The task group on supporting physico-chemical elements has reviewed information reported by Member States to WISE on the standards for general physico‐chemical quality elements, including nutrients. A wide range of supporting physico-chemical elements are used by Member States. This report provides a general introduction and then focusses on those elements that are ecologically most relevant for transitional and coastal waters and which are used by enough Member States to make realistic comparisons. These are:
- Transitional waters: Transparency, dissolved oxygen, total phosphorus, orthophosphate-P, total nitrogen, nitrate-N, total inorganic nitrogen;
- Coastal waters: Transparency, dissolved oxygen, total phosphorus, orthophosphate-P, total nitrogen, nitrate-N, total inorganic nitrogen.
Systematic variation between both types and countries is apparent for several of these, although comparisons are complicated by differences in the ways that data have been reported.
