Widespread contamination of microplastics may lead to internalization in fish. This literature review from March 2019 to March 2020 details that a median of 60% of fish, belonging to 198 species captured in 24 countries, contain microplastics in their organs. Carnivores species ingested more microplastics than omnivores. Only 14% of fish were from aquaculture. Most studies focused on digestive systems, with presence in other organs currently being insufficiently assessed. Based on this assessment, knowledge gaps that should be addressed in future studies were identified.

全球鱼类对微塑料的污染：全球简要概述

微塑料的广泛污染可能导致鱼的内在化。该文献综述于2019年3月至2020年3月进行了详细介绍，其中有60％的鱼类（属于在24个国家中捕获的198种鱼类）的器官中含有微塑性物质。食肉动物比杂食动物摄入更多的微塑料。鱼中只有14％来自水产养殖。大多数研究集中在消化系统上，目前尚不足以评估其他器官中的存在。基于此评估，确定了未来研究中应解决的知识空白。
