SOT 2016 - Q&A with Cardno ChemRisk Scientists Part IV
Please read below for more information from Evan Beckett on his recent presentation, as we continue to spotlight our SOT 2016 presenters.
1. What was the title of your presentation?
The title of my poster was "Assessment of Indoor Formaldehyde Concentrations Following the Installation And Removal of Laminate Flooring."
2. What was the scope of your research?
In this study, we investigated the potential formaldehyde emission levels associated with the installation, use, and removal of laminate flooring. We also compared these emission levels to current regulator exposure standards, as well as published exposure thresholds associated with various health endpoints.
3. What did you find?
After the installation of the flooring products, average airborne concentrations of formaldehyde significantly increased compared to background levels. After the introduction of the flooring to a room, mean airborne concentrations exceeded the 8-hr and chronic Reference Exposure Level Recommended Exposure Limit (REL) and the Proposition 65 No Significant Risk Level (NSRL) set by California's Office of Environmental Health Hazard Assessment (Cal-OEHHA), as well as the FEMA procurement standard. Airborne concentrations at the end of the post-installation period were slightly above the lower end of the odor detection threshold range, but far below sensory irritation thresholds.
4. What are the next steps / what other research is needed?
In the future, longer-term studies may be useful to determine the potential impact that formaldehyde "sinks" has on the airborne concentrations over time. This information would be helpful in assessing the potential long-term risk associated with formaldehyde-containing flooring products.
For more information, please contact me. I would be happy to discuss this research further.
