EC number: 251-718-8
CAS number: 33885-52-8
A measured Koc value of 12000 (log Koc 4.07) indicates that the
substance has strong potential to adsorb to sediment/soil.
Henry coefficient: To assess the volatilisation potential of the
substance a Henry's law constant was calculated using EUSES, which
showed a value of 36.6 Pa. m3/mol (at 12 °C). Based on this value
partitioning from water to air may be expected.
Based on Level III environmental distribution modelling using
EPISUITE (assuming equal and continuous releases to air, water and
soil) using the CAS number 33885-52-8 and the measured physico-chemical
parameters (water solubility and log Kow) as input, it is estimated that
the majority of the substance released to the environment will partition
mainly into soil (83.8%) and water (15.8%) with minor amounts to air
(0.1%) and sediment (0.3%).
The SimpleTreat model simulates the distribution of the substance
in a Sewage Treatment Plant. Model calculations (default assumptions,
local) show that 0% of the substance will be degraded and that 30.5%,
53.2% and 16.3% will partition to water, sludge and air, respectively.
