10 things we learned about chemicals & environmentFlickr: Photo by Bert van Dijk (Flickr/Creative Commons)

What better way to commemorate Earth Day than by learning about how our everyday actions affect the environment? This week’s Frontiers focused on common chemical pollutants and their impacts. IonE resident fellow and College of Science and Engineering professor Bill Arnold kicked off the talk, followed by Matt Simcik, associate professor in the School of Public Health and Ron Hadsall, professor in the College of Pharmacy. With conversations ranging from flaming couches to perspiration and peeing, here are 10 things we learned:

1. The good, the bad and the complex. Lately chemicals have been receiving a lot of flack for being toxic, but we must remember that we rely on chemicals for much of our life. Chemicals are a necessary and helpful part of life, but the properties that make them good for our industries, such as their stability and persistence, are often the same things that make them bad for the environment. Understanding how they interact in the environment is complex and can be influenced by features such as quantity, level of exposure and the specific setting.

2. PCB spells trouble. Polychlorinated biphenyls are manmade chemicals used for their stability, nonflammability, and high boiling point. PCBs were originally intended for industrial applications so it was assumed that they couldn’t easily be released into the environment. Then we discovered that PCBs are harmful to the environment and to humans, with health impacts including cancer and effects on the immune system. As persistent chemicals, PCBs do not easily break down once released into the environment, and they are able to travel far distances and accumulate in living things. PCBs were banned in1979, but they are still frequently found in the environment and in products produced before the ban.

3. The lesser of two evils? Sometimes referred to the “new PCBs,” polybrominated diphenyl ethers are used as flame retardants in many consumer products, including cars and furniture. Concerns over these chemicals include adverse neurobehavioral impacts on humans and ecotoxicity in many animals. Production of PBDEs started in the 1970s, peaked in the late 1990s, and began to be phased out beginning in 2009.

4. Think twice before washing your hands. If you’ve never been one to read product labels, now might be the time to start. The chemical triclosan can be found in many personal care products, including antibacterial hand soap and toothpaste, as an antibacterial agent. Production of triclosan started in the 1960s and increased rapidly, despite some studies saying that it does not provide any added antibacterial benefits. Furthermore, a University of Minnesota study showed triclosan is able to build up in the sediment of lakes, and it also forms dioxins when exposed to sunlight. The good news? Minnesota recently became the first state in the country to ban the chemical, effective January 1, 2017.

5. One of these things is not like the other. Research over the past few decades has made strides in understanding how chemicals act in the environment. Unlike PCBs and PBDEs, which travel easily, perfluorochemicals have a negative charge that binds them to things and keeps them relatively stationary. Yet, despite believing that PFCs shouldn’t go anywhere, researchers kept finding them all over the globe. Eventually, they discovered that the precursor chemicals were being distributed globally in the environment, which then transformed to form the PFCs.

6. Some 10–15 percent of all medications go unused. Pharmaceutical drugs are among the biggest sources of chemicals in the environment. While pharmacologists are trained to think about how medications affect human health, downstream consequences are sometimes unseen. When extra medication is thrown away or flushed down the toilet it enters the environment, through wastewater treatment plant effluents. These chemicals can then affect the organisms around them, as is evident from the recent reports of estrogen creating feminized fish. Researchers and policy makers have been looking into how to dispose of medication in a more responsible way. Regulations and take-back programs have started to make a difference.

7. Pass-through problems. The fact that 85–90 percent of pharmaceuticals are used does not mean these chemicals are staying out of the environment. Hadsall and colleague Lowell Anderson are exploring what happens to medications as they make their way out of our bodies and into wastewater. Conservatively, they estimate that 50 percent of what is consumed ends up in the sewage system and potentially the environment. This is significant, especially since millions of people around the world rely on various pharmaceutical drugs. Medical chemicals provide an added challenge because many people rely on pharmaceutical drugs, meaning reducing consumption or banning them may not be an option.

8. What now? Knowing what we now know about chemicals, Arnold, Simcik and Hadsall made recommendations about how we should move forward. We’ve already taken some steps by banning or phasing out known contaminants, but there are still concerns over how to best manage what’s already in the environment. Specifically, we need to invest more in thorough testing before using new chemicals. In addition, they recommend that the laws and regulations that govern these chemicals should be reevaluated and updated.

