Asian clams (Corbicula fluminea) have been extensively applied in biomonitoring and other environmental fields based on their high enrichment capacity and rapid response to pollutants. This review first summarizes the kinetic process of metals and organic pollutants enriched by C. fluminea and discusses the environmental behavior and application. The accumulation ability of Cu, Zn, and Mn were significantly higher than that of other metals, which were attributed to their high uptake rate constant and low elimination rate constant. The visceral mass was found to be the major burden tissue. However, large knowledge gaps existed regarding the accumulation capacity of C. fluminea for organic pollutants and nanoparticles. Moreover, physiological mechanisms underlying the accumulation of environmental pollutants were proposed. C. fluminea can improve the niche of benthic algae by ingesting pelagic algae, mitigating water eutrophication. It can also remove pathogens and parasites based on the biological assimilation of nonspecific immunity, interrupting disease transmission. The novel insight into the application of C. fluminea in wastewater treatment further broadens the range of pest management strategies and offers the feasibility of blocking the spread of invasive bivalves.

淡水底栖蛤(Corbicula fluminea)综述:蓄积能力、潜在生理机制和环境应用
亚洲蛤(Corbicula fluminea)以其高富集能力和对污染物的快速反应而被广泛应用于生物监测和其他环境领域。本综述首先总结了C富集金属和有机污染物的动力学过程。fluminea并讨论了环境行为和应用。Cu、Zn和Mn的富集能力显着高于其他金属,这归因于它们的高摄取速率常数和低消除速率常数。发现内脏肿块是主要的负担组织。然而,关于C的积累能力存在很大的知识差距。氟米尼亚用于有机污染物和纳米粒子。此外,还提出了环境污染物积累的生理机制。C. _ fluminea可以通过摄取远洋藻类来改善底栖藻类的生态位,从而减轻水体富营养化。它还可以根据非特异性免疫的生物同化作用清除病原体和寄生虫,阻断疾病传播。新颖洞察C的应用。废水处理中的fluminea进一步拓宽了害虫管理策略的范围,并提供了阻止侵入性双壳类动物传播的可行性。
