The measurement of 131I-labeled microplastic accumulation in dog conch (Laevistrombus canarium) using radiotracing method
AI summary Read the abstract
Researchers used iodine-131-labeled polystyrene microplastics as a radiotracer to measure bioaccumulation in dog conch (Laevistrombus canarium), finding that optimal accumulation occurred at a salinity of 32 g/L and the lowest microplastic concentration tested, demonstrating that environmental salinity significantly influences microplastic uptake in marine mollusks.
This study aims to evaluate the bioaccumulation of microplastics in dog conch (Laevistrombus canarium) using polystyrene microplastics labeled with Iodine-131 as a radiotracer with variations in water salinity (30, 32, and 34 g L−1) and microplastic concentrations (0.9625, 1.925, and 3.85 m g L−1). The results showed that optimal bioaccumulation occurred at a salinity of 32 g L−1 and the lowest microplastic concentration, indicating physiological limitations in the accumulation process. The radiotracer method proved effective in sensitively and real-time detecting microplastic accumulation. These findings highlight the importance of environmental parameters on microplastic bioaccumulation and their implications for the health of marine organisms.

Microplastics: Transfer Pathways, Radiotracing and Challenges for Coastal Environments
AI summary Read the abstract
This review maps how wastewater, industrial discharge, and plastic degradation funnel microplastics into rivers, estuaries, and coastal lagoons, and explores how radiotracing techniques can follow these particles through the environment. Coastal semi-enclosed systems are especially vulnerable accumulation points, making them critical targets for both monitoring and pollution control efforts.
Determining microplastics bioaccumulation in Babylonia spirata adopting nuclear analysis technique
AI summary Read the abstract
Scientists used a radioactive tracking method to see how much microplastic builds up in a type of sea snail, finding that the snails absorbed more of it depending on the saltiness of the water and how much microplastic was around. This matters because these snails are eaten by other animals (and sometimes people), meaning microplastics could be working their way up the food chain into our seafood.
Temporal Bioindication of Microplastics by the Asian Clam, C. Fluminea
AI summary Read the abstract
Monthly sampling of Asian clams over seven months revealed that 84% of specimens contained microplastics, with concentrations inversely correlated with stream discharge, suggesting clams reflect microplastic storage during dry periods and export during floods. These results support the Asian clam as a useful temporal bioindicator for microplastic pollution, offering a biological monitoring tool that captures seasonal variability in contamination levels.
