变态会改变蝶类体内生物累积药物和内分泌干扰物的浓度：对水生-陆生补助转移的影响

水生昆虫是水生和陆地生态系统之间重要的生境间联系，因为它们的生命周期包括水生和陆地两个阶段。它们促进了能量和营养物质的流动，并在水生污染物向陆地环境的迁移过程中发挥着重要作用。本研究重点关注新出现的污染物（ECs）在环境中的归宿，尤其是源自废水并在水生昆虫体内积累的药物（PhACs）和干扰内分泌的化合物（EDCs）。通过对栖息在受废水影响的排水沟中的一种高产蝶类（毛翅目）--Silo nigricornis（Pictet，1834 年）进行原位研究，我们考察了 PhACs 和 EDCs 在蝶类水生和陆生生命阶段的生物累积和生物放大情况。我们观察到不同样本类型中 PhACs 和 EDCs 的最高浓度存在差异，包括水、生物膜和黑蓑蛾的不同生命阶段。在不同生命阶段的黑蓑蛾中，成年黑蓑蛾的氨基甲酸乙酯总浓度最高，有 17 种不同的氨基甲酸乙酯在蝶类组织中生物累积。与水生幼虫和蛹相比，大部分氨基甲酸乙酯在陆生成虫体内的浓度较高。随着发育，氨基甲酸乙酯的总浓度显著增加，显示陆生蝶类成虫体内的氨基甲酸乙酯浓度比蛹和幼虫高出41%。生物放大因素使人们了解到，在黑鳞笛鲷的至少一个变态阶段，体内大部分化合物的负荷都会增加。在两个变态阶段都观察到了生物放大的证据，某些化合物，如抗生素（阿奇霉素和替米考星）、内分泌干扰物（TCPP - 三[1-氯-2-丙基]磷酸酯和对羟基苯甲酸酯；对羟基苯甲酸甲酯和对羟基苯甲酸丙酯），从幼虫阶段到蛹阶段以及从蛹阶段到成虫阶段的浓度持续增加。在蝶类生命周期中观察到的污染物体内负荷增加模式强调了变态过程对成虫全代谢水生昆虫体内 PhACs 和 EDCs 浓度的影响。我们的研究结果强调了蝶形目成虫在将水生污染物（如 PhACs 和 EDCs）从水生环境迁移到陆地环境中的重要性。因此，我们的研究结果强调有必要将成体三翅目昆虫纳入栖息地质量评估，因为它们的影响超出了水生生态系统的范围。

期刊介绍： Freshwater Biology publishes papers on all aspects of the ecology of inland waters, including rivers and lakes, ground waters, flood plains and other freshwater wetlands. We include studies of micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment, provided that they have clear biological relevance. Studies may focus at any level in the ecological hierarchy from physiological ecology and animal behaviour, through population dynamics and evolutionary genetics, to community interactions, biogeography and ecosystem functioning. They may also be at any scale: from microhabitat to landscape, and continental to global. Preference is given to research, whether meta-analytical, experimental, theoretical or descriptive, highlighting causal (ecological) mechanisms from which clearly stated hypotheses are derived. Manuscripts with an experimental or conceptual flavour are particularly welcome, as are those or which integrate laboratory and field work, and studies from less well researched areas of the world. Priority is given to submissions that are likely to interest a wide range of readers. We encourage submission of papers well grounded in ecological theory that deal with issues related to the conservation and management of inland waters. Papers interpreting fundamental research in a way that makes clear its applied, strategic or socio-economic relevance are also welcome. Review articles (FRESHWATER BIOLOGY REVIEWS) and discussion papers (OPINION) are also invited: these enable authors to publish high-quality material outside the constraints of standard research papers.
