Differential response in organs of the blue mussel Mytilus edulis exposed to microplastics at environmentally relevant concentrations

2018

AI summary

This study inventoried abandoned, lost, and discarded fishing gear (ALDFG) in Swedish coastal waters, mapping distribution and estimating volumes of ghost fishing equipment. Derelict gear was distributed across extensive seabed areas with particularly high densities in traditional fishing grounds.

Physiological impacts of microplastics on the Pacific oyster Crassostrea gigas: The role of particle size and concentration

AI summary Read the abstract

Laboratory experiments on Pacific oysters exposed to microplastics of varying sizes and concentrations found decreased survival rates, increased oxygen consumption, and histological damage to digestive and gill tissues, with effects scaling with concentration. Oysters are global seafood staples and efficient bioaccumulators, meaning physiological damage at environmentally relevant concentrations translates directly into concerns about both aquatic ecosystem health and the safety of oysters in the human diet.
