为了为风险评估提供信息，需要可靠、省时和负担得起的量化方法，以便在世界海洋中建立微塑料污染基线。为了实现这一目标，研究人员对英国大陆架三个不同区域的沉积物进行了MP丰度调查：琼斯海岸的西北部、凯尔特海的峡谷和北海的道格尔海岸，利用尼罗河红标记方法来评估其时间效率和成本。顶部10 cm的平均MP丰度为1050-2700 MP kg-1。MP丰度随沉积物深度的增加而降低，随水深的增加而增加。研究结果强调了空气污染的程度，并说明了尼罗红以相对较低的成本进行大比例尺制图的价值。
To inform risk assessments, reliable, time efficient and affordable quantification methods are required for creating a microplastic (MP) pollution baseline in the world's oceans. To facilitate this, MP abundance was investigated in sediments of three contrasting areas of the UK continental shelf: North West of Jones Bank, the Canyons in the Celtic Sea and Dogger Bank in the North Sea, utilising the Nile Red tagging method to assess its time efficiency and cost. Average MP abundance in the top 10 cm was 1050-2700 MP kg-1. MP abundance decreased with increasing sediment depth and increased with increasing water depth. The findings emphasise the extent of MP pollution and illustrate the value of Nile Red for large scale mapping at relatively low cost.
