Lipids peroxidation (LP) and antioxidant defence (AD) were compared in the patients facing pneumoconiosis and dust bronchitis. The studied group included 35 patients with suspected pneumoconiosis, 75 patients facing the 1 grade of pneumoconiosis, 43 coniotuberculosis patients and 43 patients with dust bronchitis. Active LP was demonstrated, values and intensities of its stages depended on the origin and severity of disease. AD was characteristically depressed, which necessitates the antioxidant treatment of patients with pneumoconiosis and dust bronchitis.

Regional and seasonal drivers of metals and PAHs concentrations in road dust and their health implications in the Czech Republic.
Heliyon

While car exhaust emissions in the EU are clearly decreasing, the future of non-exhaust emissions looks more pessimistic. The relative importance of the latter is thus expected to increase in terms of air quality and human health. The aim of the study was to assess regional and seasonal differences in the chemical composition of road dust across the Czech Republic and the health impact of its resuspension, with special respect to polycyclic aromatic hydrocarbons and metals.

Introduction: Respiratory ill-health in welders is well documented but without a clear indication of exposures responsible.
Methods: In a Canadian cohort study of welders and electrical workers, we collected self-reports of asthma/wheeze and rhinitis at each 6-monthly contact for up to 5 years. Physician diagnoses of asthma and chronic obstructive pulmonary disease (COPD/bronchitis) were extracted from the Alberta administrative health database (AHDB).

Background: Foundry workers are occupationally exposed to a variety of inhalable chemical substances. Occupational exposure to vapors, gases, dusts, and fumes can lead to adverse health effects on the respiratory system and cause chronic respiratory diseases, such as interstitial lung diseases (ILDs), chronic obstructive lung disease (COPD), chronic bronchitis, and emphysema. Research on respiratory symptoms, diseases, and lung function in foundry workers over the past few decades has been limited.

This article is an abridged version of the updated AWMF mould guideline "Medical clinical diagnostics in case of indoor mould exposure - Update 2023", presented in July 2023 by the German Society of Hygiene, Environmental Medicine and Preventive Medicine (Gesellschaft für Hygiene, Umweltmedizin und Präventivmedizin, GHUP), in collaboration with German and Austrian scientific medical societies, and experts. Indoor mould growth is a potential health risk, even if a quantitative and/or causal relationship between the occurrence of individual mould species and health problems has yet to be established. There is no evidence for a causal relationship between moisture/mould damage and human diseases, mainly because of the ubiquitous presence of fungi and hitherto inadequate diagnostic methods.
