Mexico delays planned April 1 glyphosate ban

By Carey Gillam and Johnathan Hettinger

After standing firm for more than three years on plans to enact a ban on the weed killer glyphosate starting today, Mexican officials said they were delaying the ban.

Mexico is currently embroiled in a trade dispute with the United States over its unwillingness to accept genetically modified (GM) corn, typically altered to tolerate being sprayed with glyphosate and to manufacture toxins that repel pests, and Mexican officials have repeatedly stated that they consider both GM corn and glyphosate as threats to the health of the Mexican population as well as to the health of the environment.

But in a surprising reversal, less than a week before the ban was to kick in on April 1, government officials announced that glyphosate use could continue until other options for weed control are found. The move came amid reported heavy lobbying from powerful global agrochemical companies and pressure from US trade officials. Similarly, in 2019, Thailand backed down from a planned glyphosate ban after pressure from US officials and industry actors.

Fernando Bejarano, of the Pesticide Action Network in Mexico, said that the move comes after pressure from industry and US officials.

Mexico’s precaution on GM corn safety is justified

By Lucy Sharratt

A Presidential decree has banned the use of genetically modified (GM) corn for food in Mexico. But the governments of the United States and Canada are using the US-Canada-Mexico trade agreement (USMCA) to challenge Mexico’s actions.

The purpose of Mexico’s restrictions on GM corn is to safeguard the integrity of native corn from GM contamination and to protect human health. The purpose of the US and Canadian challenge is to defend the interests of the biotechnology industry. The US and Canada want to force Mexico to open its market to all genetically modified foods and seeds. Canada is supporting the US challenge (as a third party in the dispute) even though Canada does not export any corn to Mexico.

Mexico has the right to restrict the use of GM corn. The US argues that Mexico’s actions are not based on scientific principles, but the government has sufficient science to justify its precautionary policies.

Our organization, the Canadian Biotechnology Action Network, is a large network of farmer and environmental groups that has been monitoring the use of genetically modified organisms (GMOs) for over 15 years, and we support Mexico’s restrictions. We were one of two Canadian groups that were given permission to send expert comments on the risks of GM corn to the arbitration panel in this dispute, but in January, Canadian groups were uninvited at the request of the US government, supported by Canada, on the technicality that the dispute is just between the US and Mexico.

We published our analysis anyway, to show that Mexico’s ban is supported by the science. Research continues to find indicators of potential harm to humans from eating GM insect-resistant corn. The science also continues to warn of health impacts from exposure to the herbicide glyphosate, which is used in GM corn production.

Most GM corn plants are genetically modified to kill insect pests. The GM plants express a toxin from the soil bacteria Bacillus thuringiensis (Bt) that is known to harm the guts of specific types of insects but not others. Farmers have long used Bt as a spray to kill pests but the Bt toxins in GM crops are different from this natural Bt in structure, function, and biological effects. In fact, peer-reviewed studies across the scientific literature continue to find that Bt toxins in GM plants can harm insects (spiders, wasps, ladybugs, and lacewings, for example) that are not the intended targets.

Ohio PFAS class action lawyers slam US judges; seek rehearing

By Shannon Kelleher

A federal appeals court should grant a rehearing in a class action lawsuit filed against the makers of toxic PFAS chemicals after a panel of three federal judges disregarded legal precedent and misstated crucial facts in rejecting claims of liability alleged against PFAS makers, according to a petition filed by plaintiffs’ lawyers in the closely watched legal battle.

The request for rehearing comes after last month’s ruling by the Cincinnati, Ohio-based 6th US Circuit Court of Appeals, which reversed a lower court’s approval of the lawsuit brought on behalf of Ohio residents who want PFAS makers 3M, DuPont and others to pay for medical monitoring and studies that will analyze the health impacts of PFAS contamination the residents have been exposed to. The plaintiff’s attorneys have requested either a panel rehearing; a hearing before all judges of the court; or permission for the plaintiff to refile.

Lead plaintiff Kevin Hardwick worked as a firefighter for 40 years and used PFAS-containing foams at work. He alleges that ten companies, including chemical giants 3M, DuPont, and related companies, caused his blood -and the blood of other Ohio residents – to become contaminated with potentially dangerous levels of PFAS chemicals. The judges who rejected the allegations said in their opinion that Hardwick could not trace the chemicals in his blood back to the ten defendants, citing “the thousands of companies that have manufactured chemicals of this general type over the past half-century.”

In the filing by plaintiffs’ lawyers on Monday, the lawyers for the class action said the judges were factually wrong on multiple fronts, including stating that there are thousands of PFAS manufacturers. One of the PFAS toxins found in Hardwick’s blood is perfluorooctane sulfonic acid (PFOS). PFOS has only been made by defendant 3M, for instance, a fact not even disputed by 3M, the petition states. Another type of PFAS found in his blood was perfluorooctanoic acid (PFOA).

“Defendants do not dispute that they caused PFOA (and other PFAS) to be created and deposited into human blood. Nor do they dispute that that these toxins did not exist before Defendants created them,” the Hardwick petition states. The defendants additionally have been identified by the US EPA as “known makers” of PFOA, according to the petition for rehearing.

