Abstract:
As chronic exposure to welding fumes causes pulmonary diseases, such as pneumoconiosis, public concern has increased regarding continued exposure to these hazardous gases in the workplace. In a previous study, the inflammatory response to welding fume exposure was analysed in rat lungs in the case of recurrent exposure and recovery periods. Thus using lung samples, well-annotated by histological observation and biochemical analysis, this study examines the gene expression profiles to identify phenotype-anchored genes corresponding to lung inflammation and the repair phenomenon after recurrent welding fume exposure. Seven genes ( Mmp12, Cd5l, LOC50101, LOC69183, Spp1, and Slc26a4) were found to be significantly up-regulated according to the severity of the lung injury. In addition, the transcription and translation of Trem2, which was up-regulated in response to the repair process, were validated using a real-time polymerase chain reaction, Western blotting, and immunohistochemistry. The differentially expressed genes in the exposure and recovery groups were also classified using k-means and hierarchical clustering, plus their toxicological function and canonical pathways were further analysed using Ingenuity Pathways Analysis Software. As a result, this comprehensive and integrative analysis of the transcriptional changes that occur during repeated exposure provides important information on the inflammation and repair processes after welding-fume-induced lung injury.

Abstract:
Abstract To investigate the risk of lung cancer after exposure to welding fumes, hexavalent chromium (Cr(VI)), and nickel, we analyzed 3,418 lung cancer cases and 3,488 controls among men from 2 German case-control studies (1988–1996). We developed a welding-process exposure matrix from measurements of these agents, and this was linked with welding histories from a job-specific questionnaire to calculate cumulative exposure variables. Logistic regression models were fitted to estimate odds ratios with confidence intervals conditional on study, and they adjusted for age, smoking, and working in other at-risk occupations. Additionally, we mutually adjusted for the other exposure variables under study. Overall, 800 cases and 645 controls ever worked as regular or occasional welders. Odds ratios for lung cancer with high exposure were 1.55 (95% confidence interval (CI): 1.17, 2.05; median, 1.8 mg/m3 × years) for welding fumes, 1.85 (95% CI: 1.35, 2.54; median, 1.4 μg/m3 × years) for Cr(VI), and 1.60 (95% CI: 1.21, 2.12; median, 9 μg/m3 × years) for nickel. Risk estimates increased with increasing cumulative exposure to welding fumes and with increasing exposure duration for Cr(VI) and nickel. Our results showed that welding fumes, Cr(VI), and nickel might contribute independently to the excess lung cancer risk associated with welding. However, quantitative exposure assessment remains challenging.

Abstract:
(1) Background: Welding fumes (WFs) are composed of fine and ultrafine particles, which may reach the distal airways and represent a risk factor for respiratory diseases. (2) Methods: In vitro and in vivo studies to understand WFs pathogenesis were selected. Epidemiological studies, original articles, review, and meta-analysis to examine solely respiratory disease in welders were included. A systematic literature search, using PubMed, National Institute for Occupational Safety and Health Technical Information Center (NIOSHTIC), and Web of Science databases, was performed. (3) Results: Dose, time of exposure, and composition of WFs affect lung injury. Inflammation, lung defense suppression, oxidative stress, DNA damage, and genotoxic effects were observed after exposure both to mild and stainless steel WFs. (4) Conclusions: The detection of lung diseases associated with specific occupational exposure is crucial as complete avoidance or reduction of the exposure is difficult to achieve. Further studies in the area of particle research may aid the understanding of mechanisms involved in welding-related lung disease and to expand knowledge in welding-related cardiovascular diseases.

