In the model tris(2 -chloro-1 -methylethyl) phosphate 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 main target compartment for the main constituent of TCPP tris(2-chloro-1-methylethyl)phosphate in a "unit world" is water with 92.9 %, followed by soil with 3.52 %, and sediment with 3.55%.
Executive summary:

The distribution of the main constituent of TCPP tris(2 -chloro-1 -methylethyl) phosphate in a "unit world" was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment is water with 92.9 %, followed by soil with 3.52 %, and sediment with 3.55% (Currenta, 2009).
