Measured exposure concentrations were 0, 6, 11, 25, 51 and 110 mg/l.
Embryo hatchability was 96% - 98%, with no treatment-related differences
apparent, however the percentage of normal larvae was decreased
significantly in the 51 mg/l and 110 mg/l tanks (decreased 33% and 100%,
respectively). Body weight at day 28 was reduced significantly in larvae
exposed to 11 mg/l and above, while larval survival was significantly
decreased at 25 mg/l and above. The authors estimate that the Maximum
Acceptable Toxicant Concentration (MATC, defined as a hypothetical toxic
threshold falling mid-way between the NOEC and LOEC) for PDC is 59 mg/l.
