    Abstract

    A 0.5% 2-nitroso-1-naphthol acetone solution was studied for its potential as a trace metal detection reagent. A metal object must be held for approximately 1.5 min for satisfactory color and pattern formation to be observed by this procedure. Metal ions transferred through a brief period of holding can be detected within 3 h. Best results were obtained on individuals with high levels of perspiration. That more than one metallic object was held can be revealed if the objects are made of different metals or have distinct shapes or sizes.