“What is going on?” Pregnant women living near farm fields show increased weed killing chemical in their urine

By Carey Gillam

Pregnant women living near farm fields show “significantly” increased concentrations of glyphosate weed killer in their urine during seasonal periods when farmers are spraying their fields with the pesticide, according to a new scientific paper published Wednesday.

The research team said the findings were concerning, given recent studies that have associated gestational exposure to glyphosate with reduced fetal growth and other fetal problems.

“If the developing fetus is especially vulnerable to glyphosate, it is critical to understand the magnitude and sources of exposure during this critical developmental period,” the new paper states. The authors include researchers from the University of California, Berkeley; the University of Washington; King’s College London; Boise State University; and the US Centers for Disease Control and Prevention (CDC).

The results were also considered somewhat surprising because none of the women studied worked with glyphosate or other pesticides or had a household member who worked with pesticides, said Cynthia Curl, associate professor at Boise State and lead author on the paper.

“What is going on? Is it drifting more than we think? Is it adhering to soil particles which then blow around and end up in people’s house dust? Is it drinking water? Until we figure that out we can’t suggest the right interventions,” Curl said.

Follow-up research will collect household dust and water samples to try to determine routes of exposure, Curl said.

Prior findings by the same research team found that pregnant women cut levels of glyphosate in their urine when eating an organic diet – unless they lived near farm fields.

Chemical found widely in the environment causes cancer, global experts determine

By Shannon Kelleher

A group of global scientific cancer experts this week classified a widespread chemical known as PFOA as carcinogenic to humans, confirming decades of research, and building on concerns about human and animal exposure to that chemical and to the larger class of manmade substances that are commonly known as “forever” chemicals because of their persistence in the environment. Separately, the experts deemed a related chemical called PFOS as possibly carcinogenic to humans.

The classifications, published Thursday in The Lancet Oncology, were determined by a working group of 30 experts from around the world through the International Agency for Research on Cancer (IARC), an arm of the World Health Organization (WHO). The experts convened in Lyon, France Nov. 7-14 to review published literature on the health risks of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). Both are types of per-and poly fluoroalkyl substances (PFAS).

“This latest action highlights and reaffirms the concerns we have been raising for decades that these man-made ‘forever chemicals’ present a serious threat to human health, mandating that appropriate steps be taken to prevent and address exposures,” said Rob Bilott, an environmental lawyer for the Ohio-based firm Taft Law who has spent over two decades exposing the dangers of PFAS chemicals.

In classifying PFOA as carcinogenic, the IARC scientists said they found “sufficient” evidence for cancer in experimental animals exposed to PFOA and “strong” evidence that the chemical affects gene expression and immune response in humans exposed to PFOA. They also found limited evidence for cancer in humans, identifying a link to renal cell cancer and testicular cancer.

The scientists said that the research shows PFOS is “possibly” carcinogenic to humans. They said they found strong mechanistic evidence that the chemical affects gene expression and immune response in exposed humans, along with several other key characteristics of carcinogens. They also found limited evidence linking PFOS to cancer in experimental evidence but ‘inadequate evidence’ linking it to cancer in humans.

It remains to be determined how, or if, the new classifications may impact thousands of lawsuits that are pending in US courts against PFAS makers DuPont and 3M. The companies have been sued by individuals as well as by drinking water utilities and municipalities over alleged harms tied to PFAS contamination.

On Monday, a US appeals court turned back a large class action lawsuit brought on behalf of Ohio residents, finding there was not sufficient proof that the companies caused the exposure alleged in the case. Lead plaintiff Kevin Hardwick, who worked as a firefighter for 40 years and used PFAS-containing foams, brought the suit in 2018, alleging that the companies caused his blood to become contaminated with potentially dangerous levels of PFAS chemicals. Hardwick asked for a panel of scientists to study the effects of PFAS in his body and for medical monitoring.

Rise in air pollution fuels antibiotic resistance, study suggests

By Grace van Deelen

Air pollution could be helping drive a rise in drug-resistant infections, which pose a dangerous threat to global public health, according to a new study.

The paper, published Monday in Lancet Planetary Health, concludes that particulate air pollution (PM2.5), which comes from burning fossil fuels for energy, industrial processes, and transportation, may be one of the largest contributors to the spread of antibiotic resistance worldwide. The link between the two phenomena has strengthened over time, according to the research.

“The benefits of controlling air pollution could be two-fold: not only will it reduce the harmful effects of poor air quality, it could also play a major role in combating the rise and spread of antibiotic-resistant bacteria,” said Hong Chen, the paper’s lead author and a professor of environmental science at Zhejiang University in China, in a statement.

The vast majority of the world’s population lives in areas where air pollution exceeds health standards set by the World Health Organization (WHO), meaning that they breath air containing high levels of pollutants, including PM2.5. Breathing polluted air raises the risk of premature death from heart disease, lung disease, stroke, and cancer affecting the lungs or airways. The Biden Administration has proposed multiple new policies to try to limit PM2.5, including tighter standards for soot pollution, new vehicle emissions standards, and improved reporting of air pollutants.

