Any other information on results incl. tables

In the model 6.6`-Di-tert.-butyl-2.2`-methylenedi-p-cresol is treated as a type 1 chemical, i.e. the chemical partitions into all environmental media. Estimation is carried at an environmental temperature of 25 °C.

Applicant's summary and conclusion

Conclusions:
The distribution of 6.6`-Di-tert.-butyl-2.2`-methylenedi-p-cresol in the environment was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment for 6.6`-Di-tert.-butyl-2.2`-methylenedi-p-cresol is sediment with 49.9 %, followed by soil with 49.4 %, water with 0.35 % and suspended sediment with 0.32 %.
