Determination of heavy metal pollution in honey samples collected from Ardahan and counties

Abstract

In this study the concentrations of some element levels in 180 honey samples obtained from honey producers producing beekeeping from all the counties of Ardahan province (Center, Hanak, Çıldır, Göle, Damal) in 2015 were investigated. The levels of Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sr and Zn elements in honey samples were determined by ICP-OES instrument. In the samples pretraement a microwave oven. The mean of element levels and the lowest and highest values were determined in honey collected from city center and counties. Of the samples analyzed for Cd, Co, Cr and Pb values was found below the detection limit. As a result of analysis, the content of element in honey were detected as 124,863 ± 313,44 ppb, 1227,56 ± 892,22 ppb, 67,352 ± 34,636 ppb, 6484,904 ± 2078,892 ppb, 302,551 ± 323,329 ppb, 4,636 ± 3,943 ppb, 3118,69 ± 835,149 ppb and 10,535 ± 14,73 ppb, for Al, Ca, Fe, K, Mg, Mn, Na and Sr respectively. To conclude, the results of this study below the maximum residue limits when compared to some international limits. It was concluded that the samples analyzed would not pose any danger to human health.

Ardahan ve İlçelerinden Toplanan Bal Örneklerinde Ağır Metal Kirliliğinin Belirlenmesi

Öz

Yapılan çalışmada, 2015 yılında Ardahan ilinin tüm ilçelerinden (Merkez, Hanak, Posof, Çıldır, Göle, Damal) arıcılık yapan bal üreticilerinden temin edilen 180 adet bal numunesinde bazı element düzeyleri araştırıldı. Bal numunelerinde Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sr ve Zn elementlerinin düzeyleri ICP-OES cihazı ile belirlendi. İl merkezi ve ilçelerine göre ortalama element düzeyleri ile en alt ve en üst değerler tespit edildi. Analizi yapılan numunelerin Cd, Co, Cr ve Pb değerlerinin tümü tespit limitinin altında bulundu. Yapılan analiz sonucunda balların element içeriği; Al 124,863± 313,44 ppb, Ca 1227,56± 892,22 ppb, Fe 67,352±34,636 ppb, K 6484,904±2078,892 ppb, Mg 302,551±323,329 ppb, Mn 4,636±3,943 ppb, Na 3118,69±835,149 ppb ve Sr 10,535±14,73 ppb olarak tespit edildi. Bu çalışmada elde edilen sonuçların, bazı uluslararası limitlerle karşılaştırıldığında da maksimum kalıntı limitlerinin oldukça altında olduğu tespit edilmiştir. Analizi yapılan örneklerin insan sağlığı açısından herhangi bir tehlike teşkil etmeyeceği sonucuna varılmıştır.
