The objective of this study was to determine whether the COVID-19 pandemic was associated with a change in the rate of toxic inhalation (TI) injuries following occupational exposure to cleaning chemicals. This retrospective study spanned from July 1, 2017, to June 30, 2022, with January 1, 2020, designated as the pandemic start. TI cases were identified among workers' compensation claims filed in Washington State, USA using keyword text search and diagnostic and insurance codes. Qualitative claim data were reviewed to determine the frequency of cases with exposure to aerosolized disinfectants following spray or fog application. Rates of TI claims per full-time equivalent (FTE) workers were compared in the pre- and pandemic periods. Out of the 440 TI claims identified, 30% involved exposure to disinfectants and 13% had a diagnosis of work-related asthma. There was a decline in the overall rate of TI claims in the pre- <i>vs</i>. pandemic period (8.9/100,000 FTE <i>vs</i>. 7.4/100,000 FTE, respectively). However, the proportion of exposures to disinfectants increased during the pandemic period. Four industries, particularly \"Transportation and Warehousing,\" experienced an increase in TI injury rate. Fog or spray application of disinfectants was involved in 20 cases (including 14 in bus transportation) during the pandemic, compared to zero cases in the pre-pandemic period. In Washington State, the COVID-19 pandemic was associated with industry-specific increased TI injury rates due to cleaning chemicals, but not an overall increased rate. A case series emphasizes that aerosolized disinfectants are a toxic inhalation risk for workers. Studies to further characterize this practice and these injuries are warranted. Prevention efforts should utilize the hierarchy of controls as well as address hazard awareness, product over-application, and the need to estimate and uphold a safe re-occupation time after fog or spray application of disinfectants.</p>","PeriodicalId":16599,"journal":{"name":"Journal of Occupational and Environmental Hygiene","volume":" ","pages":"406-416"},"PeriodicalIF":1.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147930407","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}

Muller, Nobel Prize recipient for producing gene mutations, was the de facto leader of the radiation genetics community from the mid-1920s until he died in 1967. Muller had a major impact on US hereditary/cancer risk assessment policies/practices, and the course of the secondary school biological sciences curriculum development in the US and worldwide. Despite these accomplishments, Muller was at the center of provocative controversies. Within this context, this paper reports the discovery of a letter (April 4, 1956) from Muller to Warren Weaver, Chair of the BEAR I Genetics Panel, about a major controversy in which the radiation-induced hereditary damage estimates of Panelist Milisav Demerec were strikingly lower than those of others, especially Muller's. In this recently discovered letter, Muller attempted to reconcile these differences and unexpectedly claimed that Demerec's estimates were correct. However, Muller appears to have inexplicably confused the evaluation by switching his focus away from Demerec's data on radiation-induced mutation rates in bacteria to his old unresolved dispute with Demerec regarding fruit flies. He even suggested that Demerec was correct in that Muller's groundbreaking mutational research had induced mostly major chromosomal aberrations rather than gene mutations. Muller curiously suggested that he had thereby resolved the conflict amongst Demerec, himself, and other BEAR I Genetics Panel members. Yet, as noted, Demerec's data for the BEAR I Genetics Panel mutation risk estimates were based on his (i.e., Demerec's) more current research on bacteria, with Muller completely missing the entire point of the Panel's scientific conflict with the Demerec data. Thus, Muller never addressed the real issue. This transitory detachment from factual reality by Muller is obvious and acute. Finally, if Weaver had shared this letter from Muller with the BEAR I Genetics Panel, it seems possible that many members might have been so troubled by Muller's apparent detachment from reality (on such a consequential disagreement) that they would have questioned why they had allowed Muller to exert so much influence on their report.</p>","PeriodicalId":16599,"journal":{"name":"Journal of Occupational and Environmental Hygiene","volume":" ","pages":"499-507"},"PeriodicalIF":1.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147973278","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}

To address these aims, a database was developed that listed the chemical OELs from the German MAK (Maximale Arbeitsplatz-Konzentration) Commission, U.S. National Institute for Occupational Safety and Health (NIOSH), U.S. Occupational Safety and Health Administration (OSHA), California OSHA, American Conference of Governmental Industrial Hygienists (ACGIH<sup>®</sup>), and the Workplace Environmental Exposure Levels Committee (WEEL; initially derived under the American Industrial Hygiene Association (AIHA<sup>®</sup>), and after 2012 via Toxicology Excellence for Risk Assessment (TERA)). Information on inhalation toxicity, specifically respiratory irritation, was also included. Analyses of the collated data found the following. Most chemicals in the database with at least one OEL had three or four OELs from different organizations; there was variability among the OEL numeric values, but most chemicals differed by a factor of less than 10. The respiratory tract was the site of the critical or co-critical effect (i.e., the one occurring at the lowest concentration) for ∼50% of the chemicals in the database, illustrating the importance of consideration of this target organ in OEL development. Inconsistencies between GESTIS-curated Globally Harmonized System (GHS) Hazard (H) codes and OEL documentation regarding respiratory effects were identified, suggesting that the potential for respiratory effects may not be adequately addressed in assigning H codes.