Abstract:
BackgroundAn estimated 110 million workers are exposed to welding fumes worldwide. Welding fumes are classified by the International Agency for Research on Cancer as carcinogenic to humans (group 1), based on sufficient evidence of lung cancer from epidemiological studies.ObjectiveTo conduct a meta-analysis of case-control and cohort studies on welding or exposure to welding fumes and risk of lung cancer, accounting for confounding by exposure to asbestos and tobacco smoking.MethodsThe literature was searched comprehensively in PubMed, reference lists of relevant publications and additional databases. Overlapping populations were removed. Meta-relative risks (mRRs) were calculated using random effects models. Publication bias was assessed using funnel plot, Eggers’s test and Begg’s test.ResultsForty-five studies met the inclusion criteria (20 case-control, 25 cohort/nested case-control), which reduced to 37 when overlapping study populations were removed. For ‘ever’ compared with ‘never’ being a welder or exposed to welding fumes, mRRs and 95% CIs were 1.29 (1.20 to 1.39; I2=26.4%; 22 studies) for cohort studies, 1.87 (1.53 to 2.29; I2=44.1%; 15 studies) for case-control studies and 1.17 (1.04 to 1.38; I2=41.2%) for 8 case-control studies that adjusted for smoking and asbestos exposure. The mRRs were 1.32 (95% CI 1.20 to 1.45; I2=6.3%; 15 studies) among ‘shipyard welders’, 1.44 (95% CI 1.07 to 1.95; I2=35.8%; 3 studies) for ‘mild steel welders’ and 1.38 (95% CI 0.89 to 2.13; I2=68.1%; 5 studies) among ‘stainless steel welders’. Increased risks persisted regardless of time period, geographic location, study design, occupational setting, exposure assessment method and histological subtype.ConclusionsThese results support the conclusion that exposure to welding fumes increases the risk of lung cancer, regardless of the type of steel welded, the welding method (arc vs gas welding) and independent of exposure to asbestos or tobacco smoking.

Abstract:
Exposure assessment quality is a fundamental consideration in the design and evaluation of observational studies. High quality exposure assessment is particularly relevant for outcomes with long latency, such as cancer, where detailed information on past exposures are often missing and must therefore be estimated.For the IARC Monograph on welding, the exposure group provided an overview of assessment methods used in the key epidemiological studies. Strengths and weaknesses of each study were assessed, along with their potential effects on interpretation of risk estimates.For the association between lung cancer and welding fume exposure, 9 cohort and 10 case-control studies were reviewed. For ocular melanoma and ultraviolet radiation (UVR) from welding, 7 case-control studies were reviewed. Quality criteria were: full occupational histories, and standardized, blinded and quantitative exposure assessment. Additional criteria for lung cancer: specifically assessing welding fumes and using information on welding tasks. For ocular melanoma: assessing artificial and solar radiation separately, taking into account eye burns, eye protection and welding type.Exposure assessment of welding fumes by applying a ‘welding-exposure matrix’ (n=2) or welding-specific questionnaires (n=3) were considered highest quality, followed by case-by-case expert assessment (n=5) or general job-exposure matrices (JEMs, n=4). Job title alone was considered less informative (n=5). For exposure to UVR, JEMs were most informative (n=2), followed by self-reported eye burns and self-reported exposure from specific welding types (n=2), although caution is advised regarding recall bias. Assessing welding fume exposure or ever exposure to welding arcs as proxy for UVR was considered less informative. For both exposures, ever versus never welder, or assessments based on data collected from proxies, were considered least informative.The overall evaluation was that there is sufficient evidence in humans for the carcinogenicity of welding fumes and ultraviolet radiation from welding.

Abstract:
BACKGROUND: Exposure to welding fume in the workplace was associated with lung function disorders and occupational asthma. In this study, we determined lung function parameters in men workers exposed to welding fumes from heavy equipment manufacturer. This study is a preliminary study of biomonitoring program in worker exposed to welding fume as our main study. METHODS: A study with case-control design, random study, was conducted among welder (59 subjects) and non-welder (34 subjects) with more than one year experience in the same job task in a heavy equipment manufacturer. All subjects completed physical examination, informed consent, questionnaire and lung function status. Lung function status was measured by spirometer with vital capacity (VC), forced vital capacity (FCV), forced expiratory volume in one second (FEV1) and ratio of FEV1/FVC as test parameters. Linear regression model was developed to identify the risk factor of lung function parameter status using age, working period and smoking status as variables. RESULTS: This study showed that there were significant lower VC, FVC and FEV1 in welder than non-welder, but not difference in ratio of FEV1/FVC. However, there was no significant difference among welder from foundry and fabrication plan. By multivariate analysis, working period was found as a risk factor for lower parameters in lung function among welder. CONCLUSION: Lung function parameters status were significantly lower in welder than non-welder, and working period was the most important indicator for lung function status evaluation among welder. KEYWORDS: vital capacity, VC, forced vital capacity, FCV, forced expiratory volume in one second, FEV1, lung function, ratio of FEV1/FVC, working period

