WASHINGTON, Sept. 1, 2016 � Odor-detecting devices like Breathalyzers have been used for years to determine blood-alcohol levels in suspected drunk drivers.

By tracking the chemicals in “old book smell� and other musuem odors, conservators can react quickly to preserve priceless art and artifacts at the first signs of degradation. In this Speaking of Chemistry, Sarah Everts explains how cultural-heritage science uses the chemistry of odors to save books, vintage jewelry, and even early Legos. Check out the video here: .
