Lee Zeldin, Trump’s EPA nominee, pledges independence from industry ties in senate hearing

By Douglas Main

Incoming President Donald Trump’s nominee to lead the Environmental Protection Agency (EPA) appeared on track for confirmation after a Senate hearing Thursday in which he pledged independence from industry money and influence.

Senators with the Committee on Environment and Public Works quizzed nominee Lee Zeldin, a former Congressman from eastern Long Island, on a wide range of issues, including his associations with, and financial ties to, the fossil fuel industry, his stance on government inducements for electric vehicle expansion, and environmental justice issues.

In one line of questioning, Sen. Sheldon Whitehouse, a Democrat from Rhode Island, pressed Zeldin on how he would “separate” his work at EPA from the demands of the fossil fuel industry, in particular.

Zeldin has numerous ties to what Whitehouse described as a “climate denial front group,” and has been the recipient of what Whitehouse said was nearly $300,000 from the oil and gas industry back to 2007, and “large campaign support” from the wealthy Koch family, which runs a variety of businesses involved in oil and gas exploration, pipelines, refining, and chemical production, among others.

Zeldin said the connections would have no role in how he leads the EPA.

“There is no dollar, large or small, that can influence the decisions that I make, who has access to me and how I am ruling in my obligations under the law,” he responded.

“Well good luck standing up to these guys cause they’re going to come at you,” Whitehouse said.

Fluorinated drugs, a type of PFAS, widely contaminating US drinking water

By Douglas Main

New research suggests that fluorinated pharmaceuticals — a category that includes well-known medications such as Prozac and Flonase — are showing up in the water supply of millions of people. These drugs and their breakdown products are technically classified as being per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals,” which as a chemical class is the subject of worldwide health concern.

A study published January 6 in Proceedings of the National Academy of Sciences found that the bulk of PFAS entering and exiting wastewater treatment plants is made up of these fluorinated drugs. Notably, the researchers determined that the pharmaceuticals were largely not removed from the water by conventional wastewater treatment practices.

This pharmaceutical material “doesn’t get treated in the wastewater treatment plant, and it doesn’t break down,” said Bridger Ruyle, study co-author and researcher at New York University. “And we know [these chemicals] can be re-entering drinking water supplies.”

The study estimates that this material contaminates the water supply of around 23 million Americans, Ruyle said.

These drugs enter wastewater after being excreted by people. About 50% of drinking water utilities are located downstream of a wastewater outflow plant and regularly use varying amounts of this water.

A slight majority of this material was made up of only four drugs and one of their metabolites: the arthritis medication Celecoxib (Celebrex); flecainide (Tambocor), prescribed for arrhythmia; maraviroc (Selzentry), and one of its metabolites, used to treat HIV; and sitaglipt (Januvia), a diabetes drug.

“We don’t know that much about what the exposures or health risks are” for those drinking small concentrations of this material, Ruyle said.

Landmark study affirms fluoride’s link to lowered IQ, adds to debate

By Douglas Main

Fluoride exposure is consistently linked with lowered IQ, according to a landmark analysis of more than 70 published studies on the subject.

The paper, published January 6 in the journal JAMA Pediatrics and authored by scientists with the National Institutes of Health, found a significant inverse relationship between measures of fluoride exposure and IQ in 64 of 74 studies.

The study, the largest meta-analysis of its kind, found that those exposed to high levels of fluoride have measurably lower IQs, equivalent to a difference of nearly 7 IQ points, compared to those in the low fluoride groups. This conclusion came from 59 studies that looked at levels higher than those used in water fluoridation.

The study found the link between fluoride and IQ loss persisted even at low levels of fluoride, as measured in human urine samples.

The meta-analysis is an offshoot of the National Toxicology Program’s investigation into fluoride’s likely impact on neurodevelopment and cognition, published in August 2024, and comes at a time of heightened scrutiny of, and debate over, the practice of fluoridation of public drinking water.

In a seven-year-long court case that wrapped up in September 2024, US District Judge Edward Chen of the Northern District of California, ordered the US Environmental Protection Agency (EPA) to take regulatory action to eliminate the “unreasonable risk” that water fluoridation presents. The fluoridation of water at 0.7 ppm “poses an unreasonable risk of reduced IQ in children,” Chen wrote in his decision.

Many researchers are sharply divided over the issue, however.

Tribunal says Mexico violated trade agreement in banning GM corn

By Douglas Main

An international tribunal set up to resolve disputes between the United States, Mexico, and Canada has ruled that Mexico violated the terms of the international trade agreement in banning the import of genetically modified (GM) corn for human consumption.

The decision, handed down by a commission set up under the auspices of the US-Mexico-Canada Agreement (USMCA), was criticized by over a dozen civil and environmental groups, who argue that Mexico is well within its rights to restrict the import of this material for health precautions and others reasons.

Mexico has argued that it needs to ban GM corn to protect its citizens and the environment. Earlier this year, it filed a 189-page document with the tribunal outlining what it sees as the risks posed by GM corn and glyphosate.