9. Education is important. In both medical and industrial products, the power of the consumer should not be undervalued. People tend to make different decisions if they know the consequences of their actions, so informing them about what’s included in products may affect their decision to buy or use these products. Consumers can also push back against suppliers and manufacturers, forcing them make changes accordingly. Because many of the laws and regulations governing chemicals have not been updated since they were written in the 1970s and 1980s, public education should also include information about regulations and whether they are outdated.

10. Could local solutions answer global problems? While Switzerland and Sweden have been leading the way in Europe by developing solutions to managing these chemicals, the United States have been less responsive. The panelists agreed that Minnesota might be a good place to start, thanks to its trifecta of environmentally informed citizens, corporations and legislature.

Oil and gas extraction drives ecosystem lossPhoto by Jeff Wallace (Flickr/Creative Commons)

Present-day oil and gas extraction practices drive the large-scale loss of ecosystem services across the North American Great Plains.

That’s the take-away from a new study published today in Science co-authored by a University of Minnesota Institute on the Environment researcher. Improved drilling technologies coupled with energy demand has resulted in an average of 50,000 new wells drilled per year in central North America — displacing an area of crop- and rangeland equivalent to three Yellowstone National Parks between 2000 and 2012.  Continue reading

What’s the most interesting thing you’re reading now?

I am currently reading Capital in the Twenty-First Century, by Thomas Piketty (along with just about everyone else . . .). I love the fact that, through his own admission, the book is as much a contribution to our understanding of economic history as illuminating key dynamics shaping wealth and inequality. Our understanding of big thorny problems and our ability to implement potential solutions are rarely isolated within individual fields of study or areas of practice. His interpretation of the societal, political and economic balancing act dictating the roles of income and capital across countries is fascinating. Continue reading

Study: Plants’ ability to absorb CO2 limitedPhoto by César Viteri Ramirez (Flickr Creative Commons)

Does more atmospheric carbon mean bigger plants?

Not necessarily, according to a new study co-authored by a University of Minnesota Institute on the Environment researcher. Most climate scenarios, including those of the Intergovernmental Panel on Climate Change, assume that, since plants convert carbon dioxide to food for growth, more CO2 in the atmosphere will accelerate plant growth, thereby reducing the net amount of this greenhouse gas in the atmosphere. This study supports a growing body of knowledge that suggests instead that plants can’t keep absorbing more CO2 because there aren’t enough nutrients in the soil to sustain their growth.  Continue reading

6 things we learned about managing pandemic threatsFlickr: Photo by Matthew Anderson (Flickr/Creative Commons)

The April 15 Frontiers looked at ways we can manage disease threats at home and abroad. Thanks to a diverse panel including Patsy Stinchfield, director of infection prevention and control at the Children’s Hospitals and Clinics of Minnesota; Cheryl Robertson, an associate professor in the School of Nursing, and John Deen, a professor of Veterinary Population Medicine, here are six things we learned:

1. The nature of infectious diseases. In 2014, Ebola made headlines around the world, bringing fear and uncertainty with it. Prior to this, the disease had primarily occurred in rural areas with little contact with other communities, and so was relatively contained. But as Ebola started to make its way into larger cities and cross international boundaries, it sparked new conversations about how to manage the uncertainties and left many feeling unprepared. And, while Ebola may be the most notorious infectious disease right now, it is not the only one we need to worry about. The speakers also addressed measles, and the often-underrated influenza.

2. Prevention is better than reaction. As the Ebola crisis grew, the United States scrambled to prepare, often while facing serious public criticism. Stinchfield discussed how the Children’s Hospitals and Clinics of Minnesota took steps to become one of the most prepared hospitals in the country by simulating labs, learning how to handle waste and spending time making sure staff felt comfortable about their own personal protection. While the hospital hasn’t had to deal with a real Ebola case, the preparation did come in handy during a couple of potential cases. It also opened up conversations about preparing for the next outbreak.

