Abstract
This investigation represents an initial evaluation of the effects of ethanol on the responses of normal human and sheep erythrocytes (in vitro) to six known oxidant stressor agents (i.e. chlorite, copper, nitrite, carbaryl, α‐naphthol, and menadione). The results indicated that the ethanol incubation treatment (5%) enhanced the occurrence of oxidant stress in five of the six agents with the erythrocytes using increased methemoglobin and reduced glutathione as metabolic indicators of stress. Carbaryl was the only agent whose toxicity was not modified by the ethanol treatment.
