Occurrence of marine plastic litter and plasticizers from touristic beaches of Arauco Gulf in Central Chile

Popis výsledku v původním jazyce

Marine plastic litter (MPL) was collected from beaches (n = 3) of the Arauco Gulf in central Chile in spring 2021 and summer 2022. MPL was analyzed for physical and chemical characteristics, and plasticizers were also screened using FTIR-ATR. Three hundred seventeen plastic items with an accumulated weight of 226.8 g were found. MPL densities ranged from 0.4 to 17.1 items m(-2). Significant differences (p &lt; 0.05) between seasons were observed for Arauco and Maule beaches, being similar to ten times higher in summer compared to spring. Solid pieces were the predominant shape, macroplastics were the most abundant (&gt;2.5 cm), and white and blue colors were dominant. Polypropylene (52 %) and polyethylene (31 %) were the predominant polymers. Plasticizers (n = 3) were detected in the MPL in the study area (dioctyl phthalate, polybutene, and alpha-methylstyrene) for the first time. This study contributes new information related to MPL in coastal areas of central Chile and their chemical composition.
