紫外线辐射 (UVR) 具有三个重要特性，这些特性结合起来使其成为一种强大的环境力量。其中包括造成损害的可能性：紫外线每个光子携带的能量比到达地球表面的任何其他波长都多。众所周知，这种高能光子会损坏许多生物分子，例如 DNA 和蛋白质。此外，它们还可以引发一系列氧化还原反应，形成活性氧（ROS），对细胞和组织造成氧化应激。第二个特性是普遍存在的：由于初级生产者和大多数视觉捕食者（例如鱼类）对光的依赖，也必然暴露在有害水平的紫外线下。第三，紫外线和其他环境因素的综合作用可能会产生协同效应，例如有机污染物的光活化和光敏化。在自然环境中，溶解有机物（DOM）的浓度和栖息地深度是控制鱼类经历的紫外线照射程度的两个主要因素。其他因素包括植被覆盖度、悬浮颗粒物质、pH 值和水文特征以及场地位置（纬度、海拔）。对鱼类的潜在影响包括直接 DNA 损伤，导致胚胎和幼鱼死亡、成鱼和幼鱼晒伤，以及间接氧化应激、光毒性和光敏性。
Ultraviolet radiation (UVR) possesses three important properties that combine to make it a potent environmental force. These include the potential to induce damage: UVR carries more energy per photon than any other wavelength reaching the Earth’s surface. Such highly energetic photons are known to damage many biological molecules, such as DNA and proteins. In addition, they can initiate a series of redox reactions to form reactive oxygen species (ROS), which cause oxidative stress to cells and tissues. The second property is ubiquity: owing to their dependence on light, primary producers and most visual predators, such as fish, are also necessarily exposed to damaging levels of UVR. Thirdly, the combined effect of UVR and additional environmental factors may result in synergistic effects, such as the photoactivation of organic pollutants and photosensitisation. In natural environments, the concentration of dissolved organic matter (DOM) and habitat depth are the two main factors controlling the degree of UVR exposure experienced by fish. Additional factors include vegetation coverage, particulate materials in suspension, pH and hydrological characteristics, and site location (latitude, elevation). The range of potential effects on fish includes direct DNA damage resulting in embryo and larval mortality, and adult and juvenile sunburn, as well as indirect oxidative stress, phototoxicity and photosensitisation.
