PRELIMINARY TOXICITY TEST
The test substance was
supplied as a solution in distilled water at 50% (500 mg/ml).
Consequently, with a maximum dose volume of 100 ul/plate, the
dose-Ievels were: 10, 100, 500, 1000, 2500 and 5000 ug/plate. No
precipitate was observed in the Petri plate when scoring the revertants.

The number of revertants of
the vehicle and positive controls was as specified in the acceptance
criteria and within the range of our historical data. Since the test

ug/plate, according to the criteria specified in the international

5000 ug/plate. The test substance did not induce any significant
