The desire for the perfect lawn is leading millions of households across
the nation to expose children, pets, and water supplies to toxic pesticides
that threaten public health and the environment. The companies that make
these pesticides are not telling pesticide users how harmful they are to
people and the environment. The companies using these pesticides are not
telling their customers the full risks of using these pesticides. If you
have ever had pesticides applied to your lawn or have neighbors that have
pesticides applied to their lawns please read the article below.
Poison In The Grass:
The Hazards And Consequences Of Lawn Pesticides

As
the use of lawn chemicals and pesticides has grown, questions have arisen
regarding safety hazards and environmental consequences. This report gives
factual findings to help answer many of these concerns. Some of them may
seem shocking, since the chemical pesticide industry has made every effort
to keep this information from the public. Everything that follows in this
report is documented and supported by the U.S.Federal Government, private
agencies, and other experts.
Contrary to what lawn "care" companies
would like people to believe, herbicides (weed killers) and other
pesticides are not "magic bullets". They are broad spectrum
biocides, and by their very nature can harm organisms other than targeted
species. This includes homeowners and their families, neighbors, pets,
and all other forms of life. The pesticide industry downplays this
by claiming their chemicals are heavily diluted, but doesn't mention
the toxins are still extremely dangerous in small amounts. They also
are unwilling to mention all of what is in their mixtures. Many components
are classified as "inert", which allows them to be kept
hidden from the public and not listed on product labels. These are more
than just fillers or solvents. "Inert" does not mean "inactive" - some,
such as benzene and xylene, are more toxic than listed chemicals.(1,2)
Listed chemicals can be just as dangerous. They
include components of war-time
defoliants like Agent Orange, nerve-gas type insecticides, and artificial
hormones. Some the Federal Government has even prohibited from use
on it's own property. Many pesticides are not safe when dry. Water evaporates,
but most pesticides remain and continue to release often odorless
and invisible toxic vapors. In areas where lawn spraying is common,
they accumulate in a toxic smog throughout the entire season. Some pesticides
remain active for years after application. DDT is still showing up
in higher rates in women's breast milk than the government permits in cow's
milk.(4) Fat soluble pesticides accumulate over time in our bodies, then
are released at potentially toxic levels when illness or stress results
in our fat reserves being metabolised.A large portion of a woman's lifetime
exposure to such pesticides is released in the breast milk for her firstborn
child.(37)
It is a violation of U.S.Federal law to claim pesticides
are "safe when used as directed" since nothing can assure
safety.(2,3,5) (However, Agriculture Canada, the federal agency responsible
until recently for licensing pesticides in Canada, routinely used
this statement, adding for good measure that "most pesticides
are safer than table salt". Fortunately, pesticides in Canada
are now licensed by Health Canada.) Some pesticides labeled "bio-degradable" degrade
into compounds more dangerous than the original. Examples include
Mancozeb, which degrades into a substance that is an EPA-classified
probable carcinogen.(6) The pesticide industry also implies that "organic" means
safe and natural (for example, "Nature's Lawn"), knowing
that the term legally may be applied to any compound containing carbon
and hydrogen. ChemLawn and other lawn "care" companies and
manufacturers have often been sued for fictitious claims.(5-14) Many applicators
are just as conniving and deceitful, using statements like "absolutely
cannot harm children or pets" and "perfectly safe for the environment" to
mislead the public. The New York State Attorney General s Office sued
Dow Elanco chemical company when they claimed that Dursban shows "no
evidence of significant risk to the environment" when right on the
label is stated "this pesticide is toxic to birds and extremely toxic to
fish and aquatic organisms".(15) A few years later on May 2, 1995,
the EPA fined Dow Elanco for "failing to report to the Agency
information on adverse health effects (to humans) over the past decade
involving a number of pesticides, including chlorpyrifos (brand name
Dursban)". Most of the information came from personal injury
claims against Dow Elanco which the company had hidden from the EPA.
Now it is even being found that chlorpyrifos causes multiple sclerosis.(38)
Some companies have even made claims that their
products better the environment. "Funk" lawn
care of New York has coined the phrase "Growing A Better Environment" in
order to fool consumers into believing lawn chemicals pose no ecological
harm. Another states "a 50-by-50 foot lawn produces enough oxygen
to sustain a family of four." But this is only true with a plot
of land that has tall grass and no lawn care. Pesticides, lawnmower
fumes and common lawn care practices actually create a net destruction
of oxygen.(16)
The United States General Accounting Office,
the investigative arm of Congress, has also tried to alert the public
to lawn chemical dangers. GAO's undercover team noted many fictitious
claims by many in the lawn "care" industry.(35) Many included
illegal claims of product safety. Others were just deceiving, such
as the ChemLawn claim that a child would have to ingest ten cups of
treated grass clippings to equal the toxicity of one baby aspirin.
