这项研究检查了铝的浓度,Ca,Cd,Cr,Cu,Fe,K,Mg,Mn,Na,Ni,Pb,金jack狼(n=163)和红狐狸(n=64)的肝脏和肾脏样品中的锌。此外,我们研究了性别如何影响两个物种的元素浓度,而在金狼的情况下,浓度水平如何受到年龄的影响。肝脏是铜最重要的储存器官,Fe,Mn,Zn,而肾中的Cd和Na则在狼和狐狸中。我们发现狐狸样品中任何选定元素的浓度都没有与性别相关的差异。在狼狼中,铝的平均浓度,Mn,男性肾脏中的锌含量明显更高,而雌性肝脏中Zn和Cu的浓度较高。我们的结果表明,中食动物不会发生生物积累过程。铅和镉的浓度落在犬科动物公认的正常范围内,并且低于受检物种器官的毒性水平。Cr的浓度,Cu,Fe,Mn,和锌远低于两个物种的两个器官的毒性水平,有轻微的缺铁迹象,Mn,和锌在狼和狐狸的肾脏。与其他欧洲研究中心的毒性水平和结果相比,目前的研究表明,生活在索莫吉县检查区域的物种,匈牙利,通常暴露于低水平的环境污染。
This study examined the concentrations of Al, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn in the liver and kidney samples of golden jackals (n = 163) and red foxes (n = 64). Additionally, we studied how sex affected element concentration in both species, and in the case of golden jackals, how concentration levels were affected by age.Liver was the most important storage organ for Cu, Fe, Mn, and Zn, while kidney for Cd and Na in jackals and foxes.We found no sex-related differences in concentration of any of the selected elements in fox samples. In jackals, the mean concentrations of Al, Mn, and Zn were significantly higher in kidneys of males, while Zn and Cu had higher concentrations in female livers. Our results suggest bioaccumulation processes do not occur in mesocarnivores.Lead and Cd concentrations fell within ranges accepted as normal for canine species and were below toxic levels in the organs of the examined species. Concentrations of Cr, Cu, Fe, Mn, and Zn were far below the toxic levels in both organs of both species, with a slight sign of deficiency of Fe, Mn, and Zn in jackal and fox kidneys. In comparison with toxicity levels and results from other European study sites, the current study demonstrated that species living in the examined area of Somogy County, Hungary, are generally exposed to low levels of environmental contamination.
