Occurrence of perfluoroalkyl substances (PFASs) in marine plastic litter from coastal areas of Central Chile

Popis výsledku v původním jazyce

Perfluorinated alkyl substances (PFASs) were determined in marine plastic litter (MPL) on six beaches of central Chile. MPL was characterized physically and chemically, showing an abundance of macroplastic (size &gt;2.5 cm). The polypropylene (PP) (47%) was the predominant polymer found. The Desembocadura beach, located at the mouth of the Biobio River, recorded the highest abundance of MPL (3.7 items m−2). PFAS detected (n = 15/21) ranged from 279 to 1211 pg g−1 and accounted for MeFOSE (46%) &gt; PFHxS (14%) &gt; PFPA (11%) &gt; PFBS (6%) &gt; PFOA (4%) and &gt; PFOS (4%). Long-chain PFAS were prevalent, which can be metabolically degraded into PFOS (new POPs). This study i) highlights the need to further investigate the occurrence of chemicals in the MPL to reduce their impact on the environment; and ii) points out the need to improve future coastal management strategies for the elimination of solid waste along the coast of the country.
