Determination of organic mercury in various kinds of household necessities, such as clothes, belts, shoe polish, etc., was examined. The organic mercury was extracted with carbon tetrachloride in a hydrochloric acid medium, reextracted from the carbon tetrachloride layer with aqueous solution of cysteine acetate, and then determined by atomic absorption spectrophotometry combined with pyrolysis and the gold amalgamation technique. The recovery of phenylmercuric acetate from cotton and wool cloths was tested in hydrochloric acid of various concentrations. The most appropriate concentration of hydrochloric acid was 1 N for cotton cloth, and 2 N for wool cloth. Recovery was 97 % in the former and 73 % in the latter. All samples analysed contained organic mercury but not more than 0.03 μg/g. There were no articles sanitized with phenylmercuric compounds.
