The effects of Santicizer 278 on soil
nitrogen transformation by microorganisms were determined in a 28-day
soil nitrogen transformation study completed in accordance with OECD TG
216. An estimated EC50 (nitrogen transformation inhibition) of 857.27
mg/kg dw, and NOEC (nitrogen transformation inhibition) of 100 mg/kg dw
were determined for Santicizer 278.
A study was performed to determine the
effects of Santicizer 278 on the reproduction and growth of the
earthworm, Eisenia fetida. The method followed in this study was that
described in OECD Guideline for the Testing of Chemicals No.222 (2016),
Earthworm Reproduction Test (Eisenia fetida/Eisenia andrei), adopted 29
July 2016. There were no significant effects on the mortality or
bodyweight of adult worms or the number of juveniles produced at any
dose rate. The NOEC for adult mortality (28 days), adult bodyweights (28
days) and reproduction (number of juveniles at 56 days) was 1000 mg/kg
dry soil, which was the highest dose tested.
A study was conducted to determine the
phytotoxic effects of the test item, Santicizer 278, on seedling
emergence and growth of six non-target plant species, consisting of four
dicotyledons (cabbage, carrot, lettuce and tomato) and two
monocotyledons (onion and ryegrass), during early critical stages in
their development. The NOEC for germination and survival was 1000 mg/kg
soil dry weight the highest dose tested. The NOEC values for effects on
dry weight compared against the solvent control were 37.04 mg a.i./kg
dry soil for tomato, and 1000 mg a.i./kg dry soil for cabbage, carrot,
lettuce, onion and ryegrass.
