Comparison of indoor to outdoor concentration ratios of dust for PAHs, PCBs and PBDEs

Abstract

In past 50 years, with migration of human population from rural to urban areas, both industrialization and urbanization bring with air pollutions problems and consequently cause to increase respiratory and other corresponding diseases. Since people, especially those living in urban areas, spend more than 90% of their time indoors, recently indoor air quality has been paid attention as well as ambient air quality. In the current study, the indoor and outdoor dusts of 80 houses in Kocaeli were simultaneously collected in February and March in 2016. The 16 Polyaromatic Hydrocarbons (PAHs), 14 Polybrominated diphenyl ethers (PBDEs) and 15 Polychlorinated biphenyls (PCBs) were detected. Indoor to Outdoor (I/O) ratio for PAHs (ranging from 1.1 to 3.2) were not detected as high as PBDEs (range from 1.9 to 7.2) and PCBs (ranging from 1.8 to 7.9). The I/O ration for PBDEs and PCBs were comparable. Larger than one of I/O ratios in such a city with high loading of industrial and traffic and these ratios reached to 8 for PBDEs and PCBs indicated the importance of indoor air quality. Therefore certain precautions to regulate indoor air quality should be considered.

PAH, PCB ve PBDE'lerin iç/dış ortam toz konsantrasyon oranlarının karşılaştırılması

Öz

Özellikle son 50 yılda insan nüfusunun kırsal kesimlerden şehirlere doğru kayması ile birlikte gerek sanayi gerekse yoğun yaşam mahallerinin neden olduğu hava kirliliği özelikle üst solunum ve buna bağlı diğer hastalıkların artmasına neden olmaktadır. Özellikle büyük şehirlerde yaşayanlar, zamanlarının büyük bir bölümünü iç mekanlarda geçirdikleri için son zamanlarda dış ortam havasının yanı sıra iç hava kalitesi de insan sağlığı için önemli olmaya başlamıştır. Bu çalışmada, 2016 yılı Şubat ve Mart aylarında Kocaeli'deki 80 evin iç ve dış mekan tozları eş zamanlı olarak toplanmıştır. 16 Poliaromatik Hidrokarbon (PAH), 14 Polibromlu difenil eter (PBDE) ve 15 Poliklorlu bifenil (PCB) için toz örnekleri analiz edilmiştir. PAH için ölçülen İç ortam/Dış Ortam (I/O) oranları (1.1-3.2 arasında), PBDE (1.9 ila 7.2 arasında) ve PCB (1.8-7.9 arasında) I/O oranlarına göre düşüktür. PBDE ve PCB I/D oranları birbirine yakın değerler bulunmuştur. Sanayi ve trafik yoğun bir şehirde I/D oranlarının 1’den büyük olması ve PBDE ve PCB için bu değerlerin yaklaşık 8 kata kadar çıkması iç ortam hava kalitesinin önemini göstermektedir. Bu sebeple iç ortam hava kalitesinin düzenlenmesi için bazı önlemler alınmalıdır.
