4种潜在有毒元素的浓度(As,Cd,Hg,铅)在羽毛中进行了研究,肝脏,肾,和大cor骨(Phalacrocoraxcarbo)。组织样本是在匈牙利的Tisza-Jaszság中部自然保护区采集的。通过电感耦合等离子体发射光谱(ICP-OES)分析它们。调查的目的是分析这些野生鸟类各种组织中上述元素的金属负担,并为监测环境污染提供重要信息。在检查的潜在有毒元素中,没有观察到统计学上的性别差异,因此,在统计分析过程中,数据没有被分离。羽毛中汞的浓度最高,其次是肝脏,肾,还有骨头.在羽毛中检测到铅,水平最高,其次是肾脏,肝脏,还有骨头.在所有研究的组织中测定镉,其降序为:肾>骨>肝>羽毛。羽毛中砷浓度最高,其次是肝脏,肾,和骨骼浓度相同。所研究的潜在有毒元素在大cor不同组织中的检测浓度(羽毛,肝脏,肾,bone)meansthatthelivingareaofthisbirdsisnotishighlycontaminedtoincredhealthproblemsorposticsigns,甚至在动物中的其他不良影响。
Concentrations of 4 potentially toxic elements (As, Cd, Hg, Pb) were investigated in the
feather, liver, kidney, and bone of great cormorants (Phalacrocorax carbo). The tissue samples were taken at the Central Tisza - Jászság Nature Conservation Area in Hungary. They were analysed by inductively coupled plasma optical emission spectroscopy (ICP-OES). The goal of the investigation was to analyse the metal burden of the above-mentioned elements in the various tissues of these wild birds and to provide important information for monitoring the environmental pollution.Amongst the examined potentially toxic elements no statistical gender difference was observed, so the data were not separated based on them during the statistical analysis. The concentration of mercury was the highest in the
feather, followed by the liver, kidney, and bone. The lead was detected in the
feather with the highest level followed by the kidney, liver, and bone. The cadmium was determined in all investigated tissues with the next descending order: kidney > bone > liver >
feather. Highest arsenic concentration was measured in the
feather, followed by liver, kidney, and bone with the same concentration.The detected concentrations of the investigated potentially toxic elements in different tissues of great cormorants (feathers, liver, kidney, bone) means that the living area of this birds is not highly contaminated to induce health problems or toxic signs, or even other undesirable effect in the animals.
