Pollutant-ban has made snails healthy again

Sammendrag

The environmental pollutant TBT can mimic hormones to the extent that it sterilizes female snails and make them grow non-functional penises and vas deferens. But for the first time since monitoring started up in 1991 and the total ban of TBT entered force in 2008, only fertile dogwhelk have been found along the Norwegian coastline.
