Applicant's summary and conclusion

Conclusions:
The main target compartment for N-isopropyl-N'-phenyl-p-phenylenediamine is water with 88.40 %, followed by sediment with 4.16 %, soil with 4.12 % and air with 3.28 %.
Executive summary:

The distribution of N-isopropyl-N'-phenyl-p-phenylenediamine in a "unit world" was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment for N-isopropyl-N'-phenyl-p-phenylenediamine is water with 88.40 %, followed by sediment with 4.16 %, soil with 4.12 % and air with 3.28 %.
