Hydrobia ulvae imposex levels at Ria de Aveiro (NW Portugal) between 1998 and 2...
Galante-Oliveira, S.; Oliveira, I.; Pacheco, M.; Barroso, C. M.Imposex expression in prosobranch gastropods has been widely used as a biomarker of tributyltin (TBT) pollution. Estuaries have been described as the most affected areas by this problem since they usually enclose the main TBT sources—ports, dockyards and marinas—resulting from the compound’s application as a biocide in antifouling paints on ships. Using Hydrobia ulvae as a bioindicator, the current work address...
Imposex levels and tributyltin pollution in Ria de Aveiro (NW Portugal) between...
Galante-Oliveira, S.; Oliveira, I.; Jonkers, N.; Langston, W. J.; Pacheco, M.; Barroso, C. M.Nucella lapillus imposex levels and organotin (OT) concentrations in water and female tissues were measured in samples collected from the Ria de Aveiro (NW Portugal) between 1997 and 2007. Vas deferens sequence index (VDSI), relative penis size index (RPSI), mean female penis length (FPL) and percentage of imposex affected females (%I) were used to determine imposex levels at each site. A significant temporal d...
Can Nassarius reticulatus be used as a bioindicator for Hg contamination? Resul...
Coelho, J. P.; Pimenta, J.; Gomes, R.; Barroso, C. M.; Pereira, M. E.; Pardal, M. A.; Duarte, A.The focus of this work is to explore the use of the netted whelk, Nassarius reticulatus (L.), as an indicator of mercury (Hg) contamination, by assessing the concentration of Hg in the sediments and in the whelk along the entire Portuguese coast. Total Hg concentrations ranged from below the detection limit (0.01 ng absolute mercury) up to 0.87 mg kg-1 dry weight (dwt) in sediments and between 0.06 and 1.02Â...
