Toxic plastic pollution is everywhere, even clogged arteries. We asked a Colorado doctor how to stay healthy.


Micro- and nano-scopic sized pieces of plastic people use everyday can eventually find its way into the most unlikely of places, even in the plaque of clogged arteries of cardiac patients, a recent study found.

In the study, researchers in Italy reported finding “visible, jagged-edged foreign particles among plaque macrophages and scattered in the external debris.”

The researchers said the chemicals in those foreign particles were polyvinyl chloride, or PVC, and polyethylene, two of the most common materials used in everyday, household plastic items, like water bottles and PVC pipe. 

A separate recent study found there are 100 to 1,000 times as many pieces of plastic in a bottle of water as previously thought, and in another study from Yale, Americans who consume water from plastic bottles consume an estimated 90,000 more microplastic particles annually than people who only drink tap water. 

This week, Colorado has been covered in a gray haze of wildfire smoke and air pollution. Other studies have found microplastic particles can not only be ingested via the beverages we drink or the food we eat, but it can also be inhaled through the contaminated air we breathe. 

The Yale study estimates Americans ingest and inhale on average up to 121,000 microplastic particles a year.

Last year, students and environmentalists in the Denver metro area found microplastics in 16 major Colorado waterways — every single waterway they tested across the state.

Inside those chemicals, a controversial compound of durable chemicals can often be found: PFAS, or per- and poly-fluoroalkyl substances, commonly called “forever chemicals” because of their durability.

What makes plastics so great for household products is that they don’t readily break down. But that’s a problem once those chemicals are in our bodies — they just break up into smaller and smaller pieces, and continue to accumulate. 

“PFAS particles are unique, because our body doesn’t degrade them very well… ordinarily we have chemicals that break almost everything down that we’re exposed to, but these molecules are resistant to those normal processes, so we tend to accumulate them,” explained Dr. Anthony Gerber, a pulmonologist at National Jewish Health. “I think the big question is, in addition to accumulating them, are there structures within those forces that are also changing what cells do? So are they having a direct effect on cellular function, in addition to just sort of accumulating and sticking around?”

While Gerber did not work on the Italy study finding microplastics in artery plaques, he has been examining the ways in which pollutants interact in the body. 

“There’s this widespread sort of literature on what we call endocrine disruptors… different chemicals that have enough of a chemical match for our normal hormones that they can kind of operate and wind up taking over some of the same body’s signaling and machinery that responds to hormones,” Gerber explained. “We know that PFAS aren’t really strong endocrine disruptors, but they’ve also been shown to have weak activity, for example, in progesterone or estrogens, and so one of the questions is ‘does that weak activity translate into something that might cause disease?’”

But he added, “the other issue is, because they stick around for a long time, that accrual over time of having cells, which might have this higher exposure to hormonal signaling, could have an effect… and then the fact that they’re so persistent, could give you a mechanism where even a little bit of activity could wind up changing cellular behavior and promoting disease or other issues.”

In the study from Italy, researchers reported that people with microplastics in the plaque of their arteries were more likely to suffer more serious outcomes, including heart attack, stroke, or death. 

In a different study, scientists found higher amounts of microscopic plastic particles in the feces of people with inflammatory bowel disease.

While some recent studies are finding some associations between PFAS and microplastic exposure with serious medical conditions, Dr. Gerber says many more studies are needed. 

Meanwhile, the EPA has deemed some PFAS compounds that have been more readily studied as toxic to humans. 

For the first time ever, the EPA passed laws this year limiting certain PFAS in drinking water, and Colorado passed laws that will eventually ban the sales of certain products with PFAS, like dental floss and feminine hygiene products.

But still these chemicals are basically unavoidable in the world around us. They’re in everything from flooring to clothing to food wrappers and water bottles.

With the latest study out of Italy, we’re learning they may be building up in our bodies in an even more intrusive way than ever imagined. 

Gerber says the microplastics study in Italy was a novel approach, and will likely inspire more like it in Colorado. 

“It definitely opens up a potential way to start to do those comparison studies, which are so important for establishing a link between the chemicals, the plastics, and the PFAS being in the plaque, to actually being causal or changing the way the disease is presenting,” Gerber explained. 

So what can we do to protect our health, despite these tiny particles lurking all around us?

Experts say limiting your exposure to plastics and PFAS are a good step. For example, use glassware instead of plastic containers, call your water utility to ask about PFAS testing results, and filter your water if necessary. 

But most importantly, Dr. Gerber reminds us not to forget the basics of living a healthy life, like eating a healthy diet, avoiding processed foods, and exercising regularly, which he says helps protect the body and strengthens cellular function.

