Climate and health experts discuss effects of climate change on Iowans


Nick Fetty | November 4, 2014

The 2014 Iowa Climate Science Educators Forum took place on the University of Iowa Oakdale Campus in Coralville on Friday, October 31. The 2nd annual event was attended by approximately 50 climate and health experts from across the state.

Chris Anderson - Assistant Director Climate Science Program at Iowa State University – was the first to present at Friday’s event as he discussed the impact of climate change in Iowa.

“Climate change in Iowa is different from climate change on TV,” he said.

One example of this is the frequency of spring and summer rainfall combinations. There were approximately seven instances of spring and summer rainfall combinations between 1893 and 1980 compared to five instances between 2008 and 2014.

Mary Spokec – research geologist and program coordinator for IOWATER – along with David Osterberg – Associate Clinical Professor of Environmental Policy in the University of Iowa’s Department of Occupational and Environmental Health  - took the stage next to discuss water quality issues related to climate change. They said part of the reason for toxic algal blooms which can lead to water contamination is because there are no national standards for algal cyanotoxins.

This issue can be particularly problematic in Iowa other agricultural states where nitrogen and phosphorus can runoff of fields and into waterways which exacerbates the growth of hazardous algal blooms such as blue green algae. Extreme weather associated with climate change has also affected these algal growths. According to weekly monitoring of 38 state-owned beaches, there were 46 water quality advisories during 2013 and 2014 compared to seven in 2011 and two in 2010.

Peter Thorne – head of the UI’s Department of Occupational and Environmental Health – presented next about climate-induced air quality issues affecting Iowans. Molds such as Aspergillus and Penicillium can grow on damp wood in houses and other structures that sustain flood damage. This can lead to a range of pulmonary conditions including mold allergies, asthma, inflammation of mucous membranes, Katrina cough, and Alveolitis. Climate change has also been attributed to more extreme weather events such as heavy rain falls which can lead to flooding.

Increased carbon dioxide levels, hotter temperatures, and a longer growing season (each of which can at least partially be attributed to climate change) is causing poison ivy plants to be more potent. Other allergenic plants have also seen increases in potency as well as an expanded range because conditions attributed to climate change.

Yogesh Shah – Associate Dean of Global Health at Des Moines University – discussed how has climate change has effected disease-carrying insect populations.

“This is the most deadly animal around,” Shah said of mosquitoes, adding that the disease-carrying insects have killed more humans than all other animals combined.

Approximately 600,000 deaths occur each year because of mosquitoes and reported cases of malaria are the greatest they’ve been since 1971. A relatively unheard of disease known as Chikungunya is on the rise, particularly in areas of Africa, India, China, and other parts of southeast Asia. Around 750,000 cases of Chikungunya have been reported in Caribbean and some cases have moved as far north into Florida and other parts of the U.S.

Two cases of Chikungunya has been reported in Iowa by people who contracted the disease while traveling. West Nile Virus is also carried by mosquitoes and in 2002 there were cases of either human or non-human WNV reported in every county in Iowa. Warmer temperatures and a longer growing season have also led to greater numbers of longer-living mosquitoes.

Peter Thorne concluded the morning session by discussing mental health affects caused by increased heat and particularly warmer nighttime temperatures. The group then broke for lunch and spent the rest of the afternoon participating in a public health tracking portal presented by  environmental epidemiologists Tim Wickam and Rob Walker from the Iowa Department of Public Health.

Many of the public health and environmental issues discussed at Iowa Climate Science Educators Forum were included in the Iowa Climate Statement 2014: Impacts on the Health of Iowans.

This week’s On the Radio segment looks at a website that’s helping Iowa farmers tackle environmental challenges on the farm. Listen to the audio below, or continue reading for the transcript.

Transcript: AM-PAT

An Iowa State University Extension and Outreach website provides livestock producers with the tools to better handle environmental challenges on the farm.

This is the Iowa Environmental Focus.

The Air Management Practices Assessment Tool – or AM-PAT – aims to assist livestock farmers with mitigation practices to better deal with the odor, exhaust and dust associated with livestock and poultry operations.

Users can view and print off color-coded graphs and fact sheets to gauge pollutants like ammonia, hydrogen sulfide, dust, odor, volatile organic compounds, and greenhouse gases and how they affect various aspects of livestock operations. The website also calculates the relative cost for the various practices.

AM-PAT is a collaboration between the Iowa State University Extension and Outreach and the College of Agriculture and Life Sciences with funding provided by the National Pork Board.

