生物挥发性有机化合物 (BVOC) 从植被释放到大气中。 BVOC 通过一系列功能有助于维持生态系统的可持续性，但是，VOC 在高浓度下会改变对流层光化学并对生物有机体产生负面影响。由于 BVOC 在生态系统和环境可持续性中发挥着关键作用，因此受到全球变化生物学家的特别关注。为了了解植物挥发性有机化合物排放如何影响剂量反应背景下的应激反应，应评估剂量反应。该评论共同记录了植物排放的挥发性有机化合物对外部刺激的类似毒物兴奋反应。毒物兴奋效应是一种普遍的双相剂量反应现象，其中对低剂量的反应在高剂量时以相反的方式起作用。这些集体发现表明，在未来的研究中应考虑可能改变 BVOC 排放的低水平压力的生态影响。该评论促进了对影响全球多个地区的生物系统与环境变化之间的相互作用的新见解，并为推进危害评估测试策略和协议奠定了基础，从而为决策者提供了制定环境标准的充足数据。 (C) 2018 Elsevier Ltd. 保留所有权利。
Biogenic volatile organic compounds (BVOCs) are released to the atmosphere from vegetation. BVOCs aid in maintaining ecosystem sustainability via a series of functions, however, VOCs can alter tropospheric photochemistry and negatively affect biological organisms at high concentrations. Due to their critical role in ecosystem and environmental sustainability, BVOCs receive particular attention by global change biologists. To understand how plant VOC emissions affect stress responses within a dose-response context, dose responses should be evaluated. This commentary collectively documents hormetic-like responses of plant-emitted VOCs to external stimuli. Hormesis is a generalizable biphasic dose response phenomenon where the response to low doses acts in an opposite way at high doses. These collective findings suggest that ecological implications of low-level stress that may alter BVOC emissions should be considered in future studies. This commentary promotes new insights into the interface between biological systems and environmental change that influence several parts of the globe, and provide a base for advancing hazard assessment testing strategies and protocols to provide decision makers with adequate data for generating environmental standards.
