The biotoxic effect of ZnO nanoparticles on three zooplankton [PDF]
, 2017 纳米氧化锌（ZnO-NPs）因其特殊的理化性质而在化妆品、医学抗菌、工业涂料等领域被广泛应用。其通过工业生产、商品使用、空气沉降、运输泄露、地表水径流等途径直接或间接汇入海洋环境，对海洋的生态系统构成潜在威胁。海洋中的浮游动物可以通过摄食影响或控制初级生产力，同时它们的种群动态变化又影响许多鱼类和其他动物资源群体的生物量。开展纳米氧化锌对浮游动物的毒性效应研究，对于了解纳米材料在水体中行为、评价浮游动物对纳米材料的响应、实现纳米材料环境危害性的合理评估具有十分重要的意义 ...
