This article studied the exposure to 45 defined volatil organic compounds in an university art school, ventilated with a 100% exhaust mechanical ventilation system. Several students wore passive dosimeters.Floors where no emission of VOCs occurred had no detectable exposures : the conclusions show that a non-recirculating ventilation system can eliminate indoor air quality issues between floors.
The effect on Indoor Air quality of painting at home has been debated. This paper presents a case study where a normal Scandinavian two-bedroom apartment has been refurnished with new paint on the walls and ceilings and the VOC emissions have been measured during eight weeks. Low-emitting wall and ceiling paint was selected for the study and a paint shop rolled two layers of new paint on the walls and ceilings in two rooms. Parallell the paints were applied to glass plates according to the Scandinavian trade standard and investigated with the FLEC method in the laboratory.
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.
Summarises the results of product analyses and a series of small chamber emissions tests on alkyd paint. Also describes the use of a mass balance approach to evaluate the impact of test variables and to assess the quality of the emissions data.
Application of industrial painting is often carried out by air-atomization. In this case, health hazards arise from the exposure to solid and liquid aerosols as well as to solvent vapors. Control of these airborne pollutants may be achieved through the use of a spray booth, whose effectiveness depends also on the number and dimension of the openings, on the main air flow rate, as well as on the direction and flow rate of secondary air streams.
This report reviews research into the release of volatile organic compounds (VOCs) from paints and coatings from two perspectives: (a) drying and film formation, and (b) voc emission into indoor air. The former has been investigated by the paint industry for some decades, especially in relation to understanding drying mechanisms to assist product formulation and development. The latter is of more recent interest and is directed to predicting and controlling the impact of VOC emissions from paints and coatings on indoor air quality.