In fact, the real danger is not that people will be grazing the lawn
but that most poisonings come from inhaling pesticide residues or absorbing
them through the skin.(6,7,10)
Most do-it-yourselfers are just
as ignorant when it comes to proper protection and safety precautions.
Studies show most don't even look at the warnings on their toxins.
They don't wear gloves, goggles, or protective clothing to decrease
exposure. Worse, many don't keep people off the contaminated area
after chemicals are applied. Homeowners commonly use up to ten times
as much pesticides per acre as farmers.(7,17) A Virginia Tech study
for the state legislature found that most homeowners have no idea how much
nitrogen they use when fertilizing and that they apply chemicals in ways
that damage water supplies.(18)
Pesticides drift and settle
during application. In the Antarctic ice pack alone there are 2.4
million pounds of DDT and its metabolites from years past.(26) Pesticides
engulf the home and are easily tracked inside, readily inhaled and
absorbed through the skin. They do harm by attacking the central nervous
system and other essential organs. Symptoms of pesticide poisoning
are often deceptively simple, commonly mis-diagnosed as flu or allergies.
They include, but are not limited to, headaches, nausea, fever, breathing
difficulties, seizures, eye pains, vomiting, cramps, diarrhea, sore
nose, tongue, or throat; burning skin, rashes, coughing, muscle pain, tissue
swelling, blurred vision, numbness and tingling in hands or feet, incontinence,
anxiety, irritability, sleep disorders, hyperactivity, fatigue, dizziness,
irregular heartbeat, high blood pressure, spontaneous bleeding, and
temporary paralysis. Long-term consequences include lowered fertility,
birth defects, miscarriages, blindness, liver and kidney dysfunction,
neurological damage, heart trouble, stroke, immune system disorders,
menstrual problems, memory loss, suicidal depression, cancer, and
death. The National Academy of Sciences reports that at least one out of
seven people are significantly harmed by pesticide exposure each year.(3)
Increasingly, reports from many people around the country are "beginning
to link feeling terrible with the fact the neighbors had the lawn
sprayed the day before", notes Catherine Karr, a toxicologist for
the National Coalition Against The Misuse Of Pesticides.(7) Unfortunately, except
for industrial accidents, tests for pesticide poisoning are rarely performed,
partially because they are expensive. Doctors also attribute them
to stress, allergies, influenza, or an overactive imagination.(3)
Many
Americans are developing Multiple Chemical Sensitivity (MCS), a bizarre
and extremely disabling condition. In 1979, the Surgeon General issued
a report stating "There is virtually no major chronic disease to which
environmental factors do not contribute, directly or indirectly." Indeed,
people today are exposed to synthetic chemicals at levels unmatched at
any time throughout human history. Washington Post staff writer Michael Weiskopf
noted in a February 10, 1990 article that "hypersensitivity to low levels
of toxic chemicals (MCS) is a serious and growing medical problem, threatening
to cause significant economic consequences by disabling large numbers
of otherwise healthy people." MCS is a result of the destruction of the
body's ability to tolerate and synthesize chemicals after exposure to toxic
substances. Victims develop extreme reactions now not only to lawn pesticides
but also hair sprays, perfumes, soaps, formaldehyde, and many other
common household products.(5,36) Many victims include former lawn pesticide
applicators and users, their families, and children.
Sharon
Malhorta, a registered nurse from Pittsburgh, would get so sick from lawn
and tree spraying that she had to leave her home every spring. Otherwise
she would suffer headaches, paralysis in her hands and feet, and muscle
seizures. Repeated exposure caused blurred vision, speech difficulties,
and severe stomach cramps. Her husband, a doctor, suspected early
on her symptoms were the result of nerve damage from organophosphates,
which are widely used nerve-gas type insecticides, like Diazinon.
