Manufactured nanomaterials (MNMs) are increasingly incorporated into everyday products and thus are entering the environment via manufacturing, product use, and waste disposal. Still, understanding MNM environmental hazards and fates lags MNM industry growth. To catch up, keep pace, and influence future MNM safe design strategies, rapid safety assessments are needed. Bacteria are important ecological nanotoxicology targets to consider when assessing MNM safety: bacteria are exposed to MNMs in water, sewage, soils, and sediments, wherein they influence MNM fates; bacteria can also be impacted-with potential health and ecosystem consequences. Routinely using bacteria for assessing MNMs would promote effective management of the environmental risks of this rapidly growing industry, but appropriate protocols and policies for this assessment need to be instituted.
人造纳米材料（MNMs）越来越多地被应用于日常产品，因此通过制造、产品使用和废物处理等途径进入环境。然而，对于 MNM 的环境危害和命运的理解滞后于 MNM 产业的发展。为了迎头赶上、并驾齐驱以及影响未来 MNM 的安全设计策略，需要快速进行安全评估。在评估 MNM 的安全性时，细菌是重要的生态纳米毒理学研究目标：细菌在水、污水、土壤和沉积物中接触 MNMs，在这些环境中，细菌影响 MNM 的命运；细菌也可能受到影响，从而对健康和生态系统产生潜在影响。经常使用细菌来评估 MNMs 将有助于有效管理这个快速发展的行业的环境风险，但需要制定适当的协议和政策来进行这种评估。