3. The war on infectious diseases. Part of the problem is not the disease itself, but our ability to respond to it. Many countries that suffer the most are dealing with difficult social and cultural problems. Robertson, who has spent time in Liberia and a significant portion of her career addressing public health in conflict situations, compares the damage of infectious diseases to that of a war zone. Having the capacity to be completely prepared for these situations requires access to tangible resources as well as to intangible resources such as education. It’s hard to build a resilient health care system when professionals are leaving areas for their own safety and schools are closing. Moving forward, we need to think about the varied challenges that come with handling infectious diseases around the world.

4. It’s a learning process. While we’ve made strides in learning about infectious diseases and how to treat them, there is room for improvement. In 1989 and 1990, the United States struggled with a measles resurgence. At that time, it was practice to administer only one dose of vaccine, but researchers realized that this left 5 percent of the population vulnerable. Now medical professionals administer two doses of the vaccine, helping to raise the success of the vaccine to 99 percent. Such continued discovery will be important as the changing global landscape changes our interactions with diseases.

5. We are victims of our own success. Vaccines have been so successful that we’ve started to become desensitized to their impact. No longer having to see the direct impacts and physical manifestations of the diseases, we’ve lost the fear associated with them. Now the fear of the vaccine has begun exceeding the fear of the disease itself. As Deen pointed out, we almost need some level of fear of the diseases in order to remind ourselves to act.

We are one global community. One of the most important things to remember is that we’re all connected and we need to think on a global scale. Prevention in one part of the world helps prevent problems in other parts. To solve big problems, we also need solutions from across communities, nations and disciplines. This thinking can apply beyond infectious diseases and could be one way to approach our current environmental challenges too.

What was your biggest ah-ha moment?

The realization a number of years ago than humanity now dominates many of the chemical, physical and biological processes that make this world habitable, while at the same time the planet is now home to the healthiest, wealthiest, best educated, and most innovative, creative and connected populace in history. The future of Earth will be determined by human decision making, either by default or by design, by accident or by intention.

What is your current favorite project?

I am passionate about several new projects that I am pursuing. The Observatory will be a new exhibit for long-term display at the Science Museum of Minnesota that will provide visitors with novel opportunities by which to examine the world around them and in so doing collect scientific observations that help protect and enhance Minnesota’s environment. The Exergy Project seeks to use the museum itself as a model of advanced building energy efficiency to demonstrate how large commercial, institutional and industrial buildings could cost-effectively and substantially reduce their energy consumption. The Great Cities Initiative seeks to develop a major new exhibit for tour around the U.S. about the past, present and future of cities.

What gives you hope?

The accelerating pace of innovation of all kinds, which defies the contention by skeptics that addressing humanity’s many global environmental challenges are beyond our collective wherewithal.

What’s the strangest thing that has happened to you?  

I had the opportunity in January 2009 to be a member of a University of Minnesota research expedition to the McMurdo Dry Valleys of Antarctica — one of the coldest, driest, windiest places on the planet. Camping for nearly two weeks in a landscape completely devoid of visible life was a daily poignant reminder of how verdant and precious the rest of our planet is. Earth is an oasis in space.

What’s the one personality trait you rely on most often? 

Perseverance.

Bacteria tapped for water clean-upPhoto © BartCo (iStock)

This article was written by Kevin Coss and originally published in Inquiry.

Water plays a crucial role in industry. It helps us generate electricity and mine for precious minerals, and supports numerous other functions that fuel the economy and provide society with the products and services essential to everyday life.

During industrial use, however, water is sometimes contaminated by one of over 100,000 chemicals used commercially. If these chemicals are untreated, they can pollute the environment and create health risks for humans and animals. Industry leaders are continually seeking smart, cost-efficient ways to clean up after themselves and minimize their company’s environmental impact.

Now, a collection of scientists and business experts at the University of Minnesota are developing new methods of remediation — the act of removing pollutants from the environment. The researchers are developing software that models how enzymes break down chemicals at the microscopic level to optimize the selection of bacteria that biodegrade those chemicals. Meanwhile, business experts are conducting market research to discover the best ways to apply this new knowledge and learn how it can lead to viable industrial processes and products.

The project is part of the state-funded MnDRIVE Transdisciplinary Research Program, where researchers from different departments work beyond the limits of their disciplines to address complex challenges.

