Abstract
In the preceding report, the authors investigated in the toxicity of some antioxidants, such as BHA, BHT, and hydroquinone. The authors also had reported the presence of these antioxidants in smoked foods. In this paper, the toxic characters of the smoke were further investigated by the growth test of mice.
The ethyl alcohol extract of silica gel, adsorbing the smoke, or each paper-chromatographic fraction of the extract was added to soybean oil, to prepare the testing materials.
The growth of mice fed with these oils was found to be worse as compared with that of control group. In some 20 days from the commencement of the experiment, the growth curve (in body weight) reached the peak and the features of the fur got worse
The strongest toxicity was present in the naphthol fraction of the smoke.
