This study was conducted to determine fungal spores in the indoor air of the houses in the city of Afyon, Western-Anatolia, Turkey. We investigated the seasonal properties of mould spores in 10 houses of Afyon over a period of one year. Viable moulds were recovered from all 10 houses. Twenty seven different moulds were isolated and identified from the indoor air of the houses. The most common genus was Cladosporium spp. (31.9%), followed by Aspergillus spp. (18.6%), Penicillium spp. (15.5%), Altemaria spp. (13.0%) and other species (21.0%). The mould concentration was higher in the kitchens than in other parts of the houses such as the living rooms and bedrooms (p < 0.05). The fungal flora of the air in the Afyon city region has a seasonal variation. All fungal species had their highest prevalence in summer and their lowest in winter, but only Aspergillus spp. had a significant seasonal variation (p = 0.012). Viable moulds are common in the houses of Afyon. Reducing these indoor fungi is necessary to improve the health of individuals with fungal-induced diseases like asthma.

Radon (Rn) and thoron (Rn) were reported as the highest contributors to natural radiation received by humans. Furthermore, radon has been stated as the second-highest cause of lung cancer. The concentrations of U and Th (the parent nuclide of radon and thoron, respectively) in nature vary with geological conditions and can be enhanced by human activities.

This study examines the concentration, distribution, and characteristics of suspended microplastics (MPs) across various indoor environments in Malaysia, including offices, classrooms, landed homes, and apartments. Over a six-week period, MPs were collected using a vacuum pump and analyzed through gravimetric analysis, stereomicroscopy, and Raman spectroscopy. The results revealed significant variability in MPs concentrations among different locations, with fibers identified as the predominant morphological type.

TCIPP (tris(1,3-dichloro-2-propyl) phosphate) and TCEP (tris(2-chloroethyl) phosphate) are organophosphate ester flame retardants found in various consumer products, posing significant health and environmental risks through inhalation, ingestion, and dermal exposure. Research reveals these compounds cause oxidative stress, inflammation, endocrine disruption, genotoxicity, neurotoxicity, and potentially hepatotoxicity, nephrotoxicity, cardiotoxicity, developmental, reproductive, and immunotoxicity. This review summarizes the current knowledge on the toxicological mechanisms of TCIPP and TCEP and presents the latest data on their toxicological effects obtained in vitro and in vivo, using omic systems, and on the basis of computational modelling.

Objective: assessment of probable exposure levels from radon and NORM in workplaces within the context of justi fying radiation protection plans in an existing exposure situation.
Materials And Methods: Materials regarding the assessment of naturally occurring radioactive material (NORM) con tent in tailing from mining and processing industries in Ukraine and assessments of contamination levels of industri al sites of oil and gas enterprises were used for estimating the probable range of effective doses (ED) of workers fromNORM at industrial enterprises. These materials were obtained as a result of research conducted by specialists from theRadiation Protection Laboratory of the State Institution «O.
