摘要

药品和个人护理用品（PPCPs）、金属纳米颗粒（NPs）等物质在环境中共存时，由于交互作用可能引起理化性质的改变，从而表现出有别于单一物质的复合毒性影响。分别对四环素和纳米铜、三氯生和纳米铜在水溶液中进行交互作用后物质理化性质的变化进行了研究。研究结果表明：四环素在与纳米铜作用过程中发生降解，浓度显著降低；三氯生在与纳米铜作用过程中主要吸附在纳米铜表面，引起浓度降低；另外，PPCPs作用于纳米铜时可能使其表面性质发生改变，从而显著促进Cu2+的溶出。因此PPCPs和纳米铜在水溶液中交互作用后理化性质都发生了不同类型、不同程度的改变。

Abstract

When substances

such as pharmaceutical and personal care products (PPCPs) and metal nanoparticles (NPs) coexist in environment

their physical-chemical properties might be changed under the interaction process

which would result in their combined toxicity different from the single one. After the interactions of tetracycline and copper nanoparticles (CuNPs)

triclosan and CuNPs in aqueous solution

and their physical-chemical property changes were investigated. The results indicated that the concentration of tetracycline decreasing mainly because of its degradation caused by CuNPs

and the adsorption of triclosan on CuNPs resulted in the triclosan concentration declining. In addition

the amount of dissolved Cu2+ from CuNPs was significantly increased probably due to its surface property change caused by tetracycline and triclosan. Thus

both the PPCPs and NPs had physical-chemical property changes in different type and various degrees under the interaction process.
