Palladium-based nanomaterials (Pd-NMs) have been mass produced and applied due to their remarkable properties and high earth abundance. This makes Pd-NMs come into frequent contact with the environment and enter the ecological environment. Comparative analysis of the toxicological data revealed that Pd-NMs have acute or chronic toxicity in both in vitro and in vivo biological receptors models, but only limited information has been provided on the possible environmental migration and transformation or concentration distribution in the environmental media of Pd-NMs. Therefore, a perspective is needed of the existing data to provide a more professional and comprehensive assessment of their ecotoxicity and sustainable development. This perspective describes the critical knowledge needed to assess their ecological risks. We recommend focusing on the current and future concentration and distribution of Pd-NMs in the environment, guiding the assessment of the full-cycle ecotoxicity of Pd-NMs, and strongly encourage the quantitative measurement of the concentration level of Pd-NMs in the real environment.

钯基纳米材料的观点：绿色合成，生态毒性和风险评估

钯基纳米材料（Pd-NMs）由于其卓越的性能和高的地球丰度而得到了大规模生产和应用。这使得Pd-NMs经常与环境接触并进入生态环境。毒理学数据的比较分析表明，Pd-NMs在体外和体内均具有急性或慢性毒性生物受体模型，但仅提供了有关Pd-NMs环境介质中可能的环境迁移和转化或浓度分布的有限信息。因此，需要对现有数据进行透视，以便对其生态毒性和可持续发展进行更专业和全面的评估。该观点描述了评估其生态风险所需的关键知识。我们建议着眼于当前和未来环境中Pd-NMs的浓度和分布，指导评估Pd-NMs的全周期生态毒性，并强烈建议对实际中Pd-NMs的浓度水平进行定量测量环境。
