Nilüfer Çayı Sedimentinde Polisiklik Aromatik Hidrokarbon (PAH) Seviyelerinin İncelenmesi

Öz

Deniz, göl, nehir gibi su sistemlerindeki sedimentler polisiklik aromatik hidrokarbonlar (PAH’lar) için alıcı ortam vazifesi görürler. Alıcı su ortamlarında sudaki kirlilik kadar  nihai alıcı ortam olan sedimentteki kirliliğin de ortaya konması mevcut durumun tespiti ve ıslah çalışmalarının planlanması açısından büyük önem arz etmektedir. Bu çalışmada, Bursa’nın en önemli su kaynaklarından olan Nilüfer Çayı’nda sedimentteki PAH konsantrasyonlarının bölgesel ve mevsimsel değişiminin belirlenmesi amaçlanmıştır. Bu kapsamda, Nilüfer Çayı’nın sekiz farklı noktasından dört mevsim boyunca 32 adet sediment örneği alınmıştır. Sedimentteki ∑12 PAH konsantrasyonlarının mevsimsel ve bölgesel olarak değişim gösterdiği tespit edilmiş olup konsantrasyonlar 15-9600 ng/g katı madde (KM) aralığında çıkmıştır. En yüksek ∑12 PAH konsantrasyonları kış mevsiminde ölçülürken konsantrasyonlar yazın diğer mevsimlere nazaran düşük seviyelerde çıkmıştır. Kış mevsiminde PAH kirliliğinin en fazla olduğu Panayır deresinde ∑12 PAH konsantrasyonu 9600 ng/g KM olarak tespit edilmiştir. Yaz mevsiminde ise yoğun endüstriyel atıksu deşarjının olduğu bölgelerde dahi konsantrasyonlar 1000 ng/g KM’yi aşmamıştır.
