tissue culture plate which was used with a disecting
microscope. A stock solution of ammonium sulfate was freshly
prepared, and used for further dilutions. 4 to 6 miracidia
were picked up in 1 ml dechlorinated water, and placed in
each well of the test chamber. 1 ml of double strength
ammonium sulfate solution was then added,according to the
test schedule, giving a total of 2 ml in each experimental
well. 6 Replicate concentrations were employed. The test
concentrations were 0 (control), 0.1, 0.2, 0.3, 0.4, and
0.5% ammonium sulfate. Careful hourly observations were made
under the disecting microscope. Motionless miracidia (round
shaped in the control group and elongated in the
experimental group) were recognised as dead.
STATISTICAL ANALYSIS: The EPA Probit statistical package
(EPA Probit Analysis Program Version 1.3) as used to
calculate LC5, LC50, and LC95 values after 2, 4, and 6 hours
of exposure.
Reliability: (2) valid with restrictions
Only the LC50 result at 4 hours is statistically robust.
Concentrations not measured. Limited documentation of
results.
