Many
commercial applicators will tell you that pesticides will not
pose any harm
to you or the environment if instructions for their use are
followed carefully. However, several studies have shown that
certain pesticides are linked to many different cancers.
What
is the evidence of such a link?
In
a study by Tufts Medical Center in Boston, low doses of the
most commonly used pesticides were shown to cause breast cancer
cells to proliferate.
Researchers
have found that certain pesticides "mimic" the action of estrogen
when they accumulate in body fat, where they remained stored
for years. While the causes of breast cancer are not fully understood,
it is known that estrogen plays a big roll in the development
of this disease.
At
Mount Sinai Hospital in New York, researchers found high levels
of DDE, a residue of DDT, in blood samples of women who had
breast cancer.
After
banning two pesticides in 1978—Lindane and DDT—both of which
were used heavily in farming, Israel became the only country
in the world that reported a decrease in breast cancer.
Are
children at risk?
In
February 1995, a report published in the American Journal of
Public Health showed that children whose yards were treated
with insecticides had four times the risk of developing certain
cancers than those whose lawns were not treated. Children are
more exposed to pesticides than adults, since they are physically
closer to the ground and are more likely to play on lawns where
pesticides have been applied. In addition, young children usually
cannot read or understand warning signs.
Are
men at risk?
According
to the Pesticide Education Center in San Francisco, California,
numerous studies show an association between pesticide exposure
and certain types of cancer—such as prostate and testicular
cancer—in workers occupationally exposed to pesticides. Pesticides
that are classified as organochlorides create havoc in both
males and females by disrupting their endocrine systems. Some
researchers theorize that these "endocrine disrupters" may account
for the decline in sperm counts to a level in 1990 of nearly
50 per cent of what they were in 1930.
Are
animals at risk?
Reproductive
damage from pesticide exposure is evident in wildlife population.
In Apopka, Florida, male alligators that were exposed to the
pesticide Dicofol had drastically diminished genitals that left
them reproductively incompetent.
Do
the Environmental Protection Agency (EPA) and other government
agencies protect us from the dangers of pesticides?
Pesticides
are registered by the environmental protection agency, but not
all of them have been adequately tested. Many pesticides used
today were registered with the EPA before Congress strengthened
pesticide-testing requirements in 1978. As a result most other
pesticides used for lawn care have only been tested for a limited
number of the health effects which are of concern. EPA registration
is not a consumer product safety program.
What
can I do?
Fortunately,
there are many alternatives to reducing exposure and use of
toxic pesticides.
1.)
Increasing numbers of landscapers, gardeners, and arborists
is practicing integrated Pest Management—or IPM—. IPM uses the
least toxic approach first to control insect populations and
fungus. A careful evaluation of your own pesticide usage may
reveal some of it is unnecessary.
2.)
Careful sanitation may replace cockroach pesticides; insecticidal
soaps control aphids and other garden pests; and Bacillus thuringienis
(B.t.) can control caterpillars such as gypsy moths and worms
3.)
Physical controls such as hand weeding as well as traps and
barriers are effective in limiting pesticide use.
1.
Biological controls include releasing natural predators
such as praying mantises and ladybugs to control aphids and
spider mites. include releasing natural predators such as praying
mantises and ladybugs to control aphids and spider mites.
2. Adding bird feeders and birdhouses to increase the
number of birds on your property will help reduce gypsy moths
and Japanese beetles.
3. All of these non-toxic approaches help to reduce the
use of pesticides and make our environment a safer, healthier
place.