Abstract:
Welders and caulker/burners are usually exposed to heavy clouds of fumes. These fumes contain some gases and particulates which are potentially harmful. There have been several surveys of the health of welders since 1936. These studies demonstrated an association between exposure to fumes and respiratory symptoms. However, no long term effect of fumes on respiratory function has been established. The gases and particulates in the fumes from welding and caulking/burning are very small in size and on this account are capable of reaching the small airways in the periphery of the lung. If welding fumes are harmful to the lung small airway dysfunction should be present in the younger workers. In view of this, in the present study relatively young men were examined and tests specific to small airway function were used. The subjects for this study were male Caucasian workers aged 18 - 47 years, mean age 31.5 years. The target sample comprised 181 welders and 151 caulker/burners and the control sample comprised 181 other tradesmen. The two samples were selected from the same yard. Anthropometry, respiratory symptom and occupational questionnaires, cough frequency questions, forced spirometry, single breath nitrogen test, transfer factor, and an exercise test were performed. The results were submitted to multiple regression analysis. The target workers were compared with the control subjects. Comparisons were also made within the groups of welders and caulker/burners separately. A subsample of the whole selected subjects (age 20 - 25 years) was examined separately to investigate the early effects of fumes on the lung of exposed young workers. In the whole population, compared with the controls, the welders and caulker/burners were found to have significantly higher prevalence of wheeze symptom, and fume exposure interacted with age to increase breathlessness on exertion in the older subjects. In the very young workers (age 20- 25 years) chronic cough and phlegm (chronic bronchitis, MRC) was significantly higher among the target workers compared with the controls. In the group of welders smoking interacted with fumes to increase wheeze in the workers who smoked while increased fume exposure in the older subjects was associated with increased breathlessness on exertion. In the whole population the mean values of closing volume (CV%) and closing capacity (CC%) were significantly higher in the target workers compared with the controls. This effect was independent of age and smoking which were also important. In the subsample of the very young workers similar effects were found, and in addition the mean value of the residual volume (RV%) in the target group was significantly higher than that in the control group. In the whole population fume exposure enhanced the deterioration with age in forced expiratory volume (FEV1) and forced vital capacity (FVC) significantly more in the target workers than in the control subjects. These indices were not affected by exposure in the very young workers. Amongst the group of welders, increased levels of exposure to fumes (duration and intensity) enhanced the deterioration with age in CV%, CC%, breathlessness on exertion and Tlco. High exposure was also associated with decreased Kco in the workers who smoked. Amongst the caulker/burners, increased levels of exposure to fumes enhanced the deterioration with age in CV%, CC%, slope of phase III (SLIII), nitrogen difference index (N2 Diff) and RV%. The findings of the present study are evidence that high levels of fumes from welding and burning or other factors related to these trades, cause long term impairment of lung function of shipyard welders and caulker/burners.

