Overview

Analysis reveals microplastic contamination in sediments affects ecological risks in coastal ecosystems, suggesting urgent regulatory needs.

Key Points

  • Microplastic contamination ranges from 9.17 to 12.17 microplastics per kilogram of sediment.
  • Polyethylene terephthalate was identified as the most abundant polymer present in the lagoon sediments.
  • Morphological analysis showed that fibers and black microplastics were the most prevalent types collected.
  • The Polymer Risk Index indicated that the ecological risks predominantly fall into high and very high categories.
