Ria de Aveiro (Portugal) is a shallow coastal lagoon of high economic and ecological importance. Hardly any data on its chemical pollution by polar organic pollutants are available in literature. This study focused the presence sources series phenolic endocrine-disrupting compounds (EDCs) this area, including parabens, alkylphenolic bisphenol-A (BPA). A number possible present large harbours lagoon, city rivers discharging into area. recently constructed submarine wastewater outfall, located...
Anthropogenic endocrine disruptors now contaminate all environments globally, with concomitant deleterious effects across diverse taxa. While most studies on disruption (ED) have focused vertebrates, the superimposition of male sexual characteristics in female dogwhelk, Nucella lapillus (imposex), caused by organotins, provides one clearcut ecological examples anthropogenically induced ED aquatic ecosystems. To identify underpinning mechanisms imposex for this 'nonmodel' species, we combined...

Abstract Nucella lapillus imposex—superimposition of male characters onto prosobranch (a subclass gastropod molluscs) females—and organotin female body burden were surveyed on the Portuguese coast, from Vila Praia de Âncora (northern limit) to da Luz (southern limit), at 17 sampling stations, between May and August 2003. The vas deferens sequence index (VDSI), relative penis size (RPSI), percentage females affected with imposex (% I ) sterile S used assess level each site. VDSI, RPSI %...
Abstract Nassarius reticulatus (whelk) imposex levels and organotin body burden (b.b.) were surveyed along the Portuguese coast, from Vila Praia de Âncora (northern limit) to Lagos (southern limit), between May August 2003. The percentage of females affected with (%I), relative penis length index (RPLI), vas deferens sequence (VDSI) degree female oviduct convolution (AOS) used assess level at each site. These indices determined for 23 sampling stations throughout coast in range 0.0–100%,...
Nucella lapillus (dog whelk) imposex levels were assessed along the mainland Portuguese coast in 2006 and 2008 compared with available data from 2003 for same area. Given that specimen size has been described as a factor inducing variation some of assessment indices, thus resulting less reliable results, new monitoring analysis procedures are applied to study change 2008. A significant decline intensity was observed area during period, ecological status (under terms defined by OSPAR...
Adult Nassarius reticulatus were exposed for two to three months dissolved tributyltin (TBT), dibutyltin (DBT), triphenyltin (TPT) and diphenyltin (DPT) chlorides copper sulphate (CuSO 4 ) in order study the effectiveness of these compounds induce imposex (penis vas deferens development). The dialkyltins did not promote under exposure 500 ng Sn l −1 Cu . However, nominal concentrations varying between 100 TBT or TPT induced in, respectively, 22 43% 24 44% females. testosterone titres females...
Nucella lapillus imposex and organotin tissue contamination were assessed, during 2006, at twenty sites in North Wales, between Anglesey Shell Island on the Lleyn Peninsula.