For more information about AM-PAT and other resources, visit IowaEnvironmentalFocus.org.

Flood sensor expansion continues

The Iowa Flood Center is dramatically expanding the scope of its river and stream sensor network across the state this fall.

The Flood Center, which has installed 200 river and stream gauges since 2010, will add an additional 50 sensors in collaboration with the Iowa Department of Natural Resources. These gauges monitor water levels in real time and send the data back to the Iowa Flood Information System (IFIS), which can be viewed by the public. Citizens, landowners and governments can then use this web-based tool to look for flood warnings, monitor water levels upstream from their location, and see exactly how far flood waters will reach in a given situation.

The sensors, which are usually installed on bridges, measure the distance to the water by sending an electronic pulse every 15 minutes. The availability of such precise measurements has already had a significant impact on local businesses, especially those located in floodplains. The sensors, which cost around $3,500 each, can save businesses thousands more by preventing losses in production and labor during flood season.

Iowa Flood Center staff and students will install the new sensors over the coming weeks. Watch the video below to learn more about how these sensors are installed across the state.

Study: Vitamin B12 may be key to removing PCBs, other toxins released into environment

A 15-year study by researchers at the University of Manchester finds that vitimin B12 could be the key to removing PCBs and other harmful pollutants already released into the environment.

“We already know that some of the most toxic pollutants contain halogen atoms and that most biological systems simply don’t know how to deal with these molecules,” University of Manchester professor David Leys said in a press release. “However, there are some organisms that can remove these halogen atoms using vitamin B12. Our research has identified that they use vitamin B12 in a very different way to how we currently understand it.”

The team from the Manchester Institute of Biotechnology used x-ray crystallography to study 3D models of how halogen atoms are removed from organisms. These particular organisms are “microscopic deep sea creatures” which are also found in rivers and ponds.

While humans use vitamin B12 to maintain a functioning brain and nervous system, certain micro-organisms and bacterium are able to use it as a detoxifying agent. The rapid reproduction rate of these bacterium means they can remove “a huge quantity of chemical in a few weeks.”

Often times these toxins pollute the air and the water through direct disposal onto land and waterways as well as through burning household waste.

The study was published this month in the journal Nature. The project was made possible with funding from the European Research Council.

Transcript: Climate Statement 2

Climate change causes extreme weather, increased flooding and resulting water pollution, which is threatening the health of Iowans.

This is the Iowa Environmental Focus.

The Iowa Climate Statement 2014: Impacts on the Health of Iowans, released in October, examined how repeated heavy rains and the resulting flooding have led to increased exposure to toxic chemicals and raw sewage, which can have negative effects on health for humans and animals.

The fourth annual statement was signed by 180 scientists and researchers from 38 colleges and universities across Iowa.

Heavy rains in agricultural areas causes phosphorus and nitrates to run off fields and into waterways. These polluted waterways coupled with increased water temperature have spurred algal blooms on still bodies of water during peak summer heats. These algal blooms make the water unsafe for human or animal consumption or recreation.

A report released by the United States Geological Survey last month suggests that pharmaceuticals and other potentially hazardous substances from treated wastewater can contaminate shallow groundwater after being released into streams and other waterways.

The research was conducted on Fourmile Creek and Watershed near Des Moines in 2012. In October of 2012 wastewater accounted for 99 percent of the creek’s flow and this number dropped to 71 percent in December 2012. During these months, the creek experienced persistent dry conditions which is when contaminates are most likely to seep into groundwater.

The study tested for 110 different pharmaceutical compounds in addition to hormones and chemicals from personal care products. The researchers concluded that between 48 and 61 pharmaceuticals were present in the water tested downstream from the wastewater discharge point. Concentrations were as high as 7,810 parts-per-trillion for metformin, a chemical used in antidiabetic medication.

This contamination was also taking place in groundwater up to 65 feet away from the banks of Fourmile Creek. Between 7 and 18 pharmaceutical compounds were detected in these groundwaters with concentrations of fexofenadine - an antihestemine – as high as 87 parts-per-trillion.

This study was part of USGS Toxic Substances Hydrology Program.

The Fourmile Creek Watershed covers 120 miles mostly in northern Polk County but also areas of Boone and Story Counties. Approximately 64 percent of the land in the watershed is used for agriculture while the remaining 36 percent is urban. In 1877, a train carrying members of the P.T. Barnum circus and other passengers crashed while crossing over Fourmile Creek, killing 20 and injuring 35 more.
