| accumulation trends of petroleum hydrocarbons in commercial shellfish from the galician coast (nw spain) affected by the prestige oil spill. | aliphatic and aromatic hydrocarbons were determined in three species of commercial shellfish, namely razor shells (ensis arcuatus and ensis siliqua), goose barnacle (pollicipes cornucopia) and sea urchin (paracentrotus lividus), living in different habitats and exhibiting different feeding behaviors. the samples were collected monthly, from january 2003 to october 2004, in three stations of the galicia coast (nw spain), following the prestige oil spill, with the aim of assessing their response t ... | 2009 | 19150729 |
| 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 |
| 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 |
