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).
