Summary: This research aimed to assess the actual dose of metal components absorbed by apprentice welders in a learning environment and establish the nature and level of exposure to welding fumes and their metallic components. The study found higher levels of manganese, iron, and nickel in urine and manganese in hair during the Shielded Metal Arc Welding (SMAW) module, while there was no significant difference for the other elements.

Summary: This study investigated the associations between metal exposure and dry eye metrics in shipyard welders. The results showed that certain metal concentrations in urinary and toenail samples were significantly higher in the exposed group compared to the control group. After adjusting for confounding factors, urinary cadmium and toenail lead were significantly associated with dry eye metrics.

Summary: In this study, the distribution of iron, manganese, calcium, and magnesium in the lung, spleen, liver, and kidney of mice after inhalation exposure to different welding methods and steel base materials was investigated. The results showed that the concentration of manganese increased significantly in the lungs and spleens of the MMA groups, and also in the spleens of the MMA-MoMn groups. In the TIG groups, the concentration of manganese was only significantly elevated in the lungs and spleens at 24 hours, and in the livers at 96 hours. Histopathology revealed increased siderin content in the spleens of the treated animals and siderin filled macrophages in the lungs. Anomalies in glycogen metabolism were observed in the MMA groups, while similar glycogen retention and increased vacuoles were found in the livers of the TIG groups, especially in the TIG-stainless steel group at 96 hours. These findings suggest that there is a considerable difference in the distribution kinetics of manganese between the MMA and TIG-fume-treated groups, and that welding fumes may have systemic effects and liver-specific adverse effects.

Summary: This study quantitatively evaluated the efficiency and interaction of technical measures for welding fume protection using advanced Metal-Active-Gas (MAG) process variants. The data derived from the study provides useful information for decision makers in selecting efficient protection measures, and emphasizes the impact of environmental background on measurement results.

Summary: The study found that welding processes with low fume emission rates result in higher direct fume exposure for welders, while processes with high emission rates lead to lower exposure. This is believed to be due to the higher energy input of high emitting processes stabilizing the thermic column and eliminating fume particles from the welder's breathing zone. Exposure can be minimized by additionally optimizing workshop ventilation.

Summary: The study aimed to screen serum differential metabolites of welding fume exposure using UPLC-QTOF-MS/MS. The results showed significant changes in serum metabolism, and lysophosphatidylcholine (20:1/0:0) and phosphatidylglycerol (PGF1 alpha/16:0) may serve as potential biological mediators and biomarkers for laborers exposed to welding fume.

Summary: This study assessed the risk of occupational exposure to welding fume and airborne heavy metals in electronic manufacturing workshops in Hangzhou, China. The air samples collected showed that welding fume was the most abundant contaminant, followed by metals such as iron, manganese, zinc, copper, lead, cadmium, and chromium. It was found that the levels of certain contaminants exceeded permissible limits, indicating a need for engineering controls and management strategies to reduce exposure.

Summary: The aim of the study is to reduce welding fume emissions from flux-cored wires using pulse technology. The results showed that short pulses, medium trigger current, and medium pulse frequency had a positive influence on the emission rate. When using the pulse technology, emission reductions of up to 41% were found.

Summary: This study aimed to investigate the effects of heavy metals on human health and the main influencing factors contributing to personal exposure. The results showed that indoor air pollution was the main contributor to personal exposure, and personal exposure levels varied across different time periods, urban-rural areas, and regions.

Summary: This study aimed to examine whether the results of the mask fit test affect the association between the concentration of metals in biological samples and the results of personal exposures. The study found a positive association between blood Mn concentrations and personal exposure results in the group that failed the mask fit test.

Summary: In this study, the reliability of a field portable X-ray fluorescence spectrometer (FP-XRF) for estimating personal exposures to metal constituents in welding fume was investigated. The FP-XRF showed a strong linear correlation with traditional laboratory analysis methods, but overestimated the mass of some metals. However, the accuracy of the FP-XRF could be improved by developing appropriate correction factors.

Summary: The effect of adding nano-sized arc stabilizing materials on fume emissions and solubility characteristics is discussed in this study. Sodium/potassium titanates of micro and nano sizes were used as substitutes for conventional sodium and potassium silicate compounds in SMAW electrode flux. The newly developed electrodes showed significant reductions in soluble fractions of fumes, with a 50% reduction observed with micro-sized potassium titanate compounds and a further 60% reduction when nano-sodium titanate was added. The inclusion of nano-sized sodium titanate also resulted in reduced fume formation rates and breathing zone concentrations compared to conventional sodium silicate coated electrodes.

Summary: This study evaluated the use of a PDMS-based passive sampler as a tool for assessing personal exposure to aerosol and droplet SARS-CoV-2 in high-risk settings. The findings demonstrate that the passive sampler can effectively detect personal exposure to the virus, providing potential for early detection of cases and guidance on infection control protocols.

Summary: The study examined the effects of multiple exposomal factors on pulmonary inflammation and immune parameters in rats. The results showed that high-fat diet had a greater impact on the immune system of SD rats, while welding fume had a more pronounced effect on immune system recovery in BN rats. These findings highlight the combined impact of genetic, lifestyle, and environmental factors on immune responsivity.

Summary: A scenario-based exposure model is proposed to accurately estimate personal exposure levels of heavy metals using scenario concentrations and time-activity patterns. Personal exposure levels and ambient pollution levels differ significantly, and using the scenario-based exposure model can reduce assessment errors. This method assures the feasibility of personal exposure monitoring and health risk assessments in large-scale studies.
