Abstract
Some metabolites of naphthalene, including l-naphthol, 2-naphthol, l:2-dihydronaphthalene-l:2-diol, l-naphthvlsulfuric acid, 1-naphthylmercapturic acid, 1-naphthylglucosiduronic acid and 1:2-dihydro-1-naphthylglucosiduronic acid, can be estimated by the area of the spots which they form on paper chromatograms. Confidence limits have been determined for the calculated regression lines of best fit relating spot areas with the amounts of each metabolite present.
