CARPENTERSVILLE, IL — Several students and staff at Golfview Elementary  School were hospitalized yesterday after complaining of headaches and nausea  caused by a strange odor, according to the St. Charles Sun.
Students were sent to the gymnasium while air quality tests were performed  throughout the school, the story stated.
Joe Stevens, president of the School Board in District 300, said: "It smells  like a lemony odor or like ant spray."
An odor was found in two classrooms and in the library, but air quality  tests found nothing noteworthy, the story noted.
Officials believe the symptoms were caused by fumes left in the building  from cleaning products used after contractors removed tile and asbestos from the  building during spring break, the story added.
According to the story, the school remains closed today so it can be  properly ventilated.
