数百种野生动物中普遍存在人为碎片，以及与之相关的化学物质的毒性，已经开始引起人们对海鲜中人为碎片存在的担忧。我们评估了供人类食用的鱼类和贝类中是否存在人为碎片。我们从印度尼西亚望加锡和美国加利福尼亚州的市场进行了采样。尽可能对所有鱼类和贝类进行物种鉴定。使用 10% KOH 溶液从鱼类和整个贝类的消化道中提取人为碎片，并在解剖显微镜下进行定量。在印度尼西亚，28% 的个体鱼类和 55% 的所有物种中都发现了人为碎片。同样，在美国，25% 的个体鱼类和 67% 的所有物种中都发现了人为碎片。 33% 的贝类样本中还发现了人为碎片。从印度尼西亚的鱼中回收的所有人为碎片都是塑料，而从美国的鱼中回收的人为碎片主要是纤维。碎片类型的差异可能反映了国家之间不同的来源和废物管理策略。我们报告了直接出售供人类食用的鱼类中塑料碎片的一些初步发现，引起了对人类健康的担忧。
The ubiquity of anthropogenic debris in hundreds of species of wildlife and the toxicity of chemicals associated with it has begun to raise concerns regarding the presence of anthropogenic debris in seafood. We assessed the presence of anthropogenic debris in fishes and shellfish on sale for human consumption. We sampled from markets in Makassar, Indonesia, and from California, USA. All fish and shellfish were identified to species where possible. Anthropogenic debris was extracted from the digestive tracts of fish and whole shellfish using a 10% KOH solution and quantified under a dissecting microscope. In Indonesia, anthropogenic debris was found in 28% of individual fish and in 55% of all species. Similarly, in the USA, anthropogenic debris was found in 25% of individual fish and in 67% of all species. Anthropogenic debris was also found in 33% of individual shellfish sampled. All of the anthropogenic debris recovered from fish in Indonesia was plastic, whereas anthropogenic debris recovered from fish in the USA was primarily fibers. Variations in debris types likely reflect different sources and waste management strategies between countries. We report some of the first findings of plastic debris in fishes directly sold for human consumption raising concerns regarding human health.
