Persistence and Degradability
In the aquatic and terrestrial environment, material reacts with water forming predominantly
insoluble polyureas which appear to be stable. In the atmospheric environment, material is
expected to have a short tropospheric half-life, based on calculations and by analogy with
related diisocyanates.
Data for Component: Tris(1-chloro-2-propyl) phosphate
Movement & Partitioning
Bioconcentration potential is low (BCF < 100 or Log Pow < 3). Potential for mobility in soil is
low (Koc between 500 and 2000).
Henry's Law Constant (H): < 1.35E-5 atm*m3/mole; 25 °C Estimated
Partition coefficient, n-octanol/water (log Pow): 2.59 Measured
Partition coefficient, soil organic carbon/water (Koc): 1,300 Estimated
Bioconcentration Factor (BCF): 0.8 - 4.6; common carp (Cyprinus carpio); Measured
Persistence and Degradability
Material is expected to biodegrade only very slowly (in the environment). Fails to pass
OECD/EEC tests for ready biodegradability.
Indirect Photodegradation with OH Radicals
Rate Constant Atmospheric Half-life Method
4.47E-11 cm3/s 0.24 d Estimated
OECD Biodegradation Tests:
Biodegradation Exposure Time Method
14 % 28 d OECD 301E Test
Theoretical Oxygen Demand: 1.17 mg/mg
Data for Component: 4,4' -Methylenediphenyl diisocyanate
Movement & Partitioning
In the aquatic and terrestrial environment, movement is expected to be limited by its reaction
with water forming predominantly insoluble polyureas.
Persistence and Degradability
In the aquatic and terrestrial environment, material reacts with water forming predominantly
insoluble polyureas which appear to be stable. In the atmospheric environment, material is
expected to have a short tropospheric half-life, based on calculations and by analogy with
related diisocyanates.
ECOTOXICITY
Data for Component: Methyl ether
Material is practically non-toxic to aquatic organisms on an acute basis (LC50/EC50 >100
mg/L in the most sensitive species tested).
Fish Acute & Prolonged Toxicity
LC50, guppy (Poecilia reticulata), 96 h: > 4,000 mg/l
Aquatic Invertebrate Acute Toxicity
LC50, water flea Daphnia magna, 48 h: > 4,000 mg/l
Data for Component: Propane
