New Evidence Establishes Dangers of Monsanto's Roundup Weed Killer

Title: "New Evidence of Dangers of Roundup Weedkiller"

New studies from both sides of the Atlantic reveal that Roundup, the
most widely used weed killer in the world, poses serious human health
More than 75 percent of genetically modified (GM) crops are engineered
to tolerate the absorption of Roundup; it eliminates all plants that are
not Genetically Modified.
Monsanto Inc., the major engineer of GMO crops, is also the producer of
Thus, while Roundup was formulated as a weapon against weeds, it has
also become a prevalent ingredient within most of our food crops.
Three recent studies show that Roundup, which is used by farmers and
home gardeners, is not the safe product we have been led to trust.
A group of scientists led by biochemist Professor Gilles-Eric Seralini
from the University of Caen in France found that human placental cells
are very sensitive to Roundup at concentrations even lower than those
currently used in agricultural application.
An epidemiological study of Ontario farming populations showed that
exposure to glyphosate, the key ingredient in Roundup, nearly doubled
the risk of late miscarriages.
Professor Gilles-Eric Seralini and his team decided to research the
effects of the Roundup herbicide on human placenta cells.
Their study confirmed the toxicity of glyphosate, as after only eighteen
hours of exposure at low concentrations, large proportions of human
placenta began to die.
Professor Gilles-Eric Seralini suggests that this may explain the high
levels of premature births and miscarriages observed among female
farmers using glyphosate/Roundup.
Professor Gilles-Eric Seralini's team further compared the toxic effects
of the Roundup formula (the most common commercial formulation of
glyphosate and chemical additives) to the isolated active ingredient,
They found that the toxic effect increases in the presence of Roundup
'adjuvants' or additives. These additives thus have a facilitating role,
rendering Roundup twice as toxic as its isolated active ingredient,
Another study, released in April 2005 by the University of Pittsburgh,
suggests that Roundup is a danger to other life-forms and non-target
organisms. Biologist Rick Relyea found that Roundup is extremely lethal
In what is considered one of the most extensive studies on the effects
of pesticides on nontarget organisms in a natural setting, Biologist
Rick Relyea found that Roundup caused a 70 percent decline in amphibian
biodiversity and an 86 percent decline in the total mass of tadpoles.
Leopard frog tadpoles and gray tree frog tadpoles were nearly eliminated.
In 2002, a scientific team led by Robert Belle of the National Center
for Scientific Research (CNRS) biological station in Roscoff, France
showed that Roundup activates one of the key stages of cellular division
that can potentially lead to cancer.
Robert Belle and his team have been studying the impact of glyphosate
formulations on sea urchin cells for several years.
The team has recently demonstrated in Toxicological Science (December
2004) that a "control point" for DNA damage was affected by Roundup,
while glyphosate alone had no effect.
"We have shown that it's a definite risk factor, but we have not
evaluated the number of cancers potentially induced, nor the time frame
within which they would declare themselves," Robert Belle acknowledges.
There is, indeed, direct evidence that glyphosate inhibits an important
process called RNA transcription in animals, at a concentration well
below the level that is recommended for commercial spray application.
There is also new research that shows that brief exposure to commercial
glyphosate causes liver damage in rats, as indicated by the leakage of
intracellular liver enzymes. The research indicates that glyphosate and
its surfactant in Roundup were found to act in synergy to increase
damage to the liver.
UPDATE BY CHEE YOKE HEONG
Roundup Ready weed killer is one of the most widely used weed killers in
the world for crops and backyard gardens.
Roundup, with its active ingredient glyphosate, has long been promoted
as safe for humans and the environment while effective in killing weeds.
It is therefore significant when recent studies show that Roundup is not
as safe as its promoters claim.
This has major consequences, as the bulk of commercially planted
genetically modified crops are designed to tolerate glyphosate (and
especially Roundup), and independent field data already shows a trend of
increasing use of the herbicide.
This goes against industry claims that herbicide use will drop and that
these plants will thus be more "environment-friendly." Now it has been
found that there are serious health effects, too.
Their story therefore aimed to highlight these new findings and their
implications to health and the environment.
Not surprisingly, Monsanto came out refuting some of the findings of the
studies mentioned in the article. What ensued was an open exchange
between Dr. Rick Relyea and Monsanto, whereby the former stood his
Otherwise, to my knowledge, no studies have since emerged on Roundup.

do start developing a resistance to it, which then requires more Round
