Abstract: | Static acute toxicity tests of 4 and 7 days duration were performed on sea bass (Dicentrarchus labrax) and European eel (Anguilla anguilla). The 96-hour LC50 for sea bass (x?; = 5 cm) was 274, 220, and 154 mg/liter N-NO2 at water temperatures of 17, 23 and 27°C, respectively, in sea water. The 96-hour LC50 for eel elvers was 84, 213, 264, 503, 812 and 974 at salinities of 0, 6, 12, 24, 30 and 36 g/liter. |
