Results: NOEC = 1.02 mg/L
Analytic Monitoring: Yes [ ]; No [ ]; ? [X]
Method: The publication summarizes the results of a series of critical life stage
(embryolarval) tests, which are defined as exposure during the embryogenic
period (incubation of the eggs), followed by exposure of fry for a period of
30-days after hatching for warm water fish with embryogenic periods ranging
from 1 to 14 days.

EG&G Bionomics (now Springborn Smithers Labs) using standard protocols.
The minimum threshold concentration, defined as the lowest concentration
causing significant effect on any parameter, was reported as >1.02 mg/L
