Uçucu Organik Bileşikler (UOB’ler), atmosfer kimyası ve insan sağlığını önemli ölçüde etkiler. UOB’lerin en önemli kaynakları solvent kullanımı, fosil yakıtlar, araç egzozları ve sigaradır. Çalışmada, araç egzozlarından kaynaklanan UOB’lerin kampüs ana giriş kapılarında dış hava ve iç ortamdaki konsantrasyonlarının belirlenmesi ve tespit edilen UOB’lerin solunması ile giriş kapılarında görevli güvenlik personelinde oluşturacağı sağlık etkilerinin değerlendirilmesi amaçlanmıştır. Örnekleme süresi, giriş kapılarında görevli personelin çalışma süreleri dikkate alınarak belirlenmiştir. Örnekleme noktalarındaki ortalama UOB konsantrasyonları Doğu Kapısı’nda, iç ortamda gece 11.9 µg/m3, gündüz 9.6 µg/m3, dış havada gece 6.8 µg/m3 gündüz 8.8 µg/m3 olarak tespit edilmiştir. Batı Kapısı’nda ortalama UOB konsantrasyonları iç ortamda gece 12.3 µg/m3, gündüz 16.4 µg/m3, dış havada gece 6.3 µg/m3, gündüz 9.3 µg/m3 olarak tespit edilmiştir. Yaşam boyu UOB’lere maruz kalmanın yol açtığı kanserojen risk genel olarak kabul edilebilir risk seviyesi olan 1.0×10−6'nın üzerindedir. Hem iç ortam hem de dış havadaki UOB’ler için kronik toksik etki değeri kabul edilebilir düzeydedir (HQ<1).

Volatile Organic Compounds (VOCs) exert a considerable influence on atmospheric chemistry and human health. The principal sources of VOCs are the use of solvents, fossil fuels, vehicle exhausts and smoking. The objective of the study was to ascertain the outdoor and indoor concentrations of VOCs from vehicle exhausts at the main entrance gates of the campus and to evaluate the potential health effects of inhalation of the detected VOCs on the security personnel working at the entrance gates. The temporal framework for data collection was determined by the working hours of personnel stationed at the entrance gates. The mean VOC concentrations at the sampling points were 11.9 µg/m³ at night and 9.6 µg/m³ during the day at the East Gate, and 6.8 µg/m³ at night and 8.8 µg/m³ during the day in the outdoor air. The concentration of VOCs in the outdoor air was found to be 12.3 µg/m³ at night and 16.4 µg/m³ during the day, and 6.3 µg/m³ at night and 9.3 µg/m³ during the day in the outdoor air. The carcinogenic risks associated with lifetime exposure to VOCs are typically above the acceptable risk level of 1.0×10−6. The chronic toxic effect value for both indoor and outdoor air VOCs is acceptable (HQ<1).
