Written by Sarah Feehan, Communications Specialist

AMES, IOWA – The Iowa Water Center (IWC) annually administers a statewide grant competition known as the IWC Graduate Student Research Competition.

The purpose of this funding is to enable graduate students to complete additional research objectives beyond the scope of their current work, with an emphasis on submitting their research to peer-reviewed publications.

Hui Zhi has been selected among three other graduate students from across Iowa. She and the other recipients will receive funding for a variety of proposed research.

Zhi’s proposed research encompasses sorption and biodegradation of pharmaceuticals in Iowa’s water. It is titled ‘Quantifying Differential Sorption and Biodegradation of Pharmaceuticals in a Wastewater Effluent-dominated Stream in Iowa’.

Associate Director of the IWC Melissa Miller says, “Water Resources Research Institutes like the Iowa Water Center were authorized by Congress in part to address emerging water resources concerns through research. The fate and transport of pharmaceuticals in our water is of critical interest to both the state and region, and we look forward to sharing the results of Ms. Zhi’s work.”

“From this research, we’ll better understand the fate and transformation of pharmaceuticals in the surface water. It’s important we understand what’s in our drinking water, what’s in the treated wastewater, and what’s in the streams and rivers. And, how they change spatially and temporally,” Zhi says.

Typically, Zhi wakes up around 6:30 A.M. and makes herself breakfast and a cup of black coffee. Once at her office, she checks emails and reads journal article updates.

One early morning in her office, Zhi received an email about the IWC’s grant competition and thought, “it would be a really great opportunity to apply for.” She spoke to her adviser about the competition and he encouraged her to write and submit a proposal.

“It caught my eye,” Zhi says of the grant competition email. Zhi’s research from this grant work will be a one-year study that employs both field and laboratory research approaches.

Zhi says, “I really enjoy working in the lab and look forward to getting the results.”

Zhi grew up in China, where she completed her bachelor’s degree in an environmental science program at China Pharmaceutical University.

The environmental crisis in China influenced Zhi to continue school and to focus on environmental engineering. She decided to continue her studies here in the United States, where Zhi believes, “the best programs in the world for environmental engineering are at.”

She received her master’s degree at Cornell University and is now a PhD candidate at the University of Iowa. Her anticipated completion year is 2020.

With her research, Zhi hopes people will better understand the behaviors of pharmaceutical mixtures in the water and their associated ecological impacts.

She explains, “The results will be able to help the right people, whoever is responsible for our water policy regulations, set in place science-based water quality regulations for pharmaceuticals. Regulations not just for our drinking water, but also in the treated wastewater that is discharged into our environment. Hopefully then, we will have a cleaner water environment.”

Instead of just focusing solely on the quality of our drinking water, Zhi thinks knowing what’s going on in all our water systems, for example streams and rivers, is vital to a healthy environment.

Pharmaceuticals can have impacts on aquatic species, such as fish, living in the water. If pharmaceuticals are accumulating in fish and people are eating these fish, the accumulation of pharmaceuticals ends up in human bodies.

Therefore, not only are we drinking pharmaceuticals, but we are also eating fish that have been accumulating pharmaceuticals over time. “People need to know what’s happening in the streams nearby that they’re swimming in and also in the waters their fish are found because there are potential impacts on the human body that we don’t clearly know yet,” Zhi says.

To help prevent research burnout, Zhi enjoys exercising. “Whether it’s cardio, yoga, boxing, rock climbing, or swimming, I love it. All these different sports help relieve any pressure from research, and I have a lot of fun doing them,” Zhi says.

AMES, IOWA – The Iowa Water Center (IWC) annually administers a statewide grant competition known as the IWC Graduate Student Research Competition.

The purpose of this funding is to enable graduate students to complete additional research objectives beyond the scope of their current work, with an emphasis on submitting their research to peer-reviewed publications.

Tania Leung has been selected among three other graduate students from across Iowa. She and the other recipients will receive funding for a variety of proposed research.

Leung’s proposed research encompasses harmful algal blooms and cyanobacteria in Iowa’s waters. It is titled ‘Determining the Effects of Co-Nutrient Availability on Harmful Algal Blooms Across Varying Lake Types’.

Associate Director of the IWC Melissa Miller says, “Water Resources Research Institutes like the Iowa Water Center were authorized by Congress in part to address emerging water resources concerns through research. Ms. Leung’s research investigates a question that water professionals in this region posed during a recent public discussion on harmful algal blooms.”

