In addition to all this wildfire smoke, there is also an invisible pollutant called ozone that is making the air quality even worse on the Front Range. You may not be able to see the ozone pollution in the air, but you can see it on plants.
A 1987 treaty to repair a thin layer of ozone in the atmosphere that shields life on Earth from cancer-causing ultraviolet rays probably had the unintended benefit of preventing runaway climate change, even if that danger persists for other reasons, researchers said Wednesday.
Along Colorado's Front Range, bad air is becoming the summer norm. And while this year's pollution, which data shows is some of the worst in decades, may bother you now, it is relatively benign compared with what scientists project for the future.
Personal care products can generate half or more of the volatile organic compounds -- a primary ingredient in forming ground-level ozone -- in an urban area.
The state of Colorado wants all large businesses in the metro Denver area to track what their employees do before and after work when it comes to commuting.
Nitrous oxide is a potent greenhouse gas, 300 times more powerful than carbon dioxide. Global emissions of N2O are on the rise as a result of human activities — and their impact on ocean ecosystems.
With the shutdown in spring 2020 came a sharp reduction in traffic and a decrease in nitrogen oxide emissions worldwide — a unique research opportunity.
The manufacturing plant responsible for PFAS-coated fast food packaging pumps out loads of a banned ozone-depleting compound along with "forever chemicals."
"We already know enough about the harm being caused by these very persistent substances to take action to stop all non-essential uses and to limit exposure from legacy contamination."
The chemicals, linked to health problems including cancer and thyroid disease, have contaminated drinking water in Pittsburgh communities like Coraopolis and McKeesport.
