Abstract (2. Language): 
In this study, the effects of four food preservatives (sodium nitrate, sodium nitrite, and potassium nitrate and potassium nitrite) on the longevity of Drosophila melanogaster were investigated. In the experiments mwh and flr strains of Drosophila melanogaster were used. Third-instars larvae trans-heterozygous were treated of the test compounds at a concentration of 75 mM. Life span data of Drosophila melanogaster (mwh x flr) were evaluated and the lowest mean life span was found to be groups of sodium nitrite. Chemicals used were ranked as potassium nitrite, sodium nitrate, potassium nitrate and control group according to effects of life span. In addition, experimental result show that all of the groups female survived longer than male. The treatment groups which contain nitrite of mean life span was determined shorter than the treatment groups which contain nitrate.

Abstract (Original Language): 
Bu çalışmada, dört gıda katkı maddesinin (sodyum nitrit, sodyum nitrat, potasyum nitrit ve potasyum nitrat) Drosophila melanogaster’de (mwhxflr) ömür uzunluğuna etkisi araştırılmıştır. Deneylerde Drosophila melanogaster’in multiple wing hair ve flare ırkları kullanılmıştır. Üçüncü dönem Trans heterozigot larvalara test kimyasalları 75 mM’lık konsantrasyonlarda uygulanmıştır. Drosophila melanogaster’in (mwh x flr) hayat tablosu verileri değerlendirilmiş ve en düşük ortalama ömür uzunluğu sodyum nitrit uygulanan grupta bulunmuştur. Kimyasallar ömür uzunluğuna etkilerine göre şu şekilde sıralanabilirler: Potasyum nitrit, sodyum nitrat, potasyum nitrat ve kontrol grubu. Ayrıca tüm gruplardaki deney sonuçları dişi bireylerin erkek bireylerden daha uzun yaşadıklarını göstermektedir. Nitrit içeren uygulama gruplarındaki ortalama ömür uzunluğunun nitrat içeren gruplara oranla daha kısa olduğu belirlenmiştir.
