Hartford (WTNH) - New safety tests have identified some toys you may want to avoid this holiday season.

The students at Trinity College are too old to play with toys, but they did test dozens of them to see if they contained lead or lead paint.

"Lead can interfere with many biological pathways and can do damage to many bodily systems," explained Brian Castelluccio, Trinity College student.

As it turns out, they found no toys with lead above acceptable levels in the 73 they tested, but Connecticut's Commissioner of Consumer Protection, Jerry Farrell Jr., says there has been an upswing in lead paint.

"No one ever thought that 30 years after lead paint was banned in the United States that we would see it again present and, unbelievably, in children's toys," Farrell said.

Commissioner Farrell also warns that other dangerous chemicals could be hiding in children's art supplies. The best way to tell they're safe is to look for the ASTM approval printed on the container. That proves that the art supplies have been tested and found safe - and that's crucial to know before you let your kids use those paints and markers.

"There are 179 items that we have pulled off of the shelves presently because they lack this language on them," Farrell said.
