Simulation study in sediment (similar to OECD 308):
The half-life of the parent compound in
water and sediment was 95
days (Lienden) and
76 days (IJzendoorn).
Aminotriazole® is a quickly acting herbicide which is taken up
predominantly through the leaves. From there the active ingredient is
transported with the assimilation stream into the roots and the
The active ingredient
1H-1,2,4-triazole-3-amine was given the common name amitrole. The
was investigated in two water-sediment systems using an aquatic, aerobic
test model especially developed for this purpose. Immediately prior to
the start of the test, water and sediment were taken from a fish
pond near Lienden (NL)
and from a
ditch in a fruit-growing area near Ijzendoorn (NL). The
amount of active ingredient applied was 5.0mg/I
and the incubation period was determined to be 91 days.
The active ingredient
was degraded to CO2
and incorporated into the sediment. The mineralization
rates after 91
days of incubation amounted to 19%
of the applied active ingredient in
the Lienden system (the sediment with the lower amount of
organic carbon) and 10
% in the
Ijzendoorn system. The half-life of the parent compound in
the water and sediment was 95days
(Lienden) and 76 days
only in low concentrations (=<3%).
Two metabolites, triazole and urea were identified by mass
