85% of Tampons Contain Monsanto's 'Cancer Causing' Glyphosate

Glyphosate, a widely popular herbicide that has been linked to cancer by the World Health Organization's cancer research arm, was detected in 85 percent of cotton hygiene products tested in a preliminary study from researchers at the University of La Plata in Argentina.

Sixty-two percent of the samples also tested positive for AMPA (or aminomethylphosphonic acid), a derivative of glyphosate.

“Eighty-five percent of all samples tested positive for glyphosate and 62 percent for AMPA, which is the environmental metabolite, but in the case of cotton and sterile cotton gauze the figure was 100 percent,” Dr. Damian Marino, the study's head researcher.

According to Revolution News, the samples—which included gauze, swabs, wipes and feminine care products such as tampons and sanitary pads—were purchased from local supermarkets and pharmacies in the La Plata area.

The findings were presented last week at the third national congress of Doctors of Fumigated Towns in Buenos Aires.

“Eighty-five percent of all samples tested positive for glyphosate and 62 percent for AMPA, which is the environmental metabolite, but in the case of cotton and sterile cotton gauze the figure was 100 percent,” Dr. Damian Marino, the study's head researcher, told the Télam news agency (via RT.com). An English translation of the Télam report can be read here.

“In terms of concentrations, what we saw is that in raw cotton AMPA dominates (39 parts per billion, or PPB, and 13 PPB of glyphosate), while the gauze is absent of AMPA, but contained glyphosate at 17 PPB,” said Dr. Marino.

Dr. Medardo Avila Vazquez, president of the congress, said (via RT.com) that the result of this research is "very serious when you use cotton or gauze to heal wounds or for personal hygiene uses, thinking they are sterilized products, and the results show that they are contaminated with a probably carcinogenic substance.

“Most of the cotton production in the country is GM [genetically modified] cotton that is resistant to glyphosate. It is sprayed when the bud is open and the glyphosate is condensed and goes straight into the product.”

Glyphosate is the key ingredient in biotech giant Monsanto's Roundup, the most popular weedkiller in the U.S. “Roundup Ready” cotton, soy and corn crops have been genetically modified to withstand application of the herbicide.

In fact, farmers sprayed 2.6 billion pounds of Monsanto’s glyphosate herbicide on U.S. agricultural land between 1992 and 2012, according to the U.S. Geological Survey.

In 2015, the U.S. Department of Agriculture found that adoption of genetically modified-varieties, including those with herbicide tolerance, insect resistance or stacked traits, accounted for 94 percent of the nation's cotton acreage.

The graph below from the U.S. Department of Agriculture indicates an upward trend on the country's adoption of genetically modified soybean, corn and cotton.

Monsanto maintains the safety of their product, citing its approval from the U.S. Environmental Protection Agency, which "classified the carcinogenicity potential of glyphosate as Category E: 'evidence of non-carcinogenicity for humans.'"

Monsanto is also demanding a retraction of the World Health Organization's classification of glyphosate as a possible carcinogen.

This is not the first time that the chemical makeup of feminine care products has been put under the lens. A 2013 report by Women’s Voices for the Earth detailed how the feminine care industry sells products containing unregulated and potentially harmful chemicals, including preservatives, pesticides, fragrances and dyes.

This College Could Become the First 100% Renewable Campus in U.S.

As a growing number of U.S. cities make pledges towards 100 percent renewables, it's easy to forget that the entire state of Hawaii set this important benchmark three years ago when it mandated that all of its electricity must come from renewable sources no later than 2045.

To help the Aloha State meet this ambitious commitment, in 2015, the University of Hawaii (UH) and the Hawaiian Legislature set a collective goal for the university system to be "net-zero" by Jan. 1, 2035, which means the total amount of energy consumed is equal to the amount of renewable energy created.

Silver Nanoparticles in Clothing Wash Out, May Be Toxic

By Sukalyan Sengupta and Tabish Nawaz

Humans have known since ancient times that silver kills or stops the growth of many microorganisms. Hippocrates, the father of medicine, is said to have used silver preparations for treating ulcers and healing wounds. Until the introduction of antibiotics in the 1940s, colloidal silver (tiny particles suspended in a liquid) was a mainstay for treating burns, infected wounds and ulcers. Silver is still used today in wound dressings, in creams and as a coating on medical devices.

Study Finds Timely Emissions Reductions Could Prevent 153 Million Air Pollution Deaths This Century

One of the roadblocks to swift action on climate change is the human brain's tendency to focus on threats and stimuli that are an obvious and noticeable part of their everyday lives, rather than an abstract and future problem, as Amit Dhir explained in The Decision Lab.

Now, a study published in Nature Climate Change Monday shows that acting quickly to curb greenhouse gas emissions would also reduce the air pollution that is already a major urban killer, thereby saving millions of lives within the next 40 years.

Trump Administration Sells Oil and Gas Leases Near Utah National Monuments

The Interior Department on Tuesday is auctioning off 32 parcels of public lands in southeastern Utah for oil and gas development.

The Bureau of Land Management's (BLM) lease sale includes more than 51,000 acres of land near Bears Ears—the national monument significantly scaled back by the Trump administration last year—as well as the Hovenweep and Canyons of the Ancients monuments.

Katharine Hayhoe Reveals Surprising Ways to Talk About Climate Change

By Katie O'Reilly

Katharine Hayhoe isn't your typical atmospheric scientist. Throughout her career, the evangelical Christian and daughter of missionaries has had to convince many (including her pastor husband) that science and religion need not be at odds when it comes to climate change. Hayhoe, who directs Texas Tech's University's Climate Science Center, is CEO of ATMOS Research, a scientific consulting company, and produces the PBS Kids' web series Global Weirding, rose to national prominence in early 2012 after then-presidential candidate Newt Gingrich dropped her chapter from a book he was editing about the environment. The reason? Hayhoe's arguments affirmed that climate change was no liberal hoax. The Toronto native attracted the fury of Rush Limbaugh, who encouraged his listeners to harass her.

Kinder Morgan Pipeline Protest Grows: Arrests Include a Greenpeace Founder, Juno-Nominated Grandfather

By Andy Rowell

Just because you get older, it doesn't mean you cannot stop taking action for what you believe in. And Monday was a case in point. Two seventy-year-olds, still putting their bodies on the line for environmental justice and indigenous rights.

Early Monday morning, the first seventy-year-old, a grandfather of two, and former nominee for Canada's Juno musical award, slipped into Kinder Morgan's compound at one of its sites for the controversial Trans Mountain pipeline and scaled a tree and then erected a mid-air platform with a hammock up in the air.

The Grapes of Trash

German monk and theologian Martin Luther probably said it best: "Beer is made by men, wine by God." It's true—the world loves its wine. Americans, in fact, downed close to a billion gallons of it in 2016. But winemakers create a lot of waste when they produce all that vino, most of it in seeds, stalks and skins.

Why Mike Pompeo Could Be Even Worse for the Environment Than Rex Tillerson

By Kelle Louaillier

As Secretary of State, Rex Tillerson was one of the most blatant revolving-door cases in the Trump administration and a clear sign that Trump's government was of, by and for the fossil fuel industry. But make no mistake: Mike Pompeo could be far worse.
