Abstract

The aim of this study was to determine the accumulation of selected heavy metals (Pb, Cd, Hg, As) in meat and liver of cattle. The animals were divided into four age-groups which allowed the analysis of statistical-mathematical correlations between the age of the animals and contamination of meat. The research material for determination of heavy metal levels was taken from the longissimus back muscle (m. longissimus dorsi) and samples from the tail lobe of the liver. Analysis showed that contamination by Cd and Pb is clearly dependent on the age of the animal.

摘要

本研究旨在确定牛的肉和肝脏中选定重金属（Pb、Cd、Hg、As）的积累情况。将动物分为四个年龄组，以便分析动物年龄与肉污染之间的统计数学相关性。为了测定重金属水平，研究材料取自背最长肌（m. longissimus dorsi）和肝尾叶样本。分析表明，Cd 和 Pb 的污染明显取决于动物的年龄。
