Applicant's summary and conclusion

Conclusions:
According to Mackay Level l model calculations, the main target compartment for dodecanedioic acid, the read-across chemical for Corfree® M1, will be water (79.4%), sediment (10.3%) and soil (10.2%). The air compartment is not expected to be relevant.
