Laminate Flooring Test Results - Health Issues and Solutions

"CDC/ATSDR was notified February 13 of an error in its report released February 10, 2016, about the possible health effects from exposure to formaldehyde emitted from select laminate flooring samples. Health risks of people who have the laminate flooring are being revised to reflect greater exposure to formaldehyde, which could cause eye, nose, and throat irritation for anyone. The estimated risk of cancer associated with exposure to the flooring increased.

The CDC/ATSDR indoor air model used an incorrect value for ceiling height.  As a result, the health risks were calculated using airborne concentration estimates about 3 times lower than they should have been.  The original report found:

• Exposure to the low end of the modeled levels of formaldehyde in indoor air could cause increased frequency of asthma symptoms and other respiratory issues for people with asthma and COPD;
• Exposure to the higher-end levels could result in eye, nose, and throat irritation for anyone; and
• Low risk of cancer (2-9 cases per 100,000 people).

After correcting the measurement in the model, CDC/ATSDR is revising the possible health effects. The final results are not yet available, but are estimated to be closer to these:

• Exposure to the range of modeled levels of formaldehyde in indoor air could cause increased symptoms and other respiratory issues for people with asthma and COPD;
• Exposure to the lowest modeled levels of formaldehyde could result in eye, nose, and throat irritation for anyone; and
• The estimated risk of cancer is 6-30 cases per 100,000 people. Because of the very conservative (health protective) nature of the models used in this analysis, ‎the calculated risk is likely lower than our modeled estimate..."
