Researchers Link Glyphosate to Shorter Pregnancies

Health + Wellness
The use of glyphosate has increased significantly since the introduction of genetically modified foods in the 1990s.

Researchers from Indiana University and University of California San Francisco have linked glyphosate exposure in pregnancy to shortened gestational length.

The new study, published in the journal Environmental Health, found that 93 percent of a study group of pregnant women in Indiana had detectable levels of the widely used and controversial herbicide in their urine. Those with higher levels delivered earlier compared to those with less or none.


The research was based on urine samples obtained from 71 pregnant women from nine counties in central Indiana, including a mix of rural, suburban and urban addresses, between 2015 and 2016. Typically, the length of human gestation is around 280 days, or 40 weeks. But the overall average gestational age of all 71 births in the study group was around 274 days, the researchers found. Two infants in the study were born premature, or less than 37 weeks of gestation.

Glyphosate was not correlated with other fetal growth indicators such as birth weight percentile and head circumference.

Shahid Parvez, the principal investigator of the study and an assistant professor at Indiana University, warned that babies born early can have health problems.

"There is growing evidence that even a slight reduction in gestational length can lead to lifelong adverse consequences," he said in a statement.

According to the study, the highest levels of glyphosate were found in women who lived in rural areas and in those who consumed more than 24 oz. of caffeinated beverages per day.

Glyphosate, the active ingredient in Monsanto's Roundup, is the world's most popular herbicide and likely the most contentious. Exposure to glyphosate has increased approximately 500 percent since 1994, when Monsanto introduced "Roundup Ready" crops that are genetically engineered to resist the weedkiller.

Use of glyphosate is heaviest in the Midwest due to corn and soybean production, as a press release for the new study noted.

The pervasiveness of glyphosate means it is regularly detected in the natural environment and in everyday foods, including cookies, crackers, popular cold cereals, chips and alcoholic beverages—and consequently–in human urine.

A number of experts have expressed concern over the public's increasing exposure to the chemical.

"One thing we cannot deny is that glyphosate exposure in pregnant women is real," Parvez said.

For the study, the researchers also collected drinking water samples from the participants' homes. They found that none of the drinking water samples had detectable glyphosate levels, meaning the women were unlikely to be exposed to the chemical from their drinking water.

"The good news is that the public drinking water supply may not be the primary source of glyphosate exposure, as we initially anticipated. None of the tested drinking water samples showed glyphosate residues. It is likely that glyphosate is eliminated in the water-treatment process," Parvez said.

"The bad news is that the dietary intake of genetically modified food items and caffeinated beverages is suspected to be the main source of glyphosate intake."

Parvez told Reuters that the association between caffeine intake and high glyphosate levels in urine was surprising.

"It makes sense to us since there are many different food products imported from southeast Asia and South America but we don't know what they contain," he said. "It indicates a need to think about these food products, such as coffee beans and other drinks that we import."

Monsanto dismissed the study and adamantly defended the safety of its product, telling Reuters, "Even at the highest reported levels of glyphosate exposure, the findings by Parvez et al do not indicate any adverse health outcomes, the gestation ranges reported by Parvez et al are well within the normal range of gestation lengths and the trace amounts of glyphosate reported in the urine samples are consistent with exposures that are well below the strict limits the Environmental Protection Agency (EPA) established to protect human health."

Scott Partridge, vice president of global strategy for Monsanto, added to Reuters, "When it comes to safety assessments, no other pesticide has been more extensively tested than glyphosate. In evaluations spanning four decades, the overwhelming conclusion of experts worldwide, including the EPA, has been that glyphosate can be used safely according to label instructions."

Parvez acknoweldged that the results of the study mandate further investigation. Besides the small number of participants, the average age of the women was 29 years and the majority were white.

"Although our study cohort was small and regional and had limited racial or ethnic diversity, it provides direct evidence of maternal glyphosate exposure and a significant correlation with shortened pregnancy," Parvez said.

"We are planning, contingent upon funding, to conduct a more comprehensive study in a geographically and racially diverse pool of pregnant women to determine if our findings are the same," he said.

