Resumen:
In this study, the genotoxic effect of contaminants was assessed through
detection of DNA damage using the micronucleus (MNs) test in
erythrocytes from 149 flounder fish collected in two regions of the Gulf
of Mexico (GoM). The frequency of microcytes (MCs) was also evaluated in
the same group of fish collected from the Perdido Foldbelt (PF) and the
Yucatan Platform (YP). The MCs frequency was different among locations
of the YP (p = 0.011), while MNs frequency varied among locations of PF
(p = 0.024). MCs and MNs values correlated with heavy metals from fish
muscle, fish species and localities. Mean number, prevalence, and
intensity of MCs and MNs correlated with Al, PAHs, depth, and locality.
MNs frequency showed a species-specific association (p = 0.004). MNs and
MCs were associated with heavy metals and PAHs from fish muscle and
sediments, and the MNs frequency was species dependent.