“If microplastics might be promoting coronary disease, you might not be able to avoid ingesting the microplastics, because they’re everywhere, but you can sure do the other things. You can keep your blood pressure low. You can exercise. You can get your cholesterol measured,” Gerber said. “So my advice would be to do all the things that we already know are beneficial to mitigate whatever unknown risk there might be from some of these chemicals.”

The American Chemistry Council, which represents more than 190 companies engaged in the business of chemistry, many of which manufacture and utilize PFAS and other plastic chemicals, provided the following written statement in full to CBS News Colorado for this report:

“The authors of the most recent study on microplastics and cardiovascular health, Marfella et al. (2024), point out that the results do not prove a link between microplastics and cardiovascular disease. They also cite several factors that – had they been accounted for – could have affected the study results. These include a patient’s socioeconomic status, lifestyle patterns such as food intake or alcohol use, and sample contamination.

“The study of microplastics is relatively new and evolving. The global plastics industry is helping to advance scientific understanding of microplastics and reduce plastic pollution that can become a source of them in the environment – both key recommendations in the World Health Organization’s (WHO) 2022 report. Our industry has committed $15 million to fund independent research, with more than $7.4 million disbursed since 2021 to academic institutions around the globe.

“Additionally, through the International Council of Chemical Associations’ (ICCA) Microplastics Advanced Research and Innovation Initiative (MARII), we’ve created a global platform to help scientists, academia, and research institutions share information and collaborate on microplastics research. ACC supported the Save Our Seas 2.0 Act, bipartisan legislation which provided funding for more research on microplastics.

“Regarding chemistry production and use, ACC’s members are committed to producing chemistries that offer important safety, product performance and durability benefits and that can be used safely. Our members undertake extensive scientific analyses to evaluate potential risk of their chemicals, from development through use and safe disposal. We work with regulators, retailers and manufacturers to provide them with information about our chemicals.

“Meanwhile, we continue to work with EPA, FDA and other federal agencies to strengthen our regulatory system and help ensure that policies are made using the best-available science and the weight of the evidence to make decisions. In fact, chemicals in commerce are subject to government oversight, primarily by six federal agencies (CPSC, DHS, DOT, EPA, FDA, and OSHA), under more than a dozen federal laws and regulations. Today, chemistry products introduced or imported into the U.S. undergo rigorous review and approval processes by federal agencies, such as EPA and FDA.”

How the Colorado Rockies Are Actually Building Its Opening Day Roster


The Colorado Rockies are seeking the right balance and experimenting under their first full-year manager, Warren Schaeffer.

It’s a different Rockies roster compared to last season. There are new faces on the active roster for the start of the 2026 season. Having a team with youth and a mix of veterans can be a successful formula for the Rockies.

Knowing how the elevation affects things in Colorado, the Rockies will see which pitcher can thrive playing in Coors Field. Anything can happen this season.

The Rockies Must Have A Roster That Can Stay Durable

A Rotation of Veterans

Rockies president of baseball operations Paul DePodesta added several arms over 34, including Michael Lorenzen, Jose Quintana, and Tomoyuki Sugano.

The fifth starter will be a competitive battle. The Rockies have options in who will win that fifth and final spot. Here is the prediction of the Rockies’ starting rotation:

  • Kyle Freeland
  • Michael Lorenzen
  • Ryan Feltner
  • Jose Quintana
  • Chase Dollander

Ryan Feltner has battled injuries. The 29-year-old suffered back spasms and shoulder injuries, preventing him from performing in 2025. He’s determined to have a breakout season. 

He had a lot of momentum in his final 15 starts of the 2024 season. Feltner posted a 2.75 ERA and finished with a career-high 162 1/3 innings. Feltner has been building his weight-room capacity and getting himself ready for the new season. Hopefully, he can stay healthy and produce.

Flexibility on the Infield

The Rockies’ acquisition of Willi Castro was a smart move. We know the Rockies’ future at shortstop is Ezequel Tovar. However, the Rockies organization is being cautious. They want to make sure they have an extra body on hand in case something goes south. Castro is a former All-Star and a versatile defender. 

Eduoard Julien is known for playing second base, but he can also play first base if the Rockies need him there. It all depends on many situations and circumstances. Julien is one of the players on the Rockies roster who must prove his worth.

In terms of first base, TJ Rumfield is a front-office option to serve that position. He has the size, length, and youth to play the position. Rumfield is having an impressive start to the spring so far. 

Current Roster and Opening Day Prediction Lineup

Tyler Freeman, 2B 
Mickey Moniak, DH 
Hunter Goodman, C 
Kyle Karros, 3B
Jordan Beck, RF 
Brenton Doyle, CF
Jake McCarthy, LF
TJ Rumfield, 1B

The lineup can change overnight, and especially in the next few weeks. If, for some reason, Freeman can’t okay second base to start the season, then Castro is the leading man to take the spot.

