CLADOPHORA GLOMERATA (CHLOROPHYCE)’DA AĞIR METAL BİRİKİMİNİN ARAŞTIRILMASI

Öz

Bu çalışmada, Kızılırmak Nehri üzerinde belirlenen beş istasyondan toplanan Cladophora glomerata (Chlorophyceae) örneklerinde ağır metal birikiminin düzeylerini araştırdık. Bu amaçla bitkinin fotosentez, solunum, büyüme ve gelişmesinde etkili olan sodyum (Na), magnezyum (Mg), fosfor (P), potasyum (K), kalsiyum (Ca), mangan (Mn), selenyum (Se) ve iyot (I) gibi iz ve makro elementler ile, belirli bir miktarın üzerinde canlılar için toksik sayılan alüminyum (Al), krom (Cr), demir (Fe), nikel (Ni), bakır (Cu), çinko (Zn), kadmiyum (Cd) ve kurşun (Pb) gibi ağır metallerin yoğunlukları, elektron dağılım spektroskopisi (EDS) kullanılarak belirlendi. Sonuçta, üçüncü, dördüncü ve beşinci istasyonlardan toplanan örneklerdeki ağır metal seviyeleri, karşılaştırıldığında daha yüksekti. Bu sonuçlar Cladophora glomerata’nın ağır metal birikiminin araştırılmasında hassas ve kullanışlı bir biyoindikatör olduğunu gösterdi.