After questioning lawn companies about their products he was told they
were "practically nontoxic", registered by the EPA, and not harmful
to people or pets. He later discovered that the chemicals his wife
was exposed to were in fact neurotoxins, and was shocked to discover
there were surprisingly few EPA studies on their health effects.(19)
Karen James, a Michigan postal worker, successfully
sued ChemLawn in 1988. While
walking past one of their trucks, a hose ruptured and she was drenched
with chemicals. The employee told her not to worry, that only fertilizers
were in the spray. But soon after she became seriously ill, and her
eyes and skin burned. When her symptoms of fatigue, vomiting, diarrhea, and
reduced vision didn't clear up, her doctor called ChemLawn to find out what
chemicals she had been exposed to. He was told no pesticides had been involved,
but after tests on Karen s body tissue detected high levels of Dursban,
ChemLawn admitted the truck contained pesticides. Many other suits against
lawn companies are settled out of court. Frequently the settlement restrains
the victim from talking about the incident, so the public is not informed.(19)
For the price of green lawns, children are also
being poisoned. In 1985 a married
couple in Sarasota, Florida, felt pressured by their neighbors to get
their lawn treated. They hired a company, never thinking their 2-year-old
daughter would be jeopardized. The company declared the yard would
be safe about an hour after the chemicals were applied. However, soon after
playing barefoot on the grass, the couple's daughter developed a rash all
over her body, her urine turned dark brown, and she ran a high fever. Her
doctor prescribed antibiotics, but her condition grew steadily worse. Her
hands and feet swelled to twice normal size, blistered, and peeled. Her lips
turned black and bled. Years later she is still permanently prone to headaches
and has 40% hearing loss in her right ear.(19)
Barry and Jackie
Veysey believe lawn chemicals were responsible for the death of their
baby son. Barry was a professional turf master, and the chemicals
he worked with may have mutated his sperm or poisoned the infant in
utero. Every time Jackie washed her husband's uniforms, the chemicals may
have been absorbed through her skin and permeated the placenta. The child
was born with a severe and fatal type of dwarfism. Jackie held her son
only once before he died due to massive failure of his underdeveloped organs.(19)
Kevin Ryan from Arlington Heights, Illinois, feels
like a prisoner in his home. "I
can't even play in my own yard because the neighbors spray their lawns
and trees", he says. Kevin suffered routine chemical exposure as a toddler
from lawn spraying, and now suffers nausea, irritability, fatigue, and
loss of memory whenever pesticides are nearby. His family moves to Colorado
every spring and fall, the peak spraying times of the year, to keep
him safe.(19,20)
In 1986, Robin Dudek of Hamburg, New York
pulled the garden hose off her lawn and used it to fill a wading pool
for her daughters Amanda, 3, and Kristen, 2. Earlier her lawn had
been sprayed with chemicals. When Amanda started drinking from the
hose, she began to scream that the water was burning her. Then Kristen
began crying and screaming as well. Robin took the children inside
and noticed burn marks on both of them, as well as the smell of chemicals
on Amanda's breath. The girls later suffered from fevers, swollen
eyes, and blisters the size of grape clusters around their necks.(19)
Christina Locek was a professional ice skater and
pianist before her health was
destroyed in 1985, when her neighbor s lawn was sprayed with pesticides.
Her cat and dog died that same day, and she suffers headaches, partial
paralysis, vision loss, and blood disorders.(21) Former Navy Lieutenant
George Prior developed a fever, headache, and nausea after playing
on a golf course treated with Daconil. It was later discovered he was
suffering from toxicepidermal necrolysis, which causes skin to fall off in
sheets and massive organ failure. Prior died soon after.(6,8)
According
to the EPA, 95% of the pesticides used on residential lawns are possible
or probable carcinogens.(3,22) In 1989 the National Cancer Institute
reported children develop leukemia six times more often when pesticides
are used around their homes.(3,22) The American Journal of Epidemiology
found that more children with brain tumors and other cancers had been
exposed to insecticides than children without.(3) Studies by the National
Cancer Society and other medical researchers have discovered a definite
link between fatal non-Hodgkins Lymphoma (NHL) and exposure to triazine
herbicides (like Atrazine), phenoxyacetic herbicides (2,4-D), organophosphate
insecticides (Diazinon), fungicides, and fumigants; all of which have
uses as lawn chemicals. This may be an important contributing factor
to the 50% rise in NHL over the past ten years in the American population.
