Administrative data

Endpoint:
distribution modelling
Type of information:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
other information
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: generally accepted calculation method (calculation not available), the data, however, were evaluated in the frame of the OECD SIDS program and therefore regarded as valid

Applicant's summary and conclusion

Conclusions:
According to the Mackay Level III calculation, the main target compartment of the distribution is air (ca. 99%) if the chemical is released into the air. If the chemical is released to the hydrosphere, the main target compartments are water (ca. 20 -23%) and sediment (ca. 75 -80%) and if the chemical is released to soil, the chemical remains predominantly in the soil compartment (ca. 98%).
Executive summary:

According to the Mackay Level III calculations, the main target compartment of the distribution is air (ca. 99%) if the chemical is released into the air. If the chemical is released to the hydrosphere, the main target compartments are water (ca. 20 -23%) and sediment (ca. 75 -80%) and if the chemical is released to soil, the chemical remains predominantly in the soil compartment (ca. 98%).
