Persistent Organic Pollutants (POPs) in plastic pellets from Las Canteras Beach (Canary Islands)

Abstract

Stranded pellets have been collected from Las Canteras beach, Gran Canaria, to analize the corresponding UV filters (289.12 ng/g pellet), chlorpyrifos (4.72 ng/g pellet), OCPs (99.18 ng/g pellet), BDEs (0.89 ng/g pellet), OPFRs (27.09 ng/g pellet), PAHs (271.96 ng/g pellet) and PCBs (28.22 ng/g pellet) associated to these microplastics and try to determine their main sources. Of the total of 77 pollutants analyzed, only 52 compounds have appeared in the coastal zone. Most of the sources are of exogenous origin, adsorbed to the pellet during their residence on the sea surface, with the exception of UV filters, chlorpyrifos, PAHs and PCBs that are possibly related to tourism and the industrial activity of the zone.

Se han recogido pellets en la arena de la playa de Las Canteras, Gran Canaria, para analizar los filtros UV (289.12 ng/g pellet), chlorpyrifos (4.72 ng/g pellet), OCPs (99.18 ng/g pellet), BDEs (0.89 ng/g pellet), OPFRs (27.09 ng/g pellet), PAHs (271.96 ng/g pellet) y PCBs (28.22 ng/g pellet) asociados a estos microplásticos y tratar de determinar sus principales fuentes. Del total de 77 contaminantes analizados han aparecido 52 compuestos en la zona costera. La mayoría de las fuentes son de procedencia exógena, adsorbidos a la superficie del pellet durante su estancia en la superficie del mar, a excepción de los filtros UV, chlorpyrifos, PAHs y PCBs que posiblemente estén relacionados con el turismo y la actividad industrial de la zona.
