Researchers at Pitt took a look at births in southwest Pennsylvania and found a link between exposure to chromium and styrene and autism.


The study is here. We’re going to do our best to summarize it below.


Who did the study?

The study leader is Evelyn Talbot. She’s an epidemiologist in the public health school at Pitt. Epidemiologists try to establish cause and effect for disease, but often, they are also looking for correlations – things that have a relationship to each other, but aren’t necessarily cause and effect. A correlation is what they say they have found in this paper.

Who was in the study?

Talbot’s team took a look at the medical history and talked to the moms of 217 children born between 2005 and 2009 who have a diagnosis on the autism spectrum. These kids live in Allegheny, Armstrong, Beaver, Butler, Washington or Westmoreland Counties. The researchers also looked at a similar number of children who weren’t on the autism spectrum and interviewed their moms. They also compared their findings to thousands of births in the area, but there were no interviews.


Um, 217 kids doesn’t seem like a lot. Is it?

Is 217 enough to do a study? The authors said that based on predictions of the number of children born in these counties in those years, they wanted to enroll about half the number predicted to have ASD (autism spectrum disorder). That would be 250 children. Pretty close!


How do you know the kids were exposed to anything?

The team used computer models based on pollution data collected by U.S. Environmental Protection Agency to predict the actual exposure of each kid in the study based on addresses during the study period. They looked at 30 different air toxics that are found in southwestern PA that have been known to effect development, our nervous systems or our hormone systems.


And they found what?

Of the 30 different air toxics they looked at (things like benzene, arsenic and lead), they found a pretty strong correlation between developing autism and exposure to styrene, an oily chemical that ends up in plastics and chromium, a metal that is sometimes used in steel production.


Now what?

The study is just the beginning, but since we already know that exposure to pollution can impact children and adults, the authors think that following up with monitoring the levels of styrene and chromium in the air can give us more data to better understand individual outcomes. One surprising thing is that we have no autism registry in PA. Given the number of people studying the disorders, and the list of potential causes, the researchers are calling on the state, if not the nation, to start a registry.

For the past year, local artists have used photography and interviews to try and visual thesocial, political, economic and health impacts of air pollution in the greater Pittsburgh area. We live in a region with about a dozen air quality monitors, gathering data about what we breathe. And guess what, nearly all of them record numbers in the worst one-third of the nation.

Hey folks – big news today out of PennEnvironment – they’ve filed their intent to sue ArcelorMittal, the global steel company, for what they describe as hundreds of violations of the Clean Air Act out of their plant in Monessen, south of Pittsburgh.


PennEnvironment held a press conference today to discuss the pending suit, with people who live in the neighborhood talking about how hard it is to live by the plant. The full text of their press release is below.



ArcelorMittal’s Pittsburgh-area Plant Commits Hundreds of Clean Air Act Violations, Raining Soot and Foul Odors on Local Residents


[PITTSBURGH, PA] – At a news conference held in front of the federal courthouse in downtown Pittsburgh, representatives of the citizen-based non-profit group PennEnvironment announced they’re taking the required steps to trigger a lawsuit against the world’s largest steel company, ArcelorMittal, to address hundreds of ongoing violations of the federal Clean Air Act.


The suit would address a wide variety of alleged problems at ArcelorMittal USA, Inc.’s Monessen Coke Plant, located twenty-five miles south of Pittsburgh on the banks of the Monongahela River. Local residents say the plant is fouling the air over a wide swath of southwestern Pennsylvania.


The required pre-suit notice letter, sent on behalf of PennEnvironment and its members to ArcelorMittal, as well as to state and federal regulators, alleges that residents of numerous nearby towns surrounding the plant have been showered with soot, acidic gases, and noxious odors since the idled, decades-old facility re-started in April 2014. These include the municipalities of Monessen, Donora, Monongahela, and Carroll Township, located in both Westmoreland and Washington counties.

