Laboratory tests conducted in Zlín, southeast Moravia, have found that
five in nine Czech school products contain a high share of toxic substances
known as phthalates. Items tested at the request of the Czech environmental
NGO Arnika included pencil cases, exercise book jackets and erasers, which
present a risk if put under mechanical stress or chewed, like a marker
cover or eraser. The crux of the problem is that while Czech and EU laws
limit phthalates in toys or other products, they do not take into account
school products.
