Movement & Partitioning
Bioconcentration potential is low (BCF less than 100 or log Pow less than 3). Potential for
mobility in soil is very high (Koc between 0 and 50).
Henry's Law Constant (H): 9.78E-4 atm*m3/mole; 25 °C Measured
Partition coefficient, n-octanol/water (log Pow): 0.10 Measured
Partition coefficient, soil organic carbon/water (Koc): 1.29 - 14 Estimated
Persistence and Degradability
Material is expected to biodegrade only very slowly (in the environment). Fails to pass
OECD/EEC tests for ready biodegradability.

ECOTOXICITY
Data for Component: Diphenylmethane Diisocyanate, isomers and homologues
The measured ecotoxicity is that of the hydrolyzed product, generally under conditions
maximizing production of soluble species. Material is practically non-toxic to aquatic
organisms on an acute basis (LC50/EC50 >100 mg/L in the most sensitive species tested).
Toxicity to Soil Dwelling Organisms
LC50, Earthworm Eisenia foetida, adult, 14 d: > 1,000 mg/kg
Data for Component: 4,4' -Methylenediphenyl diisocyanate
The measured ecotoxicity is that of the hydrolyzed product, generally under conditions
maximizing production of soluble species. Material is practically non-toxic to aquatic
organisms on an acute basis (LC50/EC50 >100 mg/L in the most sensitive species tested).
Toxicity to Soil Dwelling Organisms
LC50, Earthworm Eisenia foetida, adult, 14 d: > 1,000 mg/kg
Data for Component: Isocyanic acid, polymethylenepolyphenylene ester, polymer with
.alpha.,.alpha.',.alpha.''-1,2,3-propanetriyltris[.omega.-hydroxypoly
The measured ecotoxicity is that of the hydrolyzed product, generally under conditions
