In this study, we investigated the concentration, distribution, and characteristics of neustonic MPs in the Canary Islands, with a particular focus on the island leeward zones, where a high accumulation of floating marine microplastics is expected. Samples were collected with a manta net at 15 different sites from Alegranza to La Gomera during the IMPLAMAC expedition. The microplastic concentration in surface waters ranged from 0.27 MPs/m in Alegranza to 136.7 MPs/m in the south of Gran Canaria. The highest concentration of MPs found was due to the presence of a sea-surface slick, also called "marine litter windrow", formed in the south of Gran Canaria. The most abundant zooplankton group in the neuston was copepods, except at the marine litter windrow where fish larvae and eggs predominated. This indicates that coastal areas where marine litter windrows are formed have a high risk of MP ingestion and potential adverse effects on biota.
在这项研究中，我们调查了加那利群岛中性浮游微塑料的浓度、分布和特征，特别关注预期有大量漂浮海洋微塑料积累的岛屿背风区。IMP LAMAC 考察期间，在阿莱格兰萨至拉戈梅拉的 15 个不同地点使用蝠鲼网采集了样本。表层水中微塑料的浓度范围从阿莱格兰萨的 0.27 MPs/m 到加那利群岛南部的 136.7 MPs/m。在加那利群岛南部发现的最高浓度的微塑料是由于海表油膜（也称为“海洋垃圾风排”）的存在所致。在中性浮游生物中，最丰富的浮游动物群是桡足类，而在海洋垃圾风排处，鱼类幼体和卵则占主导地位。这表明形成海洋垃圾风排的沿海地区存在微塑料摄入的高风险，并且可能对生物群产生潜在的不利影响。
