摘要

测定了在波兰东部地区采集的6种猛禽肝脏中铅、镉、镍、铬和汞的浓度。冗余分析(RDA)表明，汞和铬浓度升高与取食雀形目动物有直接关系。专门以捕获小型哺乳动物为食物来源的迅猛龙与其他迅猛龙相比，肝脏中铅和镉的浓度更高。与镉不同的是，我们发现普通秃鹰肝脏中的铅浓度与雀鹰相比有统计学上的显著差异。尽管苍鹰和雀鹰都捕食鸟类，但只有雀鹰体内的汞含量明显高于雀鹰。雀鹰体内汞含量高可能与用于种子敷料的抗真菌物质中汞的使用有关。

Heavy metals in livers of raptors from Eastern Poland – the importance of diet composition

Concentrations of Pb, Cd, Ni, Cr and Hg were determined in livers of six species of raptors collected in the area of Eastern Poland. Redundancy analysis (RDA) showed that elevated Hg and Cr concentrations were directly related to feeding on passerines. Raptors that specialised in seizing small mammals as a source of food revealed higher hepatic concentrations of Pb and Cd in comparison with other raptors. Unlike Cd, we found statistically significant differences in the Pb concentrations in livers of Common buzzards as compared to Sparrowhawks. In spite of the fact that both Goshawks and Sparrowhawks hunt birds, only the latter species had accumulated significantly more mercury. The high concentrations of Hg in Sparrowhawks could be related to the use of mercury in antifungal substances for seed dressing.

期刊介绍： The Belgian Journal of Zoology is an open access journal publishing high-quality research papers in English that are original, of broad interest and hypothesis-driven. Manuscripts on all aspects of zoology are considered, including anatomy, behaviour, developmental biology, ecology, evolution, genetics, genomics and physiology. Manuscripts on veterinary topics are outside of the journal’s scope. The Belgian Journal of Zoology also welcomes reviews, especially from complex or poorly understood research fields in zoology. The Belgian Journal of Zoology does no longer publish purely taxonomic papers. Surveys and reports on novel or invasive animal species for Belgium are considered only if sufficient new biological or biogeographic information is included.
