摘 要：On April 15, 2011, NIOSH received an employee request regarding headaches, fatigue, weakness, fever, chills, flu-like symptoms, shortness of breath, coughing, chronic sinusitis, sore throat, burning eyes, and difficulty concentrating in a water-damaged building. In June 2011, NIOSH investigators conducted a site visit. The majority of employees reported building-related symptoms. We found evidence of water damage inside the building and mold inside supply air ducts of two air handlers. Vacuumed carpet dust samples collected during the site visit showed a high burden of culturable fungi and bacteria. We provided a number of recommendations for remediation including addressing causes of water damage and replacing contaminated carpet and ductwork. Building management replaced two rooftop air handling units and some ductwork. The carpet was steam cleaned. Some building occupants continued to have symptoms, and the accounting company relocated to another building.