Colorado quarterback Dominiq Ponder dies in single-car crash at age 23, police say


BOULDER, Colo. (AP) – Colorado quarterback Dominiq Ponder died early Sunday morning in a single-car crash, police said. He was 23.

Ponder was driving a 2023 Tesla when he lost control on a curve and hit a guardrail, according to the Colorado State Patrol. The car struck an electrical line pole and rolled down an embankment.

Ponder was pronounced dead at the scene in Boulder County. Police said a preliminary investigation “shows that speed is suspected as a factor.”

The Buffs were slated to begin spring practice on Monday.

“God please comfort the Ponder family, friends & Loved ones,” Colorado coach Deion Sanders posted on X. “Dom was one of my favorites! He was Loved, Respected & a Born Leader. Let’s pray for all that knew him & had the opportunity to be in his presence. Lord you’re receiving a good 1.”

Colorado offensive coordinator Brennan Marion reposted Sanders’ statement and called Ponder a joy to be around and coach.

“Getting that call from his dad today didn’t feel real,” Marion posted. “Love you Dom! God cover his family & our team, especially our qb room!”

Colorado athletic director Fernando Lovo said Ponder “epitomized the values of passion, enthusiasm, leadership, toughness, and intelligence that were revered by his teammates and coaches alike.” The athletic department said it would make counseling resources available to players and staff.

Fellow Colorado quarterback Colton Allen also paid tribute to Ponder on Instagram.

“Dom, you were a blessing to so many people,” Allen wrote. “You had a presence about you that just made everything better. You brought so much joy to me and everyone around you. I’m grateful for every lift, every practice, every rep, every conversation we got to share. I’ll carry those with me for the rest of my life.”

The Big 12 Conference extended its condolences in a post on X.

Colorado lawmakers duel over data centers: Grant millions in tax breaks or regulate them without incentives?

Colorado lawmakers duel over data centers: Grant millions in tax breaks or regulate them without incentives?


Colorado lawmakers are deciding this year between two disparate approaches on data centers — one that aims to lure them to the Centennial State with millions of dollars in tax incentives and another that would implement some of the strictest statewide regulations in the country on the booming tech industry.

Either of the two competing bills would create the state’s first regulations specific to data centers. Sponsors of both bills say they hope to minimize environmental impacts from the power and water demands of the centers, while also ensuring that the cost of new infrastructure they need doesn’t wind up on residents’ electric bills.

Both bills are sponsored by Democrats but differ widely in what they’d do.

The bill supported by the data center industry — House Bill 1030 — would incentivize companies to comply with regulations in exchange for large tax breaks. The legislation would not regulate data centers whose owners forgo a tax break.

The other bill — Senate Bill 102 —  would offer no incentives, instead imposing regulations on all large data center development across the state. It is supported by environmental and community groups.

“We want to make sure that as data centers come here, they come on our terms,” said Megan Kemp, the Colorado policy representative for Earthjustice’s Rocky Mountain office.

The bills have landed as debate over the future of data center regulation intensifies across the state. Data centers house the computer servers that function as the main infrastructure for the digital world. They crunch financial data, store patients’ health information, process online shopping, register sports betting and — increasingly — make possible the heavy data demands of artificial intelligence.

Several companies have begun construction on large data centers across the Front Range in recent years. A 160-megawatt hyperscale facility is under development in Aurora and could consume as much power as 176,000 homes once completed.

The construction of a 60-megawatt data center campus in north Denver has angered those who live by the site and prompted Denver city leaders last week to call for a moratorium on new data center development while they craft regulations for the industry. Larimer County and Logan County have enacted similar moratoriums.

Hundreds gathered Tuesday night at a community meeting about the northern Denver campus owned by CoreSite. Frustration in the crowd — which filled overflow rooms and the front lawn of the building that hosted the meeting — erupted as residents of the neighborhoods surrounding the center expressed concerns about how it would impact their air quality, power and water supplies.

Attendees said they did not know the data center was being built until they saw construction underway.

CoreSite leaders had planned to attend the meeting. But they pulled out of participating the day before because of safety concerns, company spokeswoman Megan Ruszkowski wrote in an email. She did not elaborate on the concerns. A Denver police spokesman said the department did not have any record of a police report filed by CoreSite in the days prior to the meeting.

CoreSite’s absence left officials from the city and utilities to answer the crowd’s questions and field their frustrations. City leaders told attendees that they had no say in whether the data center could be built because there are no city regulations specific to the industry.

“Data centers are proliferating quickly and we don’t know all the impacts,” said Danica Lee, the city’s director of public health investigations. “That’s why we need this moratorium.”

Promises of future regulation meant little to the residents of Elyria-Swansea, where the data center is scheduled to go online this summer. More than an hour into the meeting, a man took the microphone. He noted that so much of the conversation had focused on technicalities — but the information provided had not answered a question on many residents’ minds.

