A closer look at the change in quality elements shows some improvement (Figure 2.7). The improvements are seen in all the most commonly used Biological quality elements (BQEs) in rivers, and in phytoplankton in transitional waters, but is less clear in phytoplankton in lakes and benthic invertebrates in coastal and transitional waters. For phytoplankton in coastal waters, there is even a slight deterioration.
Most of the changes are not reported as consistent, but are rather due to changes in methodology. However, many countries have not reported on consistency, so it is unclear how the changes should be interpreted.

Due to different definitions, no clear picture can be given from macrophyte/phytobenthos/etc. Only when you look at different categories and parameters, some combinations show an improvement.

Changes have been indicated by MSs, but do not necessarily mean significant changes.

For RW benthic invertebrates there is no improvement in fig 2.7?!
