为了调查日本周围东亚海域浮游微生物（5毫米）的浓度，2014年夏季使用两艘船同时进行了实地调查。总颗粒数（千公里-2）是根据使用neuston网收集的小塑料碎片（微塑料和中塑料）的观测浓度（千米-3）计算的。研究区域内的微塑料颗粒总数为1，720，000件km（-2），是北太平洋的16倍，是世界海洋的27倍。中塑料的比例增加的东北向洋流的上游，这样的小塑料碎片在本调查中收集被认为是来自黄海和东海西南的研究区。(C)2015年，作者。爱思唯尔有限公司出版
To investigate concentrations of pelagic micro- (5 mm) in the East Asian seas around Japan, field surveys using two vessels were conducted concurrently in summer 2014. The total particle count (pieces km(-2)) was computed based on observed concentrations (pieces m(-3)) of small plastic fragments (both micro- and mesoplastics) collected using neuston nets. The total particle count of microplastics within the study area was 1,720,000 pieces km(-2), 16 times greater than in the North Pacific and 27 times greater than in the world oceans. The proportion of mesoplastics increased upstream of the northeastward ocean currents, such that the small plastic fragments collected in the present surveys were considered to have originated in the Yellow Sea and East China Sea southwest of the study area.
