High levels of carbon dioxide and traces of mold have been found in four portable classrooms at a Kanawha County elementary school.
The Charleston Daily Mail reports that the school system conducted initial tests at Andrews Heights Elementary School after teachers reported students with sinus and ear infections, chest congestion, headaches, and lethargy.
Pinnacle Environmental Consultants was hired to do further testing. The firm says air quality samples it took April 14 showed carbon dioxide levels in one classroom at 2,125 parts per million. Another classroom registered at 1,850 parts per million. A day earlier, air samples registered at 1,169 parts per million.
Industry standards for carbon dioxide are less than 1,000 parts per million.
