Nitrite, an intermediate compound in the oxidation of ammonia nitrogen to nitrate by nitrifying bacteria in soil and water, is considerably more toxic than nitrate. Exposure to nitrite causes gill lesions and edema in the skeletal muscles of fish, and also affects respiration. Nitrite concentration is affected by the dissolved-oxy-gen and chloride levels in water, as well as species’ differences in nitrite susceptibility. Fish suffering brown-blood disease quickly recover when moved to water with low nitrite concentration.
