Bioindicators have become increasingly popular and have contributed significant amounts of useful information to the process of managing water resources. The ability of a species (or species assemblage) to adapt to a certain range of chemical, physical, and biological conditions is one criterion that can be used to assess the quality of its surrounding environment. Planktons that react quickly to changes in their environment have proven to be particularly valuable, and the identification of certain indicator species has become increasingly common in the process of determining the quality of the water. The “health” of an aquatic system can be inferred from the presence or absence of plankton, which act as early warning signals. When compared with the expense of assessing harmful contaminants, the overall cost of conducting routine monitoring of biological communities is far lower and has a higher degree of reliability. The ability of bioindicators to identify indirect biotic effects of pollutants, which is something that many physical or chemical tests are unable to do, is another advantage of using bioindicators. Different aquatic species as bioindicators tolerate different environmental conditions, and their different tolerances to particular environments help in identifying a particular environmental condition. Phytoplankton species like Euglena viridis, Oscillatoria limosa, Nitzschia palea, and Scenedesmus quadricauda, and zooplankton species like Branchionus sp., Molina sp., Keratella cochlearis, Daphnia sp., and Cyclopus sp. indicate water pollution. This review's objective is to highlight some recent research on planktons, focusing on their capabilities and opportunities for application as bioindicators of water quality. 摘要 生物指标变得越来越受欢迎, 并为水资源管理过程提供了大量有用的信息。一个物种 (或物种组合)在一定范围的化学条件、物理条件和生物条件下的适应能力是用于评估其周围环境质量的标准之一。事实证明, 对环境变化作出快速反应的浮游生物特别有价值, 并且在确定水质的过程中, 某些指示物种的识别已变得越来越普遍。水生系统的“健康”能通过浮游生物的存在或不存在加以推断, 这些浮游生物充当了早期预警信号。与评估有害污染物所需的费用相比, 对生物群落进行常规监测的总体成本要低得多, 并且可靠性更高。生物指示剂能够识别污染物的间接生物效应, 这是许多物理或化学检验无法做到的, 这也是使用生物指示剂的另一个优势。作为生物指示剂的不同水生物种能耐受不同的环境条件, 它们对特定环境的不同耐受性有助于识别特定的环境条件。绿眼虫藻、泥生颤藻、谷皮菱形藻、四尾栅藻等浮游植物, 以及臂尾轮属、莫利纳属 (Molina sp.)、螺形龟甲轮虫、水蚤、剑水蚤等浮游动物的存在表明水体受到污染。本篇述评旨在重点介绍浮游生物的一些最新研究, 聚焦于其作为水质生物指示剂的能力和机会。 Los bioindicadores se han vuelto cada vez más populares y han aportado cantidades significativas de información útil para el proceso de gestión de los recursos hídricos.
