Biological Quality Elements (BQE)
General description
For the implementation of the Water Framework Directive, the assessment of ecological status of water bodies is based on biological indicators from several groups of organisms known as biological quality elements (BQE). Four inland surface waters these are:
- Phytoplankton
- Macrophytes and phytobenthos
- Benthic Invertebrates
- Fish
The evaluation of the status of the water bodies may be complemented with hydromorphological (HYMO)quality elements and/or physicochemical quality elements.<p/>