The huge surge this year in Amazon deforestation is leading some European countries to think twice about donations to the Amazon Fund. LeoFFreitas / Moment / Getty Images

Ola Elvestrun, Norway's environment minister, announced Thursday that it is freezing its contributions to the Amazon Fund, and will no longer be transferring €300 million ($33.2 million) to Brazil. In a press release, the Norwegian embassy in Brazil stated:

Given the present circumstances, Norway does not have either the legal or the technical basis for making its annual contribution to the Amazon Fund.

Brazilian President Jair Bolsonaro reacted with sarcasm to Norway's decision, which had been widely expected. After an official event, he commented: "Isn't Norway the country that kills whales at the North Pole? Doesn't it also produce oil? It has no basis for telling us what to do. It should give the money to Angela Merkel [the German Chancellor] to reforest Germany."

According to its website, the Amazon Fund is a "REDD+ mechanism created to raise donations for non-reimbursable investments in efforts to prevent, monitor and combat deforestation, as well as to promote the preservation and sustainable use in the Brazilian Amazon." The bulk of funding comes from Norway and Germany.

The annual transfer of funds from developed world donors to the Amazon Fund depends on a report from the Fund's technical committee. This committee meets after the National Institute of Space Research, which gathers official Amazon deforestation data, publishes its annual report with the definitive figures for deforestation in the previous year.

But this year the Amazon Fund's technical committee, along with its steering committee, COFA, were abolished by the Bolsonaro government on 11 April as part of a sweeping move to dissolve some 600 bodies, most of which had NGO involvement. The Bolsonaro government views NGO work in Brazil as a conspiracy to undermine Brazil's sovereignty.

The Brazilian government then demanded far-reaching changes in the way the fund is managed, as documented in a previous article. As a result, the Amazon Fund's technical committee has been unable to meet; Norway says it therefore cannot continue making donations without a favorable report from the committee.

An Uncertain Future

The Amazon Fund was announced during the 2007 United Nations Climate Change Conference in Bali, during a period when environmentalists were alarmed at the rocketing rate of deforestation in the Brazilian Amazon. It was created as a way of encouraging Brazil to continue bringing down the rate of forest conversion to pastures and croplands.

Government agencies, such as IBAMA, Brazil's environmental agency, and NGOs shared Amazon Fund donations. IBAMA used the money primarily to enforce deforestation laws, while the NGOs oversaw projects to support sustainable communities and livelihoods in the Amazon.

There has been some controversy as to whether the Fund has actually achieved its goals: in the three years before the deal, the rate of deforestation fell dramatically but, after money from the Fund started pouring into the Amazon, the rate remained fairly stationary until 2014, when it began to rise once again. But, in general, the international donors have been pleased with the Fund's performance, and until the Bolsonaro government came to office, the program was expected to continue indefinitely.

Norway has been the main donor (94 percent) to the Amazon Fund, followed by Germany (5 percent), and Brazil's state-owned oil company, Petrobrás (1 percent). Over the past 11 years, the Norwegians have made, by far, the biggest contribution: R$3.2 billion ($855 million) out of the total of R$3.4 billion ($903 million).

Up till now the Fund has approved 103 projects, with the dispersal of R$1.8 billion ($478 million). These projects will not be affected by Norway's funding freeze because the donors have already provided the funding and the Brazilian Development Bank is contractually obliged to disburse the money until the end of the projects. But there are another 54 projects, currently being analyzed, whose future is far less secure.

One of the projects left stranded by the dissolution of the Fund's committees is Projeto Frutificar, which should be a three-year project, with a budget of R$29 million ($7.3 million), for the production of açai and cacao by 1,000 small-scale farmers in the states of Amapá and Pará. The project was drawn up by the Brazilian NGO IPAM (Institute of Environmental research in Amazonia).

Paulo Moutinho, an IPAM researcher, told Globo newspaper: "Our program was ready to go when the [Brazilian] government asked for changes in the Fund. It's now stuck in the BNDES. Without funding from Norway, we don't know what will happen to it."

Norway is not the only European nation to be reconsidering the way it funds environmental projects in Brazil. Germany has many environmental projects in the Latin American country, apart from its small contribution to the Amazon Fund, and is deeply concerned about the way the rate of deforestation has been soaring this year.

The German environment ministry told Mongabay that its minister, Svenja Schulze, had decided to put financial support for forest and biodiversity projects in Brazil on hold, with €35 million ($39 million) for various projects now frozen.

