Abstract

Biodiversity-associated ecosystem services such as pollination and biocontrol may be severely affected by emerging nano/micro-plastics (NMP) pollution. We synthesized the little-explored effects of NMP on pollinators and biocontrol agents on the organismal, farm and landscape scale. For instance ingested NMP trigger organismal changes from gene expression, organ damage to behavior modifications. At the farm and landscape level, NMP will likely amplify synergistic effects with other threats such as pathogens and antibiotics, and may alter landscape properties such as floral resource distributions in high NMP concentration areas, what we call NMP islands. It is essential to understand the functional exposure pathways of NMP on pollinators and biocontrol agents to comprehensively evaluate the risks for agricultural ecosystems and global food security.

农业景观中的纳米/微塑料效应：对授粉、生物害虫控制和粮食安全的一个被忽视的威胁

与生物多样性相关的生态系统服务（如授粉和生物控制）可能会受到新出现的纳米/微塑料（NMP）污染的严重影响。我们研究了 NMP 在生物体、农场和景观尺度上对授粉者和生物控制剂的影响，但对这些影响的研究甚少。例如，摄入的 NMP 会引发生物体的变化，包括基因表达、器官损伤和行为改变。在农场和景观层面，NMP 可能会扩大与病原体和抗生素等其他威胁的协同效应，并可能改变景观特性，如 NMP 高浓度区域（我们称之为 NMP 岛）的花卉资源分布。要全面评估 NMP 对农业生态系统和全球粮食安全的风险，就必须了解 NMP 对授粉昆虫和生物控制剂的功能性暴露途径。
