concentrations in the hair (Combs 1987;Nouioui et al 2018;Stepanova et al 2018;Długaszek 2019).…”

The aim of the study was to investigate element concentrations in the hair of growing and adult dogs. Overall, 39 dogs were recruited in a kennel, split in 4 groups: G1, 10 puppies of small size breeds; G2, 6 puppies of medium size breed; G3, 11 adult dogs of medium size breeds; G4, 12 adult dogs of toy breeds. The dogs of each group were fed 4 different complete diets, according to the requirements. Hairs were sampled at the beginning of the study (D0) and after 60 days (D60). Elements were analysed in triplicate using ICP-OES. In the hair of the adult dogs of the G3 group the concentration of Al (p < .01) was lower and in the G2 group the concentration of Zn was higher (p < .01) than in the other groups. Cu and Mn concentrations in the hair were higher (p < .01 and p < .05, respectively) in puppies fed G1 and G2 diets in comparison to adult dogs fed G3 and G43 diets. Hair concentrations of K, Li and Na were higher at D60 in comparison with D0 (p < .01). Correlations between concentrations in the hair of Al and Fe, Al and Mg and Fe and Mg were highly significant (p < .01). Present data do not support the use of element concentrations in the hair to assess their nutritional supply but, likely, they can be used in relation to physiological status of the animals. Further studies are required to investigate the factors affecting element concentrations in the hair of dogs. HIGHLIGHTS Concentrations of Cu, Mn and Zn in the hair differed between growing and adult dogs; Al concentration in hair was highly correlated with Fe and Mg; Several factors other than nutritional supply regulate element deposition in the hair ARTICLE HISTORY

“…Our patient did not have dental amalgama fillings [26] but ate fish regularly 1-2 times/week so potential mercury exposure was modest. A hair analysis could be of aid for chronic heavy metal toxicity screening [19]. Our patient also presented abnormal plasma lipoproteins and laboratory signs of hepatotoxicity: these are other possible side effects of anabolic steroids abuse [27].…”

“…The severity of these subclinical alterations was directly correlated with the mean dosage [19] and duration of AASs abuse [20]. A recent cross-sectional cohort study compared a group of male weightlifters who had used AASs (86 men) in the last two years with a group (54 men) with no history of abuse:…”
