CAS number: 77-85-0
Test substance (nominal)
[mg/L x h]
physico-chemical oxygen consumption has been determined at 1000 mg/L
test item concentration. As no physico-chemical oxygen consumption was
observed at that test item concentration this observation also holds
true for the lower test item concentrations.
The respiration inhibition of activated
sludge from predominantly domestic sewage treatment plant by
trimethylolpropane was determined according to the EU Guideline C.11
with an incubation time of 3 hours. The concentrations tested were 10,
100 and 1000 mg/L. EC50 of the reference substance 3,5 - dichlorophenole
was 9.2 mg/L ( 95% C.I. 3 - 24 mg/L). The respiration rates of the 2
controls differed less than 15% from each other.
The EC50 and the EC10 for trimethylolpropane
were determined to be > 1000 mg/L.
The validity criteria of the guideline are
fulfilled. The deviation from the guideline used is considered to have
no negative impact on the result.

Assessment is by read-across to the source substance trimethylolpropane
(CAS No: 77-99-6).
