Abstract

In the present study, the genotoxic effect of wastewater including heavy metals was investigated. For this purpose, the induction/reduction of mutation and recombination of surface water sampled before and after the discharge points (station-I,II) of the local fat plant (Erzurum, Turkey) were investigated by wing Somatic Mutation and Recombination Test (SMART) of the Drosophila melanogaster. In this study, thirdinstar larvae, which are trans-heterozygous for the third chromosome recessive markers with multiple wing hairs (mwh) and flare-3 ($flr^3$) were separated into groups and were exposed to two different water samples including high and low metal ion concentrations. These larvae were kept in the culture media until the adult stage. Wing preparates of obtained adult individuals were prepared and examined under a light microscope. Frequencies of mutant clones formed through application of surface water samples taken from station I and station II in different periods and frequencies of the control group were compared by a Conditional Binominal Test. While it was observed that the samples taken from station I did not cause an increase in the total mutant clone frequency whereas the samples obtained from station II did. It was suggested that the metal ion concentration was determined to be higher in station II which might have lead to this result.

Özet

Sunulan çalışmada, ağır metal içeren atık suların genotoksik etkisi araştırıldı. Bu amaçla, Drosophila melanogaster`in kanat Somatik Mutasyon ve Rekombinasyon Testi (SMART) ile yerel yað fabrikasının (Erzurum, Türkiye) atıklarının döküldüğü noktanın öncesinde ve sonrasında (istasyon I-II) yüzey su örneklerinin mutasyon ve rekombinasyonunu arttırıp arttırmadığı araþtırıldı. Bu çalışmada, üçüncü kromozomları üzerinde çoklu kıl (mwh) ve topaklaşmış kıl ($flr^3$) meydana getiren iki farklı çekinik işaret gen taşıyan trans-heterozigot üçüncü evre larvalar gruplara ayrılarak, yüksek ve düşük metal konsantrasyonlarını içeren iki farklı su örneği uygulandı. Bu larvalar ergin oluncaya kadar bu kültür ortamlarında tutuldu. Elde edilen ergin bireylerin kanat preparatları hazırlanarak ışık mikroskobunda incelendi. Binominal şartlı Test kullanılarak istasyon I ve istasyon II'den farklı dönemlerde alınan yüzey su örneklerinin uygulanması ile oluşan mutant klonların frekansları, kontrol grubu frekansları ile karşılaştırıldı. istasyon I'den alınan örneklerin toplam mutant klon frekansında artışa neden olmadığı gözlenirken istasyon II'den alınan örneklerin ise mutant klon frekansını arttırdığı bulunmuştur. İstasyon II'de daha yüksek olduğu belirlenen metal iyon konsantrasyonunun bu sonuca neden olabileceği öne sürülmüştür.
