For easier use, the management of input data in the box Recipient data has been clarified.
Depending on the substance, the criteria concentration for the recipient may refer to total, dissolved or bioavailable concentration.
Available measured data is filled in the box so that specified concentration (calculated or measured) in the recipient is used and corresponds to the fraction the criteria concentration is referring to.

In the box Water quality criteria, a criteria concentration for the specific recipient regarding phosphorus (P) can now be calculated.
The calculation is performed according to HVFMS 2013: 19. By using a criteria concentration (P) specific for the recipient, a better assessment of the load to reduce upstream is provided.
