MORE JUSTICE FOR CHEMICALS THAN FOR PRESIDENTS


	In this country not only do we hold people innocent until proven
guilty, we do the same for chemicals.  Their behavior may be suspect, they may
be found regularly at the scenes of crimes, they may fail their lab tests, but
still we let them go free -- indeed we multiply, spread, and circulate them --
until someone proves beyond all doubt that they are  harmful.  The standard of
"beyond all doubt" we use for chemicals is considerably higher than the one we
use for presidents.

	Examples cross my desk and e-mail daily.

	Minnesota schoolchildren are finding deformed frogs by the thousand. 
Frog and toad populations are plummeting mysteriously in many parts of the
world.  Now comes a report in the Journal of Environmental Toxicology and
Chemistry about researchers in Switzerland exposing developing frogs to a
fungicide called triphenyltin.  (Minnesota sugarbeet farmers use over 100,000
pounds of triphenyltin a year.  Georgia farmers use even more on pecans.)  The
fungicide stunts the growth of tadpoles and retards the sexual development of
adult frogs.  It acts differently on different species, but, says one of the
researchers, the chemical "may contribute to the . . . decline of populations
of more-sensitive amphibian species."

	The Kansas City Star reports that households in northeast Kansas are
being supplied with bottled water, because unacceptable levels of a
cancer-causing chemical have been found in their drinking water.  The chemical,
vinyl chloride, was first found to be harmful when it caused cancers in workers
in polyvinyl chloride (PVC) plastic factories.  The source of the chemical in
the Kansas water is PVC piping made before 1975.  Those early PVC pipes, it
turns out, leach vinyl chloride into water.

	An article in press in the journal Environmental Health Perspectives
says that a whole family of widely used chemicals tests positive for estrogen
mimicry.  Estrogen is a powerful hormone, a message-carrier that regulates
sexual development and behavior in both males and females.  Chemicals that
behave like estrogen can mess up the body's signaling systems, especially the
system that tells an embryo how to develop into a healthy, functional baby.

	The suspicious chemicals are called hydroxylated diphenylalkanes or
bisphenols.  They occur in plastics used for everything from household dishes
to drinking water containers (that Kansas bottled water might have problems of
its own) to the enamel substitutes used to fill teeth.  The new article says,
"Because diphenylalkane derivatives are widespread and their production is
increasing, potential exposure to estrogenic diphenylalkanes both in the
workplace and the home environment is becoming a significant issue. The
hazardous effects of continuous exposure to bisphenol-releasing chemicals in
exposed workers and in general populations demand investigation."

	Then there are the alligators.  A pesticide spill about 15 years ago in
a Florida lake called Apopka led scientists to be worried about
estrogen-mimicry in the first place.  The pesticide caused the alligators in
the lake to develop improperly, especially the males, which had shrunken
penises and could not reproduce.

	New research, to be published next month in Environmental Toxicology,
reveals that it doesn't take a spill to emasculate alligators; agribusiness as
usual will do the trick.  The male alligators in three Florida lakes, including
huge Okeechobee, have depressed testosterone levels.  Females have elevated
levels of estradiol, the principle estrogen found in all vertebrates.  The
alligators also have problems with thyroid hormones, which govern brain
development and metabolism.

	"It raises a major red flag for us," said researcher Louis Guillette to
a Reuters reporter. "It could mean that these animals would not mature
properly.  They could have altered reproduction.  They could have altered
resistance to disease.  In Florida, we have a couple of major problems.  We
have extensive development taking place that's very rapid.  And we have growing
seasons that go 12 months out of the year," so there's no let-up in the use of
pesticides.

	I haven't got space here for the latest on the falling human sperm
count.  Or the article about how the insecticide chlorpyrifos (trade name
Dursban or Lorsban), used for fumigating houses and treating pets for fleas,
clings to objects such as children's plush toys for hours or days after the
chemical has been used.
	But I should mention that the chemistry of all life is similar. 
Something that can interfere with the operation of a fungus or a flea or a frog
or an alligator could also interfere with us.

	 The point isn't to worry about any one chemical.  The point is that
our innocent-till-proven-guilty attitude toward chemicals in general is
building up a lengthening history of damage and regret.  If we were watching
that history from the perspective of a different culture or planet, we would
surely wonder whether those crazy folks would ever stop doing chemistry
experiments on themselves and their world.
