Biomonitoring is the qualitative observation and the measurement of biosphere parameters aimed at modelling the environment, evaluating its quality, and studying the effects of alterations on different ecological levels. In this work, trace metal concentrations were assessed using non-destructive biomonitoring tools as blood and feathers of the allochthonous aquatic bird , collected within two areas of the Palermo metropolitan area, Sicily, differently exposed to air pollution: Parco D'Orleans, in a central urban location, and Monreale, southwest of the city centre. Higher concentrations in both blood and feathers collected in Parco D' Orleans were found for lead, tin and selenium, but the same was not observed for other metals. The concentrations were not above physiological tolerance in any case. The comparison between blood and feathers allowed to realize that the latter are more useful for biomonitoring analyses, as they are indicative of both external contamination and bioaccumulation. Treatment with nitric acid highlighted that the feathers collected in Parco D' Orleans had higher metal bioaccumulation than the ones collected in Monreale; however, the treatment needs standardization. The present study confirms that feathers and blood from are a convenient and non-destructive sampling tool for metal contamination analysis.
生物监测是对生物圈参数进行定性观察和测量，旨在对环境进行建模、评估其质量，并研究不同生态层面变化的影响。在这项工作中，使用非破坏性生物监测工具对来自西西里岛巴勒莫大都市区两个不同空气污染暴露区域的外来水鸟的血液和羽毛中的痕量金属浓度进行了评估：位于城市中心的奥尔良公园和市中心西南部的蒙雷阿莱。在奥尔良公园采集的血液和羽毛中，铅、锡和硒的浓度较高，但其他金属并非如此。在任何情况下，这些浓度都未超过生理耐受范围。血液和羽毛之间的比较表明，羽毛对于生物监测分析更有用，因为它们既表明了外部污染又表明了生物累积。用硝酸处理突出显示，在奥尔良公园采集的羽毛比在蒙雷阿莱采集的羽毛具有更高的金属生物累积；然而，该处理需要标准化。本研究证实，鸟类的羽毛和血液是用于金属污染分析的便捷且非破坏性的采样工具。