“Predicting how bacteria and chemicals will interact has historically been very challenging,” says Larry Wackett, professor with the U’s BioTechnology Institute, Institute on the Environment resident fellow and lead researcher on the project. “For the first time, RAPID, a novel software program, will use established biological principles to generate models that show how millions of chemicals can be optimally biodegraded. This idea has enormous potential for the world of bioremediation.”

Scientists have long known that microbes naturally found in water and soil will “eat” certain chemicals. Some companies place water that has been used in industrial processes into manmade ponds or large metal tanks which contain the appropriate type of bacteria to eat the contaminants in the water. But in many cases, the natural biodegradation processes do not work or they work too slowly.

That’s where Wackett and his team come in. Wackett and coworkers are developing an algorithm he calls the “Google of bioremediation.” RAPID, short for Reactive Activity Product IDentification, is designed to allow users, such as chemical developers or companies that produce industrial waste, to type in a particular chemical and quickly receive information on which species of bacteria are likely to break down that chemical. The system stems from the established U of M–designed Biocatalysis/Biodegradation Database, which shows the stages molecules go through as they break down.

Using the bacteria recommended by the system, scientists will be able to develop tests that quickly and accurately detect harmful chemicals, along with treatments that remove those chemicals from water. They will also be able to run a new chemical product through the system to see what bacteria and enzymes biodegrade it, allowing industry to develop safer, more environmentally friendly products. A chemical company could run a new herbicide through the system, for example, to see if it leaves behind any byproducts that are hazardous to humans or animals.

One example of bacterial remediation that has been successful is a process called “activated sludge,” used in municipal water treatment plants to clean up water that eventually will be processed for drinking. The procedure uses a collection of bacteria to filter out a wide range of impurities, including agricultural runoff, chemicals from personal care products like shampoo and organic matter from plants and animals to make the water safe for consumption. Outside of engineered water treatment systems, bacteria are also helping to retroactively clean up chemicals previously thought innocuous that now threaten to contaminate groundwater.

Finding the Niche for Breakthrough Treatments

While Wackett works on refining the hard science behind the RAPID system, a business team is exploring different approaches to marketing that knowledge.

Tobin Nord, professional director of the Ventures Enterprise at the Carlson School of Management, guides MBA students as they work with departments across the University to figure out how to commercialize new knowledge. Working with the scientific groups headed by professors Wackett, Alptekin Aksan, Mikael Elias, Carl Rosen and Carrie Wilmot, Nord’s team is pinpointing the remediation solutions most likely to succeed in the market and developing plans to launch technology based on them.

“Even the most innovative technology can’t reach its full potential if there isn’t someone willing to pay for it,” Nord says. “Our goal is to understand where environmental conservation and business needs intersect, and cater to those opportunities with research-based solutions.”

To find the best opportunities for commercialization, Nord’s team is assessing which individual chemicals hold the largest market potential. Their process for evaluating chemicals — both those known and those as-of-yet undiscovered — takes into account how widespread a problem it is, the effectiveness of any treatment methods that already exist and who would be likely to invest in cleaning it up. Each chemical is different; in some cases, an existing method can remove it at a reasonable cost, while in others, current industry practices are expensive and inefficient.

As an alternative, Nord’s team will also examine whether the RAPID technology would be best used as a consulting service for industry. Under that model, companies would come to the university with a specific chemical they want to treat, and the RAPID system would help researchers determine what type of bacteria and treatment system is optimum for their purposes.

Collaborating on Conservation

To take on a problem as complex as chemical contamination, Wackett and Nord are working with researchers from across academic disciplines. Aleptekin Aksan, Ph.D., mechanical engineering professor with the College of Science and Engineering and the BioTechnology Institute, is researching ways to scale up production of silica spheres — a sponge-like type of sand that can trap bacteria in place while contaminated water flows through, helping ensure bacteria evenly remove chemicals from the water.

Also working on the project are Mikael Elias and Carrie Wilmot both professors in the Department of Biochemistry, Molecular Biology and Biophysics in the College of Biological Sciences and members of the BioTechnology Institute. Elias is studying how bacteria evolve to eat certain chemicals, while Wilmot is using X-ray crystallography to study the structure and function of the enzymes that bacteria use to break down industrial chemicals.

