| Description
| - Subchronic toxicity of nitrite in rainbow trout (Oncorhynchus mykiss, mean mass ?SD, 18.9?1.3 g) was assessed in a 28 day trial. The influence of nitrite on fish mortality, growth rate, haematology, blood biochemistry and gill histology was observed. Survival was not affected by exposures up to 1 mg l-1 NO2- (at 10 mg l-1 Cl-). On the basis of growth rate inhibition data, the values of NOEC (28dLC0) and LOEC (28dLC10) were estimated at 0.01 mg l-1 and 0.2 mg l-1 NO2-, respectively. At 0.01 mg l-1 NO2- (the lowest concentration tested) there was segmental hyperplasia of the respiratory epithelium of secondary lamellae and elevated glucose and decreased potassium. Elevated nitrite concentrations were found in blood plasma of fish exposed to concentrations of 1.0 mg l-1 NO2- and higher, and in muscle tissue at the highest concentration 3.0 mg l-1 NO2-. Plasma and muscle nitrite levels were lower than those in the ambient water in all experimental groups.

- Subchronická toxicita dusitanů pro pstruha duhového (Oncorhynchus mykiss, průměrná hmotnost ?SD, 18,9?1,3 g) byla posuzována v 28 denním testu. Byl sledován vliv dusitanů na mortalitu ryb, růstovou rychlost, hematologické a biochemické parametry a histologii žaber. Přežití ryb nebylo ovlivněno koncentracemi >= 1 mg l-1 NO2- (při 10 mg l-1 Cl-). Hodnoty NOEC (28dLC0)= 0,01 mg l-1 a LOEC (28dLC10) = 0,2 mg l-1 NO2- byly vypočteny na základě výsledků inhibice růstu ryb. V koncentraci 0,01 mg l-1 NO2- (nejnižší testovaná koncentrace) byla pozorována segmentární hyperplasie respiračního epitelu sekundárních lamel a zvýšená hladina glukózy a snížená hladina draslíku v krevní plasmě ryb. Zvýšená koncentrace dusitanů byla změřena v krevní plasmě ryb exponovaných koncentracím 1,0 mg l-1 NO2- a vyšším, ve svalovině pak pouze v nejvyšší koncentraci (3,0 mg l-1 NO2-). Koncentrace dusitanů v krevní plasmě a svalovině ryb byly ve všech pokusných skupinách nižší než koncentrace v okolní vodě (koncentrace, kterým (cs)
