摘要:
    以日本虎斑猛水蚤为实验生物，研究了纳米二氧化钛（nTiO2）及与菲、芘联合的急性毒性效应.实验结果表明：当ρ(nTiO2)≤5 mg/L时对日本虎斑猛水蚤的存活率无显著性的影响，而当ρ(nTiO2)≥20 mg/L时则有显著性影响；菲、芘都可与纳米二氧化钛（1 mg/L）联合表现出比单一污染物更大的毒性效应，其中芘与纳米二氧化钛存在显著的联合协同效应.研究表明，纳米材料会与环境中其他的污染物相互作用，从而对水生生物表现出间接的毒性作用，因此在海洋环境中纳米材料的潜在危害不容忽视
Abstract:
The single and joint toxicity of nanosized titanium dioxide ( nTiO2) with phenanthrene and pyrene to Tigriopus japonicus was investigated seperately by measuring 96h survival rates.The results showed that there was no significant mortal effects of nTiO2 on Tigriopus japonicus in concentrations ≤5 mg/L，but it made significant differences between control and exposure conditions when concentrations ≥20 mg/L.It also showed that nTiO2 aggregates could enhance the toxicity of phenanthrene and pyrene to some degree.Thus，we should not only focus on the inherent toxicity of manufactured nanoparticles，but also on the interactions with other compounds in aqueous suspension