Background Taiwan is an island surrounded by sea and therefore the development of shipbuilding industry is well deployed. The work of many shipyard workers involves welding, cutting and grinding. Welders exposed to the high concentration of hazardous substances as metal fume or dust, and the hazardous substances can have a significant impact on their health. The decreasing of lung function will increase the risk of death is connecting with the diseases as cardiovascular disease and chronic obstructive pulmonary disease. As a result, it is necessary to know the relations between the exposure to metal pollutants and the lung function. Objectives The purpose of this study was to investigate the association between the biomarkers of exposure [urinary metals and urinary (1-hydroxypyrene, 1-OHP)] and respiratory health effects FVC (Forced vital capacity), FEV1 (Forced expiratory volume in one second), FEV1/FVC, MMF (Maximal mid-expiratory flow), FEF25%-75% (Forced expiratory flow rate 25%-75%), PEF (Peak expiratory flow) and FENO (Fractional exhaled nitric oxide) by using a longitudinal design. Methods The subjects of this study were the recruited from one of the shipyards in northern Taiwan. In four consecutive years, started in September in 2014, personal air sampling, questionnaire and health examination were administered to collect data. Data collection strategy included subjects were requested to wear a PM2.5 personal sampler on Monday morning for their 8-hour personal sampling. And for the next day (Tuesday) morning, health examination including urine collection and fasting blood samples were collected. A questionnaire was administered to collect personal information, life style and working habits. Biomarkers of exposure included urinary metals and urinary 1-hydroxypyrene (1-OHP). Respiratory health effects included FVC (Forced vital capacity), FEV1 (Forced expiratory volume in one second), FEV1/FVC, MMF (Maximal mid-expiratory flow), FEF25%-75% (Forced expiratory flow rate 25%-75%), PEF (Peak expiratory flow) and FENO (Fractional exhaled nitric oxide). Result Generalized Estimation Equation (GEE) analyses adjusted variables included age, weight, smoking habit, secondhand smoke, year of data collection, urinary creatinine (μg/g Creatinine) and PM2.5 levels. Results showed that as urinary Manganese increased, FEV1%(β=-0.028; p=0.033), PEF(β=-0.041; p=0.039) and PEF%(β=-0.042; p=0.029) decreased, Cobalt increased, FEV1(β=-0.026; p=0.041), FEV1/FVC(β=-0.012; p<0.001), FEV1/FVC%(β=-0.008; p=0.008) and MMF(β=-0.035; p=0.020) decreased, Cadmium increased, FEV1(β=-0.028; p=0.039) decreased, Copper increased, FEV1/FVC(β=-0.059; p=0.004), FEV1/FVC%(β=-0.047; p=0.031) and MMF(β=-0.200; p=0.030) decreased, Iron increased, FVC(β=-0.026; p=0.043) and FVC%(β=-0.031; p=0.005) decreased, but Nickel in urine increased, FEV1/FVC(β=0.005; p=0.028) and FEV1/FVC%(β=0.007; p=0.006) increased. And with the Cobalt (β=0.080; p=0.003) and Nickel (β=0.053; p=0.019) in urine increased, the FENO increased, but with the PM2.5 (β=-0.038; p=0.043) and 1-OHP (β=-0.144; p= 0.015) in urine increased, the FENO decreased. Conclusion The increasing of biomarkers of exposure of urinary Manganese, Cobalt, Cadmium, Copper, and Iron are associated with decreased lung function. But urinary Nickel is associated with increased lung function. Urinary Cobalt and Nickel are associated with increased FENO. PM2.5 and urinary 1-OHP are associated with increased FENO.

