Distribution patterns of microplastics in various tissues of the Zhikong scallop (Chlamys farreri) and in the surrounding culture seawater
AI summary Read the abstract
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.
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.

Uptake, Whole-Body Distribution, and Depuration of Nanoplastics by the Scallop Pecten maximus at Environmentally Realistic Concentrations
AI summary Read the abstract
Researchers used radiolabeled nanoplastics at environmentally realistic concentrations to track uptake in scallops and found the particles distributed throughout the body, including the intestine, kidney, gills, and muscle. After transfer to clean water, scallops retained a significant fraction of nanoplastics for weeks, indicating slow depuration rates even at low exposure levels.
Microplastics in four bivalve species and basis for using bivalves as bioindicators of microplastic pollution
AI summary Read the abstract
Researchers found microplastics in 80% of shellfish samples (scallops, mussels, oysters, and clams) collected across four seasons in Qingdao, China. PVC and rayon fibers were the most common plastic types, with different shellfish species accumulating different sizes and types of particles. Since these shellfish are commonly eaten by people, the findings highlight a direct route for microplastics to enter the human diet through seafood.
Assessment of Microplastics Contamination in Commericial Clams in the Coastal Zone of Vietnam

Microplastic contamination was assessed in commercially harvested clams from aquaculture farms in coastal Vietnam, a country where microplastic impacts on aquaculture are poorly understood. Both vertebrates and invertebrates in coastal areas were found to ingest microplastics, raising concerns about food safety in Vietnamese seafood.
