Biyoaerosol Kompozisyonu ve Karbondioksit (CO2 ) Düzeyinin Covid-19 Salgın Sürecinin Başlangıcında Bir Spor Salonunda Araştırılması

Bu çalışma, Covid-19 salgınının ülkemizde resmi olarak ilk vakanın gözlendiği tarihlerde, çalışmaya gönüllü olarak katılan bir spor salonunda 3 farklı günde (10-12 Mart2020) gerçekleştirilmiştir. Çalışma sırasında salondaki kişi sayısı ve çeşitli parametrelerde kaydedilmiştir. Çalışmanın yapıldığı spor salonunda eğitmen gözetiminde bayanlartoplu olarak pilates aktivitesini gerçekleştirmiştir. Bu çalışmada biyoaerosollerin tür vemiktar tayini ile sıcaklık, bağıl nem, atmosferik basınç ve karbon dioksit (CO2) düzeylerispor salonunun içinde ve dış ortam havasında eşzamanlı olarak ölçülmüştür.Spor salonunda en yüksek CO2 seviyeleri aktivite sırasında ve/ya aktivitelerden hemensonra ölçülmüştür. Spor salonunda toplam bakteri ve mantar seviyeleri 102 ila >103CFU/m3 arasında bulunmuştur. İç ortamda havadan kaynaklı bakteri düzeyleri en düşükaktivite öncesinde ve en yüksek aktivite sırasında ve/ya sonrasında gözlenmiştir. Ortamdaki kişi sayısı ile bakteri ve CO2 düzeyleri arasında lineer ilişki bulunmuştur (r2 ~ 0,7).İç ve dış ortamda sıklıkla gözlenen Aspergillus, Penicillium, Cladosporium ve Alternariamantar türlerine ilaveten; deri ve/ya saç mantar enfeksiyonuna neden olan Microsporumve Trichophyton; insan patojeni Nigrospora ile su sızıntısı olan binalarda kullanılan izolasyon köpüğünde büyüyen Stachybotrys türlerine ise spor salonlarının sadece iç ortamhavasında rastlanılmıştır.

Investigation of Bioaerosol Composition and CO2 Levels in a Gym During the Early Phase of Covid-19 Pandemics

This study was carried out on 3 different days (10-12 March 2020) in a gym that voluntarily participated in the study, on the dates when the first case of Covid-19 was officially observed in our country. The number of people in the gym and various parameters were recorded. In the gym where the study was carried out, the women carried out the pilates activity collectively under the supervision of the instructor. In this study, composition of bioaerosols and temperature, relative humidity, atmospheric pressure and carbon dioxide (CO2 ) levels in the air were measured simultaneously inside the gym and the outdoor air. The highest CO2 levels were measured during and/or immediately after the activities in the gym. The total bacteria and mold levels in the gym were between 102 and > 103 CFU/ m3 . In indoor environment, the lowest airborne bacteria levels were observed before the activity and the highest levels were observed during and/or after the activity. A linear relationship was found between the number of people in the gym and the airborne bacteria and CO2 levels (r2 ~ 0,7). In addition to Aspergillus, Penicillium, Cladosporium and Alternaria, which are frequently observed fungi species both indoor and outdoor; Microsporum and Trichophyton, which are known to cause fungal infections of the skin and/or hair; the human pathogen Nigrospora and Stachybotrys species growing in the insulation foam used in buildings with water leakage were found only in the indoor air of the gym. It is concluded here that the environmental conditions and individual health conditions are important in terms of spread of diseases.
