即使有些对生物学功能至关重要,超过可耐受的生理极限的重金属的积累对野生动物也有潜在的毒性。本研究旨在调查与环境相关的重金属(As,Cd,Cu,Fe,Hg,Mn,Pb,和锌)在羽毛中,肌肉,心,肾,和野生鸟类的肝脏组织(金鹰[Aquilachrysaetos],sparrowhawk[Accipiternisus],和来自哈塔省的白鹭[Ciconiaciconia]),土耳其南部微波消解后,通过经过验证的ICP-OES分析方法确定组织的金属浓度。通过统计分析确定物种/组织中金属的浓度差异以及必需/非必需金属之间的相关性。根据结果,Fe(326.87±3.60mgkg-1)含量最高,和Hg(0.09±0.00mgkg-1)在所有组织中的平均浓度最低。与文献相比;铜,Hg,Pb,和Zn浓度较低;Cd,Fe,锰浓度较高。As与所有要素之间的相关性;Cd和Cu,Fe;Hg和Cu,Fe,Zn;Pb和所有必需品均呈显著阳性。在结论中,而必需的铜,Fe,和锌低于阈值,不构成风险,Mn接近阈值。因此,定期监测生物指标中的污染物浓度是早期确定生物放大趋势和防止野生动物生态潜在毒性胁迫的关键必要条件。
Even if some are essential for biological functions, the accumulation of heavy metals above tolerable physiological limits is potentially toxic to also wild animals. The present study aimed to investigate concentrations of environmentally relevant heavy metals (As, Cd, Cu, Fe, Hg, Mn, Pb, and Zn) in feathers, muscle, heart, kidney, and liver tissues of wild birds (golden eagle [Aquila chrysaetos], sparrowhawk [Accipiter nisus], and white stork [Ciconia ciconia]) from Hatay province, southern Turkey. The metal concentrations of tissues were determined by a validated ICP-OES analysis method after microwave digestion. The concentration differences of metals in species/tissues and the correlations between essential/non-essential metals were determined by statistical analysis. According to the results, Fe (326.87±3.60 mg kg-1) had the highest, and Hg (0.09±0.00 mg kg-1) had the lowest mean concentration in all tissues. Compared to the literature; Cu, Hg, Pb, and Zn concentrations were lower; Cd, Fe, and Mn concentrations were higher. The correlations between As and all essentials; Cd and Cu, Fe; Hg and Cu, Fe, Zn; Pb and all essentials were significantly positive. In the conclusion, while essential Cu, Fe, and Zn are below the threshold value and do not pose a risk, Mn is close to the threshold value. Therefore, periodically monitoring the pollutant concentrations in bioindicators is a key necessity for the early determination of biomagnification trends and prevention of potential toxic stress on wildlife ecology.
