The toxicity to microorganisms of the registration substance
Hostapon SLG was evaluated based on the read-across approach using the
toxicity to microorganisms data of Hostapon SG.
A Respiration Inhibition Test with
activated sludge according to OECD Guideline No. 209 was carried out
with the test item Hostapon SG (batch number:ESD0006364)
from 2012-01-10 to 2012-02-07, with the experimental phase on 2012-02-07
system was activated sludge of the municipal treatment plant of D-31137
Hildesheim. The test was carried out under static conditions with the
nominal active ingredient concentrations 100 - 180 - 320 - 580 - 1000
mg/L. The respiration rates of the control, reference and test item
replicates were measured after a contact time of three hours, and the
inhibitory effects of the test and reference item were determined in
comparison to the control respiration rates. The mean inhibition of
respiration for the test item replicates ranged from -33 % to 62 %.
In order to check the activity of the
test system and the test conditions a reference test was carried out
with copper (II) sulphate pentahydrate as reference item and the
reference toxicity was determined. The EC50-value for the
reference item was 129 mg/L.
