LA County accuses Pepsi and Coca-Cola of lying to consumers, worsening plastic pollution

By Douglas Main

Los Angeles this week sued PepsiCo and Coca-Cola for allegedly deceiving consumers and playing a “significant role” in a plastic pollution crisis that harms wildlife and poses a risk to human health.

The lawsuit, filed Wednesday in Los Angeles Superior Court, claims that the two global beverage and food companies are the “top plastic polluters in the world” and have engaged in a disinformation campaign designed to make consumers falsely believe that purchasing their products in single-use plastic bottles is an “environmentally responsible choice.”

“Coke and Pepsi need to stop the deception and take responsibility for the plastic pollution problems [their] products are causing,” Los Angeles County Board Chair Lindsey Horvath said in a statement.

Neither PepsiCo nor Coca-Cola immediately replied to requests for comment.

However, William Dermody, a spokesperson for American Beverage, which represents the non-alcoholic beverage industry in the U.S., wrote in a statement that “the allegation that our packaging is not and will not be recycled is simply not true.” Dermody added that “our bottles are designed to be recycled and remade and can include up to 100% recycled plastic.”

The suit is one of a growing number of cases where governmental bodies are pursuing legal means to address environmental problems relating to plastic.

High levels of hazardous heavy metals found in products used to fight wildfires

By Douglas Main

A new study shows that sprays and retardants used to fight wildfires contain surprisingly high levels of toxic heavy metals, a “disturbing” finding at a time when wildfires are generally getting worse.

The paper, published October 30 in the journal Environmental Science & Technology Letters, found that each of 14 fire suppression products examined contained at least eight of the ten heavy metals tested for, including chromium, cadmium, lead, and arsenic. Most of these metals or their derivatives are highly toxic, and known to cause a long list of diseases, including cancer.

All have been approved for use by the US Forest Service, which did not respond to a request for comment.

The findings raise questions about the ecological and human health impact of spraying large quantities of these materials over huge tracts of land in the western United States, according to study lead author Daniel McCurry, an environmental chemist at the University of Southern California.

McCurry and colleagues became interested in investigating these products’ chemistry as wildfire severity has increased in recent years and news reports showed these being used widely throughout California and other western states.

Wildfires have generally become more intense and widespread in recent years and decades, an expected outcome of human-caused climate change and land management practices. A total of just under 8 million acres have burned so far this year in the United States, a 24% increase over the 10 year average. Research suggests wildfires will get more severe and burn more acres in coming decades.

Agricultural chemicals are more toxic to insects than previously thought

By Douglas Main

New research provides evidence that chemicals used in farming may be more harmful to insects than previously thought, contributing to worldwide declines in important species.

In a wide-ranging, first-of-a-kind study published October 24 in the journal Science, scientists found that extremely small, sublethal concentrations of over 580 insecticides, herbicides, fungicides and other chemicals can have serious negative impacts on the behavior and subsequent survival of certain insects. The scientists tested some of the chemicals on fruit fly larvae, mosquitoes, and butterflies.

The results were “very shocking,” said study co-author Justin Crocker, a researcher with the European Molecular Biology Laboratory in Heidelberg, Germany.

The study bolsters the case that agrochemicals play a big role in plummeting populations of insects, a phenomenon that can gravely harm food production since certain insects are needed to pollinate key food crops.

In the paper, researchers exposed 75 fruit fly larvae to three concentrations of 1,024 different agrochemicals. The smallest level tested (2 micromoles) is well within the range found in the real world; for example, it’s not uncommon to find this concentration of the herbicide glyphosate in streams near crop fields.

After only 16 hours of exposure, they transferred the insects to vials containing chemical-free food, and filmed their behavior. More than half of these substances caused discernible changes in the behavior of developing insects.

Pesticides found in 80% of air samples from California farm communities

By Shannon Kelleher

Almost 80% of air samples collected last year in California’s four most agriculture-intensive communities contained pesticide residues, though the concentrations were “unlikely to be harmful to human health,” according to a recently released state regulatory report.

The California Department of Pesticide Regulation (CDPR) collected 207 air samples at stations in Oxnard, Santa Maria, Shafter and Watsonville once a week throughout 2023, finding at least one of the 40 pesticides they tested for in 163 of the samples, according to the results.

The monitoring stations detected a total of 19 different pesticides in the air samples, including the herbicide pendimethalin and the fumigant 1,3-dichloropronene (Telone), which have both been linked to cancer.

