In recent years, with the development of the global economy, water pollution has increased. Pollutants migrate, accumulate, and diffuse in aquatic environments. Most of the pollutants eventually enter aquatic organisms. The accumulation of pollutants affects the development and reproduction of organisms, and many pollutants have teratogenic, carcinogenic, and/or mutagenic effects. Aquatic organisms in estuaries and coastal areas are under pressure due to both salinity and pollutants. Among them, salinity, as an environmental factor, may affect the behavior of pollutants in the aquatic environment, causing changes in their toxic effects on fishes. Salinity also directly affects the growth and development of fishes. Therefore, this paper focuses on metals and organic pollutants and discusses the toxic effects of pollutants on fish under different salinities. This research is of great significance to environmental protection and ecological risk assessment of aquatic environments.
近年来，随着全球经济的发展，水污染日益严重。污染物在水生态环境中迁移、积累和扩散。大部分污染物最终进入水生生物体内。污染物的积累影响生物的生长和繁殖，许多污染物具有致畸、致癌和/或致突变作用。河口和沿海地区的水生生物受到盐度和污染物的双重压力。其中，盐度作为环境因素，可能会影响污染物在水生态环境中的行为，导致其对鱼类的毒性作用发生变化。盐度也会直接影响鱼类的生长和发育。因此，本文主要关注金属和有机污染物，并讨论不同盐度下污染物对鱼类的毒性作用。这项研究对于环境保护和水生环境生态风险评估具有重要意义。
