The Center for Healthy Air, Water, and Soil is building a living, urban laboratory to support collaborative research and promote health in all policies approach to decision making at the University of Louisville. We bring people and data together to begin new conversations and find new solutions to health challenges in our community and around the world.
The Envirome Institute at University of Louisville’s School of Medicine engages researchers and citizen scientists to learn how our natural, social, and personal environments impact health. The Envirome’s faculty and research teams explore and work to understand the relationships between the environment and human health.
Indoor Air Quality:
“Plants produce their own food through a process called photosynthesis. This means they take in carbon dioxide from the atmosphere and release oxygen. Photosynthesis "cleans" our air by absorbing carbon dioxide and by taking in certain other pollutants as well. A team of National Aeronautics and Space Administration (NASA) researchers lead by Dr. Bill Wolverton tested the effect of fifteen house plants on three pollutants known to be present in spacecrafts. These same three pollutants--benzene, formaldehyde and trichloroethylene--are present in homes and office buildings. They occur because they are emitted from furnishings, office equipment and some building materials. The NASA researchers suggest that for the test plants to be effective "air cleaners" it is necessary to use 1 potted plant per 100 square feet of home or office space.” -Laura Pottorff, Cooperative Extension, Colorado State University
Where Can these Pollutants Appear?
Office
Common office materials like printing vapor, synthetic fibers of furniture and carpet, furniture glue, plywood, and particle board release formaldehyde, benzene, and xylene into the air. These chemicals can cause eye, ear, nose and throat irritation, increased heart rate, headache, asthma attacks. These plants can scrub your indoor air to increase work outcomes for the entire office.
Hospital
Every hospital patient deserves their own personal garden. Not only do plants promote healing, but a variety of airborne toxins such as ammonia, xylene, and formaldehyde, contaminate the indoor air of hospitals which can cause people to feel sick longer. These plants scrub the air of toxins from cleaning agents and other medical activities that are common in hospitals and other medical facilities.
Home
Our households are very busy places from the kitchen to the DIY project spaces. Kitchen activities and DIY projects cause airborne pollutants which can cause eye, ear, nose, and throat irritation and cough. Paper products like napkins and paper towels release formaldehyde and many cleaners contain ammonia. DIY projects can include the use of adhesives, sprays, glues, paints, and lacquers that release airborne toxins such as xylene, and trichloroethylene.

Trichloroethylene
- From printing ink, paint, lacquer, adhesives, paint remover
- Causes headache, dizziness, nausea
Ammonia
- In household or industrial cleaners and fertilizer
