Data on the occurrence and abundance of meso and microplastics for the South Pacific are limited and there is urgent need to fill this knowledge gap. The main aim of the study was to apply a rapid screening method, based on the fluorescence tagging of polymers using Nile red, to determine the concentration of meso and microplastics in biota, sediment and surface waters near the capital cities of Vanuatu and Solomon Islands. A spatial investigation was carried out for sediment, biota and water as well as a temporal assessment for sediment for two consecutive years (2017 and 2018). Accumulation zones for microplastics were identified supported by previous hydrodynamic models. Microplastics were detected for all environmental compartments investigated indicating their widespread presence for Vanuatu and Solomons Islands. This method was in alignment with previous recommendations that the Nile red method is a promising approach for the largescale mapping of microplastics in a monitoring context.

关于南太平洋中空和微塑料的发生和丰富的数据是有限的，迫切需要填补这一知识空白。该研究的主要目的是应用一种快速筛选方法，该方法基于使用尼罗红对聚合物进行荧光标记的方法，以确定内消旋体的浓度。瓦努阿图和所罗门群岛首府附近的生物区系，沉积物和地表水中的微塑料。连续两年（2017年和2018年）对沉积物，生物群和水进行了空间调查，并对沉积物进行了时间评估。先前的水动力模型支持了微塑料的聚集区。在所调查的所有环境小室中都检测到了微塑料，这表明它们在瓦努阿图和所罗门群岛中普遍存在。该方法与以前的建议一致，即尼罗红法是在监测环境中大规模绘制微塑料的一种有前途的方法。
