title: Identification of polycyclic aromatic hydrocarbons in mutagenic adsorbates to a copper-phthalocyanine derivative recovered from municipal river water.
abstract: A study was made to identify polycyclic aromatic hydrocarbons (PAHs) in the mutagenic adsorbate to blue cotton recovered from the water of the Katsura River which is a tributary of the Yodo River, a typical municipal river. As blue cotton bears a covalently bound copper-phthalocyanine derivative which can adsorb PAHs over 3 rings, PAHs in the adsorbate were separated into 4 fractions (I-IV) by Sephadex LH-20 gel chromatography. Fractions III and IV showed high direct and indirect frameshift mutagenicity in strains YG1021 and YG1024, the nitroreductase- and O-acetyltransferase-overproducing derivatives of TA98, especially in YG1024 with S9 mix, whereas these fractions showed less mutagenicity in TA98NR or TA98/1,8-DNP6. These results suggest that mutagenic nitroarenes and aminoarenes are present in both fractions. The retention times of some peaks separated from both fractions using high performance liquid chromatography (HPLC) with a fluorescence detector were identical with those of authentic PAHs. Gas chromatography-mass spectrometry of some HPLC fractions demonstrated that anthraquinone, azulene derivative, quinoline derivative, chrysene and benzo[b]fluoranthene are probably contained in these fractions.
