Abstract

Kidney and muscle samples were collected from 197 bovine and 33 porcine carcasses and liver and muscle from 115 poultry carcasses across the province. These tissues were analyzed for the following 13 elements, Ag, As, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Sb, Se, and Zn. The intent of the study was to determine normal background levels. Tissue concentration of these elements fell into five orders of magnitude ranging from < 10 μg kg(-1) for Ag to over 10 mg kg(-1) for Zn. Similar concentrations were observed in the three specie tissues being compared except for higher concentrations of Cd and Sb in bovine kidneys. In avian tissues Mo contents were higher in liver than muscle. When samples from all three species were grouped by age, no distinct trends were observed to indicate an increase in metal contents with age, with the exception of Cd in bovine kidneys.

摘要

从全省 197 头牛和 33 头猪的尸体以及 115 只家禽的肝脏和肌肉中采集了肾脏和肌肉样本。对这些组织进行了以下 13 种元素的分析：Ag、As、Cd、Co、Cr、Cu、Hg、Mo、Ni、Pb、Sb、Se 和 Zn。本研究的目的是确定正常背景水平。这些元素在组织中的浓度分为五个数量级，从 < 10 μg kg(-1) 的 Ag 到超过 10 mg kg(-1) 的 Zn。在所比较的三种物种组织中观察到了相似的浓度，除了牛肾中的 Cd 和 Sb 浓度较高。在禽类组织中，肝脏中的 Mo 含量高于肌肉。当按年龄将所有三种物种的样本分组时，没有观察到明显的趋势表明金属含量随年龄增加，除了牛肾中的 Cd 之外。