Shell hit with $10 mln penalty over air pollution

By Dana Drugmand

Pennsylvania state regulators have ordered a Shell subsidiary to pay nearly $10 million to resolve multiple air permit violations committed by the company’s new petrochemical facility located about 30 miles northwest of Pittsburgh.

The move comes amidst mounting frustration and outrage from area residents and environmental organizations over the plant’s release of hazardous chemicals and foul odors and disruptive flaring – a process designed to burn up invisible harmful hydrocarbons produced through plant operations – in recent months.

Shell’s 386-acre facility, located on the banks of the Ohio River in Beaver County, Pennsylvania near the town of Monaca, is the largest plastics production plant in the Northeast and Shell’s largest petrochemical facility outside of the Gulf Coast. The plant uses a process called “cracking” to convert the natural gas liquid ethane into the petrochemical ethylene, a building block for fossil fuel-derived plastic production.

Since Shell announced the startup of operations in November, the $6 billion plastics production facility has racked up 11 notices of violation – all pertaining to air quality – from the Pennsylvania Department of Environmental Protection (DEP), including four last week alone.

On Wednesday the state announced a consent order and agreement with Shell Chemicals Appalachia, the subsidiary operating the plant. Under the arrangement, the company has formally acknowledged its violations of the state’s Air Pollution Control Act and agreed to pay $4.9 million as a civil penalty plus another $5 million for projects to “benefit community environment and health.” Shell also agreed to make equipment repairs and take “all reasonable and feasible measures” to mitigate excess emissions, along with paying monthly civil penalties for future exceedance of emissions limits for the rest of 2023.

Monsanto accused of wrongly excluding non-US citizen from Roundup settlement

By Huanjia Zhang

(This story was originally published in Environmental Health News and is republished here with permission.)

Monsanto Co. and its corporate parent Bayer are facing a federal lawsuit for civil rights violations after they allegedly excluded a farmworker from a Roundup cancer settlement because of her immigration status.

According to the lawsuit, which was filed in the US District Court for the Western District of Virginia, plaintiff Elvira Reyes-Hernandez is a migrant farmworker who worked on Virginia tree farms between 2015 and 2018, during which she sprayed the herbicide Roundup regularly.

In 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) listed glyphosate, the active ingredient in Roundup, as “probably carcinogenic to humans.” Over the years, a wide body of scientific evidence has also pointed to glyphosate exposure as causing an increased risk of non-Hodgkin lymphoma.

Reyes-Hernandez was diagnosed with non-Hodgkin lymphoma in 2019 and subsequently sued Monsanto, claiming that Roundup exposure had a role in causing her cancer.

“Monsanto is very likely making calculated risks based on the characteristics of the people who are using their products,” said Katy Youker, an attorney for Lawyers’ Committee for Civil Rights Under Law and a co-counsel for the case.

By excluding non-US citizens from the settlement program, she said, Monsanto is effectively putting up a huge barrier for migrant farmworkers — most of whom do not have citizenship but are at the forefront of Roundup exposure — from seeking restitution.

This case could send an encouraging message to migrant and undocumented farmworkers who wish to bring legal action against the company. However, legal experts and farmworker advocates are still pessimistic about the prospect of them coming forward, especially when facing a myriad of hurdles and obstacles.

Biden misses the point on cancer fight

In President Biden’s state of the union address Tuesday night, he pledged his devotion to a fierce “fight against cancer,” invoking a heart-tugging story of baby “Ava,” who began battling kidney cancer at the age of 1.

Biden spoke of a reignited “Cancer Moonshot” search for a cure for cancers that are impacting far too many lives, and of measures to cut healthcare costs to make treating cancer more affordable. He outlined an ambitious goal to cut cancer death rates by at least 50% in the next 25 years, and to “turn more cancers from death sentences to treatable diseases, provide more support for patients and their families.”

But nowhere in his lengthy prime-time address did Biden speak of working to rein in the vast, virtually unchecked, flood of environmental chemical contaminants that scientists say cause cancer.

A new book scheduled for release in May written by journalist Kristina Marusic lays out in stark terms how already-staggeringly highly rates of cancer are sure to continue to climb if we don’t slash our exposure to the chemicals known to cause cancer.

The harsh statistics are detailed by Phil Landrigan, director of the Program for Global Public Health and the Common Good at Boston College, in the introduction to Marusic’s A New War on Cancer: The Unlikely Heroes Revolutionizing Prevention.

Landrigan writes: “From 1975 to to 2019, the number of new cancer cases per 100,000 Americans—the incidence rate—increased for multiple cancers. Incidence of multiple myeloma rose by 46%, incidence of non-Hodgkin lymphoma by 76%, and incidence of testicular cancer by 70%. In the same years, incidence of childhood leukemia increased by 35% and incidence of childhood brain cancer by 33%. These increases are far too rapid to be of genetic origin. They cannot be explained by better diagnosis.”
