摘  要:研究发现,水产养殖水域中微塑料的丰度与经济条件、流体动力学条件、人口密度等因素密切相关。微塑料在鱼体内的累积顺序为消化道、鳃>肝脏、脑>肌肉。肠道、鳃和肝脏中微塑料的主要存在形式分别为纤维、碎片和颗粒。具有吞咽摄食行为的鱼类体内微塑料的丰度高于滤食性鱼类,杂食性鱼类体内微塑料的丰度高于草食性/肉食性鱼类,底栖鱼类体内微塑料的丰度高于中上层鱼类。此外,本文对水产养殖领域微塑料研究的未来方向进行了展望,以期为评估微塑料对水产品质量安全的影响提供参考。Studies have found that the concentration of microplastics in aquaculture areas is closely related to factors such as economic conditions,fluid dynamics,and population density.The accumulation of microplastics in fish follows this order:digestive tract,gills>liver,brain>muscle.The primary forms of microplastics in the intestine,gills,and liver are fibers,fragments,and fine particles.Fish with a swallowing feeding behavior have higher microplastic concentrations than filter-feeding species,omnivorous fish accumulate more than herbivorous/carnivorous fish,and benthic fish have higher microplastic levels compared to pelagic fish.The study provides insights into the future of microplastic research in aquaculture.
