to a Mackay Level I model calculation, the main target compartment for
will be the hydrosphere (99.999 %). The calculated Henry’s Law constant
of 0.0000006 Pa m³/mol at 20 °C indicates very low volatility of
from surface waters. With a Koc of 0.5 l/kg, there is no relevant
sorption potential of the substance to soil or sediment organic matter
calculated rate constant for the OH sensitized photodegradation of
approximately 87.8E-12 cm3/(molecule * s). At 500,000 OH radicals / cm3
(typical for central Europe), this corresponds to a half-life of 4.4
hours (24 hour-days). Hydrolysis is very slow under environmental
conditions. While no ready biodegradation was observed in a manometric
respirometry test, degradation rates up to 20% indicate a potential for
biodegradation, which is expected to be the predominant way of removal
from the environment. The partition coefficient 1-octanol/water was
determined as log Kow = -1.32 at 20.6 °C, indicating negligible
potential for bioaccumulation.
