UI Center for Global and Regional Environmental Research co-director Dr. Gregory Carmichael delivered the 34th Annual Presidential Lecture to a crowded assembly hall at the Levitt Center for University Advancement on Sunday.

The lecture, titled “What Goes Around, Comes Around: The Global Reach of Air Pollution” featured opening remarks from University of Iowa President Bruce Harreld. Quoting Dr. Jerry Schnoor, Carmichael’s co-director at CGRER, President Harreld joked, “Greg is now more traveled than George Clooney’s character in Up in the Air, four million miles and counting.” Carmichael’s extensive research of the long-range transport of air pollution has taken him to many parts of Eastern Asia, South America, Africa and Europe, among other locations.

Carmichael’s lecture was organized into three parts: the global reach of air pollution, the link between climate change and air pollution, and a finally, a discussion about the action necessary to curb air pollution worldwide. The lecturer made a strong case for air pollution research, citing that it is the root cause of 7 million avoidable deaths per year. Carmichael pointed out that air pollution has economic consequences too; each year, it leads to loss of 10 percent of U.S. soybean yields.

The lecture encouraged a sense of urgency when it comes to cleaning up the atmosphere. Carmichael warned, “That molecule that we put in the air today will stay in the air for a long time.” He went on to say that 20 percent of carbon dioxide released into the atmosphere today will remain there for thousands of years. Professor Carmichael’s research focuses primarily on the utilization of comprehensive computer models and big data to simulate the interplay of air pollutants with weather and climate.

His work has been instrumental in understanding the way in which air pollutants from China move across the Pacific Ocean and affect the Western U.S. He said, “Fifteen to twenty percent of clean air policies in the Western U.S. are being offset by Chinese emissions.”

Above all, the Karl Kammermeyer professor of chemical and biochemical engineering emphasized his passion for instructing and advising students. Carmichael has supervised the research of 40 PhD and 35 Masters of Science students at the University of Iowa.

Co-director of the University of Iowa Center for Global and Regional Environmental Research (CGRER), Gregory Carmichael, will give this year’s University of Iowa Presidential Lecture.

Carmichael became faculty at the University of Iowa in 1978 after earning a BS in chemical engineering at Iowa State University and a PhD from the University of Kentucky. Nearly four decades later, the Karl Kammermeyer Professor of Chemical and Biochemical Engineering remains devoted to studying the global impact of pollution on air quality.

In an interview with IowaNow, Carmichael recounts how he initially became interested in air quality issues. He said, “At the time I was doing my graduate studies, acid rain was emerging as a big problem. That was really the first air pollution problem that demonstrated to people that we could have an impact beyond our local environment.”

Carmichael has won several awards including the Regents Faculty Recognition Award in 1998, the American Institute of Chemical Engineers Lawrence K. Cecil Award in 2012, NASA Group Achievement Awards in 2005 and 2009. Over time, Carmichael’s research became increasingly international. In the most recent fifteen years, his research team has has conducted air quality forecasting field experiments in Chile, California, the Arctic, and Beijing.

Much of his research considers how air pollution travels intercontinentally. He said, “We have done a lot of work on this topic over time, and this long-range transport of pollution is now being taken into consideration in the management of U.S. air quality and in international discussions. Wherever the emissions are occurring, they have an impact not only locally but globally as well.”

Carmichael became co-director of CGRER in 1991, and currently serves alongside Dr. Jerry Schnoor, University of Iowa professor of Civil and Environmental Engineering.

Anti-smog police: one part of Beijing’s fight for air quality

A new environmental police force is taking to the streets of Beijing to combat the city’s dangerous smog problem.

Beijing’s mayor, Cai Qi, announced this weekend that the officers will patrol the city looking for “open-air barbecues, garbage incineration, biomass burning, [and] dust from roads” that add to the city’s smog problem. Cai Qi’s announcement comes after Beijing experienced particularly dangerous air quality during the first week of 2017, and 72 Chinese cities were placed under pollution alerts.

Mayor Cai Qi said, “I totally understand the public’s concerns and complaints over air pollution,” and admitted to routinely checking the air quality index “first thing in the morning.”

The mayor announced that the city is taking additional measures to improve air quality. Beijing will close its only coal-fired plant, and in 2017 “coal consumption will be cut by 30 percent to less than 7 million tonnes” and “another 300,000 high-polluting old vehicles will be phased out,” according to China’s state-run Xinhua news agency.

Despite last week’s “red alert,” which temporarily shut down some pollution-producing operations, China’s environment ministry found that some 500 construction sites and businesses as well as 10,000 vehicles remained active in violation of the ban.

Chinese officials acknowledge that industry and automobiles are the primary causes of the hazardous smog problem, but reports state that the government is hesitant to crack down on major polluters in fear of economic consequences.

A study published in the November edition of the journal Science of the Total Environment, found that smog is related to one-third of all deaths in China, amounting to at least one million deaths per year.

