Heavy use of the world's most popular herbicide, Roundup, could be linked to a range of health problems and diseases, including Parkinson's, infertility and cancers, according to a new study.
true The peer-reviewed report, published last week in the scientific journal Entropy, said evidence indicates that residues of "glyphosate," the chief ingredient in Roundup weed killer, which is sprayed over millions of acres of crops, has been found in food.
Those residues enhance the damaging effects of other food-borne chemical residues and toxins in the environment to disrupt normal body functions and induce disease, according to the report, authored by Stephanie Seneff, a research scientist at the Massachusetts Institute of Technology, and Anthony Samsel, a retired science consultant from Arthur D. Little, Inc. Samsel is a former private environmental government contractor as well as a member of the Union of Concerned Scientists.
"Negative impact on the body is insidious and manifests slowly over time as inflammation damages cellular systems throughout the body," the study says.
We "have hit upon something very important that needs to be taken seriously and further investigated," Seneff said.
Environmentalists, consumer groups and plant scientists from several countries have warned that heavy use of glyphosate is causing problems for plants, people and animals.
The EPA is conducting a standard registration review of glyphosate and has set a deadline of 2015 for determining if glyphosate use should be limited. The study is among many comments submitted to the agency.
Monsanto is the developer of both Roundup herbicide and a suite of crops that are genetically altered to withstand being sprayed with the Roundup weed killer.
These biotech crops, including corn, soybeans, canola and sugarbeets, are planted on millions of acres in the United States annually. Farmers like them because they can spray Roundup weed killer directly on the crops to kill weeds in the fields without harming the crops.
Roundup is also popularly used on lawns, gardens and golf courses.
Monsanto and other leading industry experts have said for years that glyphosate is proven safe, and has a less damaging impact on the environment than other commonly used chemicals.
Jerry Steiner, Monsanto's executive vice president of sustainability, reiterated that in a recent interview when questioned about the study.
"We are very confident in the long track record that glyphosate has. It has been very, very extensively studied," he said.
Of the more than two dozen top herbicides on the market, glyphosate is the most popular. In 2007, as much as 185 million pounds of glyphosate was used by U.S. farmers, double the amount used six years ago, according to Environmental Protection Agency (EPA) data.

The herbicide used on genetically modified soy – Argentina’s main crop – causes brain, intestinal and heart defects in fetuses, according to the results of a scientific investigation.
BUENOS AIRES – The herbicide used on genetically modified soy – Argentina’s main crop – could cause brain, intestinal and heart defects in fetuses, according to the results of a scientific investigation released Monday.
Although the study “used amphibian embryos,” the results “are completely comparable to what would happen in the development of a human embryo,” embryology professor Andres Carrasco, one of the study’s authors, told Efe.
“The noteworthy thing is that there are no studies of embryos on the world level and none where glyphosate is injected into embryos,” said the researcher with the National Council for Scientific and Technical Research and director of the Molecular Embryology Laboratory.
The doses of herbicide used in the study “were much lower than the levels used in the fumigations,” and so the situation “is much more serious” that the study suggests because “glyphosate does not degrade,” Carrasco warned.
In Argentina, farmers each year use between 180 and 200 million liters of glyphosate, which was developed by the multinational Monsanto and sold in the United States under the brand name Roundup.
Carrasco said that the research found that “pure glyphosate, in doses lower than those used in fumigation, causes defects ... (and) could be interfering in some normal embryonic development mechanism having to do with the way in which cells divide and die.”
“The companies say that drinking a glass of glyphosate is healthier than drinking a glass of milk, but the fact is that they’ve used us as guinea pigs,” he said.
He gave as an example what occurred in Ituzaingo, a district where 5,000 people live on the outskirts of the central Argentine city of Cordoba, where over the past eight years about 300 cases of cancer associated with fumigations with pesticides have turned up.
“In communities like Ituzaingo it’s already too late, but we have to have a preventive system, to demand that the companies give us security frameworks and, above all, to have very strict regulations for fumigation, which nobody is adhering to out of ignorance or greed,” he said.
The researcher also said that, apart from the research he carried out, “there has to be a serious study” on the effects of glyphosate on human beings, adding that “the state has all the mechanisms for that.”
In the face of the volley of judicial complaints related to the disproportionate use of agrochemicals in the cultivation of GM soy, last February the Health Ministry created a group to investigate the problem in four Argentine provinces.
Argentina is the world’s third-largest exporter of soy.
