DETERMINATION OF MERCURY, LEAD, CADMIUM, COPPER, IRON AND MANGANESE IN SHEEP, COW AND CHICKEN LIVER SAMPLES IN TURKEY

Karaciğer, metabolik süreçlerde yer alan en önemli organ olup, vücudun herhangi bir rahatsızlığının en belirgin tanıklarından biri olarak değerlendirilir. Bu çalışmanın amacı, koyun, dana ve tavuk karaciğer örneklerindeki cıva, kurşun, kadmiyum, bakır, demir ve mangan derişimlerini tayin etmektir. Metot validasyonu, standart referans materyalin (BCR CRM 422 Morina balığı kası) analizi ile gerçekleştirilmiştir. İncelenen hayvan karaciğerlerinden koyun ve danada bakır seviyesi 640-675 mg/kg aralığında bulunmuştur. Karaciğer örneklerinde diğer metallerin derişimleri sırasıyla cıva için 17.2-402 µg/kg, demir için 129-411 mg/kg ve mangan için 30.2-141 mg/kg aralığında bulunmuştur. Cıva ve mangan ise tavuk karaciğer örneklerinde en yüksek miktarda bulunmuştur. İncelenen bazı karaciğer örneklerinde, izin verilen maksimum sınırların aşıldığı belirlendiğinden etkili ekolojik önlemlerin alınması toplum ve çevre üzerinde yararlı bir etkiye sahip olacaktır

TÜRKİYE'DEKİ KOYUN, DANA VE TAVUK KARACİĞER ÖRNEKLERİNDE CIVA, KURŞUN, KADMİYUM, BAKIR, DEMİR VE MANGAN TAYİNİ

Liver is the most important organ involved in metabolic processes and is considered to be one of themost eloquent witnesses of any disturbance in the body. The aim of the present study is to determinemercury, lead, cadmium, copper, iron and manganese concentrations in sheep, cow and chicken liversamples. The validation of the method was confirmed by analysis of standard reference material (BCRCRM 422 Cod Muscle). Levels of copper in the sheep and cow 640 and 675 mg/kg, respectively andwere the highest in the animal livers examined. The concentration of other metals in liver sampleswere found in the range of 17.2-402 µg/kg for mercury, 129-411 mg/kg for iron and 30.2-141 mg/kg formanganese. Chicken liver samples were found to contain the highest amount of the mercury andmanganese analyzed. With regard to the fact that in some samples maximum allowable limits for liversamples were exceeded, effective ecological measures should be taken that would have a beneficialeffect on the landscape and environment
