Table 1. Average weight, sample size (n), and controls of A. clarkii pulse exposed to an acute dosage of 50 ppm CN for either 20 or 45 s across 2 trials and 2 chronic exposures of 100 ppm SCN for 12 days.
There were two groups (small/large) of A. clarkii used for CN 2 trial however fish size did not affect SCN half-life.
| Trial | Exposure time | Dose (ppm) | Sampling duration (days) | n | Controls | Average weight (grams ± S.D.) |
|---|---|---|---|---|---|---|
| CN 1 | 20 s | 50 | 13 | 44 | 5 | 3.1 ± 0.6 |
| CN 1 | 45s | 50 | 13 | 47 | 3.6 ± 0.8 | |
| Additional Controls | 9 | 18.9 ± 5.7 | ||||
| CN 2 | 45 s | 50 | 72 | 41 | 4 | 12.8 ± 9.4 Small: 5.1 ± 1.3 Large: 21.0 ± 6.8 |