“I’ve met with residents who live in towns all around this plant, and their stories about air pollution from this facility are gut-wrenching,” said David Masur, Executive Director of PennEnvironment. “Ever since the Monessen Coke Plant re-opened last year, local residents have had their quality of life diminished, have endured ongoing odors and soot, and have had to fear for their health and the health of their families. This is appalling and unacceptable.”


“The smell that emanates from the Monessen plant is consistently foul and sometimes so suffocating that I feel like a prisoner in my own home. I only get relief from these odors and pollution when I leave the area,” said Viktoryia Maroz, a resident of Donora, PA.


Photos of the facility can be viewed at hC4l. If using photos to accompany a news story, please credit as, “Logan Tilley.”


The Clean Air Act’s “citizen suit” provision allows private individuals and organizations to sue violators in federal court after first providing 60 days’ notice of their intent to file suit and of the violations to be addressed in the suit.


The Monessen plant’s 56 coke battery ovens heat coal at high temperatures to produce nearly 1,000 tons per day of “coke,” a form of carbon that is added to molten iron to produce steel. Coke from the Monessen plant is shipped to ArcelorMittal’s various North American steel mills.


The production of coke creates massive amounts of toxic, chemical-laden gases and fine particulate pollutants that, if not properly contained and treated, can cause serious environmental and public health problems when released to the surrounding environment.


The notice letter alleges a wide range of violations at ArcelorMittal’s Monessen plant, including:


• Operating the plant for days and weeks at a time while a key air pollution control device was out of service;
• Approximately 200 violations of the facility’s pollution limits for hydrogen sulfide (a toxic gas with a foul odor), sulfur dioxide (a respiratory irritant and contributor to acid rain), and particulate matter (which can lodge in the lungs and exacerbate respiratory problems);
• Failure to install a mandatory monitoring device needed to track the amount of hydrogen sulfide coming from the facility’s smokestacks.


At times, violations have been so egregious that ArcelorMittal’s emission levels have been up to eight times higher than the legally allowable limits.


ArcelorMittal USA, Inc., is headquartered in Chicago. Its parent company is headquartered in Luxembourg and has annual revenues of over $80 billion.


PennEnvironment’s lawsuit will be filed by the non-profit attorneys at the National Environmental Law Center (NELC), in the U.S. District Court for the Western District of Pennsylvania, located in Pittsburgh. The lawsuit will seek a court order requiring the Monessen Coke Plant to comply with its Clean Air Act permit, and civil penalties against ArcelorMittal to punish it for past violations and to deter future violations.


A separate class-action lawsuit (unrelated to the suit announced today by PennEnvironment) has been filed against ArcelorMittal’s Monessen Coke Plant, seeking monetary damages for residents suffering from noxious odors and soot.


“It’s outrageous that the world’s largest steel company, which brings in $80 billion annually, can’t find a way to comply with our cornerstone environmental laws and ensure the health and safety of nearby residents,” stated Masur. “That’s anything but being a good corporate neighbor.”

Today, the State Department of Environmental Resources has issued a “code orange” alert.  The air quality index is expected to enter the range of 101 to 150 for Pittsburgh, the Liberty-Clairton area in southeastern Allegheny County, and Indiana County.  This level of pollution puts young children, the elderly and people with respiratory problems in danger.

Did you see John Graham’s Op-Ed in the Pittsburgh Post Gazette last week? If not, click here. John, who is a senior scientist with the Clean Air Task Force, studies air quality here in Western PA.



A screenshot of the American Lung Association’s State of the Air 2015 report. Pittsburgh ranks in the top 10 for high levels of very small particles in the air. These particles can cause health problems.

The American Lung Association recently released their rankings of air quality nationwide. We are still in the top 10 for worst daily and yearly PM2.5 readings, even though we have been improving.


After the PG and others took the American Lung Association to task for basing their rankings on one monitor in our area, John said, hang on. Yes, that one monitor, the Liberty-Clairton monitor, gives really bad readings, but it’s not the only one.


Pittsburgh’s air is bad. Most of our monitors give readings in the bottom one-third of air quality in the nation. Think about it. Six hundred monitors nation wide. Two hundred in the bottom one-third. Most of Western PA’s one dozen monitors fall on that list.


