Title

Phthalic esters in the indoor environment. Test chamber studies on PVC-coated wallcoverings

Abstract
Phthalic acid esters are important additives in polyvinyl chloride (PVC) products. Since PVC plastisoles for the production of wallcoverings contain about 30 % phthalic acid esters, it is a crucial question whether these products can contribute to the pollution of the indoor environment. In this study, the emission of several technically relevant phthalates from PVC-coated wallcoverings were measured in emission test chambers under standard room conditions. During a 14-day test period, both the chamber air concentrations and the condensation on a cooled plate (fogging) were determinded. In the chamber air, maximum concentrations of 5.1 µg/m³ for di-n-butylphthalate (DBP), 2.08µg/m³ for di-pentylphthalate (DPP) and 0.94 µg/m³ for di-(2-ethylhexyl)phthalate (DEHP) were found. After 14 days of exposure, up to 60.4 µg DEHP and 17.7 µg DPP could be quantified on the cooled plates of the fogging apparatus. The amounts of DBP and DIBP were significantly lower. A simple exposure calculation indicated no specific risk of an increased phthalate exposure in rooms with PVC wallcoverings.
