EC number: 309-811-7
CAS number: 101033-44-7
No studies were
conducted on the target substance, Tetrakis
[[2,2',2"-nitrilotris[ethanolato]](1-)-N,O]zirconium. As the target
substance hydrolyses rapidly (half-life < 30 minutes) the intrinsic
properties are related to hydrolysis products of the target substance.
On the basis that if
entering the environmental, this substance will quickly dissociate to
form the inorganic (poorly soluble) zirconium dioxide and
2,2',2''-Nitrilotriethanol (triethanolamine). The zirconium dioxide is
not considered further in this report as aquatic toxicity assessments do
studies of triethanolamine are well-investigated:
Fish: LC50 (96h),
Pimephales promelas, was 11800 mg/l (Geiger, D.L. et al., 1985)
(24h) Daphnia magna, was 1850 mg/l (Bringmann
cyanobacteria: EC50 (72h),Desmodesmus
subspicatus, was 512 mg/l (Aman
and Steinhaeuser, 1986)
(3h), activated sludge, > 1000 mg/l (Klecka, et al. 1985).
