摘要：

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. © All Right Reserved.