Experts urge Iowans to test for radon gas in homes

As temperatures in Iowa plummet, residents are spending more time indoors, and some experts say there could be associated health risks.

Health officials and experts publicly encouraged Iowa residents to have their homes tested for radon this week. Anthony Salcedo, service manager at Thrasher Basement Systems in Omaha and Council Bluffs, said the odorless, colorless gas is found in many homes in the area.

Salcedo said, “We’re plagued with it, Iowa, Nebraska, we actually lead the country. It’s in about 70% of all homes.”

He noted that the presence of radon has nothing to do with the construction of the home. Salcedo explained,

“It’s not a foundation issue, it’s basically just what we’re building on. It could be a brand new home, it could be a 50-year-old home. We have a lot of clay soil and there’s no way to stop it on the front end. The soil breaks down, the uranium deposits, the radon gases will eventually make their way into your home and cause those health issues.”

Radon inhalation is the leading cause of lung cancer among nonsmokers, it leads to 400 deaths from lung cancer in Iowa each year. Paul Niles, a certified physician’s assistant at Akron Mercy Medical Clinic, has set out to educate his patients about radon.

Niles said, “Most people confuse radon with carbon monoxide.”

At-home radon testing kits can be purchased for about ten dollars from most hardware stores. According to the U.S. Environmental Protection Agency, if the test reads above 2 picoCuries per liter of air (pCi/L), homeowners should consider having a radon mitigation system installed. Niles explained that the Akron Mercy Medical Clinic has had a mitigation system installed. A pipe along with a fan pushes radon gas from underground into the open air outdoors.

He said, “Every county has high levels of radon. While you’re outside in the environment, it doesn’t really cause any health problems, but it’s when you’re in confined spaces that it can really do damage to the lungs.”

Buchanan County ISU Extension and Outreach has partnered with Buchanan County Environmental Health to provide a free public radon workshop. Residents can attend the workshop to learn more about radon, how to test for it at home and what to do after the test results come in.

Air pollution kills 600,000 children annually

Some two billion children worldwide are breathing air that contains pollutants which exceed the minimum air quality standards set by the World Health Organization (WHO), according to a recent report from UNICEF.

The first of its kind, the study used satellite imagery in order to determine areas that contain the highest concentrations of air pollutants. It revealed that roughly 300 million children live in places “where outdoor air pollution exceeds international guidelines by at least six times.” While 92 percent of the world’s total population breathes air containing dangerous levels of pollutants, experts say that children are especially vulnerable. The report stated that children breathe about twice as quickly as adults, which means they can inhale more air relative to their body weight. Their lungs are also still developing and may be more prone to infection. Air pollution accounts for 1 in 10 deaths of children under the age of five, and takes the lives of about 600,000 children of the same age range annually.

UNICEF Executive Director Anthony Lake said in a statement, “Pollutants don’t only harm children’s developing lungs — they can actually cross the blood-brain barrier and permanently damage their developing brains — and, thus, their futures. No society can afford to ignore air pollution.” The report elaborated upon the social and economic implications of breathing highly polluted air. It read,

“The combination of respiratory, cardiovascular, cognitive, morbidity and reproductive health effects of air pollution have biological as well as social and economic effects that last a lifetime. These include health conditions, school attendance, school performance, health costs and productivity, which affect income, poverty and inequalities. Air pollution, through its massive and cumulative impact on the overall health and well-being of children and parents, can perpetuate intergenerational cycles of inequality.”

Experts say the issue is exacerbated by industrialization, with the majority of outdoor air pollution attributable to vehicle emissions, heavy use of fossil fuels, burning of waste, and dust. In a statement, UNICEF asked countries attending the 2016 United Nations Climate Change Conference to tackle issues related to air quality for children directly. The report said, “Unless action is taken to control outdoor air pollution, studies show that outdoor air pollution will become the leading cause of environment-related child death by 2050.”

This week’s On The Radio segment discusses the Lake Michigan Ozone Study.

Transcript: Researchers at the University of Iowa are taking part in a collaborative field campaign to better understand the sources and transport of ozone near Lake Michigan.

This is the Environmental Focus.

The Lake Michigan Ozone Study is a joint effort of scientists at the University of Iowa, University of Wisconsin-Madison, and other research institutions to gain useful information about the concentration of ozone along all sides of the Lake Michigan shoreline.

Commissioned by the Wisconsin Department of Natural Resources and the Lake Michigan Air Directors Consortium, the study’s objectives include an evaluation of current regional ozone models and the effect of Lake Michigan’s breeze circulation on ozone transport.

Communities with little industrial activity on all sides of Lake Michigan have consistently experienced ozone levels higher than the EPA’s limit of 70 parts per billion.

Project organizers are still seeking additional  funding in order to install high tech, real-time monitors at various ground measurement sites in the region.
