    Abstract:
    Binary mixtures of benzo(a)pyrene (B(a)P) and benzo(e)pyrene (B(e)P) produce synergistic mutagenic (comutagenic) responses in Salmonella typhimurium strain TA98 (a frameshift detector). The optimum enhancement (25 X) was found at B(a)P concentration of 0.3 microgram/plate and B(e)P concentration of 1.5 microgram/plate. The response of strain TA100 (mostly a base-substitution detector) is opposite that of TA98, showing antagonism and additivity in similar concentration ranges.
