Karacabey (Bursa) İlçesinin Hidrojeoloji İncelemesi ve İçme Sularının Sağlık Risk Değerlendirmesi

Bu calismada Karacabey (Bursa) ilcesi ve cevresinde yeraltisularinin hidrojeokimyasal ozellikleri incelenmis ve saglik risk degerlendirmesi yapilmistir. Inceleme alaninda yeraltisularinin Ca-HCO 3, Ca-Mg-HCO 3 ve Mg-Ca-HCO 3 ’li sular fasiyesinde oldugu tespit edilmistir. Mg artisi formasyonlar icerisindeki kumtasi ve konglomera seviyeleri ile kaya-su etkilesiminden kaynaklanmaktadir. Inceleme alaninda sularin genel olarak fiziksel ozellikleri ve anyon-katyon icerikleri acisindan icme suyu sinir degerlerini asmadigi tespit edilmistir. Ancak, yeraltisularinin As icerigi 9-79.1 µg/l arasinda degismektedir. As artisi genelde volkanik kayaclarla iliskili olarak jeojenik kokenlidir. Bazi lokasyonlarda NO 3 , Fe ve Mn iceriklerinin de icme suyu standart degerlerinin uzerinde oldugu tespit edilmistir. Bu artislarin jeojenik ve antropojenik kokenli oldugu dusunulmektedir. Calismada icme suyu sinir degerlerini asan As, NO 3 , Fe ve Mn parametreleri icin saglik risk degerlendirmesi yapilmistir. Su kaynaklarinin oral (icme) ve dermal (deri) yolla alim ile gerceklesebilecek tehlike katsayilari (HQ), tehlike endeksi (HI) ve kanser riski degerleri yetiskin ve cocuk bireyler dikkate alinarak hesaplanmistir. Su kaynaklarinin icmesuyu olarak uzun sureli kullaniminda saglik icin olumsuz etki olusabilecegi tespit edilmistir. As elementi acisindan kanser riski olasiligi da bulunmaktadir.
