这项研究调查了从阿拉伯海东北部小溪地区收集的六种鱼类的饮食组成和微塑料污染。结果表明,鱼的饮食主要由虾组成,藻类,鱼,浮游动物,微塑料占其饮食的4.83%(优势指数)。微塑料的平均丰度为每条鱼5.82至7.69种,它们的摄入受季节变化的影响,肠道丰满,和营养水平。微塑料污染对鱼种的条件因子和肝细胞指数没有显着影响。然而,聚合物危害指数表明,鱼中的微塑料污染与低到高的危险因素有关,这可能会通过食物链对水生生物和高等脊椎动物造成潜在危害。因此,这项研究强调需要立即关注和有效的法规,以减少微塑料污染,以保护海洋生物。
This
study investigated the diet composition and microplastic contamination in six fish species collected from the creek area of northeastern Arabian Sea. The results show that the diet of the fish is mainly composed of shrimps, algae, fish, and zooplankton, with microplastics constituting up to 4.83 % (Index of Preponderance) of their diet. The average abundance of microplastics ranges from 5.82 to 7.69 items per fish, and their ingestion is influenced by seasonal variation, gut fullness, and trophic level. Microplastic contamination has no significant effect on the condition factor and hepatosomatic index of the fish species. However, polymer hazard index indicates that microplastic pollution in fish is associated with a low to high risk factor, which might cause potential harm to aquatic lives and higher vertebrates via food chain. Therefore, this
study highlights the need for immediate attention and effective regulations to reduce microplastic pollution to protect marine life.