These chemicals and others detected by CDPR have also been linked to nausea, shortness of breath, and eye and respiratory irritation.

Despite being banned in 34 countries, Telone is the third-most heavily used pesticide in California, and CDPR has been criticized for failing to implement regulations that adequately protect mostly Latino farmworkers from the chemical.

The samples were all collected on school grounds, raising concerns among environmental and health advocates about safety risks for children and other vulnerable community members.

“The latest air sampling results continue to show pesticides sprayed on fields drift off site and contaminate the air nearby, a serious concern for those who live, go to school or work near farm fields,” Alexis Temkin, a senior toxicologist at the Environmental Working Group (EWG), said in a press release.

EPA cancels pesticide shown to be harmful to unborn babies

By Carey Gillam

Citing a need to protect the unborn babies of pregnant women, the US Environmental Protection Agency (EPA) on Tuesday banned a pesticide used to kill weeds on farms, golf courses and athletic fields.

The action comes after years of mounting scientific evidence of the dangers posed by exposure to the chemical dimethyl tetrachloroterephthalate, also known as DCPA or Dacthal.

“With the final cancellation of DCPA, we’re taking a definitive step to protect pregnant women and their unborn babies,” Michal Freedhoff, assistant administrator for the EPA Office of Chemical Safety and Pollution Prevention, said in a press release. “The science showing the potential for irreversible harm to unborn babies’ developing brains, in addition to other lifelong consequences from exposure, demands decisive action to remove this dangerous chemical from the marketplace.”

The agency said “robust studies” demonstrated “thyroid toxicity,” and said that unborn babies whose pregnant mothers are exposed to DCPA could experience changes to fetal thyroid hormone levels. Such changes are “generally linked to low birth weight, impaired brain development, decreased IQ, and impaired motor skills later in life, some of which may be irreversible,” the EPA said.

DCPA was registered to control weeds in both agricultural and non-agricultural settings, but has largely been used to control weeds in fields growing crops such as broccoli, brussels sprouts, cabbage and onions.

Bayer’s new Roundup products appear more toxic than prior formulations, new report asserts

By Carey Gillam

New types of Roundup weed killing products marketed to US consumers contain chemicals that pose greater health risks to people than prior formulations suspected of causing cancer, according to an analysis by an environmental health advocacy group.

Friends of the Earth (FOE) reported Tuesday it found four chemicals have recently been added to Roundup products that have been scientifically shown to cause a variety of health problems, including reproductive defects, kidney and liver damage, cancer, and neurotoxicity.

The analysis comes after the agrochemical company Bayer pledged that it would remove glyphosate from its popular Roundup herbicide products sold for residential lawn and garden use starting in 2023.

Bayer, which bought Monsanto in 2018, made the change to try to curtail the filing of future litigation as it battles thousands of lawsuits filed against Monsanto by cancer patients who claim they developed non-Hodgkin lymphoma from using Monsanto’s Roundup and other glyphosate-based herbicides.

But FOE said it found the chemicals used in the new Roundup formulations are, on average, 45 times more toxic to humans experiencing chronic exposure than glyphosate-based Roundup. The chemicals were roughly four times more acutely toxic, the group said.

Notably, all four of the added chemicals pose greater risk of long-term and/or reproductive health problems than does glyphosate, based on the Environmental Protection Agency’s (EPA) evaluation of safety studies, FOE said.

Of the four chemicals found in the products – diquat dibromide, fluazifop-P-butyl, triclopyr, and imazapic – the “worst offender”, according to FOE, is diquat dibromide. It is 200 times more toxic than glyphosate when exposure occurs over a long period of time, the group said, and is banned in the European Union. It is 27 times more toxic in acute exposures, the group said.

Kendra Klein, FOE deputy director for science and an author of the report, said the Environmental Protection Agency (EPA) should be providing stronger oversight.

“People need to realize that the EPA has long put the profits of companies like Bayer ahead of their health when it comes to pesticides,” Klein said. “And now, they’ve allowed Bayer to quietly swap out the chemicals in Roundup, making it far more toxic to people’s health, without changing the packaging or warning consumers of the increased risks.”

Running dry – US Army base under fire for high water use in drought-stricken Arizona

By Carmela Guaglianone

The San Pedro River, nestled in southeastern Arizona’s San Pedro Valley just north of the US-Mexico border, is one of the last undammed rivers in the Southwest and is considered a biodiversity hotspot. Lined with cattails, willows and cottonwoods, the marshy waterway shelters hundreds of diverse bird species, including many considered endangered and protected by federal law.

