Shape-wise distribution of microplastics in Indus River dolphins in this study.

AI summary Read the abstract

Researchers documented the shape-wise distribution of microplastics recovered from Indus River dolphins (Platanista minor), finding fibers to be the most prevalent morphology among MPs detected in the gastrointestinal tracts of five stranded individuals. The data provide supplementary characterisation of plastic particle types accumulating in this critically endangered freshwater cetacean.

Compartment-wise distribution of microplastics from Indus River dolphins.

AI summary Read the abstract

Researchers analysed the compartment-wise distribution of microplastics across anatomical regions of Indus River dolphins (Platanista minor), finding MPs throughout the complete gastrointestinal tract of five stranded individuals with an average of 286.4 MPs per individual. The distribution data illuminate the pathways of MP accumulation via prey consumption and incidental ingestion in this endangered species.

First characterization and risk assessment of microplastics in the endangered Indus River dolphin (Platanista minor): Implications for conservation strategies

AI summary Read the abstract

Researchers found microplastics in the complete gastrointestinal tracts of five endangered Indus River dolphins (Platanista minor) stranded between 2019 and 2022, with an average of 286 MPs per individual, predominantly fiber-shaped PET particles. Polymer risk assessment revealed medium to high ecological risk levels, representing the first baseline data on MP pollution in this critically endangered freshwater cetacean.

Ecological risk assessment of MP polymers.

AI summary Read the abstract

Researchers performed an ecological risk assessment of microplastic polymers identified in the gastrointestinal tracts of five Indus River dolphins (Platanista minor), evaluating the hazard posed by the polymer types and concentrations detected. The assessment contributes to understanding the ecological implications of MP accumulation in this critically endangered freshwater cetacean.

Color-wise distribution of MPs in this study.

AI summary Read the abstract

Researchers characterised the color distribution of microplastics found in the gastrointestinal tracts of five endangered Indus River dolphins (Platanista minor) stranded along the Indus River between 2019 and 2022. The color-wise breakdown supplements broader findings showing an average of 286 MPs per individual, with particle properties suggesting accumulation through both prey consumption and incidental ingestion.

Microplastic load and distribution in the respiratory and digestive systems of some commercial fish species in the southwestern coast of Bangladesh

AI summary Read the abstract

This Bangladeshi study investigated microplastic occurrence in the respiratory and digestive systems of three commercially important fish species from the southwestern coast. MPs were found in all species, with the digestive tract accumulating more particles than the gills, and fiber was the dominant particle shape detected.