The ministry explained why: "The Brazilian government's policy in the Amazon raises doubts whether a consistent reduction in deforestation rates is still being pursued. Only when clarity is restored, can project collaboration be continued."

Alternative Amazon Funding

Although there will certainly be disruption in the short-term as a result of the paralysis in the Amazon Fund, the governors of Brazil's Amazon states, which rely on international funding for their environmental projects, are already scrambling to create alternative channels.

In a press release issued yesterday Helder Barbalho, the governor of Pará, the state with the highest number of projects financed by the Fund, said that he will do all he can to maintain and increase his state partnership with Norway.

Barbalho had announced earlier that his state would be receiving €12.5 million ($11.1 million) to run deforestation monitoring centers in five regions of Pará. Barbalho said: "The state governments' monitoring systems are recording a high level of deforestation in Pará, as in the other Amazon states. The money will be made available to those who want to help [the Pará government reduce deforestation] without this being seen as international intervention."

Amazonas state has funding partnerships with Germany and is negotiating deals with France. "I am talking with countries, mainly European, that are interested in investing in projects in the Amazon," said Amazonas governor Wilson Miranda Lima. "It is important to look at Amazônia, not only from the point of view of conservation, but also — and this is even more important — from the point of view of its citizens. It's impossible to preserve Amazônia if its inhabitants are poor."

Looming International Difficulties

The Bolsonaro government's perceived reluctance to take effective measures to curb deforestation may in the longer-term lead to a far more serious problem than the paralysis of the Amazon Fund.

In June, the European Union and Mercosur, the South American trade bloc, reached an agreement to create the largest trading bloc in the world. If all goes ahead as planned, the pact would account for a quarter of the world's economy, involving 780 million people, and remove import tariffs on 90 percent of the goods traded between the two blocs. The Brazilian government has predicted that the deal will lead to an increase of almost $100 billion in Brazilian exports, particularly agricultural products, by 2035.

But the huge surge this year in Amazon deforestation is leading some European countries to think twice about ratifying the deal. In an interview with Mongabay, the German environment ministry made it very clear that Germany is very worried about events in the Amazon: "We are deeply concerned given the pace of destruction in Brazil … The Amazon Forest is vital for the atmospheric circulation and considered as one of the tipping points of the climate system."

The ministry stated that, for the trade deal to go ahead, Brazil must carry out its commitment under the Paris Climate agreement to reduce its greenhouse gas emissions by 43 percent below the 2005 level by 2030. The German environment ministry said: If the trade deal is to go ahead, "It is necessary that Brazil is effectively implementing its climate change objectives adopted under the [Paris] Agreement. It is precisely this commitment that is expressly confirmed in the text of the EU-Mercosur Free Trade Agreement."

Blairo Maggi, Brazil agriculture minister under the Temer administration, and a major shareholder in Amaggi, the largest Brazilian-owned commodities trading company, has said very little in public since Bolsonaro came to power; he's been "in a voluntary retreat," as he puts it. But Maggi is so concerned about the damage Bolsonaro's off the cuff remarks and policies are doing to international relationships he decided to speak out earlier this week.

Maggi, a ruralista who strongly supports agribusiness, told the newspaper, Valor Econômico, that, even if the European Union doesn't get to the point of tearing up a deal that has taken 20 years to negotiate, there could be long delays. "These environmental confusions could create a situation in which the EU says that Brazil isn't sticking to the rules." Maggi speculated. "France doesn't want the deal and perhaps it is taking advantage of the situation to tear it up. Or the deal could take much longer to ratify — three, five years."

Such a delay could have severe repercussions for Brazil's struggling economy which relies heavily on its commodities trade with the EU. Analysists say that Bolsonaro's fears over such an outcome could be one reason for his recently announced October meeting with Chinese President Xi Jinping, another key trading partner.

Maggi is worried about another, even more alarming, potential consequence of Bolsonaro's failure to stem illegal deforestation — Brazil could be hit by a boycott by its foreign customers. "I don't buy this idea that the world needs Brazil … We are only a player and, worse still, replaceable." Maggi warns, "As an exporter, I'm telling you: things are getting very difficult. Brazil has been saying for years that it is possible to produce and preserve, but with this [Bolsonaro administration] rhetoric, we are going back to square one … We could find markets closed to us."
