Abstract
Several preconcentration methods for the detection of organic mutagens in water, including blue rayon and XAD-2 resin column methods, were compared. The mutagenicity test of the extracts from blue rayons hung at the six points of the Yodo river revealed similar frame-shift type mutagenicity to our previous report with the XAD-2 resin column method. For the quantitative concentration of polycyclic aromatic hydrocarbons in water, it was shown that the blue rayon column method was more efficient than the blue rayon hanging method or XAD-2 resin column method. Extracts from the Yodo river water and sewage treatment plant effluent obtained by the XAD-2 resin column and blue rayon hanging methods may contain nitroarenes and aminoarenes.