Abstract:
Objectif : Examiner la relation entre une exposition professionnelle aux fumées de soudage au gaz et à l’arc et le risque de développer un cancer du poumon, chez des travailleurs provenant de différents milieux de travail et exposés à de nombreuses substances de différentes concentrations. Méthodes : Nous avons mené deux études cas-témoins basés sur la population montréalaise (1979-86 et 1996-2001), incluant respectivement 857 et 736 cas, ainsi que des témoins appariés selon la fréquence des cas, le sexe et le lieu de résidence. Un historique détaillé des emplois occupés fut obtenu par entrevue et évalué par une équipe d’experts afin d’estimer l’intensité, la durée ainsi que l’exposition cumulative à un grand nombre de substances. Les fumées de soudage au gaz et à l’arc sont parmi les substances évaluées et nous avons pu calculer un rapport de cote (RC) et son intervalle de confiance de 95% (IC 95%) pour le risque de cancer du poumon en utilisant la régression logistique et en ajustant pour l’historique de tabagisme et plusieurs autres covariables pertinentes. Des analyses subséquentes ont permis d’explorer d’autres voies, comme la modification des effets observés par le tabagisme. Résultats : Les résultats obtenus à partir des deux études étant assez similaires, nous avons donc pu les combiner pour former une seule étude. Aucune association statistiquement significative n’a été trouvée entre le cancer du poumon et les fumées de soudage au gaz (RC=1,13; IC 95%=0,90-1,42) et les fumées de soudage à l’arc (RC=1,01; IC 95%=0,80-1,26). Par contre, dans le sous-groupe des non-fumeurs et fumeurs très légers, nous avons trouvé un risque accru de cancer du poumon en relation avec les fumées de soudage au gaz (RC=2,78; IC 95%=1,66-4,65) et à l’arc (RC=2,20; IC 95%=1,32-3,70). En se concentrant sur ce sous-groupe, nous avons trouvé un risque encore plus élevé de développer un cancer du poumon pour ceux exposé à des doses plus substantielles, pour le soudage au gaz (RC=4,63; IC 95%=2,14-10,03) et à l’arc (RC=3,45; IC 95%=1,59-7,48). Discussion : Globalement, aucun excès de risque causé par une exposition aux fumées de soudage n’a été détecté, mais un excès a été trouvé chez les non-fumeurs et fumeurs légers uniquement et ce, pour les deux types de fumées de soudage. L’effet des fumées de soudage peut être voilé chez les fumeurs, ou bien les non-fumeurs pourraient être plus vulnérables.
Objective: To investigate the relationship between occupational exposure to gas and arc welding fumes and the risk of lung cancer among workers exposed to various agents at various concentrations and over a wide range of occupations. Methods: We conducted two population-based case-control studies in Montreal (1979-1986 and 1996-2001), including 857 and 736 cases respectively and frequency-matched controls. Detailed job histories were obtained by interview and evaluated by an expert team of chemist-hygienists to estimate intensity, duration and cumulative exposure to multiple substances for each job. Gas and arc welding fumes were among the agents evaluated, and we estimated odds ratios (ORs) and 95% confidence intervals (CIs) for lung cancer using logistic regression, adjusting for smoking history and other relevant covariates. Subsequent analyses allowed us to explore other avenues, such as effect-measure modification by smoking. Results: The results from both studies were similar, so a pooled analysis was conducted. No significant association was found between lung cancer and gas welding fumes (OR=1,13; 95% CI=0,90-1,42) or arc welding fumes (OR=1,01; 95% CI=0,80-1,26). However, when restricting attention to light and non-smokers, we found an increased risk of lung cancer in relation to gas welding fumes (OR=2,78; 95% CI=1,66-4,65) and arc welding fumes (OR=2,20; 95% CI=1,32-3,70). When we further narrowed attention to workers with the highest cumulative exposures, we found even higher risk of lung cancer for gas (OR=4,63; 95% CI=2,14-10,03) and arc welding fumes (OR=3,45; 95% CI=1,59-7,48). Discussion: There was no detectable excess risk due to welding fumes among smokers; but among light and non-smokers there were excess risks related to both types of welding fumes. The effect of welding fumes may be masked in smokers or light and non-smokers may be more vulnerable.

Abstract:
Abstract. Occupational exposure to respirable crystalline silica, diesel engine exhaust emissions and welding fumes are widespread risk factors for lung cancer, and account for approximately half of the occupational lung cancer burden. If employers succeed in controlling workplace exposures to these process-generated substances, the fraction of lung cancers attributable to occupational exposures could be reduced dramatically.

Abstract:
The construction duration of a nuclear power plant has been considered as a important factor to occupy the competitive edge. For the optimization process of APR1400 which is nuclear reactor newly developed in Korea, it has been suggested that the modularization of reactor vessel internals (RVI) was one of useful means to reduce the construction duration. In general, RVI consists of three components such as core support barrel (CSB), lower support structure/core shroud (LSS/CS) and upper guide structure (UGS). It is complicated and tedious to assemble the RVI by the conventional method which requires about 8∼10 months. In order to modularize the RVI, the gap between the CSB snubber lug and the reactor vessel (RV) stabilization lug must be measured by a remote measurement method. By using a remote measurement method, the welding of CSB and LSS/CS can be performed in advance of the reactor installation process to reduce the construction duration of a nuclear power plant. Compared with the conventional method, the duration of about 2 months required in the welding of CSB and LSS/CS is finally reduced. In this study, first of all we developed the remote measuring system that included the digital probes to measure the 72 points of gap at once. The system device consists of digital probe section, pneumatic supply and control section, electric power section, remote control computer and program. The selected digital probe of linear variable differential transformer (LVDT) type and the calibration device for the zero-point adjustment jig and the other devices have sufficient reliability and accuracy. And the digital probe connection jig has sufficient consistency. The network and system for remote measurement were very stable and no disturbance at electromagnetic interference environment. And we carried out the proof test of our remote measuring system to evaluate the application on the real plant conditions using the RV and RVI mock-up. The results of remote measurement were compared with existing manual measuring method and the reliability of the system was verified. Finally, we confirmed that our remote measuring system had the efficient reliability could be applied to measure the gap of RVI.
