The toxicity of some polycyclic aromatic hydrocarbons (PAHs) increases with ultraviolet (UV) radiation. The intensity of UV radiation varies within aquatic ecosystems, potentially providing reprieves during which tissue repair may occur. Transient/short-term PAH exposure prior to UV exposure may initiate metabolism/clearance, potentially affecting outcomes. Larval Sciaenops ocellatus were exposed to oil and UV radiation, using either variable photoperiods or pre-UV oil exposure durations. Shorter PAH exposures exhibited greater toxicity, as did exposure to shorter photoperiods. Environ Toxicol Chem 2018;37:2372-2379. © 2018 SETAC.
一些多环芳烃（PAHs）的毒性会随着紫外线（UV）辐射而增加。紫外线辐射在水生生态系统内的强度存在差异，这可能为组织修复提供喘息之机。在接受紫外线辐射之前，短暂/短期的 PAH 暴露可能会引发新陈代谢/清除，从而可能影响结果。使用可变光照周期或预先暴露于紫外线的时间，对幼鱼石首鱼进行了油和紫外线辐射暴露。较短的 PAH 暴露表现出更大的毒性，而较短的光照周期也表现出更大的毒性。环境毒理化学 2018；37:2372-2379。版权所有 2018 SETAC。
