Nitrite toxicity to Danio rerio: effects of chloride concentrations during acclimatization and in toxicity tests

Popis výsledku v původním jazyce

The aquarium fish Danio rerio is the most frequently used species of fish for toxicity tests. The aim of the present study was to determine NO2- toxicity to D. rerio and to evaluate effects of chloride concentrations during acclimatization and in toxicity tests. The semistatic method according to OECD 203 was used in the tests. The 96hLC50 NO2- value for D. rerio was 242.41 +/- 13.67 mg l-1 at 19 mg Cl- l-1 in diluting water. There was a significant increase in 96hLC50 NO2- to 318.02 +/- 50.65mg l-1 and387.40 +/- 43.99 mg l-1 following an increase in Cl- concentration in diluting water to 50 mg l-1 (p < 0.05) and 100 mg l-1 (p < 0.01), respectively. A logarithmical relationship between 96hLC50 NO2- values and chloride concentrations in diluting water(R2 = 0.733) was demonstrated. A significant increase in 96hLC50 NO2- values was found in toxicity tests in D. rerio acclimatized to increased Cl- concentrations for 96 hours before the test. In these cases 96hLC50 NO2 was 378.81+/- 27.20
