Imposex: History, Research & Standards

Imposex is a disorder observed in certain marine and freshwater gastropod mollusks, where female individuals develop male sexual characteristics, such as a penis and vas deferens, due to exposure to specific environmental pollutants. This condition is primarily induced by organotin compounds, notably tributyltin (TBT), which have been widely used in…
