This is the first regional, multi-annual assessment of floating microplastics in Scotland's seas. Sea surface samples were collected from 2014 to 2020, using a catamaran swimmer body/neuston net trawl and evaluated for the presence of microplastics. Microplastics were present in the surface waters of all Scottish Marine Regions (SMR) and Offshore Marine Regions (OMR) though almost 35% of sample sites contained no microplastics. Concentrations ranged from 0 to 91,128 microplastics km sea surface. Potential hotspots were identified in the Clyde (0-77,168 microplastics km), Forth & Tay (0-83,729 microplastics km) and the Solway (607-91,128 microplastics km). Fragmented plastics accounted for almost 50% of the microplastics recovered and this may suggest that the microplastics in Scotland's seas are predominantly from the breakdown of larger items. Due to the variable geographic and temporal extents of the data it was not possible to carry out a trend assessment.
这是苏格兰海域首次对漂浮微塑料进行的区域性、多年度评估。从 2014 年到 2020 年，使用双体船游泳者身体/海面浮游生物网拖网收集了海面样本，并评估了微塑料的存在情况。所有苏格兰海洋区域（SMR）和近海海洋区域（OMR）的海面水中都存在微塑料，但近 35%的采样点没有微塑料。浓度范围从 0 到 91128 个微塑料/km 海面。在克莱德（0-77168 个微塑料/km）、福斯和泰河（0-83729 个微塑料/km）和索尔威（607-91128 个微塑料/km）地区确定了潜在的热点。回收的微塑料中近 50%是碎片塑料，这可能表明苏格兰海域的微塑料主要来自较大物品的分解。由于数据的地理和时间范围不同，因此无法进行趋势评估。
