    A proposal of indoor air pollutant limit values for Turkish schools based on a literature review of emission sources, concentrations, health effects, and limits/guidelines

    Limit Values Working Group (LVWG) was established under Indoor Air Quality Committee of Turkish Climatization Assembly of the Union of Chambers and Commodity Exchanges of Türkiye. LVWG was tasked with reviewing the pertinent literature on indoor emission sources, concentrations in schools, health effects, and existing limit and guideline values to identify the indoor air pollutants that need to be addressed and to be recommended a limit value for Turkish schools. LVWG members took responsibilities based on their individual expertise. The recommendations were concluded in consensus decision-making after in-group discussions. A total of 19 pollutants/pollutant groups (carbon dioxide, carbon monoxide, nitrogen dioxide, ozone, radon, volatile organic compounds, formaldehyde, trihalomethanes, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, brominated flame retardants, organophosphate esters, phthalate esters, particulate matter, bioaerosols (bacteria, fungi, viruses), microbial pollutants and allergens) were reviewed. Limit values were recommended for 11 pollutants/groups based on the current knowledge, i.e. pollutant health effects and indoor air concentrations taking into account the exposure duration, the prevalence of existing limit/guideline values and the health effects on which they are based. © 2025 Turkish National Committee for Air Pollution Research and Control

    Assessment of physicochemical and microbiological water quality and bacterial biofilm formation in the coastal waters of Çanakkale, turkey
    (Corvinus University of Budapest, 2021) Onat, Burcu; Doğru Hacıoğlu, Nurcihan
    This study, it was aimed to determine water quality based on the physicochemical and microbiological parameters, as well as microbial indicators (in addition to antibiotic-heavy metal resistance and biofilm formation) in Çanakkale Coastal waters, Turkey. The results showed that the stations were within acceptable limit values in terms of general sanitation values, however, the isolated bacteria showed high antibiotic and heavy metal resistance and biofilm formation capacity. A total of 68 Gram negative bacterial isolates were collected from the Çanakkale coastline, and were recorded as Aeromonadaceae, Burkholderiaceae, Enterobacteriaceae, Plesiomonodaceae, Pseudomonadaceae, Shewanellaceae and Vibrionaceae. The highest antibiotic resistances were detected against cephalothin, erythromycin, cefoxitin antibiotics from all bacterial isolates. Frequency of resistance of isolated bacteria against heavy metals (Cu2+, Cd2+, Cr3+, Pb2+ and Mn2+) were detected as averages of 67.64%, 60.29%, 86.76%, 79.41% and 92.64%, respectively. Sixty bacterial isolates also exhibited strong biofilm formation. This study demonstrated that the coastal waters of Çanakkale represented a rich source of bacterial diversity and high incidence of antibiotic and heavy metal resistance and biofilm formation among isolated bacteria. It is expected that this study will lead to more comprehensive researches to investigate microbial quality in terms of public health in coastal waters and seafood in the region.
