Question from Judy
More on styrofoam please. I have orchids on windowsills that are terrazzo and very cold in the winter. I’ve put styrofoam boards from a craft store on top for their protection. Should I be worrying about this particular application?
Lisa’s Answer
The more significant health concern about styrofoam is that it can leach styrene, a probable carcinogen, into food and beverages when it is used as a container. There is probably not a significant exposure from this application.
I try avoid styrofoam, in general, because it is particularly bad for the environment due to a chemically-intensive manufacturing process and its inability to break down when it is disposed.
