Abstract：
This study is addressing the potential toxicity concerns of crude oil in common carp (Cyprinus carpio) with the novel use of TiO2-NP for enhancing photocatalytic degradation of WSF of crude oil prepared under UV light or darkness. Blood samples were taken, and the biochemical parameters were analyzed. The levels of ALT, AST and ALP were significantly higher in fish exposed to UV-treated WSF. However, they were significantly lower in the groups exposed to UV-treated TiO2-NPs and the combination of WSF and TiO2-NPs. The levels of total protein, triglycerides, albumin and cholesterol were significantly lower in treatments exposed to UV-treated and dark-conditioned WSF compared to the control group, but they were significantly higher in fish exposed to UV-treated TiO2-NPs and the combination of WSF and TiO2-NPs compared to fish exposed under dark conditions and were not significantly different from the control group. The toxicity of UV-treated WSF was significantly higher than that of dark-conditioned WSF. The toxicity of TiO2-NPs was lower in the presence of UV and was similar to the control treatment. The results of the study suggests that photocatalytic TiO2-NPs and UV radiation reduce toxicity of the water-soluble fraction of crude oil on common carp.
摘要：
这项研究解决了鲤鱼（Cyprinuscarpio）中原油的潜在毒性问题，并使用了TiO2-NP来增强在紫外线或黑暗下制备的原油的WSF的光催化降解。采集了血样,并对生化指标进行了分析。ALT的水平，暴露于紫外线处理的WSF的鱼的AST和ALP明显更高。然而,在暴露于紫外线处理的TiO2-NP以及WSF和TiO2-NP组合的组中，它们显着降低。总蛋白质的水平，甘油三酯，与对照组相比，暴露于紫外线处理和黑暗条件WSF的处理中的白蛋白和胆固醇显着降低，但是，与在黑暗条件下暴露的鱼相比，暴露于紫外线处理的TiO2-NP以及WSF和TiO2-NP组合的鱼中的含量明显更高，并且与对照组没有显着差异。紫外线处理的WSF的毒性明显高于黑暗处理的WSF。在UV存在下TiO2-NP的毒性较低,与对照处理相似。研究结果表明，光催化TiO2-NP和紫外线辐射可降低原油水溶性部分对鲤鱼的毒性。
