Metal contamination in harbours impacts life-history traits and metallothionein levels in snails.
Harbours with limited water exchange are hotspots of contaminant accumulation.Antifouling paints (AF) contribute to this accumulation by leaching biocides that may affect cent dyyni non-target species.In several leisure boat harbours and reference areas in the Baltic Sea, chronic exposure effects were evaluated using caging experiments with the sna