The area is also home to the Fort Huachuca US Army base, which has been heralded as an example of the military’s efforts to become more environmentally conscientious due to its use of solar power and other “green” initiatives.

Ten years ago, Fort Huachuca forged a plan to achieve “net-zero” by 2025. But today, that goal has been largely abandoned, and an expanding group of critics says the installation’s well-meaning conservation efforts are falling short, and the Army instead is posing a dire threat to a protected conservation zone as a result of the base’s rampant pumping of precious groundwater.

The Army and the nearby municipalities whose residents rely on the base for employment, are the most prolific groundwater users, withdrawing an estimated 10,000 acre feet per year, according to a 2020 report from the U.S. geological society. That amount would fill nearly 41 million bathtubs.

Algae bloom kills hundreds of sea lions off California

Hundreds of sea lions off the coast of California have been poisoned this year amid a “highly unusual” algae bloom that has persisted in southern and central parts of the state into October.

Experts believe the blooms, which are becoming more common, may be linked to warming and changing ocean conditions. They harm sea life when algae produce a neurotoxic chemical that can be taken up by fish and crustaceans and absorbed by the larger animals that eat them.

Off the US west coast, the proliferations of algae, sometimes called “red tides”, usually peak in the late spring. For the last three years, however, harmful blooms have come on strong in the summer and, this year, lasted into autumn before mostly petering out.

That is “highly unusual,” according to Clarissa Anderson, a researcher with the Scripps Institution of Oceanography, who is also the director of the Southern California Coastal Ocean Observing System, which tracks harmful algal blooms.

“It’s catching us all off guard,” Anderson said.

Progress seen on overall industry emissions, even as oil and gas emissions rise, EPA finds

By Shannon Kelleher

US power plants, the largest stationary sources of greenhouse gases in the nation, continue to show reduced emissions but the good news from that sector comes as oil and gas emissions rise, according to new regulatory data.

Power plant emissions totaled about 1.5 billion metric tons of carbon dioxide last year, down 7% from 2022, the US Environmental Protection Agency (EPA) reported. The agency collects data from over 8,000 industrial facilities for its Greenhouse Gas Reporting Program, accounting for about half of total US emissions.

However, greenhouse gas emissions from petroleum and natural gas plants increased 1.4% in 2023 over 2022, and the 2023 tally was up 16.4% from 2016, the EPA said.

Nine coal-fired power plants were among the top ten greenhouse gas-emitting industrial facilities for 2023, along with a Texas-based ExxonMobil refinery.

The worst emitter – for the ninth year in a row – was the James H Miller power plant outside Birmingham, Alabama.

Altogether, large industrial facilities’ greenhouse gas emissions, the chemicals that are driving human-caused climate change, dropped by 4% last year, the EPA reported.

“The progress is largely driven by the power sector, [which] has seen steadily declining emissions,” Amanda Levin, director of policy analysis at the National Resources Defense Council, said in an email, noting that the change reflects a shift away from coal over time. “The power sector can, and must, continue to decarbonize,” she said.

Deadly refinery leak adds to US toxic accident toll

By Dana Drugmand

A Texas oil refinery with a history of environmental violations was the site of a deadly hydrogen sulfide leak last week, killing two people and injuring more than two dozen others and adding to a long list of US industrial accidents US regulators say they are trying to rein in.

The chemical release is also the latest accident at the Houston refinery. The facility has been cited for nearly 2,000 environmental violations over the past decade.

Located in Deer Park, Texas along the Houston Ship channel, the 1500-acre refinery complex is owned by the Mexican oil company PEMEX, which took over full ownership of the facility from Shell in 2021.

The incident at the refinery, which occurred on the afternoon of October 10, killed two PEMEX employees, and at least 35 others were treated on the scene or transported for further medical attention, according to officials.

Hydrogen sulfide is a colorless, extremely flammable, highly toxic gas that gives off a rotten egg odor. Exposure at lower concentrations can cause headaches, dizziness, nausea, irritation of the eyes, throat and respiratory tract and loss of smell, and acute exposure at high concentrations can result in unconsciousness and even death.

“Unfortunately, Texas has a poor track record of forcing petrochemical facilities to take safety and compliance seriously,” Luke Metzger, executive director of Environment Texas, said in a statement. “It makes me wonder if this awful incident could have been prevented.”
