  • 摘要: 在自然或人为作用下，纳米晶体能够在自然环境中广泛且稳定存在，并具有独特的结构和表面性质.准确预测纳米晶体在环境中的迁移转化及其与其它化合物或生物体的相互作用已成为环境科学领域的热点问题.纳米晶体的结构特征受其生长过程中水化学条件、环境因素等影响，导致其晶型和暴露晶面的不同，显著改变纳米晶体的溶解、吸附、催化等环境行为及其对微生物、甲壳动物、哺乳动物等的毒性效应.本文从环境中纳米晶体的种类和性质、不同晶型和暴露晶面的形成机制及影响因素、晶型和暴露晶面对纳米晶体环境行为和效应的影响等方面进行综述，为研究纳米晶体对营养元素及有毒有害物质的生物地球化学循环过程的影响机制提供科学依据.
    Abstract: Nanocrystals possess unique structure and surface properties and are prevalently present in the environment due to natural and anthropogenic processes. In recent years, extensive research attention has focused on understanding the migration and transformation of nanocrystals in the environment and their interactions with other compounds or organisms. The structural characteristics of nanocrystals are influenced by water chemistry and environmental conditions during the formation of nanocrystals. As a result, nanocrystals with different crystalline phases and exposed facets exist, and exhibit differential environmental behaviors such as dissolution, adsorption, and catalysis, as well as posing toxic effects to microorganisms, crustacean and mammals. This review synthesizes recent advances in understanding the mechanisms of and factors affecting the occurrence of nanocrystals with different crystalline phases and exposed facets in the environment, and the environmental behavior and impact of these nanocrystals, which provides the scientific basis for exploring the role of nanocrystals in the biogeochemical cycling of nutrient and toxic elements.

摘要: 在自然或人为作用下，纳米晶体能够在自然环境中广泛且稳定存在，并具有独特的结构和表面性质.准确预测纳米晶体在环境中的迁移转化及其与其它化合物或生物体的相互作用已成为环境科学领域的热点问题.纳米晶体的结构特征受其生长过程中水化学条件、环境因素等影响，导致其晶型和暴露晶面的不同，显著改变纳米晶体的溶解、吸附、催化等环境行为及其对微生物、甲壳动物、哺乳动物等的毒性效应.本文从环境中纳米晶体的种类和性质、不同晶型和暴露晶面的形成机制及影响因素、晶型和暴露晶面对纳米晶体环境行为和效应的影响等方面进行综述，为研究纳米晶体对营养元素及有毒有害物质的生物地球化学循环过程的影响机制提供科学依据.
