LOS ANGELES (CBS) — The Center of Health, Environment & Justice is out with a report Sunday suggesting that many back-to-school supplies might contain toxic chemicals.

They released a report that said 75% of supplies they tested in a laboratory had dangerously-high levels of toxic phthalates.

CHJ found the chemical in school supplies bearing the popular characters Dora, Spiderman and Disney favorites, among other.

The chemical, already banned in toys,  was found in many vinyl products including  book binders, backpacks, lunch boxes, 3-ring binders, raincoats and rain boots.

The American Chemistry Council says there is no evidence the chemical has harmed any humans in fifty years. But the CHJ says Phthalates have been linked to asthma, ADHD and birth defects.

Senator Charles Schumer (D-NY) wants to extend the ban on Phthalates to include school supplies.
