Abstract (EN): \Imposex in the gastropod Hinia reticulata, a bioindicator for tributyltin (TBT) contamination, was investigated in locations at different distances from the Oporto harbour-dredged material discharge site. The degree of imposex found was inversely related to the distance to the discharge site, the highest imposex frequency being found closest to the discharge area. However, the levels of imposex found were low when compared with those reported for H. reticulata populations from moderately TBT-contaminated areas. Despite detectable levels of dibutyltin (DBT) and nnonobutyltin (MBT) in snail tissues (total butyltins ranging from 84 to 4 10 ng/g Sri dry wt.), TBT was below detection limit in all snail samples collected in open sea.
