Reduce Health Risks With IPM…and Still Eliminate Pests
Pesticides
are not the only way to fight pests. Poison may be one tool, but it’s a
tool that we should use much less often, for our sakes and the sake of our
children. One of the biggest movements away from inordinate use of
pesticides is integrated pest management (IPM).
IPM does
not necessarily eliminate pesticide use, but it provides a much heavier
emphasis on a “holistic” approach to pest management that includes
nontoxic measures and less-toxic measures to eliminate pests or deter them
from settling down in a given area.
These
measures may include making structural changes that reduce pests’ access
through food, water and other entry points; choosing plants that are less
likely to encourage insects to proliferate; or finding natural biological
means of repelling pests.
Because
IPM emphasizes elimination of the underlying reasons for pest problems, it
is more effective than the conventional method, which relies only on
spraying pesticides to kill pests once they’ve already arrived.
IPM may
even be the most cost-effective way to manage pests over the long run.
According to the U.S. Environmental Protection Agency (EPA),
“…preliminary indications from IPM programs in school systems suggest
that long-term costs of IPM may be less than a conventional pest control
program.”
An IPM
program usually requires an initial economic investment, but over the long
term it yields significant savings by eliminating or reducing ongoing
chemical purchases. It also produces invaluable benefits that are harder
to measure economically, such as protecting students’ and staff
members’ health, reducing health-related problems, and possibly lowering
student absenteeism.
While IPM
won’t ensure that your local schools eliminate pesticide use, it can go
a long way toward improving kids’ health. Encourage your local schools
and the district as a whole to adopt IPM policies if they have not already
done so, and make use of IPM principles in your own home as well. (You can
visit the home safety section of our site to learn more about IPM in the
home, by clicking here.)
Various
states have adopted IPM and pesticide management policies for schools,
though they vary widely from place to place as to the extent of
protections and limitations. To find out what, if any, school pesticide
legislation your state has on the books, click here to view a
report online from the National Coalition Against the Misuse of Pesticides’
“Beyond Pesticides” Web site, or visit their site at
www.beyondpesticides.org/main.html.
In
addition, below are three Web sites that can help you (and your school
district too) learn about IPM in schools:

You
should also learn about the various types of pesticides your schools use
and what risks they may pose to your children. A list of some of the more
common pesticides used in schools is provided below. Note that Diazinon
and Dursban, both of which are on the list, are currently in the process
of a phase-out mandated by the EPA. Despite this, though, they are still
available for non-agricultural uses until 2004 from some manufacturers,
distributors and stores. So, some schools may still have access to, and
may be using, those two dangerous chemical products.

Products:

Health
Risks:

|
pyrethrins
|
Drione,
Pro-Control, CB-40, CB-80, Kicker, PT 175, PT 230 Tri-die, PT 565,
PT 505, ULD BP 100, ULD BP 300, Knockdown, Safer, Ortho Wasp,

Pyrethrins
seriously aggravate existing pollen allergies and adversely affect
male reproductive systems.
|
|
chlorpyrifos
|
Dursban,
Strikeforce, PT 270, others
|
Chlorpyrifos
can cause headache, dizziness, mental confusion and inability to
concentrate, blurred vision, vomiting, stomach cramps, uncontrolled
urination, diarrhea, seizure, birth defects, and multiple chemical
sensitivity. This insecticide has been linked to a nervous system
disorder resulting in weakness or paralysis of the extremities. In
children, acute exposure can cause seizures and mental changes such
as lethargy and coma. The Environmental Protection Agency (EPA)
recently ordered national phaseout of use of this chemical in all
non-agricultural products due to its harm to children’s health.
However, chlorpyrifos can still be purchased through December 2001
and existing stocks can be used indefinitely.

|
diazinon
|
KnoxOut,
TKO, Diazinon, others
|
Acute
symptoms include headache, muscle twitching, increased sweating
and/or salivation, muscle weakness, tremor and lack of coordination,
abdominal cramps, nausea, vomiting, loss of consciousness, blurred
vision, wheezing, coughing, and swelling in the lungs. EPA has also
ordered a phaseout of this chemical for non-agricultural use.
|
|
glyphosate
|
Roundup
|
Exposure
to glyphosate can irritate the eyes, skin, and upper respiratory
tract. Acute symptoms may include cardiac depression,
gastrointestinal pain, vomiting, and accumulation of excess lung
fluid.
|
|
hydramethylnon
|
Siege,
Maxforce products
|
Hydramethylnon
is typically used in bait or gel formulations, which, although
preferable to sprays, still pose exposure risk through inadvertent
ingestion or volatilization. A possible human carcinogen, this
insecticide has been shown to create adverse reproductive or
developmental effects.