“How do we stop it now?” he asked, to a loud round of applause from the room.

Transformative opportunity?

Some in the state Capitol think more data centers would be beneficial for Colorado.

Supporters of the tax incentive bill in the legislature said luring the industry to Colorado would create high-paying jobs, help pay for electrical grid modernizations and strengthen local tax bases.

“This could be transformative for the state,” said Rep. Alex Valdez, a Denver Democrat who is one of HB-1030’s sponsors.

In exchange for complying with rules, data center companies would be exempted from sales and use taxes for 20 years for purchases related to the data center, like the expensive servers they must replace every few years. After two decades, the companies could apply for an extension to the exemption.

To earn the tax break, data center companies would have to meet requirements that include:

  • Breaking ground on the data center within two years.
  • Investing at least $250 million into the data center within five years.
  • Creating full-time jobs with above-average wages, though the legislation doesn’t specify how many jobs would be required.
  • Using a closed-loop water cooling system that minimizes water loss, or a cooling system that does not use water.
  • Working to make sure the data center “will not cause unreasonable cost impacts to other utility ratepayers.”
  • Consulting with the Colorado Department of Natural Resources about wildlife and water impacts.

While the bill would exempt data centers from sales tax on some purchases, they would still be on the hook for all other taxes, Valdez said, and would bring both temporary and permanent jobs. The bill does not specify how many permanent jobs must be created to qualify for the tax break.

Dozens of other states have enacted tax incentive programs for data centers. Such incentives are a key factor that companies weigh when deciding where to build, said Dan Diorio, the vice president of state policy for the Data Center Coalition, an industry group.

“Colorado is not competitive right now,” he said.

Figuring out the projected impact of the bill on the state’s finances gets complicated.

The legislature’s nonpartisan analysts estimated that the state would miss out on $92.5 million in sales tax revenue in the first three years, assuming a total of 17 data centers would qualify for the tax breaks in that time period.

But Valdez said that is revenue that the state otherwise wouldn’t see if the data centers weren’t built here. And the companies would still pay all other state and local taxes, he said.

“We see it as unrealized revenue, rather than a tax cut,” he said.

Some of that lost tax revenue would be offset by an increase in income taxes paid by low-income families, according to the bill’s fiscal note.

That’s because the projected decrease in sales tax revenue in the first year of the program would decrease the amount of money available for the state to provide its recently enacted Family Affordability Tax Credit. State law ties the amount available for the family tax credit to state revenue growth and whether the state collects money above a revenue cap set by the Taxpayer’s Bill of Rights. TABOR requires money above that level to be returned to taxpayers.

If the state doesn’t have excess revenue, it can’t fund that tax credit.

In the next fiscal year, which begins in July, data center companies would avoid paying $29 million in sales taxes, which would trigger a change in the family tax credit. Low-income families would be made to pay a total of $106 million more, the fiscal note estimates.

Bill sponsors are planning to address the fallout for the tax credit in forthcoming amendments, Valdez said.

“We’re not out to trigger any negative impacts to low-income families,” he said.

Baseline guardrails

Forgoing tax dollars during a state budget crisis is a hard sell to Rep. Kyle Brown, a Louisville Democrat sponsoring the regulatory bill. He and other supporters of SB-102 aren’t convinced tax incentives are necessary to bring data centers to the state.

Major construction projects are already underway, he said. In Denver, CoreSite chose not to pursue $9 million in tax breaks from the city but continued construction on its facility regardless.

“The point of our policy is (putting) reasonable, baseline guardrails on this development so it can be smart,” Brown said.

Brown last session co-sponsored a failed bill with Valdez that offered tax incentives to data centers. Since then, however, he’s seen other states that offer tax incentives express buyers’ remorse, he said.

Brown pointed to concerns in Virginia about rising electricity costs due to data center demand and a proposal by the governor of Illinois to suspend the state’s tax credit so that the impacts of the data center boom it sparked could be studied.

His bill this session — co-sponsored by Sen. Cathy Kipp, a Fort Collins Democrat — requires that data centers over 30 megawatts:

  • Draw as much power as possible from newly sourced renewable energy by 2031.
  • Pay for any additions or changes to the grid needed to serve the data center.
  • Adhere to local rules about water efficiency.
  • Limit the use of backup generators that consume fossil fuels; if such generators are necessary, they must be a certain type that limits emissions.
  • Conduct an analysis of the data center’s impacts on local neighborhoods, engage in community outreach and sign a legally binding good-neighbor agreement if the community is disproportionately affected by pollution.

Owners of data centers would also need to report metrics annually to the Colorado Department of Public Health and Environment. They would cover the center’s annual electricity consumption, how much of that power came from renewable sources, the total number of hours backup generators were used and annual water use.

Utilities, too, would face additional requirements.
