The Effect of Dilute Corrosives on the Esophagus

Abstract

Cats were used in this study to demonstrate the effect of dilute corrosive drain cleaners upon the esophagus. Sulfuric acid, potassium hydroxide, and sodium hydroxide in less than 10% strength all produced gross and microscopic evidence of severe damage after 30-second exposure. We suggest that presently allowable concentrations of these agents for household use should be banned and cite clinical data on accidental injury in childhood to suggest that "child-proof" packages will not afford much protection.