“I’m most looking forward to are the results of this research,” Leung says. “For example, do iron concentrations vary from lake to lake? And if so, why? Is it geologically impacted or not? And if these iron concentrations do vary from lake to lake, then the next question: Do these harmful algal blooms also vary in terms of how intense they are? And if they are very intense, do the toxins vary?”

Miller says, “This is an excellent example of the value of creating feedback loop between the research community with professionals and engaged citizens in order to rapidly respond to pressing issues.”

Get to Know Tania Leung, PhD Candidate at Iowa State University

Leung is from a small town in southern Florida about 5 or 6 hours north of Key West called Lauderhill. She received both her bachelor’s and master’s degrees at Florida Atlantic University.

During her master’s, Leung discovered her passion for water quality and decided to pursue this interest with a PhD in geology and environmental sciences at Iowa State University (ISU).

“I always knew I wanted to do a PhD, but I just didn’t know where. So, I started my research by looking for professors who shared similar interests as me regarding water quality,” says Leung. She found what she was searching for.

Tania Leung and Research Work

“There was a professor at ISU who had a project that was looking into harmful algal blooms. She was trying to see if the iron content or concentrations in the lake water contribute to harmful algal blooms.”

Coming from Florida, Leung was familiar with widespread harmful algal blooms along the coast. However, she hadn’t heard of these blooms being inland until she came to ISU. She says this inland perspective in Iowa has given her, “new insight.”

Leung’s adviser, Elizabeth Swanner, saw on Twitter back in September a tweet about the IWC’s Graduate Student Research Competition. Swanner then ran the idea by Leung.

“Well I never thought a tweet of all things,” Leung says. “Normally I think we as graduate students look for agencies that are looking for grants that we can apply to, but this is interesting that my adviser saw something on Twitter. That was a fun and surprising moment when she told me that.”

One of Leung’s favorite hobbies is cooking. “I took up cooking during my master’s. I love trying new recipes and figuring out what works and what doesn’t,” Leung says.

Long-term crop rotation and tillage effects on soil greenhouse gas emissions and crop production Illinois, USA (Research Summary)

Post submitted by Tianna Griffin, the Iowa Water Center’s Special Projects Assistant

A recent article by Behnke et al. (2018) evaluates the long-term effects of crop rotation and tillage practices on yield and greenhouse gas emission for corn (C), soybeans (S), and wheat (W). The rotations were CCC, CS, CSW, SSS, SC, WCS, with each rotation representing one year. Each rotation had a tilled (T) and no-till (NT) treatment. The study was conducted using a 15-year time span at the Northwestern Illinois Agricultural Research and Demonstration Center.

Behnke, et al’s research evaluated tillage practices and crop rotation on yield, greenhouse gas emission, and soil available Nitrogen (N). Behnke et al. hypothesized that crop rotations where less N fertilizer is used would result in lower greenhouse gas emissions, specifically nitrous oxide (N2O). They predicted that chisel tillage would cause an increase in N2O and CO2 (carbon dioxide) emissions caused by mineralization of decomposing residues (Behnke, et al 2018). From 2012-2015, greenhouse gas emissions were taken weekly during a period of four growing seasons. The data was grouped into three sets of sampling months: March-May, June-August, and September-November. Putting the data into groups allowed for analysis of seasonality on greenhouse gas emission. Soil samples were also taken from the 2013-2015 growing year to evaluate N concentrations.

A main finding of the study was that there wasn’t a significant difference on greenhouse gas emissions between continuous corn with tillage and continuous corn with no till. They found that there was a significant benefit of chisel tillage to corn and soybean yield in increasing organic matter and residue, but there was no increase of N2O and CO2 in the soil found in the study. Because corn typically benefits from high amounts of N, they observed that corn being part of a rotation was able to lower the amount of N2O in the soil. An important part of the research was that N2O emissions were higher at times of fertilizer application. During fertilizer application is when pollution (water and air) is more likely to occur. When fertilizer is applied in excess, plants don’t take up all of it; what is not taken up by the plant is volatilized (when a chemical converts to a liquid or gas) and/or runs off the field. Yields were higher with a diverse crop rotation, such as CS or CSW. Having a diverse cropping system also provides resiliency in yield during suboptimal weather conditions.

Agricultural practices are responsible for a lot of the pollution that occurs in the United States. According to Behnke et al. (2018), greenhouse gases emissions due to agricultural practices in the Unites States makes up 9% of the emitted greenhouse gases. Of that 9%, 81% is CO2, 11% is NH4 (methane), and 6% is N2O. Long-term research like this study can help evaluate ways to mitigate greenhouse gas emissions as well as determine the effects of some agricultural practices on greenhouse gas emissions as well as on improving yields. This research may lead to more long-term research on agricultural practices.
