Applicant's summary and conclusion
- Executive summary:
The distribution of p-cresol in a "unit world" was calculated according to the Mackay fugacity model level I (Currenta, 2009) based on the physico-chemical properties. The main target compartment for p-cresol is water with 96.2 %, followed by air with 2.5 %, soil and sediment each with 0.7%.
