Abstract

In this study, detection of a possible relationship of some trace element levels of copper (Cu), zinc (Zn), and iron (Fe), toxic heavy metals, cadmium (Cd) and lead (Pb), and antioxidant functions in cattle, which are living near the trunk roads for at least 3 years, was aimed. Totally, 70 cattle, which were in diff erent herds, were used. Fifty-four cattle (3-13 years), which were living near the trunk roads at about 0-500 m were used for the experiment group. Also, 16 cattle (3-12 years), which were living far from trunk roads at about 2-3 km were used for the control groups. Blood samples were collected and Cd, Pb, Cu, Zn, Fe levels, lipid peroxidation product malondialdehyde (MDA) and antioxidative defense system indicators, erythrocyte superoxide dismutase (SOD) activity, catalase (CAT) activity, and plasma ceruloplasmin (CP) level were measured. Cd and Pb levels of the experimental animals were determined to be higher than the control group (P<0.01 and P<0.001, respectively). However, Zn level of the experiment group was found lower than the control animals (P<0.001). MDA increased about three times and CP increased about two times more than the control group (P<0.001). Significantly correlations were observed among Pb, MDA and CP levels. Also, important correlations were found between Fe and CP, also Cu and MDA levels. Besides, MDA and CAT levels of the animals increased with CP and SOD together, respectively. At the end of the study, Cd and Pb accumulation was observed in cattle, which were living near the road with intensive traffic for at least three years when compared with the control group. In addition, the results showed significant interactions among toxic heavy metals, physiological trace elements, enzymatic and non-enzymatic antioxidants and the lipid peroxidation.

Özet

Bu çalışmada, en az 3 yıldır anayol kenarında yaşayan sığırlarda bakır (Cu), çinko (Zn) ve demir (Fe) gibi bazı iz elementler, zehirli ağır metallerden olan kadmiyum (Cd) ve kurşun (Pb) ve antioksidan fonksiyonlar arasındaki olası ilişkinin tespit edilmesi amaçlandı. Çalışmada farklı ahırlarda yaşayan toplam 70 besi sığırı kullanıldı. Ana yola 0-500 metre mesafede yaşayan 54 (3-13 yaşlarında) sığır araştırma grubu olarak kullanıldı. Ana yola 2-3 km mesafede yaşayan 16 (3-12 yaşlarında) sığır ise kontrol grubunu oluşturdu. Hayvanlardan kan örnekleri toplandı ve Cd, Pb, Cu, Zn, Fe seviyeleri, lipid peroksidasyon göstergesi olan malondialdehid (MDA) ve antioksidasyon defans sistem indikatörleri olan eritrosit süperoksit dismutaz (SOD) aktivitesi, katalaz (CAT) aktivitesi ve plazma serüloplazmin (CP) seviyesi ölçüldü. Deneme grubu hayvanların Cd ve Pb seviyelerinin kontrol grubu hayvanlardan yüksek olduğu belirlendi (sırasıyla P<0.01 ve P<0.001). Bununla birlikte deneme grubunun Zn seviyesi kontrol grubundan düşük bulundu (P<0.001). MDA seviyesi kontrol grubundan yaklaşık üç kat, CP seviyesi ise yaklaşık iki kat daha yüksek tespit edildi (P<0.001). Pb ile MDA ve CP seviyeleri arasında gözle görülür şekilde bir ilişki olduğu gözlendi. Ayrıca, Fe ile CP ve Cu ile MDA arasında da önemli ölçüde korelasyon bulundu. Bunun yanında MDA ile CAT ve CP ile SOD seviyelerinin birlikte yükseldiği görüldü. Çalışma sonunda, anayol yakınında en az üç yıl yaşamış olan hayvanlarda, kontrol grubuyla karşılaştırıldığında Cd ve Pb birikimi olduğu gözlendi. Ayrıca, elde edilen sonuçlar zehirli ağır metaller, fizyolojik iz elementler, enzimatik ve enzimatik olmayan antioksidanlar ve lipid peroksidasyon göstergesi olan MDA arasında önemli düzeyde ilişki olduğunu gösterdi.