Yes, it’s getting better, but the problem isn’t over. Is better air really good enough?



The Environmental Protection Agency recently designated Allegheny County as out of compliance with federal air quality standards for fine particulate matter, a type of air pollution known to cause premature death. The EPA’s detailed analysis shows that multiple local sources contribute to the county’s harmful levels of air quality.


We can do better. We need to do better.


Almost every other county – or 95 percent of the United States – already complies with the federal standards, set in 2012. And our country’s standards lag far behind those recommended by the World Health Organization (WHO) and the standards of one of our closest neighbors, Canada.


(NOTE: Blue counties – including Allegheny County – are those NOT in attainment. Source: EPA 2014)


Fine particulate matter kills tens of thousands of Americans each year. But it’s worth noting that solutions to this public health problem are well-understood and achievable. Also, for every dollar spent to reduce air pollution sources, many more dollars are saved by avoiding heart attacks, asthma and lost workdays and schooldays.


Since up to 66 percent of Allegheny County’s air pollution comes from sources within the county and Pennsylvania, the Breathe Project’s mission is to promote a collective understanding and vision that it is vitally important for all us to do more to improve our region’s air quality.


We need to do better, and we can do better.


Here are five ways our business, civic and community leaders can work together to reduce air pollution, and in so doing commit our region to having healthy air that is safe for all of us to breathe.


(1) Every reasonable step should be taken to ensure the largest local industrial air pollution sources are subject to stringent emissions controls and are not in violation of their permits. “Pay to pollute” is not a viable way to regulate facilities with violations.


(2) A comprehensive plan to reduce diesel emissions should be developed and various strategies should be employed to decrease their contribution to the problem. These efforts should include idling law enforcement, adoption of clean construction policies and retrofit/replacement projects. We should emulate some of the institutions in Pittsburgh that already have taken the lead to accomplish these goals.


(3) Mass transit, bike lanes and carpooling should continue to be incentivized.


(4) Laws on wood burning should be strengthened and enforced. There is no reason why entire portions of neighborhoods should be smoked out by a handful of wood burners whose emissions infiltrate into others’ homes and make yards virtually uninhabitable.


(5) Inventories should be conducted in the neighborhoods, schools and parks where we and our children live, work and play to assess their air pollution burden and contributing factors. With this information, steps should be taken to reduce sources within their control and to demand that regulators work harder and faster to clean up those sources outside of residents’ control.


We can act now to clean up our air. Let’s do it!

Local air quality groups are circulating a petition urging the Allegheny County Health Department to include air quality in the strategic plan they are adopting at the Board of Health meeting on Jan. 7. Please help move this important issue forward by signing.

Breathe Cam Lets Citizens Document Pittsburgh’s
Visual Air Pollution and Its Sources


Carnegie Mellon Technology Now Part of The Heinz Endowments’ Breathe Project


PITTSBURGH—A system of four cameras, called Breathe Cam, now keeps a constant watch on air quality over Pittsburgh, providing citizens with a new interactive tool for monitoring and documenting visual pollution in the air they breathe and even tracing it back to its sources.


Funded by The Heinz Endowments as part of its Breathe Project, the camera system was developed and deployed by the CREATE Lab in Carnegie Mellon University’s Robotics Institute. Anyone can access Breathe Cam online, where images of the Downtown, East End and Mon Valley skylines are updated around the clock.


Using the interactive controls, people can zoom in on items of interest, whether it’s a hovering brown cloud or individual smokestacks or coke plants. They can scan back in time to observe changes in visibility or to try to find the sources of dirty air. They also can skip back to particular dates and times that have been catalogued since the cameras were installed.


The researchers also have developed a computer vision tool to help people identify and quantify events of interest, such as releases from a smokestack. Users can correlate the visual conditions with hourly reports of fine particulate matter, ozone and other pollutant levels recorded by Allegheny County Health Department air monitoring stations.


