Over the last several weeks, people everywhere–including Iowa–have been increasingly encouraged or ordered to stay home in an effort to slow the spread of COVID-19. Below are three ways to keep caring for Mother Nature while you care for yourself and your community during these unprecedented times.

1. No paper towels? No worries

With mass panic-buying wiping store shelves clean in recent weeks and non-essential excursions strongly discouraged, some households may worry about fulfilling their regular demand for paper products.

While disposable paper towels are great for the messiest of messes, consider using reusable cloths and rags are a more eco-friendly option for household cleaning.

2. No need for bottled water

While stocking up on bottled water might be tempting, there is no reason to believe the pandemic will impact household tap water. The Iowa Department of Natural Resources released a statement encouraging Iowans to continue using tap water as much as they can.

3. Grow your own microgreens

Doing some indoor home gardening will not only keep you busy, but create a hyper-local produce supply you don’t have to venture to the store for. Growing microgreens –seedlings of edible plants– is among the easiest ways to get started.

Spread potting soil in a shallow tray (consider reusing packaging from a container of berries or salad mix) sprinkle a layer of seeds on top and cover with a very thin layer of soil. Kept in a sunny spot and sprayed with water to keep the soil damp, you can yield a microgreen crop every two weeks or so.

Sunflower, sweet pea and radish seeds (available online) are great options for getting started. The seedlings take on the flavor of the mature fruit or vegetable, making a great salad base or addition to other dishes. Get creative!

 

DNR confirms further spread of deer disease through Iowa

Forty-three deer killed by hunters and vehicles in Iowa during the 2019-2020 hunting season tested positive for chronic wasting disease, also known as “zombie deer disease.”

This brings the total number of confirmed cases in Iowa’s wild deer population to 89 since 2013, according to an Iowa Department of Natural Resources press release. That’s a 93% increase in one year.

Chronic wasting disease is a 100% fatal neurological disease found primarily in deer and elk that causes loss of bodily functions. An abnormal protein causes the infection, spread via bodily fluids from deer to deer. Some symptoms include excessive salivation, weight loss, listlessness and drooping ears and head.

The disease is in the same family as bovine spongiform encephalopathy, also known as Mad Cow Disease. The Centers for Disease Control reports that there is no conclusive evidence of the disease transferring to humans, but the center recommends avoiding contacts with infected venison.

The Iowa DNR collected samples from about 7,000 deer hunted or killed by cars across the state during the 2019-2020 hunting season. Samples from Woodbury, Winneshiek, Fayette and Decatur counties tested positive for the first time.

Officials have identified chronic wasting disease in wild deer populations in eight counties overall. Deer in several captive populations have tested positive as well (see this interactive map for more information).

AP story showcases tension in Iowa over factory farming

A news story published last week featured an Iowa farmer who illegally built to un-permitted barns containing about 2,400 hogs. State officials were unaware of the concentrated animal feeding operations (CAFOs) for years. 

That farmer and others are fighting in what Associated Press correspondent John Flesher called a “battleground” in Iowa. Questions of pollution and regulation have inspired lawsuits, anti-CAFO alliances and neighborly tensions throughout the state, as animal feeding operations continue to proliferate.

Below are four key takeaways from Flesher’s in-depth report. Read the full-length story on apnews.com.

  1. The federal government relies state data for animal feeding operation data. In many cases, states keep tabs on only the largest operations (in Iowa, a true “CAFO” has a minimum of 1,000 species-variable “animal units” per confinement). The EPA counted about 20,300 CAFOs nationwide in 2018.  The U.S. Department of Agriculture estimates there are about 450,000 animal feeding operations–places animals are raised in confinement (of any size)– nationwide.
  2. The Iowa Department of Natural Resources discovered thousands of previously undocumented animal feeding operations in 2017.  Some point to this case as proof of under-regulation, but state regulators said the discoveries indicated a well-functioning system.
  3. Under the 1972 Clean Water Act, especially large livestock operations need permits for discharging waste into waterways. Since such discharges are often unintended, however, state and federal environmental agencies can only mandate permits for operations caught discharging waste. In some cases, farmers have been able to make spill-proofing improvements instead of applying for permits.
  4. Studies show that livestock operations and anaerobically decomposing waste release massive amounts of ammonia and greenhouse gases. Because such emissions are difficult to measure, though, they are unregulated by the Clear Air Act. Studies have additionally correlated these emissions to human health issues such as childhood asthma. Cause/effect is impossible to prove, however.

CGRER’s Co-director Jerry Schnoor sat down with Iowa Public Radio to discuss what life with climate action would like and how Iowans can adapt their own lives with impending climate changes. We have already seen severe flooding and intense preciptations, but what’s next?  You can listen to learn more here.

Iowa American Water disputing forever chemicals found in Iowa water

Last week, a study by the Environmental Working Group, found PFAS in more than 40 locations in 31 states. One of those places being the Iowa Quad Cities. PFAS are known as “forever chemicals” because they never biodegrade. They are a man-made substance, used in products like nonstick cookware and other food packaging. Nearly 5,000 different chemicals are associated with the PFAS family but only a few have been studied. Researchers do not know the health effects of drinking water with contamination but they have been linked to certain cancers, liver damage, and low birth weight according to Reuters.

Iowa American Water is currently disputing report’s findings from a drinking sample taken in August in Davenport that revealed high levels of toxic chemicals.

“We want our customers to know that we are doing our job for them and that we are meeting all federal, us, EPA and state standards related to water quality. So they can be confident when they take that tap water and give it to a child or a family member that it is safe,” Lisa Raisen, External Affairs Manager for Iowa American Water, said to KWQC staff.

UI research links pesticide and cardiovascular death

New observational research has found that people with high exposure to common “pyrethroid” insencticides were 56% more likely to die during a study period than others. Cardiovascular disease was the leading cause of death in the exposed.

CGRER member Wei Bao, assistant professor of epidemiology in the University of Iowa College of Public Health, is an author of the study, published Jan. 30 in JAMA Internal Medicine.

Pyrethroid insecticides are used in most household insecticides and some pet products and head-lice shampoos. The study followed a sample of 2,116 adults who took the United States National Health and Nutrition Examination Survey between 1999 and 2002, representative of the U.S. population as a whole. The researchers noted levels of pyrethroid-associated chemicals in their urine and found death records to determine how many had died by 2015, as well as their cause of death.

While those with higher pyrethroid exposure were more likely to die overall, the highly exposed were three times more likely to suffer cardiovascular deaths than others as well.  Bao said in an Iowa Now feature that the study does not prove that the insecticides are the cause of death, only that death and exposure are correlated.

 

 

New UI research could help fight pollution with microorganisms

As pollutants like particulates, PCB and pesticides filter out of the air, they often accumulate on surfaces like asphalt or building exteriors. When it rains, the pollutants can run off into water sources.

University of Iowa researchers recently published findings in Earth and Space Chemistry, revealing that a variety of bacteria and fungi live within the film of pollution on such surfaces. Some of those microorganisms are able to digest and break down the pollutants.

Researchers Scott Shaw (chemistry) and Timothy Mattes (civil and environmental engineering) intend to sequence the DNA of these organisms in the future. They will then be able to determine which could potentially be cultivated for fighting pollution in other areas, according to Iowa Now.

CGRER, the UI Center of Health Effects of Environmental Contamination,  the U.S. Department of Defense Army Research Office and the Nuclear Regulatory Commission funded this research.
