Applicant's summary and conclusion
- Conclusions:
- According to a Mackay Level I model calculation the main target compartment for 1,2,3,4-tetrahydronaphthalene will be the atmosphere (94.6 %) followed by the hydrosphere (2.7 %), sediment and soil (1.3 % each).
- Executive summary:
The distribution among different compartments of 1,2,3,4 -tetrahydronaphthalene was explored through the Mackay level I model calculations. According to this calculation the main target compartment for 1,2,3,4-tetrahydronaphthalene will be the atmosphere (94.6 %) followed by the hydrosphere (2.7 %), sediment and soil (1.3 % each).
