Environmental pollution, for example with metals, can significantly affect the ecosystem balance leading to severe changes. Biologically active pigments are relevant for the appearance and condition of birds. Melanin and carotenoid particles are the most frequently deposited pigments in avian integument. They are responsible for the majority of colors of bird plumage. The phenotypic expression can be affected by metal contamination. It can be manifested as color bleaching or differences in the size of plumage badges. In this study, we performed a comprehensive review of related studies in order to estimate the underlying population effect of this potential dependency. The study is based on the review of the literature regarding several avian species. It was designed to identify an area where the effect of the exposure is still poorly known. The analysis was specifically conducted to investigate the correlation between trace element concentration and eumelanin deposition. Moreover, we searched for factors that could affect spectral properties of feathers with carotenoid-based pigmentation. As a result, we found carotenoid-based pigmentation to be of a good use in terms of visual condition assessment. Changes in melanin-based pattern should be analyzed separately for eu- and pheomelanin as well as for a range of essential and toxic elements. Comprehensive studies on the subject are still scarce. Therefore, the issue requires further investigation.
环境污染，例如金属污染，会显著影响生态系统平衡，导致严重变化。生物活性色素与鸟类的外观和状况相关。黑色素和类胡萝卜素颗粒是鸟类体表最常沉积的色素。它们决定了鸟类羽毛的大部分颜色。表型表达会受到金属污染的影响。这可能表现为羽毛褪色或羽饰大小的差异。在本研究中，我们对相关研究进行了全面综述，以评估这种潜在依赖性对种群的潜在影响。该研究基于对几种鸟类物种的文献综述。其目的是确定一个暴露影响仍知之甚少的领域。具体分析是为了研究微量元素浓度与真黑色素沉积之间的相关性。此外，我们还寻找了可能影响基于类胡萝卜素色素沉着的羽毛光谱特性的因素。结果，我们发现基于类胡萝卜素的色素沉着在视觉状况评估方面很有用。基于黑色素的图案变化应分别针对真黑色素和褐黑色素以及一系列必需元素和有毒元素进行分析。关于该主题的综合研究仍然很少。因此，这个问题需要进一步调查。
