| Popis: | The 24-h median lethal concentration of nitrite (NO2 –) for striped bass Morone saxatilis was 163 mg/L in static toxicity tests. Exogenous chloride ions increased the tolerance of the fish for NO2 –; CaCl2 was more than twice as effective as NaCl. Plasma NO2 –, cortisol, and methemoglobin were correlated positively with environmental NO2 –. Plasma NO2 – and methemoglobin were correlated negatively with environmental Cl–, but cortisol was not reduced by the presence of environmental Cl–. Striped bass maintained NO2 – in the plasma (0–45 mg NO2 –/L) at concentrations below those in the environment (0–250 mg NO2 –/L). However, striped bass were sensitive to NO2 – that entered the plasma; methemoglobin levels greater than 60% and plasma NO2 –, levels greater than 70 mg/L resulted in significant mortalities. |
