| parasites and symbionts from mytilus galloprovincialis (lamark, 1819) (bivalves: mytilidae) of the aveiro estuary portugal. | the primary aim of the present study was to conduct a 1-yr parasitological survey of a mytilus galloprovincialis mussel population from the aveiro estuary, portugal. in addition, we attempted to assess the host response to parasites by examining host histopathology, including an evaluation of hemocyte infiltration and parasite encapsulation. the parasites present (prevalence) included the following: 1 protozoan, nematopsis sp. (70%); 1 turbellarian, urastoma cyprinae, (39%); 2 trematodes, diphth ... | 2010 | 19785477 |
| integrative assessment of organotin contamination in a southern european estuarine system (ria de aveiro, nw portugal): tracking temporal trends in order to evaluate the effectiveness of the eu ban. | organotin (ot) compounds have been used as biocide agents in antifouling paints since the mid 1960s and are now ubiquitous in the marine environment. due to their high toxicity to non-target species they were banned from antifouling paints in the european union in 2003 (2002/62/ec directive). the aim of the present work is to assess any obvious decline of the ot environmental levels at ria de aveiro (nw portugal) after the ban. the organotins - monobutyltin (mbt), dibutyltin (dbt), tributyltin ( ... | 2007 | 17727897 |