“People can use Breathe Cam to gather visual evidence of what’s happening to the air they breathe, whether it’s for the entire city or for a pollution source that is a concern in their neighborhood,” said Illah Nourbakhsh, professor of robotics. “With a better understanding of the dynamics of our environment, people can work more effectively to improve conditions. This isn’t technology for technology’s sake, but for the sake of community empowerment.”


Breathe Cam includes four cameras that produce panoramic images: one atop Mount Washington’s Trimont Towers; another at 625 Liberty Avenue, Downtown; one directed toward the East End from the University of Pittsburgh’s Benedum Hall that was installed in October; and a camera overlooking the Mon Valley from Walnut Towers in Squirrel Hill.


“The launch of the Breathe Cam creates for Pittsburgh one of the world’s most sophisticated imaging technologies for visualizing air pollution,” said Grant Oliphant, president of The Heinz Endowments, which launched the Breathe Project in the fall of 2011 to improve air quality in southwestern Pennsylvania. “This powerful tool will help build public awareness about the effects of dirty air on our health and environment, while empowering people to better understand and reduce these impacts in their own communities.”


The technology behind Breathe Cam is similar to the CREATE Lab’s GigaPan system, which uses software to stitch together multiple photographs to create a large panorama with incredible resolution. But researchers, led by Randy Sargent and Paul Dille, have upgraded the system so people can explore the panoramas only minutes after the individual images are recorded.


“This is the first time we’ve had cameras that can take pictures this rapidly and do so 24/7,” said Sargent, senior systems scientist. “And we no longer have to wait hours to combine the photos into panoramas. Thanks to work by Paul Dille, it takes just five or 10 minutes to process each panorama. It’s enabled us to turn this into a service, not just a technology.”


Though people viewing Breathe Cam via their computers can zoom in on objects of interest, the resolution isn’t high enough to allow users to identify people. The researchers have taken pains not to compromise the privacy of individuals or their homes.


One computer vision tool will enable users to gather information from the cameras without constantly watching the images. The tool can be set to trigger when something of interest to the user, such as the release of smoke from a coke battery or smokestack, occurs. In addition to monitoring air pollution, the same tool can be used to detect train movement across the city.


With electronic cameras now commonplace, many individuals across the country already are using cameras to routinely monitor pollution sources. With Breathe Cam, Nourbakhsh noted, Carnegie Mellon and Heinz have developed a computer architecture for turning these camera feeds into an evidentiary system. He said work is underway to make such a system available to anyone who wants to share their camera feed with it. In addition, the Allegheny County Health Department and local environmental groups are partnering with CREATE Lab to use Breathe Cam technology in their efforts to monitor and improve air quality in the region.

“Snowflakes aren’t the only particles that will be falling in Downtown Pittsburgh this Christmas. A digital piece of artwork of a cascading waterfall of bright blues, pale yellows and shimmery particles will light up the outside of the Benedum Center on Penn Avenue until the end of December.”
“People walking along the sidewalk in front of the piece on Saturday night glanced up at it and its projector casually, but were more than likely unsure about the message behind it. Or unaware that at any given moment it could burst into orange and red flames. Those colors come as a result of pollutants in the air.”
Pittsburgh Post-Gazette: Particle Falls Sheds Light On Pollution

The Heinz Endowments’ Breathe Project today launches artist Andrea Polli’s Particle Falls, a captivating digital-media installation that provides a real-time visualization of air quality.


At a time of year when Downtown Pittsburgh is aglow with holiday lights that raise our spirits, the dazzling lights of Particle Falls are designed to raise public awareness about one of the city’s persistent challenges — air pollution.


Particle Falls, a video projection measuring approximately 60 feet by 20 feet, will illuminate the Benedum Center façade in the 700 block of Penn Avenue at Tito Way after dusk each night through Dec. 31. The projection features cascading “falls” of blue light overlaid with spots of color that represent fine particulate matter in the air detected in real-time by a monitor across the street. Fine particulate matter, also known as soot, is a mixture of solid particles and liquid droplets that measure just 1/30th the width of a human hair. More bright spots over the falls indicate more particles in the air.


