1: Results of the activated sludge respiration inhibition test
Loading rate (mg/l)
Oxygen conc. At start (mg O2/l)
Oxygen consumption (mg O2/l/h)
Triethoxy(2,4,4-trimethylpentyl)silane replicate (1)
Triethoxy(2,4,4-trimethylpentyl)silane replicate (2)
Toxicity to microorganisms: ASRI 3-hour EC50 >100 mg/L (OECD 209).
An activated sludge respiration
inhibition 3-hour EC50 (total respiration) value of >100 mg/L
was determined for the substance in a reliable study conducted according
to an appropriate test protocol and in compliance with GLP. The result
is considered to be reliable.
Under the conditions of this
present test, triethoxy(2,4,4-trimethylpentyl)silane was not toxic to
wastewater (activated sludge) bacteria up to and including a loading
rate of 100 mg/L.
The EC50 exceeded a
loading rate of 100 mg/L.
