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: 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/EL50/LL50 >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: Polymethylenepolyphenyl polyisocyanate, polypropyleneglycol copolymer
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/EL50/LL50 >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
maximizing production of soluble species. Material is practically non-toxic to aquatic
organisms on an acute basis (LC50/EC50/EL50/LL50 >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: Tris(1-chloro-2-propyl) phosphate
Material is slightly toxic to aquatic organisms on an acute basis (LC50/EC50/EL50/LL50
between 10 and 100 mg/L in the most sensitive species tested).
Fish Acute & Prolonged Toxicity
LC50, bluegill (Lepomis macrochirus), 96 h: 84 mg/l
Aquatic Invertebrate Acute Toxicity
EC50, water flea Daphnia magna, 48 h, immobilization: 63 mg/l