“Pittsburgh ranks among the worst 10 percent of U.S. cities for average annual particle pollution, and our region lags far behind most areas in attaining federal standards,” said Phil Johnson, interim director of the Endowments’ Environment Program and director of the Breathe Project, a broad-based coalition working to improve air quality in southwestern Pennsylvania. “We felt it was important to bring Particle Falls to a busy Downtown corridor to engage the community in conversation about this problem and how we can work together toward solutions.”


Sources of fine particle pollution in the Pittsburgh region include cars, trucks, buses, trains, barges, construction, industrial facilities, power plants and residential wood burning. It is linked to a long list of serious health problems from cradle to grave, including asthma, heart and lung disease, cancer, adverse birth outcomes and even premature death. Exposures in Downtown Pittsburgh can be especially acute, as the rows of tall buildings create an urban canyon that traps air pollution.


Particle Falls was conceived and designed by digital-media pioneer Andrea Polli, associate professor of art and ecology at the University of New Mexico. Pittsburgh is the fourth city to host the temporary public artwork, made possible by a $62,500 grant from The Heinz Endowments. The artwork made its debut in 2008 in San Jose, Calif. Pittsburgh is the first city to use the air quality data generated by the installation for research through a partnership with scientists at the Center for Atmospheric Particle Studies at Carnegie Mellon University. Production support is being provided by the Office of Public Art and Flyspace Productions.


“It’s important to become more aware of what’s happening with our air, and to talk about it,” Polli said. “As an artist, I felt the best way to promote this dialogue was to take air pollution, something negative, and present it as a thing of beauty. I wanted to create a place that was beautiful and enjoyable to visit, but also to present particulate pollution, which is very problematic.”


Particle Falls will be open until midnight, rain or shine, through New Year’s Eve. The Office of Public Art will be on-site Tuesday and Friday evenings from 6 to 7 p.m. to provide interpretation of the artwork. Please note Particle Falls will be closed on Nov. 27 and Dec. 24-25.


On Dec. 13 from 4 to 6 p.m., an artist lecture and panel discussion will be held at the Trust Arts Education Center, 805-807 Liberty Ave., Downtown. Polli will talk about the process and technology behind Particle Falls and then join a panel discussion about air quality and public health. This event is made possible with the assistance of the Pittsburgh Cultural Trust. To register for this free event, visit or call 412-391-2060, ext. 237.

    #ICYMI: Pitt scientists studying southwestern Pennsylvania kids, OUR KIDS, find a link between air toxics called chromium and styrene, and autism.

    Environmental Health | Full text | Air toxics and the risk of autism spectrum disorder: the results of a population based case–control study in southwestern Pennsylvania

    Autism spectrum disorders (ASD) constitute a major public health problem affecting one in 68 children. There is little understanding of the causes of ASD despite its serious social impact. Air pollution contains many toxicants known to have adverse effects on the fetus. We conducted a population based case–control study in southwestern Pennsylvania to estimate the association between ASD and 2005 US EPA modeled NATA (National Air Toxics Assessment) levels for 30 neurotoxicants.

    Today at 9:18am • No Comments

    Sixty days ago, PennEnvironment said they would sue the world's largest steel company for violations of the Clean Air Act if the company did not take measures to deal with sulfur dioxide and hydrogen sulfide raining down on Monessen and neighboring communities.

    Penn Environment and the National Environmental Law Center reached out to the company, ArcelorMittal, an $80 billion global steel giant, to figure out how to reign in their coke works in Monessen.

    Today, they filed suit. The Monessen coke plant has violated federal air quality standards 225 times in the first 450 or so days since re-opening in April 2014.

    That's breaking the law EVERY. OTHER. DAY.

    The lawyers have heard from the company. They are hopeful that further meetings will be fruitful. But in the meantime, the people who live around the plant are breathing in these noxious, dangerous chemicals every day.

    Don't they deserve better?
