PAH'lar Ve PCB'lerin Atmosferik Konsantrasyonları: Bursa Doğu Atıksu Arıtma Tesisi Örneği

Öz

Bu çalışma Bursa Doğu Atıksu Arıtma Tesisinde PAH ve PCB' lerin atmosferik seviyelerinin belirlenmesi amacıyla PÜK diskli pasif hava örnekleyicisi kullanılarak Eylül ve Aralık 2016 tarihlerinde örnekler alınmıştır. Bu çevresel kirleticilerin zamansal değişimleri ve türleri tespit edilmiştir. Verilen örnek tarihleri bir önceki ay için biriken kirletici konsantrasyonlarını temsil etmektedir. Tesisten alınan örneklerde ∑₁₆ PAH türünün konsantrasyonları Eylül  ve Aralık 2016 için sırasıyla 23,35 ng/m³ ve 256,51 ng/m³ olarak belirlenmiştir.  PAH türlerinde fenantren ve floranten her iki dönemde baskındır. S₆₀PCB konsantrasyonu Eylül ve Aralık 2016 için sırasıyla 0,421 ng/m³ ve 0,0969 ng/m³ olarak ölçülmüştür. PCB' de ise düşük molekül ağırlıklı türler baskındır. Kirletici seviyeleri ve türleri tesisin bulunduğu konum,yakıt kullanımı, mevsimler ve çamur lagünlerine yakınlığa bağlı olarak etkilenir.
