NORTH ADAMS, Mass. -- "You hear the word 'mercury' and you kind of freak out about it, but we're just glad she was safe," said North Adams resident Jay Deeley.

Jay and his wife Kelly are relieved to know their daughter is safe after a Conte Middle School student intentionally spilled mercury earlier this week. But not everyone was as lucky. City officials say one girl has been treated for mercury exposure and her house has been condemned because of the contamination. That has some parents worried about their children's safety, even though doctors say there is not a significant health risk.

"The parents should know that the children that weren't directly exposed are safe," said North Adams Regional Emergency Department Medical Director Paul Donovan.

Dr. Donovan says if a child did come in direct contact with the toxic material, there could be symptoms.

"They may feel a warm touch to the skin. They may actually get a slight pinkish or red rash around the area they touched, so most of the potential symptoms by direct contact would be skin related," said Dr. Donovan.

As some parents continue to worry about their children's health, the father of one Conte Middle School eighth grader says students heard about plans to spill the mercury days before it happened.

"I guess most of the students knew about it before any of the teachers. I don't think they knew exactly what mercury was or anything like that," said Deeley.

"As a parent, it was scary because the school was not able to notify us that our children were being released early. So it freaked us out when she got off the bus at noontime and said her school got evacuated for mercury," said Kelly Deeley.

Police still have not released the name of the child who spilled the toxic material, but they say serious criminal charges are pending. And because the girl who was treated for exposure is also a minor, her name and the address of her condemned house in North Adams also has been released.
