Sampling sites: locations and overall risk of toxic effects

The maps on this page show where our sampling sites were located in the estuaries. On each map sampling sites are represented by pie charts. These pie charts illustrate the overall risk of toxic effects on organisms at this site by indicating the percentage of trace elements and organic compounds measured at this site that fall into the categories:

low likelihood of toxic effects (green),
moderate likelihood of toxic effects (orange), and
high likelihood of toxic effects (red).