Studies of farmers who once used these pesticides found alarmingly
high numbers of NHL, especially in those who didn't wear protective
clothing. This latest finding also proves the theory that most danger
from pesticides comes through dermal absorption, not ingestion.(23) A
University of Iowa study of golf course superintendents found abnormally high
rates of death due to cancer of the brain, large intestine, and prostate.(4)
Other experts are beginning to link golfers, and non-golfers who live
near fairways, with these same problems.(8,24)
Documented cases
of pesticides in groundwater wells are suspect for cancer clusters
showing in many towns. In 1989, drinking water in at least 38 states
was known to be contaminated.(3) After the herbicide Dacthal was applied
to Long Island golf courses, it was detected in drinking water wells
at levels twenty times the State's safety limits. The water also contained
a dioxin that is a highly toxic by-product of Dacthal(8,19). The New
York State Attorney General sued the manufacturer in 1989 to investigate
the contamination and develop a treatment program, since ground water
is the main source of drinking water for Long Island. Twenty-two other
pesticides have been found in the water so far. However, there is still
no requirement or systematic program designed to test for drinking water
contamination.(3,25) As Michael Surgan, Ph.D., Chief Environmental Scientist
for the New York State Attorney General, and an advocate for responsible
pesticide use, puts it, "If you buy the notion that we have to accept
a certain amount of risk from pesticides to safeguard the food supply,
that's one thing, he notes. But with lawns, people are applying carcinogens
simply for the sake of aesthetics. That's got to change".(4)
Pesticides
and chemical fertilizers are becoming some of the worst water pollutants
in America. Discharges into San Francisco Bay from the central valley
of California are estimated at almost two tons per year.(26) Phosphorous
levels in some Maryland streams have doubled since 1986. And an EPA
study found potentially harmful levels of nitrate from chemical fertilizers
in drinking water wells nationwide. This can cause blue-baby syndrome
, an oxygen-depriving condition in infants that can be fatal.(18) Environmental
impacts are also devastating. Ward Stone, a DEC wildlife pathologist,
has long studied bird kills from pesticides that were used according
to regulation. Documented cases of owls, mourning doves, sparrows,
blue birds, and many other songbirds killed by lawn chemicals are on
the rise. Waterfowl like Canadian geese, mallards, wood ducks, and others
have suffered even worse. In 1984 there were 700 brant found dead on a
Long Island country club after it was sprayed with Diazinon.(8,27) Pesticide
exposure causes shivering, excessive salivating, grand mal seizures,
wild flapping, and sometimes screaming according to U.S. Fish and Wildlife
Service volunteer Diana Conger. Ward Stone likens these birds to miners'
canaries, foreshadowing serious harm to humans from chemical build-up
in the environment.(28)
Most people seriously overestimate
the amount of protection given them by governments regarding pesticide
safety. Congress found that 90% of the pesticides on the market lack
even minimal required safety screening.(3) Of the 34 most used lawn
pesticides, 33 have not been fully tested for human health hazards.(4)
If any tests are done, they are performed by the chemical manufacturers,
not the EPA. "If a chemical company wanted to, they could start
with a desired conclusion, and skew the data, and the EPA would never
know", notes David Welch, an entomologist with the EPA's Office of Pesticide
Programs. Welch did a random sampling of 15 pesticide files and found
13 without proper reviews.(19) One third of the most commonly used lawn
pesticides were illegally registered for use. Despite the fact executives
of Industrial Bio- Test labs were given jail terms for faking pesticides
tests, the chemicals are still on the market.(3) Shortages in funding,
personnel, and interference from business has slowed re-evaluation of
these chemicals.(25) Even when the EPA does refuse a pesticide registration,
the manufacturer often files a lawsuit, which keeps the chemical on
the market.(19) Jay Feldman, coordinator of the National Coalition
Against the Misuse of Pesticides, is well aware of this. "The EPA should
be called the IPA- the Industry Protection Agency", he charges. The chemical
industry is extremely powerful, and wraps the EPA in red tape. It is
also essential to understand that by law pesticide registration in the U.S.A.
is not a consumer safety program.(9) According to Congress, the EPA does
not have testing and assessment guidelines specifically for lawn use.(25)
EPA has admitted in court that pesticide registration does not ensure
product safety. Rather, it is a balancing act of costs and risks.(1-5,7-9,15,22)
Most lawn pesticides were registered before 1972, when more stringent
restrictions took effect under the revised Federal Rodenticide and
Fungicide Act. They were never tested for many human health hazards
like carcinogenicity, neurotoxicity, and environmental dangers. Most,
as previously stated, have yet to be re-evaluated, yet remain on the market.
