ABSTRACT

Rapid development has been associated with mercury pollution in the aquatic environment, leading to mercury toxicity in fish and other aquatic organisms. Histopathological abnormalities such as hyperplasia, inflammation, and necrosis have been observed in various fish tissues as a result of mercury contamination based on organic mercury (methylmercury) and inorganic mercury (mercuric chloride) exposure via dietary or water exposure, respectively, with different duration doses of mercury. Knowing that tissue changes occurred at an important part of each organ that played various critical roles in the normal physiological actions of fish, it is critical to understand how fish respond to mercury contamination and how this heavy metal element affects their general well-being. This review paper focuses on major tissue histopathology changes in response to mercury toxicity and their potential use as a mercury contamination indicator in fish.

摘要

快速发展与水生环境中的汞污染有关，导致鱼类和其他水生生物中的汞中毒。由于分别以不同的持续时间剂量通过饮食或水接触的有机汞（甲基汞）和无机汞（氯化汞）的汞污染，在各种鱼类组织中均观察到组织病理学异常，如增生，炎症和坏死汞。知道组织的变化发生在每个器官的重要部位，这些部位在鱼类的正常生理行为中起着各种关键作用，因此了解鱼类如何应对汞污染以及这种重金属元素如何影响其总体健康至关重要。
