Particulate Matter

Holcim is the first cement plant in the nation to voluntarily install an industrial catalytic converter called SCR on its smokestack, significantly cutting smog-forming air pollution in DFW.  But despite operating only 26 miles from EPA headquarters, the Agency and State of Texas still claim the technology isn't "feasible"     Downwinders is proud to announce Midlothian's Holcim […]

There are no shortages of studies linking bad air with birth defects and premature births. But until now no one has taken on the task of trying to add up the national toll in both lives and money. In a study published in Environmental Health Perspectives on Tuesday, UCLA researchers estimated that almost 16,000 premature births across the […]

As you might have already heard, last week the EPA announced it was rejecting Texas' proposed rapid-response,140-year plan for restoring air quality and visibility in National Parks affected by pollution from the state's largest industrial facilities, primarily coal-fired power plants, aka, "the haze rule." Instead, the EPA decided to implement its own, slightly more decisive […]

Long term exposure to small particulate pollution from combustion sources, specifically coal-fired power plants, is up to five time more likely to kill you through heart damage than other forms of natural or human-made "PM." That's the conclusion of new comprehensive study comparing risks from breathing-in the tiniest specs of soot from combustion sources for […]

By this point, most of you will have been inundated with opinions and factoids about what President Obama's new "Clean Power Plan" will and won't do about climate change. Bottom Line: while it sets a precedent and an emissions floor for the largest sources of CO2, it does so in a way which turns out […]

It was just two months ago we featured the results of a study out of Boston that linked exposure to Particulate Matter, or PM pollution to brain aging and increased risk of dementia. Before that, we highlighted studies linking PM to autism and Parkinson-like symptoms. Now comes one more long-term, peer-reviewed report that connects ambient […]

Supporters who saw us out and about for Earth Day events could come by the table and pick up a new flyer of ours that cites at least four recent studies linking dirty air to Autism and other developmental disorders in children. Now comes a study that suggests the other end of the age spectrum […]

When environmental health advocates speak about the dangers of dirty air, the effects are often categorized as long term and cumulative. But the more scientists delve into the subtleties of the human body and what outside influences can do it, the more they realize that even short term exposures can be harmful. That's been especially […]

Anecdotally you may have heard commentary from a friend about the large numbers of kids in their child's age group who seem to have something wrong with their brain – ADHD or Autism for example. Turns out, there's some solid statistical evidence those conditions are on the rise. According to the U.S. Centers for Disease […]

Study: Less Smog Means Healthier Kids

by jim on March 5, 2015

Up to this point almost all studies about air pollution have tracked increasing levels of air pollution with decreasing levels of health. Respiratory problems, strokes, heart disease, Autism, Parkinson's-like symptoms – they've all been linked to exposure to high levels of air pollution vs exposure to less severe air pollution. Now, comes a new study […]

Swiss-based Holcim Cement is requesting a permit amendment to add new piece of pollution control equipment to its Midlothian cement plant, one of three cement plants that make the city the "Cement Capitol of Texas" and the largest concentration of cement manufacturing in the U.S. Good news, right? The problem is that the company is […]

The latest chapter in a decades old mystery game of "Get a Clue" happens tomorrow morning, Monday, June 16th when representatives of the Sierra Club and Downwinders at Risk present their case against the current state anti-smog plan during the regional air planning meeting at the headquarters of the North Texas Council of Governments, 616 […]

For the second time in as many weeks, a new study shows dramatic air pollution problems surrounding one of America's major airports. Last week, it was the fact that Particulate Matter was four to five  times higher surrounding LAX, adding up to more annual pollution than more than half of the Los Angeles freeway system. […]

How do you monetize a human life? How about when that life is impaired with an illness? What's it worth to you not having to rush your child to the emergency room when they're turning blue during an asthma attack? What about to prevent a heart attack? These days we live in a cost-benefit world […]

Researchers at the Keck School of Medicine and the University of Southern California have just published a report in the American Chemical Society's Environmental Science & Technology journal that shows air traffic from Los Angeles International Airport is responsible for more air pollution than half of all the city's notoriously congested freeways with a plume extending […]

Over the last decade we've seen plenty of studies linking air pollution, and specifically Particulate Matter, or soot pollution, to heart disease and attacks. Now Dr. François Reeves,a Canandian cardiologist has a new book "Planet Heart: How an Unhealthy Environment Leads to Heart Disease," that puts those studies in context. “You can sum it up […]
