Sığırlarda Kurşunun Sebep Olduğu Zehirlenme

Bu çalışmada, Eskişehir'deki bir akü fabrikası etrafında otlayan sığırlarda karşılaşılan üç zehirlenme olayının kurşundan ileri gelip gelmediğinin araştırılması amaçlandı. Bu sebeple, gerek ölen hayvanlardan alınan mide içeriği, barsak içeriği, akciğer, dalak, böbrek, karaciğer ve kalp ile gerekse hayvanların yediği arpa ve saman ömeklerinde kurşun analizi yapıldı. Bunun için ömeklerin organik madde kısmı magnezyum asetat karşısında kuru külleştirme ile yıkımlandıktan sonra, kurşun atomik absorpsiyon spektrofotometresiyle ölçüldü. Analiz edilen tüm ömeklerde 0.78-121.01 ppm arasında kurşun kalıntısı bulundu; bunlarda belirlenen ortalama kurşun düzeyleri ppm olarak şöyledir : Mide içeriği 16.49, barsak içeriği 10.99, akciğer 2.10, dalak 2.23, böbrek hilusu 96.82, böbrek korteksi 43.26, karaciğer 47.29, kalp 1.43, arpa 4.42 ve saman 0.78 . Elde edilen bulguların değerlendirilmesi ile olayların akut kurşun zehirlenmesi olduğu sonucuna varıldı.

Acute poisoning case caused by lead, in cows

The purpose of this study was to find out three poisoning cases at grazing cattle if the causal was lead or not around a battery repairing factory in Eskişehir. For this reason, the samples was obtained (died cattle alsa barley and straw samples eaten by cattle) and analyzed the level of the lead. Following the organic content of the samples had been ashed by magnesium asetate and then lead was measured by atomic absorption spectrophotometry. All of the analyzed samples were found to contain the lead residues ranging from 0.78 ppm to 121.01 ppm. Average levels of lead in the samples were as ppm as follows; stomach content 16.49, intestine content 10.99, lung 2.10, spleen 2.23, renal hilus 96.82, renal cortex 43 .26, liver 47.29, heart 1.43, barley 4.42 and straw 0.78 . It was concluded from the interpretation of the analysis results that those events in cattle was an acute lead poisoning.
