PUEBLO, Colo. (AP) - Authorities are searching for the source of a contaminant that sent six people in southern Colorado to the hospital.
The Pueblo Chieftain reports health officials have been focusing on a substance found in a room divider at a document center. Health officials say the substance can cause headaches and vomiting, similar to the symptoms that the employees had. It can be found in document equipment such as toner cartridges.
Officials say other factors might have played a part as well. Over 20 people were working in a small, windowless room and have reported frequent infections.
Health officials say the building is being cleaned and the air-exchange system tested.
Other samples taken from the building showed traces of ammonia, pesticides and jet fuel emissions.
