The gist of Drs Ames and Gold's (et al) research is that trace and
even moderate chemical exposures are not plausible cancer triggers.
About half of all chemicals tested, whether synthetic or naturally
occurring, even chemicals most prople are continually exposed to, will
test positive as 'potent cacinogens' using the current metrics. Yet
the age and discovery weighted cancer rate has been slowly falling for
about 100 years.
