At the request of wallcoating manufacturers, tests on eight different products were carried out in small environmental test chambers at 0.5/hr air exchange rate. Formaldehyde concentrations were found to be relatively high for a few hours after introduction, but decayed to below 0.05 mg/m3 after 1 to 7 days. Butanone showed a similar pattern. Vinyl chloride was always below detection limits. TVOC presented concentrations of a few mg/m3 (two products 49 and 98 mg/m3) initially, but for all products except one they decreased to less than 0.4 mg/m3 after one week. Plasticiser concentrations were slightly in excess of the blank values. Overall, the products tested appear safe, except for the persisting high TVOC from one product; a good ventilation of the rooms for few days after installation is recommended.
