Summary

Researchers found that microplastic ingestion by the clam Atactodea striata reduced clearance rate — and therefore energy intake — particularly at high concentrations, while respiration rate and absorption efficiency remained unchanged, with pseudofaeces and depuration limiting the amount of plastic retained in body tissue.

The effects of microplastic concentrations (10itemsl and 1000itemsl) on the physiological responses of Atactodea striata (clearance rate, absorption efficiency, respiration rate) were investigated. The fates of ingested microplastics and the efficiency of depuration in removing ingested microplastics were also studied. A. striata ingested microplastics and the clearance rate was reduced at high concentration of microplastics. Since the respiration rate and absorption efficiency remained unchanged in exposed A. striata, reduction in the clearance rate would reduce the energy intake. Ingestion and retention of microplastics in the body were further limited by the production of pseudofaeces and faeces, and depuration in clean water, resulting in a very small amount of microplastics stored in the body of the clam.
