3.1.3.2. Bivalvia Bivalves include filter-feeding oysters, mussels, and clams. These organisms have been used as bioindicators to determine aquatic pollution due to their sensitivity to biotic and abiotic changes. Therefore, the sensitivity of bivalves to MPs has also been of interest and extensively studied.

Die kleineren Asymmetrien sind meist die Folge davon, das die eine Schalenklappe schlosartig in der anderen ...
