Fig. 1 — Direct-acting (i.e., −S9) and indirect-acting (i.e., +S9) mutagenic potencies of the nonpolar neutral and semipolar aromatic soil fractions measured during day 0, 3, 7, 24, and 29 of the bioremediation treatment in Salmonella strains TA98 (), YG1041 (), and YG1042 (). Note that TA100 did not detect any mutagenic activity in any samples on any days.