Read the labels on many lawn pesticide products,
sprayed by lawn companies or
sold in stores, and you will find one or more of the following: 2,4-D, Captan,
Diazinon, Dursban, Dacthal, Dicamba, and Mecocrop. Each was registered
without full safety screening. 2,4-D is an artificial hormone that
has become a synonym for "dangerous pesticide", but dermal absorption of
mecoprop is far more dangerous, and dicamba is much more persistent in the
environment - a mixture of these three is usually used, not 2,4-D alone.
Diazinon has been banned for use on golf courses and sod farms due to
massive waterfowl deaths but is still widely used on lawns and gardens. It
is an organophosphate which disables the nervous system by blocking enzymes
essential for nerve impulse transmission.
People can protect
themselves and their families by knowing the facts. If having grass
that looks more like Astroturf than living plants still seems essential,
it doesn't have to come with pesticides but is possible with products
or programs that are organic and natural. This list of alternatives
continues to grow, and they are safer, cheaper, and often work better
than pesticides.(3,5) Ringer Corporation vice president Fred Hunt markets
natural fertilizers and microbes that kill pests. "We just don't think
a lot of these chemicals are necessary for aesthetic use on homeowners'
lawns", he reveals.(7) Chemicals add salt to the soil and kill beneficial
nitrogen-fixing microorganisms that provide necessary nutrients for
grass, turning a lawn into a junkie.(29) Each quick fix of green creates
a dependence for the next. Synthetic fertilizers kill earthworms and
other organisms that aerate soil, causing it to compact and kill grass plants.
Inorganic nitrogen-based fertilizers also promote the sprouting of weeds.(30)
Compounds in chemical fertilizers also acidify the soil and aid in
breeding of some insects. Lawns need a soil pH between 5.6 and 7 or else they
turn pale and thin out. Additional doses of chemicals will only make matters
worse.(31,32) Recycling grass clippings saves money, reduces waste, and
according to Lawn Institute Director Eliot C. Roberts is equivalent to three
applications of fertilizer a year without unhealthy chemicals and their
side-effects. Natural fertilizers are also better because they are time
released, allowing grass to grow slower and tougher, requiring much less
care.
Insects have been best controlled by other insects
for millions of years, and the lawn is no exception. Insecticides often
kill more beneficial insects than problem ones. Once the natural balance
is destroyed, continued reliance on insecticides will occur. This
is also true of weed killers. When a crabgrass stand is killed with
an herbicide, there will still be thousands of seeds ready to start
anew.(31) In the long run, pesticides can actually help the very pests
they target by also killing their predators, and their use becomes
self-perpetuating. Until a natural balance is restored, more and more
will have to be spent each year on chemicals, and resistant pests
may also invade. Using alternative strategies will bring better results
and be kinder to the environment. Integrated Pest Management gives
simple, long-lasting solutions which require no chemicals, much less money,
and much less time and effort. Many alternatives not explored here can
be found in the books and articles listed at the end of this report. What
makes a plant a "weed" is often only a matter of opinion. For instance,
it was once a sign of prestige to have clover in a lawn. Their flowers
and silky green leaves were once prized by homeowners, as was their natural
production of nitrogen fertiliser, and clover seed was sold by the bushels,
alone or mixed with grass seed. It wasn't until a chemical company discovered
a pesticide that killed clover but not always grass and launched an
enormous advertising campaign that clover became no longer fashionable. As
a result, people today ignore its fine qualities, even though throughout the
1950s it was "common as bluegrass".(33)
A growing
list of over 9,000 Americans are participating in the National Wildlife
Federation Backyard Wildlife Habitat program. By growing tall grasses,
they attract a dazzling array of wildflowers, butterflies, and birds,
creating habitats that are the aesthetic match of any manicured lawn.
Suggestions on what to plant to best attract wildlife can be obtained from
the Fish & Game Department of any state in the country.(34)
The
lawn pesticide industry is a very recent creation by chemical firms to expand
the market for aging farm chemicals. These products are not necessary
for use on lawns and pose serious ecological and human health risks
that outweigh any benefits they offer. Integrated Pest Management strategies
offer alternatives that work better and have less harmful effects.
Proper legislation to protect the public regarding pesticide use is
still seriously insufficient.(35) Therefore, the responsibility rests on the
public to be the ultimate judge of what the acceptable levels of risk will
be for their families and environment.(4)
