Long-term monitoring of a mercury contaminated estuary (Ria de Aveiro, Portugal...
Coelho, J. P.; Pato, P.; Henriques, B.; Picado, A.; Lillebo, A. I.; Dias, J. M.; Duarte, A. C.; Pereira, M. E.; Pardal, M. A.The main aim of this research was to assess the mercury transport from an estuarine basin with a background of anthropogenic contamination during a spring tidal cycle (year 2009) and compare it with two previous tidal cycles (years 1994 and 1999), as part of a long-term monitoring program. Results showed that effective mercury transport occurs both in the dissolved and particulate fractions (0.18 and 0.20 kg pe...
Impact of mercury contamination on the population dynamics of Peringia ulvae (G...
Cardoso, P. G.; Sousa, E.; Matos, P.; Henriques, B.; Pereira, E.; Duarte, A. C.; Pardal, M. A.The effects of mercury contamination on the population structure and dynamics of the gastropod Peringia ulvae (also known as Hydrobia ulvae) and its impact on the trophic web were assessed along a mercury gradient in Ria de Aveiro (Portugal). The gastropod was revealed to be a tolerant species to the contaminant, since the highest densities, biomasses and growth productivity values were recorded at the intermed...
