MADISON, Wis. -- A Darlington-area family is heading to the state Capitol on Tuesday with hopes of improving the air quality in Wisconsin schools.

Their campaign was spurred by the life-threatening experience that their daughter went through because of the air that she was breathing in the classroom.

This is an issue where many children can function just normally in the classroom environments they're in, but for some, high levels of mold, carbon dioxide, poor ventilation and other air quality issues can create serious health concerns.

Dick and Jeanne Black and their daughter Jade will head to the Capitol as legislators prepare to vote a piece of legislation that they support, Senate bill 325. Under the bill, an indoor air quality task force would oversee new school construction while helping remediate existing building problems, WISC-TV reported.

"I'm excited and nervous at the same time," Dick Black said.

"We hope it will make a big difference in the health and the safety for our students," Jeanne Black said.

Their crusade began when Jade kept getting sick while attending classes inside the 9-year-old Darlington Elementary and Middle School.

"(Jade) was diagnosed with severe mold induced asthma," Jeanne Black said.

The Blacks said that the illness produced severe symptoms in their daughter.

"She also had headaches, migraines, blurred vision, rashes on her face, stomach aches, nausea," they said.

Dick Black said that they couldn't identify what it was causing her symptoms, but they finally learned it was "sick building syndrome." Under doctor's orders, Jade transferred to Belmont and her health has returned and she is an honors student.

"She's our healthy daughter back again," Jeanne Black said.

While their daughter is now OK, the Blacks' concern is now for other susceptible Wisconsin children who they believe are also getting sick from tightly-sealed, newer schools, WISC reported.

"We couldn't get any help locally," Dick Black said. "We just kept hitting, running in to walls, and finally decided something has to be done, 'And let's take this on.'"

The Blacks have hung a handmade plaque in their dining room to the successful effort thus far.

"You don't need people in numbers," Jeanne Black said. "If you approach it in a diplomatic way, you can try to make a difference, and you can show your children how you can make a difference."

The superintendent of Darlington schools said that air testing has been done and no serious issues have been identified.

However, a Wisconsin Education Association Council survey has identified at least 80 state schools with air quality problems, WISC-TV reported.
