Updated standard concentrations for the sum of PAH16 and individual PAHs, especially for rural areas
Updated values for standard concentrations for stormwater and base flow for PAH16 and respective individual PAHs for all rural types of land use such as woodland and meadows etc. and also for allotment area. Many values were previously stated as 0 in concentration for the individual PAHs, which have now been updated with estimated concentration data, which is lower than for other land uses, but this will give slightly higher estimated total concentrations and loads than before if these land uses are used.
The updated concentration data are marked in the database and implemented for new projects that are started as from 2019-05-27.
