淡水生态系统受到热浪等极端天气的强烈影响，预计未来热浪的频率和强度将增加。除了这些极端气候之外，淡水领域还受到人类活动排放的各类化学品的影响。目前，关于危险废物和化学品的联合接触如何影响淡水生态系统的结构和功能的知识有限。在这里，我们回顾了现有的文献描述的HWs和化学品对不同层次的生物组织的单一和组合的影响，以获得一个整体的看法，其潜在的相互作用的影响。我们只发现了几项研究（本综述中包括的61项研究中的13项），这些研究调查了HWs与化学污染相结合的生物效应。所报告的危险废物和化学品的相互作用不仅在不同的营养级内有很大的差异，而且还取决于所研究的种群或个体的终点。因此，也由于现有的研究数量很少，在生物组织的任何层面上都无法突出一致的相互作用效应。此外，我们发现了对单一物种和种群实验的不平衡，只有五项研究使用了多营养方法。这导致了对相关社区和生态系统一级终点的知识空白，从而阻碍了对可能损害食物网稳定性的重要间接影响的探索。此外，这一知识差距损害了化学品风险评估的有效性和我们保护生态系统的能力。最后，我们强调了将极端事件整合到多个压力源研究中的紧迫性，并提供了具体的建议，以指导这方面的进一步实验研究。我们回顾了现有的文献描述的单一和组合的影响，热浪和化学品对不同层次的生物组织。我们发现只有少数研究将这些压力因素结合起来。此外，我们强调对单一物种和人口的实验不平衡。这导致了相关社区和生态系统层面端点的知识缺口，这阻碍了对可能损害食物网稳定性的重要间接影响的探索。最后，我们强调了将极端事件整合到多个压力源研究中的紧迫性，并提供了指导这方面进一步实验研究的建议。
Freshwater ecosystems are strongly influenced by weather extremes such as heatwaves (HWs), which are predicted to increase in frequency and magnitude in the future. In addition to these climate extremes, the freshwater realm is impacted by the exposure to various classes of chemicals emitted by anthropogenic activities. Currently, there is limited knowledge on how the combined exposure to HWs and chemicals affects the structure and functioning of freshwater ecosystems. Here, we review the available literature describing the single and combined effects of HWs and chemicals on different levels of biological organization, to obtain a holistic view of their potential interactive effects. We only found a few studies (13 out of the 61 studies included in this review) that investigated the biological effects of HWs in combination with chemical pollution. The reported interactive effects of HWs and chemicals varied largely not only within the different trophic levels but also depending on the studied endpoints for populations or individuals. Hence, owing also to the little number of studies available, no consistent interactive effects could be highlighted at any level of biological organization. Moreover, we found an imbalance towards single species and population experiments, with only five studies using a multitrophic approach. This results in a knowledge gap for relevant community and ecosystem level endpoints, which prevents the exploration of important indirect effects that can compromise food web stability. Moreover, this knowledge gap impairs the validity of chemical risk assessments and our ability to protect ecosystems. Finally, we highlight the urgency of integrating extreme events into multiple stressors studies and provide specific recommendations to guide further experimental research in this regard. We reviewed the available literature describing the single and combined effects of heatwaves and chemicals on different levels of biological organization. We found that only few studies addressed these stressors in combination. Moreover, we highlight the imbalance towards single species and population experiments. This results in a knowledge gap for relevant community‐ and ecosystem‐level endpoints, which prevents the exploration of important indirect effects that can compromise food web stability. Finally, we highlight the urgency of integrating extreme events into multiple stressors studies and provide recommendations to guide further experimental research in this regard.
