The relationship between nitrite concentration and degree of methemoglobinemia has been documented in catfish; however, the influence of temperature on this process has not been examined. In light of the effects of temperature on the movement of chemicals, it is tempting to hypothesize that higher temperatures always increase toxicity. A temperature change may result in an increase, decrease or no change in the toxicity of a chemical pollutant. The authors conducted research to measure the effect of temperature on methemoglobin formation and recovery in nitrite-exposed channel catfish.
