Can kindergarten classroom materials expose kids to plasticizers?

What plasticizers are
Plasticizers are chemicals added to plastic to make it soft and flexible. Common examples include phthalates such as DEHP, plus newer replacement plasticizers.
In classrooms, these chemicals can collect in air, dust, tables, chairs, beds, and other high-touch surfaces. Young kids get more hand-to-mouth contact than adults, so classroom dust and surfaces matter.
What the research says
A 2026 study in Environment International measured plasticizers in 30 kindergarten classrooms. The study found DEHP at the highest levels in particles, dust, tables, and chairs. It also found an emerging plasticizer, 2,2,4-trimethyl-1,3-pentanediol diisobutyrate, at the highest level in the gas phase.
The same study identified flooring and beds as major source materials, with walls and curtains also contributing. It also found that surface-to-hand-to-mouth contact can be an important exposure path for some plasticizers.
What to do at home
You may not control a daycare floor. You can still ask how often high-touch surfaces are wet-cleaned, whether rooms are ventilated, and what nap materials are used. For items you buy, choose washable cotton layers and fewer soft PVC plastic items when that works for your family.
