Article Synopsis
- Plastic pollution significantly impacts marine ecosystems, with microplastics entering the food chain through invertebrates and fish.
- The study examined the diets of six fish species to determine how their feeding behaviors contribute to plastic ingestion, classifying them into various predator groups based on age and trophic interactions.
- Results showed that fish with higher dietary overlap consumed more microplastic fibers, indicating that a broader diet may increase vulnerability to plastic ingestion, highlighting the need to understand ecological interactions to address plastic contamination effectively.
With the objective of characterizing the composition and spatial distribution of plastic fragments in a subtropical lagoon system, five sample areas affected by various anthropogenic impacts were chosen in the southern part of the Estuarine Lagoon System in Laguna, Santa Catarina, Brazil. The total density of the floating meso- and microplastics encountered was 7.32/m, with the greatest density in the access channel and external area of the lagoon.

MPs were sampled monthly, and the abundance and size were determined for hard solids, soft plastic, plastic filaments, and paint fragments. Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) analysis was performed, and the MPs were classified as polyethylene, polyester, polypropylene, polybutadiene, and polystyrene.
