英文摘要	Microplastics (<5 mm; MPs) are globally recognized as an issue of emerging concern in the marine environment. In this study, MPs were determined for the first time in sediments from Rías Baixas and Miño river shelf, to show the baseline contamination levels. The Rías is well known for its intense fishing and shellfish harvesting activities. The sampling stations were selected due to their different exposure to anthropogenic activities and/or pressures. Sediment samples were collected using a box corer dredge and analyzed with density separation and μF-TIR analysis to determine polymer type. The results showed MPs pollution in all stations. The mean concentration was 70.2 ± 74.2 particles/kg DW. The main MPs shape was fibers (88.8%) followed by fragments (5.80%). Regarding the polymers, the most abundant were PP (43%) and HDPE (29%). Once again, MPs are ubiquitous all along Rías and Miño river mouth as previously shown in different works. © 2020 Elsevier Ltd
