The presence of
Cr did not seem to affect the growth of Z. mays under cocontamination
of Cr and B[a]P. For example, when 50 mg of
Cr was combined with 1 and 5 mg of B[a]P, the 11 and 31 %
shoot dry weight reduction observed was not significant when
compared to shoot biomass in soil contaminated with 1 and
5 mg of B[a]P alone.