“Mexico has legitimate concerns about the safety and innocuousness of genetically modified corn… and its indissoluble relationship with its technological package that includes glyphosate,” the Mexican government’s report states. There is “clear scientific evidence of the harmful effects of direct consumption of GM corn grain in corn flour, dough, tortilla and related products,” Mexico stated. More evidence is needed, Mexico says, to determine “whether and to what extent, such risks are transmitted to food products further downstream.”

The Mexican government said in a statement it would comply with the ruling. “The Government of Mexico does not share the panel’s determination, as it considers that the measures in question are in line with the principles of protection of public health and the rights of indigenous peoples, established in national legislation and in the international treaties to which it is a party.”

Genetically modified corn is used by most US growers; companies have engineered the crop to be toxic to certain insects and to tolerate being sprayed with certain herbicides. Corn, and products made with corn, have often been found to be contaminated with glyphosate, one of the active ingredients in Roundup weed killer, for instance, because farmers can spray the pesticide directly over the growing crop to kill surrounding weeds.

The U.S. has not done or commissioned the research necessary to really determine if GM corn has long-term effects on human health, said Chuck Benbrook, a long-time consultant and expert who worked with Friends of the Earth in defending the Mexican position. “The US government never did [an] appropriate risk assessment of GM corn, period,” he said.

EPA must tighten pesticide rules to protect pollinators like bees and butterflies, petition argues

By Douglas Main

US regulators should require pesticide makers to more thoroughly tests their products for toxicity to insects before approval, according to a petition submitted to the Environmental Protection Agency (EPA) on Tuesday by an environmental advocacy group.

Most pesticides registered for use in the US have not been rigorously tested for their impacts on insects other than honeybees, a single non-native species. Scientists and conservationists have argued for years that this system fails to protect pollinators and underestimates the toll of pesticides on these animals, which is especially relevant given the decline of many insect species worldwide.

The EPA only requires that manufacturers perform, at a minimum, three narrow tests on adult bees to study a chemical’s toxicity on insects.

“They’re not an appropriate surrogate for the other 4,000 wild species we have in North America, nor are they a surrogate for other pollinators like moths and butterflies,” said Rosemary Malfi with the Xerces Society for Invertebrate Conservation.

The petition was filed on behalf of Xerces by the environmental law group Earthjustice.

Many of proposed changes come directly from EPA experts or academics invited to advise the agency.

“They’re not following their own recommendations,” Malfi said.

Feds propose protecting monarch butterflies under Endangered Species Act

By Douglas Main

The US Fish and Wildlife Service (FWS) on Tuesday proposed listing the monarch butterfly as a threatened species, a move that follows years of mounting concerns about declining counts of the iconic insect.

The decision to grant the butterflies protections under the Endangered Species Act comes after years of analysis and demands from environmental groups for stronger protections for monarchs.

“Today’s monarch listing decision is a landmark victory 10 years in the making. It is also a damning precedent, exposing the driving role of pesticides and industrial agriculture in the ongoing extinction crisis,” George Kimbrell, legal director at the Center for Food Safety, said in a press release. The center is one of the groups that sued the government over the issue several years ago.

The group noted in its statement that the “once-common orange-and-black butterflies have declined by 90% in recent decades, with the latest count showing the second smallest population on record.”

Under the government proposal, critical habitat would be designated for the insect, and a recovery plan crafted. The proposal opens a 90-day comment period that will close on March 12, 2025, after which the FWS is likely to issue a final opinion. It is unclear how the incoming Trump Administration, which is expected to emphasize deregulation, will act on the proposal and comments.

Court rules USDA’s GE crop rules break law, must be reworked

By Douglas Main

US regulators made “significant” errors in adopting a new rule four years ago around the release of genetically modified crops, and must now strengthen oversight, a federal court ruled this week.

The US District Court for the Northern District of California sided with the National Family Farm Coalition and other plaintiffs in finding that a rule issued in 2020 by the US Department of Agriculture (USDA) related to regulation of genetically engineered (GE) crops ran afoul of other federal laws.

Close to 100 new GE plants have been exempted from USDA oversight since the 2020 rule took effect. The court vacated the rule, effective Dec. 2, and sent it back to USDA for “reconsideration consistent with this order.”

“This is a critical victory on behalf of farmers, the planet, and scientific integrity,” George Kimbrell, legal director for the plaintiff Center for Food Safety, and counsel in the case, said in a statement. “USDA tried to hand over its job to [the] pesticide industry and the Court held that capitulation contrary to both law and science.”

Up until 2020, most GE crops were evaluated by the USDA’s Animal and Plant Health Inspection Service (APHIS) before they were allowed to be used commercially. But during the first Trump Administration, the agency took a deregulatory course, making it easier to bring new genetically altered plants to market.

Several environmental groups sued in 2021, arguing that these 2020 rules violated the Endangered Species Act, the National Environmental Policy Act, and the Plant Protection Act.

