“…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.

“…According to the Environmental Protection Agency (EPA), human hair is one of the most important biological materials for worldwide environmental monitoring and the International Atomic Energy Agency uses hair to monitor global trends of element levels [36]. Hair as a biological tissue is unique in respect that it serves as an accumulator for trace elements, and in addition, it is formed in relatively short period of time and remains isolated from the metabolic events in the human body and its metal content can reflect the body status for a long period [34,37,38]. Once mercury has been accumulated into the hair, its concentration does not change significantly, whereas mercury contents in blood and urine can only reflect very recent exposures [39].…”

This study investigates mercury, lead, copper, and zinc concentrations in six most frequently consumed fish species (120 samples), sediments (20 samples) taken from Karaduvar Fishing Area where fish species live, and Mersin Port as a contrary region, and human scalp hair for people regularly consuming these fish species (50 samples) and non-fish-eaters (15 samples) in Mersin, Turkey. On taking living environment into account, the fish groups include pelagic species of Liza saliens, Liza aurata, and demersal species of Merluccius merluccius, Mullus barbatus, Upeneus moluccensis, and Solea solea. Total Hg (THg) was found to accumulate in muscle tissues at the lowest concentration (0.01 microg/g) in L. saliens and at the highest (2.66 microg/g) in S. solea. Pb was only detected at high concentrations of 1.86 microg/g in M. barbatus and of 2.16 microg/g in M. merluccius. Cu and Zn concentrations were below the detection limit within all fish species. In the sediment samples, Pb and Cu concentrations were persistently below their effect range-median (ERM) value, whereas this limiting value only maintained for 15% of THg concentrations. On the other hand, the effect range-low (ERL) of sediment exceeded at Pb in 15% of samples and Cu in 25% of samples. Zn remained below the detection limit for sediment samples. The metal concentrations at scalp hairs of regular consumers of these fish groups and non-fish eaters vary from the range 0.40-3.28 to 0.14-1.02 microg/g for THg, 11.16-107.84 to 8.00-22.38 microg/g for Pb, and 151.67-645.35 to 144.92-343.50 microg/g for Zn. An important finding of the present study is the significant adverse impact of sedimentary heavy metal bioaccumulation to human through the consumption of demersal fishes in the city of Mersin along the southern coast of Turkey.

“…For example, hair mercury concentration was shown to be a reliable biomarker for methylmercury exposure [5]. Other elements have been also measured in hair and references values have been proposed in specific populations [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] However, the use of hair analysis has several limitations. One problem relies in the difficulty to distinguish between endogenous (absorbed into the blood and incorporated into the hair) and exogenous contamination (derived from external contamination) [23,24].…”

Severe polymetallic contamination is frequently observed in the mining communities of Bolivian Altiplano. We evaluated hair trace elements concentrations at the population level to characterise exposure profile in different contexts of contact with mining and metallurgical pollution. We sampled 242 children aged 7 to 12 years in schools from five Oruro districts located in different contexts of potential contamination. Hair trace elements concentrations were measured using ICP-MS (Pb, As, Hg, Cd, Sb, Sn, Bi, Ag, Ni, Se, Cu, Cr, Mn, Co and Zn). We compared concentration according to school areas and gender. Concentrations were markedly different depending on school areas. Children from schools near industrial areas were far more exposed to non essential elements than children from downtown and suburban schools, as well as the rural school. The most concentrated non-essential element was Pb (geometric means (SD): 1.6 (1.3) µg/g in rural school; 2.0 (2.3) µg/g in suburban school; 2.3 (3.0) µg/g in downtown school; 14.1 (2.7) µg/g in the mine school and 21.2 (3.3) µg/g in the smelter school). Boys showed higher levels for all non-essential elements while girls had higher levels of Zn. Hair trace elements concentrations highlighted the heterogeneity of exposure profiles, identifying the most contaminated districts.
