The U. V. absorption spectrum of benzpyrene dissolved in horse and rabbit sera is compared to that of benzpyrene dissolved in ethyl alcohol, cycloesane and vaseline oil. The absorption curve in serum, when compared with that in ethyl alcohol, shows a shifting towards higher values of λ in the region between 300 and 400 mμ and altered Mx/Mn ratios concerning the absorption bands. In 4 cases benzpyrene was re-extracted from serum with alcohol; the obtained spectrum often shows an anomalous behaviour. The possible causes of such variations and anomalies are discussed.
