98 unresolved questions extracted from the limitations and future-work sections of 517 Occupational exposure and asthma papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • The adverse health effects of wood dust are influenced by its physicochemical characteristics, the species of wood, processing techniques, particle size distribution, material hardness, chemical composition, and the presence of bioaerosols. Existing occupational exposure limits are often exceeded in woodworking industries. There is a need for further improvement in existing solutions to reduce occupational exposure to wood dust.

  • Reactions to animal biological fluids are poorly described in veterinary occupational health. There is a lack of studies on the clinical features and risk determinants of reactions to mammalian amniotic fluid and blood in veterinarians.

    Situation report: reactions to mammalian amniotic fluid and blood among veterinarians · 2026 · DOI

  • is that the distribution of veterinarians working exclusively or partially in large and/or small animal practice, as well as the time elapsed since graduation, were not collected. These factors could potentially influence both the prevalence of reactions and attitudes toward the use of protective equipment. Notably, despite the frequency of these reactions, few respondents had undergone allergy evaluation, and the results of these assessments were not collected. At the end of the questionnaire, participants were invited to contact the study team if they wished to complete diagnostic investigations but no request was received. In France and Belgium, most veterinarians work in private practice, where health insurance may not automatically cover occupational disease. Moreover, applications for formal recognition are often initiated during career transitions. Veterinarians still actively engaged in their practice may be less inclined to seek formal recognition, which could raise concerns about the sustainability of their professional activity.

  • Exposure to micro-sized cement particles. Inadequate ventilation and insufficient use of personal protective equipment. Limited awareness regarding occupational health protocols.

    Assessment of Occupational Health Hazards and Pulmonary Function Impairment among Cement-Exposed Construction Workers · 2026 · DOI

  • The occupational health hazards faced by cement-exposed construction workers are under-researched. There is a need for quantitative data on the prevalence of occupational cutaneous symptoms and respiratory deterioration among these workers.

  • The complexity of modeling seasonal variations in exposure to metal fumes. The need for accurate and reliable data on metal fume concentrations. The challenge of estimating non-carcinogenic and carcinogenic risks using a simulation-based approach.

    Health risk assessment of exposure to metal fumes among welders under various seasonal conditions: a study based on Monte Carlo simulation · 2026 · DOI

  • Limited knowledge on the health risks of exposure to metal fumes among welders under various seasonal conditions. Lack of a comprehensive assessment of the health risks using a robust simulation-based approach.

    Health risk assessment of exposure to metal fumes among welders under various seasonal conditions: a study based on Monte Carlo simulation · 2026 · DOI

  • The study did not include smokers, which may limit the generalizability of the findings. The study only included lifelong non-smokers to minimize confounding from tobacco exposure. Previous studies often lacked comparison groups, included smokers, and did not adequately assess fine particulate matter (PM2.5) or control for confounding exposures such as biomass fuel use.

    Exposure to respirable dust, fine particulates and crystalline silica and comparative respiratory health patterns among non-smoking workers in the ceramic industry · 2026 · DOI

  • Further studies are needed to investigate the long-term effects of occupational exposure to respirable dust, PM2.5, and crystalline silica on respiratory health. Research on the effectiveness of engineering controls and periodic spirometric surveillance in preventing occupational respiratory diseases is needed. Studies examining the relationship between occupational exposure to respirable dust, PM2.5, and crystalline silica and respiratory health in other industries are required.

  • The lack of harmonised principles for incorporating NAM data into regulatory frameworks. The absence of universally accepted criteria for the quality and validity of NAM-derived data. The need for a fundamental shift in how evidence from NAMs is evaluated and used in decision-making.

    The NAMs conundrum in the current regulatory risk assessment: progress without clarity? · 2026 · DOI

  • The complex and multifaceted nature of airborne contaminants in poultry barns underscores the challenges in addressing respiratory health risks among workers. The paper identifies the need for careful nutritional formulation when using dietary manipulation to reduce harmful substances in poultry barns.
