Any other information on results incl. tables

A fugacity level III calculation, using a four compartment (air, water, soil and sediment) model has been conducted using the Mackay model. A 100 % release to the water compartment was assumed. Based on the results of the calculation, peracetic acid is expected to partition almost exclusively to the aquatic compartment (99.95 %) with the remainder to sediment (0.040 %), soil (0.002) and air (0.009 %). The high water solubility, low vapour pressure and low octanol-water partition coefficient explain why peracetic acid is mainly found in the water compartment.

Applicant's summary and conclusion

Conclusions:
Based on a fugacity level III calculation, using a four compartment (air, water, soil and sediment) model using the Mackay model. Assuming a 100 % release to the water compartment shows that peracetic acid can be expected to partition almost exclusively to the aquatic compartment (99.95 %) with the remainder to sediment (0.040 %), soil (0.002) and air (0.009 %).
