CAS number: 142-96-1
A 96-hr static exposure was conducted with di-n-butyl ether (DnBE) exposed to the green alga Pseudokirchneriella subcapitata. The 72-hr ErC50 for specific growth rate was 19.1 mg DnBE/L and the NOEC was 8.91 mg DnBE/L.
The compound di-n-butyl ether (DnBE) was evaluated for its effects on
the growth of the green alga Pseudokirchneriella subcapitata ,
over a 96-hour static exposure period. The data from this key study were
used to determine the 72- and 96-hour ErC50s (based on growth rate),
EyC50s (based on cell density), and no-observed-effects concentrations
(NOECs) for each endpoint. Based on mean measured concentrations, the
72-hour calculated ErC50 (95% confidence intervals) for specific growth
rate was 19.1 (10.1, 28.2) mg DnBE/L and the NOEC was 8.91 mg DnBE/L. A
supporting study was also available that reported the toxicity of
dibutyl ether (DnBE) to the blue-green algae (cyanobacteria), Microcysis
aeruginosa. The 8 day NOEC was >= 50 mg/L.
