This web page is the point of public access to spatial data infrastructure (SDI) of the Group of Ecotoxicology of the University of Vigo, in the public information that is related to the pollution developed and compiled by the group, mainly in the coasts of Galicia, although not exclusively. The information is available for your visualization, query, and download via the web or using any GIS desktop.
The available data will grow as you go by incorporating new information to the databases of the group.
See and interact with data published by the group in a viewer via the web on the orthophoto PNOA (2007-2008), the OpenStreetMap layer or Google image Satellite.
- Access the metadata catalog based in Geonetwork to search for the information published by the group.
- Add external mapping services (WMS) of other administrations or producers of digital mapping.
- Access to group data through GIS software through WMS and WFS standards.
- Download the digital mapping in various vector formats (GML, KML and Shapefile).
Map Viewer
The cartographic viewer provides information about the chemical quality status of the Galician coastal water (mainly), based on chemical pollutants and ecotoxicity bioassays data. The data comes from two sources: literature and unpublished data collected by the group.
The chemical quality status is represented by a traffic light color code, similar to the one used by the OSPAR Commission in its Quality Status Report, for what they propose as cut-off points to separate the different environmental states as a function of concentrations or response metrics. It has been used three boundary values or cutoff points (P1, P2 and P3) which leads to four ecological states: background, acceptable, uncertain and unacceptable.
The cutoff points are established taking into account the criteria of the OSPAR Commission and scientific studies widely accepted by the scientific community and supranational organizations, selecting the most appropriate for each type of chemical contaminant and for each ecotoxicological response.
Chemical pollution data currently available is: concentrations of metals and polycyclic aromatic hydrocarbons (PAHs) in sediments (cutoff points in table 1 and table 2) and wild mussels (cutoff points table 4 and table 5), and ecotoxicity bioassays (PNR values) using sea-urchin larvae exposed to water and elutriates (aqueous extraction of the sediment) (cutoff points in table 3).
Data is grouped in five-year periods, given the stability of the sediment, yielding three study periods: 1997-2001, 2002-2006 and 2007-2011, selecting the worst state for the same station when more than one value is available.
