Engineered nanoparticles (ENPs), which have at least one dimension in the range of 1-100 nm, are used in the manufacture of various household and industrial products (e.g. personal care products, paints and coatings) to enable or enhance specific functions. ENPs can be released from these products to aquatic systems with runoff and wastewater effluents. A significant number of these ENPs in their ‘pristine’ forms (as ingredients in product formulations) have been shown to be toxic to aquatic and other organisms. Surface and groundwaters are sources of our drinking water as well as important components of our ecosystem, and thus research into the potential environmental and health impacts of increasing releases of ENPs to aquatic environments is an urgent necessity.

工程纳米颗粒(ENPs)至少有一个维度在1-100 nm的范围内，用于制造各种家用和工业产品(例如个人护理产品、油漆和涂料)，以实现或增强特定功能。ENPs可以从这些产品释放到具有径流和废水流出物的水生系统。相当数量的“原始”ENPs(作为产品配方中的成分)已被证明对水生生物和其他生物有毒。地表水和地下水是我们饮用水的来源，也是我们生态系统的重要组成部分，因此，研究向水环境释放越来越多的ENPs对环境和健康的潜在影响是迫切需要的。
