WEST HARTFORD, Conn. -- A new survey has found that one in three popular toys on sale right now have significant amounts of toxic chemicals in them.

At a testing event Tuesday, mom Elizabeth O’Neil said she couldn't believe what her 9-month-old daughter had been playing with last week.

“On Thanksgiving we were at my parents’ house,” she said. “She had them all in her mouth.”

She said she was furious and concerned about the findings.

The survey tested 1,500 popular toys and found 20 percent had lead in them and others had substances like mercury and arsenic.

“The testing is actually simple, straightforward, a 30-second test,” said Chris Corcoran, who tested a tea set, with which children might drink or eat. “Chemicals like mercury, arsenic, lead -- a potpourri of bad chemical things.”

The organization that tested the chemicals found that children’s jewelry tends to be the most contaminated. It said the toxic toys came from a variety of sources, not just china, for example.

The good news, however, is that lead levels overall have decreased since last year, the survey shows, and 20 percent of the toys had no chemicals at all.

Several state legislators at the testing in West Hartford said they would take the issue up at their next session.
