Our team at the Toxicant-Induced Loss of Tolerance (TILT) Program at UT Health San Antonio wanted to share this important open-access study:
“Preliminary Study on the Emission Dynamics of TVOC and Formaldehyde in Homes with Eco-Friendly Materials: Beyond Green Building” from researchers at Ajman University and University of Sharjah.
The study, in the journal Buildings, analyzed the concentration changes over time in the living rooms of experimental units to assess the effectiveness of eco-friendly materials in reducing indoor air pollutants, including the emission characteristics of formaldehyde (HCHO) and total volatile organic compounds (TVOC).
The results show that eco-friendly materials exhibit lower initial emissions of TVOC than general materials, gradually decreasing over time. Compared to the eco-friendly material unit, the general material unit takes longer to reach acceptable TVOC concentrations. The emission pattern of HCHO differs from TVOC, with the highest peak occurring on the seventh day. Major individual VOCs, except for benzene, exhibit a similar decreasing trend for TVOC over time. Eco-friendly materials demonstrate significant reductions in emissions compared to general materials in various material applications, including parquet flooring, wallpaper, built-in furniture, and kitchen furniture.
These findings emphasize the effectiveness of eco-friendly materials in reducing indoor air pollutants and provide valuable insights for creating healthier living environments.
Indoor air quality is important for people who suffer from chemical intolerance (CI), said Dr. Claudia Miller, allergist/immunologist, professor emeritus, and leader of the Hoffman TILT Program at UT Health San Antonio.
How can you find out if you are chemically intolerant?
Answer these three questions from Hoffman TILT’s Brief Environmental Exposure and Sensitivity Inventory (BREESI):
- Do you feel sick when you are exposed to tobacco smoke, certain fragrances, nail polish/remover, engine exhaust, gasoline, air fresheners, pesticides, paint/thinner, fresh tar/asphalt, cleaning supplies, new carpet or furnishings? By sick, we mean: headache, difficulty thinking, difficulty breathing, weakness, dizziness, upset stomach, etc.
- Are you unable to tolerate or do you have adverse or allergic reactions to any drugs or medications (such as antibiotics, anesthetics, pain relievers, X-ray contrast dye, vaccines or birth control pills), or to an implant, prosthesis, contraceptive chemical or device, or other medical/surgical/dental material or procedure?
- Are you unable to tolerate or do you have adverse reactions to any foods such as dairy products, wheat, corn, eggs, caffeine, alcoholic beverages, or food additives (e.g., MSG, food dye)?
If you answer YES to any of these three questions, take the Quick Environmental Exposure and Sensitivity Inventory (QEESI) and share the results with your doctor!
