Christmas Tree Emissions

Caption

NIST researchers placed a common type of Christmas tree in a sealed chamber for 17 days to monitor and measure the chemicals it emits. These chemicals called volatile organic compounds (VOCs) give that pine smell and can react with ozone to form byproducts. They found low amounts of these chemicals, which may be a potential concern for people who are sensitive to them.
