| integrative assessment of marine pollution in galician estuaries using sediment chemistry, mussel bioaccumulation, and embryo-larval toxicity bioassays. | an integrative assessment of environmental quality was carried out in selected sites along the galician coast (nw iberian peninsula) combining analytical chemistry of seawater and sediments, bioaccumulation in the marine mussel, and embryo-larval sediment toxicity bioassays, in order to link biological and chemical criteria for the assessment of coastal pollution. maximum values of hg and cu in seawater, sediment and mussels, were found in the inner part of ria of pontevedra, while maximum level ... | 2003 | 12821002 |
| assessment of coastal marine pollution in galicia (nw iberian peninsula); metal concentrations in seawater, sediments and mussels (mytilus galloprovincialis) versus embryo-larval bioassays using paracentrotus lividus and ciona intestinalis. | sediments from three galician rias were tested for toxicity using sea-urchin and ascidian sediment elutriate embryo-larval bioassays. trace metal contents in seawater, sediments and mussels were also determined and subjected to multidimensional scaling methods which grouped stations according to chemical contamination. high metal contents were found in seawater, sediments and mussels from the ria of pontevedra, and moderate levels were detected in the ria of vigo and ria of arousa. the results r ... | 2003 | 12860437 |
| integrative assessment of coastal pollution in a ría coastal system (galicia, nw spain): correspondence between sediment chemistry and toxicity. | elutriate embryo-larval bioassays with sea-urchins (paracentrotus lividus) and ascidians (ciona intestinalis) were conducted concurrently with trace metal analyses as part of an integrative assessment of sediment pollution at ría de pontevedra (galicia, nw spain). high metal contents in sediments were found in localised areas from the inner part of the estuary indicating a clear anthropogenic influence. in particular, very high cu, zn and pb levels were found at sites p2 and p3, which were also ... | 2008 | 18377949 |
