no
other TS: Fire-Trol 100 (ammonium sulfate with n attapulgite
clay thickener, no further details)
Result:
for formulation
EC50 = 62 mg/l
Test condition: Static tests wer conducted in reconstituted water with a pH
of 7.4 (pH of Fire-Trol-solution: 6.9 to 7.1).
TEST ORGANISM: gammarus pseudolimnaeus (scud).
Test substance: Fire-Trol (= 63.5 % (NH4)2SO4
Reliability: (2) valid with restrictions

Exposure period: 48 hour(s)
Unit: mg/l Analytical monitoring: no data

no data
other TS: ammonium sulfate, not further specified
Remark:
Following 48 hour exposure, the concentrations of ammonium
sulfate killing 100% of freshwater snails were 1250 mg/L
and 1000 mg/L for the adults of Helisoma trivolvis and of
Biomphalaria havanensis, respectively. 48-hour LC50 values
were 700 and 491 mg/L for Heliosoma trivovis and
Biomphalaria havanensis, respectively.
Results indicate 24 hour LC50 values of 558 mg/L and 669
mg/L for eggs, 393 mg/L and 526 mg/L for juveniles, and 701
mg/L and 657 mg/L for adults of Helisoma trivolvis and
Biomphalariahavanensis, respectively.
Test condition: Eggs, juveniles or adults of the two species were exposed
for 24 or 48 hours. Details of the method were referred to a
companion paper.
