The toxicity of ammonia and its effects on growth inhibition for the marine ciliate, Euplotes vannus, were measured in a conventional open system. Linear regression analysis showed that: the 2 hour median lethal concentration (LC50) was 7870.46 mg total ammonia-N l−1 (P<0.05; pH 8.2; salinity 28 ppt; temperature, 25 °C ); the threshold concentrations for… CONTINUE READING
