While the annual incidence of ill-health-related job loss in the French workforce is estimated at 7.8 per 1,000 workers, the specific burden among cleaners remains unknown. This study aimed to quantify the incidence of medical unfitness among cleaners in France and to identify the principal diseases and demographic factors associated with job loss. A 4-year follow-up study (2016-2019) was conducted within the occupational health service of Montpellier, France. All employees deemed medically fit at baseline were included. Demographic and occupational data were extracted from electronic medical records. All decisions of medical unfitness for work issued by occupational physicians according to legal procedures were collected along with their ICD-10 diagnostic causes. Incidence rates and disease profiles were compared between cleaners and other workers. Among 118,033 workers, 13,089 were cleaners. The annual incidence of ill-health-related job loss was 2.3 times higher among cleaners (16.7 ‰ or <i>permille</i>); 95% Confidence Interval (CI) [15.6;17.8]) than in the overall population (7.3‰; 95% CI [7.1;7.6]. Musculoskeletal disorders and mental disorders were the most frequently reported causes of unfitness among cleaners (both 57.7%). Less frequent conditions, including schizophrenia (RR = 8.11) and cardiovascular diseases (RR = 6.55), were markedly over-represented in this group. Cleaners experience a substantially elevated risk of ill-health-related job loss compared with other workers, largely driven by musculoskeletal and mental disorders. Over-representation of severe psychiatric and cardiovascular diseases highlights the need for targeted preventive strategies in this socio-economically vulnerable group.</p>","PeriodicalId":16599,"journal":{"name":"Journal of Occupational and Environmental Hygiene","volume":" ","pages":"1-6"},"PeriodicalIF":1.4,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149017276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Portable diffusion-charging instruments may facilitate personal exposure monitoring; however, their performance under occupational 3D printing conditions remains insufficiently characterized. This study evaluated the Partector 2 Pro (Naneos GmbH, Windisch, Switzerland) against reference instruments during controlled printing of four commonly used thermoplastic filaments: polylactic acid (PLA), polyethylene terephthalate glycol (PETG), thermoplastic polyurethane (TPU/S-Flex), and nylon. Experiments were conducted in a wind tunnel to ensure stable emission conditions. Total particle number concentrations measured by the Partector 2 Pro were compared with those obtained from a scanning mobility particle sizer (SMPS) and a condensation particle counter (CPC), while particle size percentiles (D10 to D95) from the Partector 2 Pro were compared with those from the SMPS. For comparisons of concentrations, strong agreement was observed across all materials, with regression slopes ranging from 0.88 to 1.05 and Pearson's correlation coefficients higher than 0.96. Mean deviations ranged from -9.6% to +6.2%, remaining well within the manufacturer's stated ±30% accuracy specification. For comparisons of particle size metrics, the Partector 2 Pro systematically underestimated mobility diameters (slopes 0.82 to 0.90; <i>r</i> = 0.98 to 0.99). The magnitude of deviations was size-dependent, ranging from -27.0% to +7.5% for the smallest particles (D10), -28.3% to -7.3% for intermediate particles (D25 through D75), and -17.6% to -7.9% for the largest particles (D95).

Chronic exposure to VCM may lead to serious health problems. Thiodiglycolic acid (TDGA) acts as a biomarker for exposure to VCM; hence, its quantitative estimation in urine provides precise information about exposure level. In this study, the authors propose a newly developed colorimetric assay based on metal-organic framework (MOFs), specifically MIL-100(Fe), acting as a nanozyme. In particular, it shows strong peroxidase-like activity; as such, it generates blue color in response to hydrogen peroxide (H₂O₂) and 3,3',5,5'-Tetramethylbenzidine (TMB). The optimum reaction conditions were determined via response surface methodology (RSM) to maximize the assay's sensitivity and performance. Under optimal conditions, the method achieved a limit of detection (LOD) of 2.48 ppm and a linear range of 1 to 200 ppm. The assay demonstrated high accuracy and precision in spiked urine samples, with recoveries ranging from 93.74% to 96.81% relative to theoretical values. The proposed test provides ease of performance, scalability, and cost efficiency as well as acceptable specificity and sensitivity; hence, it would be an ideal method for estimating exposure levels to VCM in human workers. The developed colorimetric assay, in contrast to present gold standard techniques such as GC-MS, is transportable, and the analysis can be done either by an inexpensive UV-Vis spectrophotometer or a smartphone. The whole process can be accomplished in less than 15 min, which makes it amenable to site-specific biologic monitoring in the petrochemical industry. This can be especially relevant in developing nations. The proposed method bridges an important gap for biological monitoring in occupational health surveillance where a need for immediate, cost-effective, and transportable methods for testing TDGA exists.</p>","PeriodicalId":16599,"journal":{"name":"Journal of Occupational and Environmental Hygiene","volume":" ","pages":"1-10"},"PeriodicalIF":1.4,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148969350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This assessment uses internationally accepted eye and skin hazard analysis methods. To quantify the infrared, ultraviolet, and blue-light irradiances at a distance of at least 1 m, compare with Exposure Limit Values (ELV), and calculate the maximum transmittances to reduce the irradiance to below ELVs. Spectral irradiance data of 196 welding arcs were obtained from the Institut National de Recherche et de Sécurité (INRS, National Research and Safety Institute for the Prevention of Occupational Accidents and Diseases, France) CatRayon 5 UV-VIS-IR and the Institut für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung (IFA, Institute for Occupational Safety and Health of the German Social Accident Insurance, Germany) UV-VIS databases. The irradiances (IR, UV, and blue-light) at 1 m from the arc were calculated according to the International Commission on Non-Ionizing Radiation Protection (ICNRP) and European Union Directives and compared with the ELVs to provide the required transmittance. The worst case was used to recommend a maximum transmittance. Few arcs exceeded the IR ELV at 1 m, and beyond 1.3 m, none exceeded the ELV. All arcs exceeded the effective UV ELV, and a maximum effective UV transmittance of 0.002% was required to reduce the effective UV irradiance below the ELV. Eighteen of the arcs did not exceed the blue-light irradiance ELV for small sources. For the remaining 179 arcs, a maximum blue-light transmittance of 3.7% was required to reduce the effective blue-light irradiance below the ELV. Welding curtain standards need not have IR transmittance requirements, but guidance for the use of welding curtains should include that they be located at least 1 m from the arc and that recommendation should accompany the products at the point of sale. A maximum UV transmittance of 0.002%, calculated using the corneal and skin hazard weighting function, is proposed to cover the worst-case arc.
