“…However, urine and hair have also been suitable samples to measure occupational and environmental exposure to manganese (40). Some studies indicated that hair and nail could be used as biomarkers of manganese exposure (45). However, Balachandran et al's study on hair as a manganese exposure biomarker revealed no significant relationship between manganese exposure and hair manganese concentration (46).…”

Background: Manganese (Mn) is an essential element for the human body, but it can cause adverse effects on the Central Nervous System at high doses. Exposure to manganese fumes during welding can harm welders' health. Objectives: The current study aimed to measure manganese produced by shielded metal arc welding (SMAW) in the breathing zone air and blood of welders and investigate the relationship between manganese concentrations in air and blood. Methods: In this descriptive-analytical cross-sectional study, 35 welders were enrolled as the exposed group and 40 office workers as the control group. Manganese concentration in air was measured according to NIOSH method 7301. Air and blood sample analyses were carried out by ICP-OES. Statistical analysis was performed with MINITAB 17. Data were analyzed using Pearson correlation coefficient, one-sample t-test, paired t-test, and logistic regression. The significance level was set at P < 0.05. Result: The mean concentration of welding respirable particles and manganese fumes were 9.56 ± 1.67 and 0.45 ± 0.08 mg/m3, three and 22 times the exposure limit recommended by ACGIH, respectively. Average manganese was significantly higher in the welders’ blood (0.16 ± 0.02 µg/mL) than in the controls’ blood (0.04 ± 0.002 µg/mL). There were strong and significant correlations between the welding respirable particles and manganese concentration in welders’ breathing zone and blood manganese levels. Also, with each year of work experience, the manganese concentration in the welders’ blood increased by 1.5%. Conclusions: Welders are at risk of contamination with manganese. Manganese exposure reduction through more efficient ventilation systems, reducing welder’s exposure time, staff training, and appropriate respiratory protection equipment should be applied to reduce manganese exposure among welders and prevent health complications.

“…This cyclical behavior leads to scenarios of chronic and/or acute intoxication via ingestion, inhalation, and dermal contact mechanisms [3]. As a result, the accumulation in the body and the affectation of organs and glands such as the heart, brain, kidneys, bones, and liver, among others [3][4][5][6]. This situation has worsened in developing countries that have increased their industrial activities and, therefore, the availability and use of products with a high content of heavy metals, which is affecting the current population [3].…”

Validation of an Analytical Method for the Determination of Manganese and Lead in Human Hair and Nails Using Graphite Furnace Atomic Absorption Spectrometry

et al. 2022

This article describes the validation of analytical methods for the determination of Manganese (Mn) and lead (Pb) by graphite furnace atomic absorption spectrometry (GFAAS) in human hair and nail samples. Method validation parameters such as linearity, repeatability, reproducibility, and precision were determined. In addition, the limit of detection (LOD), the limit of quantification (LOQ), and measurement uncertainty were calculated. The developed method was linear in the concentration ranges of 0.001–0.015 and 0.002–0.020 µg·L−1 of Mn and Pb, respectively. The determination coefficients obtained were greater than 0.995. The recoveries obtained after the addition of the standard concentration for the metals ranged from 84.80–107.98%, with a precision not exceeding 12.97% relative standard deviation. The calculated LOD and LOQ for Mn and Pb are within the ranges established by Commission Regulation (EU) No. 836/2011. The expanded uncertainty was estimated to be less than 9.93–6.59% for Mn and Pb. Matrix effects were also studied, finding a smooth effect in both matrices. The analysis of 30 samples of each type revealed the presence of Mn in 30 and Pb in 13 samples. Overall, the proposed validation method was considered optimal for the determination of Mn and Pb.

“…Environmental pollution has an important role in increasing the levels of toxic and heavy metals in the human body, which lead to various chronic diseases (Rajfur et al, 2018;Silva et al, 2018;Ocelić Bulatović et al, 2019;Cabar et al, 2020;Noreen et al, 2020;Almeida-da-Silva et al, 2021;Ikese, et al, 2021;Wu et al, 2021;Lotah, 2022). The working environment has come to play an important role in this subject, due to the direct relationship between man and the degree of hazards chemical agents present in their workplace environment.…”

“…In addition, each workplace environment is not unique but also in the degree of hazards it poses to the workers. Furthermore, the pollution of the workplace environment with toxic heavy metals is a worldwide problem (Lemos & De Carvalho, 2010;Massadeh et al, 2010;Amartey et al, 2011;Peter et al, 2012;Vincenti et al, 2013;Momčilović et al, 2016;Alrobaian & Arida, 2019;Al-Muzafar et al, 2021;Ikese, et al, 2021;Lotah et al, 2022). In this context, toxic and heavy chemicals come out in the workplace environment from various uses in the form of spray or dust, which can get into the body of workers mainly either through inhalation and/or dermal contact.…”
