Dumping waste materials into aquatic ecosystems leads to pollution, which directly and indirectly poses a danger to all life forms. Currently, huge quantities of wastes are generated at a global scale with varying constituents, including organic fractions, emerging contaminants and toxic metals. These wastes release concentrated contaminants (leachates), which are lethal for all ecosystems around the globe because they contain varying concentrations of chemical constituents with BOD and COD in the order of 2 × 10-2.7 × 10 mg/L, and 3.4 × 10-3.8 × 10 mg/L, respectively. Herein, in-depth knowledge of municipal solid waste dumping into the aquatic ecosystems, changes in physicochemical characteristics, availability of in-/organic contaminants, and long-term unhealthy effects are presented. Moreover, an attempt has been made here to summarize the facts related to identifying the deadly impacts of waste on different ecosystem components. The unresolved challenges of municipal waste management are emphasized, which will help employ suitable waste management techniques and technologies to conserve the everlasting freshwater resources on earth.
将废物倾倒入水生生态系统会导致污染，这直接或间接地对所有生命形式构成威胁。目前，全球范围内产生了大量废物，其成分各不相同，包括有机部分、新兴污染物和有毒金属。这些废物释放出浓缩的污染物（浸出液），对全球所有生态系统都构成致命威胁，因为它们含有不同浓度的化学成分，BOD 和 COD 的浓度分别为 2×10-2.7×10 mg/L 和 3.4×10-3.8×10 mg/L。在此，深入探讨了将城市固体废物倾倒入水生生态系统、理化特性变化、无机/有机污染物的可利用性以及长期不良影响等问题。此外，本文还试图总结与废物对不同生态系统成分的致命影响有关的事实。强调了城市废物管理中尚未解决的挑战，这将有助于采用合适的废物管理技术和技术来保护地球上永恒的淡水资源。
