通过测量北太平洋中央大气高压单元下表层水中中微塑料和浮游动物的相对丰度和质量，评估了公海滤食性动物摄入塑料颗粒的潜力。 Neuston 样本是使用内衬 333 u 网眼的蝠鲼拖网在随机地点收集的。中子塑料的丰度和质量是太平洋地区有记录以来最大的，分别为 334271 件 km(2) 和 5114 g km(2)。浮游生物的丰度大约是塑料的五倍，但塑料的质量大约是浮游生物的六倍。最常取样的可识别塑料类型是薄膜、聚丙烯/单丝线和不明塑料，其中大部分是杂项碎片。这三类合计占塑料件总数的98%。 (C) 2001 Elsevier Science Ltd. 保留所有权利。
The potential for ingestion of plastic particles by open ocean filter feeders was assessed by measuring the relative abundance and mass of neustonic plastic and zooplankton in surface waters under the central atmospheric high-pressure cells of the North Pacific Ocean. Neuston samples were collected at I I random sites, using a manta trawl lined with 333 u mesh. The abundance and mass of neustonic plastic was the largest recorded anywhere in the Pacific Ocean at 334271 pieces km(2) and 5114 g km(2), respectively. Plankton abundance was approximately five times higher than that of plastic, but the mass of plastic was approximately six times that of plankton. The most frequently sampled types of identifiable plastic were thin films, polypropylene/monofilament line and unidentified plastic, most of which were miscellaneous fragments. Cumulatively, these three types accounted for 98% of the total number of plastic pieces. (C) 2001 Elsevier Science Ltd. All rights reserved.