In this week’s decision, US District Judge James Donato ruled that the USDA violated the Plant Protection Act, as well as the Administrative Procedure Act, by failing to account for harm caused by the 2020 rules. In re-writing these regulations, Donato wrote: “APHIS’s errors are significant.”

Can the world agree to a sensible treaty to end plastic pollution?

By Douglas Main

As the US faces the upcoming inauguration of a president known for opposing opposition regulations, delegates from the US and more than 170 countries are meeting this week try to finalize a global treaty to address plastic pollution, in a process organized by the United Nations Environment Program that launched back in spring of 2022.

Some advocates and countries say this meeting in Busan, South Korea, amounts to a last chance to set common-sense limits to prevent an upcoming wave of plastic pollution. The situation is already grim: The world makes approximately 430 million metric tons of plastic every year, more than the weight of all humans combined. Nearly three-fourths of this material ends up in landfills or the environment. If current trends continue, global plastic use and waste will nearly triple by 2060, according to the Organisation for Economic Cooperation and Development.

On one side are the “high ambition” parties, led by Norway and Rwanda, and 66 other countries. They’re pushing for a legally binding treaty that caps production, addresses the design and makeup of products, limits toxic materials, and controls for the pollution and harm caused throughout the entire life cycle of plastic production and use.

Other countries, including those that produce a lot of oil and plastic — such as Saudi Arabia, Russia, and China — have been resisting limits on production and many of these other demands.

The U.S. position in unclear. The Biden Administration made waves this summer in saying they would support efforts to curb production. And last week, the US Environmental Protection Agency (EPA) released a new “National Strategy to Prevent Plastic Pollution”, saying it aligned with the nation’s “commitment to negotiating an ambitious international agreement with the aim of protecting public health and the environment by reducing plastic pollution around the world.”

The EPA highlighted the “significant human health concerns” associated with exposures to plastic pollution, including cancers, reproductive health problems, heart attack, stroke and other problems. The EPA noted microplastics have been found in human breast milk and research has found them elsewhere in the body, including in the brain.

Still, this month, White House staffers reportedly told representatives of advocacy groups in a closed-door meeting that they would no longer support mandatory caps on production, and would take a more “flexible” approach to a deal, according to Grist.

Bioplastics may be toxic to soil organisms, study calls for more testing

By Douglas Main

Bioplastics, often considered a safer alternative to synthetic plastics, may in some cases be toxic to soil organisms, a worrisome finding that indicates a need for more thorough testing, according to a new study.

The work adds to a growing body of research suggesting that bioplastics, which are derived from plant materials or other biological feedstocks, are not necessarily safer than plastics that come from petroleum.

The new study, published this month in Environmental Science and Technology, found that two types of bioplastic fibers were more toxic to earthworms than were bits of conventional polyester. While promoted as “environmentally friendly,” the alternative materials actually may be more harmful in some ways than the conventional plastic, the study determined.

“We need more comprehensive testing of these materials before they are used as alternatives to plastics,” said Bangor University researcher Winnie Courtene-Jones, who is lead author of the study.

Bio-based fibers like viscose and lyocell are used in clothing, especially in fast fashion, but also in wet wipes and a range of other products. The study said more than 320,000 metric tons were produced in the textile industry in 2022 and that is expected to continue to climb. When such clothes are washed, they can shed fibers into wastewater. Thousands of tons of sewage sludge are added to farmlands around the world, which can directly transmit such fibers into the soil.

The study authors said they exposed worms to fibers from polyester, as well as viscose and lyocell, which are made from cellulose and used in “natural” fabrics. They found that after three days, 30% of the first group died, while the death toll was 60% for viscose, and 80% for lyocell.

Can anything be done to Trump-proof the environment?

By Douglas Main

As advocacy groups brace for a new administration under President-elect Donald Trump —fearing a slew of deregulation and policy changes that would undermine a range of environmental health measures —some are pondering ways to try to “Trump-proof” the planet.

Trump racked up the worst environmental record of any president during his first term, according to several advocacy organizations, and many worry his second time around will be even worse.

They expect across-the-board cuts to federal budgets and staff, including the Environmental Protection Agency, Department of Interior, and other agencies that play key roles in protecting human and environmental health. And they forecast efforts to reverse environmentally friendly policies protested by powerful corporate players.

“I suspect Trump will be less restrained than last time… more aggressive and damaging,” said Brett Hartl, with the Center for Biological Diversity. “We’ll wait for the storm to hit and fight back,” he added.

These concerns come after the Biden administration has implemented of many hard-fought measures such as new standards to address widespread contamination of US drinking water with per- and polyfluoroalkyl substances (PFAS), and environmental justice initiatives to better protect marginalized communities from industrial pollution.

The current administration has, just this month alone, completed a series of steps lauded by conservationists and environmentalists that include finalizing rules to limit oil drilling in the Arctic National Wildlife Refuge, and finishing a proposal to restrict oil exploration and grazing in 65 million acres of sage grouse habitat.
