Summary

This study examined microplastic distribution across nine different tissue types in the Zhikong scallop and in the surrounding seawater from three coastal aquaculture areas, finding microplastics in digestive glands, gills, and mantles. The broad tissue distribution of microplastics in edible scallops means that simply removing digestive organs before consumption does not fully eliminate human microplastic exposure.

Study Type Environmental

Microplastics have adverse effects on marine organisms. However, there are limited data on microplastics distribution patterns in various tissues of marine organisms. Microplastics in seawater and nine types of tissues of the Zhikong scallop (Chlamys farreri) from three coastal aquaculture areas were analysed. The results showed that in seawater, microplastics were mainly fibrous. There were no significant differences in microplastics abundance among the three areas. The concentrations of microplastics in the scallop anus, intestinal tract and kidney were substantially higher than those in the other tissues. Microplastics abundance ranged from 8 to 13 particles per scallop. Microplastics colours were mainly black, transparent and blue, and there were no significant tissue distribution patterns. Microplastics size ranged from 5 μm to 1 mm. The microplastics abundance in the haemolymph was significantly correlated with those of the surrounding seawater. Additional study is necessary to determine the toxic effects of microplastics on marine organisms.
