Seafood
consumption should not be ignored because the cancer risk for the coastal
people due to metal exposure. Exposure to high lead levels can severely damage
the brain, liver, and kidneys and ultimately cause death. Even lead may cause
miscarriage to pregnant women.
The
carcinogenic risk for As was close to the unacceptable range in crustacean and
fish species, whereas that of Cd was higher than the unacceptable value in both
groups. In the case of Pb, the lowest limit that indicated negligence is lower
than 10−6 in fish, but the highest limit, which lies between 10−6
and 10−4 indicated an acceptable range in both group of species.
According
to USEPA 1989, 2010, the excess cancer risk lower than 10−6 is
considered to be negligible, the cancer risk above 10−4 is
considered unacceptable, and risks that lie between 10−6 and 10−4
are considered acceptable.
