The Physiological Aspects of Pollution

     Theo Colborn had been conducting a series of wildlife research experiments in
the Great Lakes region when she became convinced that common chemicals widely used
in American homes and industries were affecting males of all species.  Among the many
harmful effects of these seemingly ordinary chemicals were dramatic reductions in
fertility and a growing number of gross deformities in the male anatomy, including
shrunken penises and testicular problems.  Colborn believes popular chemicals used for
growing food, treating and purifying water, manufacturing plastics, and producing pulp
and paper are damaging the endocrine, immune, and reproductive systems of animals.
Moreover, the chemicals are creating these effects at exposure levels far below accepted
safety limits, thresholds typically set for measuring cancer risks.  By far, the most
troubling impacts occur in the womb, where the chemicals circulating in the mother's
body may deliver a profound punch to the developing embryo and fetus.  Colbron calls
this a "transgenerational effect."  Any fetal damage is permanent and irreversible,
although the results may not appear until early adulthood.  And, she notes, the pollutants
could have been absorbed years earlier by the body, only to wreak havoc during
childbearing.  According to Colborn, "the effects are being seen in the offspring more
than the parents.  The problem is that people don't understand that these chemicals are
affecting fertility, the doorway to population."

     Louis Guillette, a Wingspread scientist at the University of Florida, told a group
of lawmakers at a recent Congressional hearing that:  "Every man in this room is half the
man his grandfather was."  Guillette's remarks referred to the fertility investigations of
Neils Skakkebaek, a Danish scientists, and other Europeans.  According to Skakkebaek,
sperm totals for men have declined 50 per cent since the 1940's.  Skakkebaek's
conclusion is based on analysis of sixty-one sperm-co...
