Describes a longitudinal study of 83 social workers in two office building in Sweden. The exposed group moved to a newly redecorated building nearby, using low emitting building materials and solvent-free paint. Findings indicated that the move resulted in an increase in the personal outdoor airflow rate. The move resulted in increased nasal patency and ECP and lysozyme in NAL. Concludes that no major ocular or nasal effects or measurable increase in indoor air pollution need to result from redecoration of a well-ventilated building, if low emitting materials are chosen.
