Any other information on results incl. tables

For estimation of emissions from wide dispersive uses (e.g. consumer products) the ERC 8a was selected allowing the application of sludge from STPs on soil.

Applicant's summary and conclusion

Conclusions:
Based on the calculation for diffusive emissions - ERC 8a - (STP sludge application allowed) freshwater, seawater and soil are the major compartments of concern