Meanwhile, Carl Rosen, professor in the Department of Soil, Water and Climate in the U’s College of Food, Agricultural and Natural Resource Sciences, will identify which chemicals are most likely to contaminate the food supply. Through his research, Rosen will help researchers develop products that food producers and consumers alike can use to test food, which can help cut down on foodborne illness and eliminate the need to discard healthy food out of precaution.

“This is the spirit of MnDRIVE,” Wackett says. “We are connecting researchers from across the University and forming new partnerships with industry to tackle a host of real-world problems.”

This project is supported by MnDRIVE, a landmark partnership between the University and the state of Minnesota that aligns areas of University strength with the state’s key and emerging industries to advance new discoveries that address grand challenges.

Population control. We are overpopulating and exploiting the Earth and these are at the root of all environmental problems. I do not know how many people a sustainable world can support, but I suspect that it is less than a population of 9 billion. Continue reading

7 things we learned about social media & environmentFlickr: Photo by Kris Olin (Flickr/Creative Commons)

This week Brent Hecht, an assistant professor in the College of Science and Engineering, and Spencer Wood, senior scientist with the Natural Capital Project at Stanford University, joined Frontiers in the Environment to discuss how social media can be used to inform the causes and consequences of environmental change. Here are seven things we learned:

1. We’ve entered a new era of data. The explosion of social media has created an abundance of data not previously available. Geotagged information (the inclusion of geographical information on forms media, such as marking your location in a Tweet) from social media is one way to harness these data in a useful way. Using the combination of location information in conjunction with the information included in the post, researchers can gleam new insights. Continue reading

We need system change, not regulationPhoto © franckreporter

This article was originally published in The Conversation.

The higher levels of heat-trapping gases from burning fossil fuels are one feature of what many call the Anthropocene, a new geological era dominated by humans.

Yet regulatory approaches to managing carbon in the Earth system are doomed to fail. This is because the rise of carbon dioxide levels — what I call the CO Catastrophe — is taking place at the scale of the Earth system itself. Humans are inside of that system, COemissions are coupled to energy use, and increasing energy use is central to economic advancement. I have become convinced that it is simply not possible to manage energy usage from the scale of households to that of the planet itself using regulatory methods. Continue reading

Carver County is new RCP partnerPhoto by Ann Wiechmann (Flickr Creative Commons)

Carver County, one of seven counties in the Twin Cities metro, has been chosen as the 2015–16 Resilient Communities Project partner. Enhancing bike and pedestrian facilities near park-and-ride locations, evaluating stormwater reuse opportunities, crafting an ecotourism marketing plan and exploring opportunities for preservation of a historic farmstead are among the 34 projects the county will tackle with help from University of Minnesota sustainability expertise.

RCP organizes yearlong partnerships between the University and Minnesota communities. The partnership will bring the expertise of hundreds of graduate students to sustainability-related projects identified by Carver County staff and community partners.

“We’re very excited about our upcoming partnership with Carver County,” said RCP director and Humphrey School of Public Affairs associate professor Carissa Schively Slotterback in a press release. “The enthusiasm of staff from the county and its partner cities and organizations as well as their clear commitment to advancing sustainability and resilience will ensure a productive and enjoyable collaboration that will benefit Carver County and provide community-engaged learning opportunities for University of Minnesota students.”

Carver County will be the fourth RCP partner in as many years. Previous partners have been the City of Minnetonka, North St. Paul and Rosemount.

The Resilient Communities Project is an initiative of the Sustainability Faculty Network at the University of Minnesota, with funding and administrative support provided by the Center for Urban and Regional Affairs and the Institute on the Environment.

What is your current favorite project?

I’m working with colleagues at Cornell University to understand how and why the environmental “stories” recorded by trees differ from place to place. Every year, trees in Minnesota and other parts of the world with strongly seasonal climates form a new layer of wood around their stem. That layer of wood — a tree ring — is very clear evidence of the passing of time and records, indirectly, the immediate environment of that tree. Over the last several decades scientists have collected tree-ring records from hundreds of thousands of trees around the planet. A tree ring may be a very simple thing, but reading millions of them at the same time might tell us a great deal about the environmental past (and perhaps future) of our planet. Continue reading
