According to Mackay Level I model calculations, the main target compartment for dodecanedioic acid will be water (79.4 %) followed by sediment (10.3 %) and soil (10.2 %). The air compartment is not expected to be relevant. The calculated Henry’s law constant of 1.15E-7 Pa m3/mol indicates very low volatility of dodecanedioic acid from surface waters. With an experimental (HPLC) Koc of 40 (dissociated) to 79 (undissociated) l/kg, the sorption potential of dodecanedioic acid to soil or sediment organic matter is expected to be very low (Blume scale).
