Název v původním jazyce

Nitrite toxicity to Danio rerio: Effects of fish age and chloride concentrations.

Popis výsledku v původním jazyce

The aim of the present study was to compare the acute nitrite toxicity for Danio rerio at age of 20 - 25 days (larval stage) and 2 - 3 months (juvenile stage) at various chloride concentrations. The semistatic method according to OECD 203 was used in tests. The 96hLC50 NO2- value was 386.00 +/- 29.75 mg.l-1 (D. rerio aged 20 - 25 days), resp. 242.41 +/- 13.67 mg.l-1 (D. rerio aged 2 - 3 months) at 19 mg Cl-.l-1 in diluting water. There was observed an increase in 96hLC50 NO2- in D. rerio of both developmental stages following an increase in Cl- concentration in diluting water. A comparison between the 96hLC50 NO2- determined for D. rerio aged 20 - 25 days and those aged 2 - 3 months at different chloride concentrations in diluting water (19; 50; 100 mg.l-1) showed a highly significant increase (p < 0.01) in the 96hLC50 NO2- for the younger fish at all chloride concentrations. An exponential relationship between 96hLC50 NO2- values and chloride concentrations in diluting water (I = 0.84
