Abstract

The sensitivity of Tiburonella viscana to K2Cr2O7 was evaluated from 18 water-only toxicity tests. The mean 48h-LC50 was estimated as 11.217 ± 3.768 mg/l, and the warning limits were calculated (mean LC50 ± 2 SD) as being between 3.68 and 18.75 mg/l. These results are baseline for the species and can be used for future comparisons in toxicity tests.
