Possible copper or solvent intoxication to the four employees of the Bookkeepers Tax Service (SIC-7299), Lufkin, Texas was investigated. The study was requested by the owners after employees had experienced a variety of symptoms including mucous membrane irritation, dizziness, and gastrointestinal problems. On October 4, 1980 investigators measured exhaust air flow, obtained soil and dust samples, and collected medical information. There was no evidence for solvent exposure or for copper fume or unusual copper dust exposure. Air sampling for formaldehyde and carbon-monoxide indicated normal values. Airflow through the building relied upon recirculated air without fresh makeup. All urine and blood samples contained copper in the normal range. The authors conclude that the symptoms reported were not fully explained but that indoor air quality might be poor, especially for the warmest summer months. The authors recommend that the ventilation system be improved with fresh makeup air.
