Phthalates (diesters of phthalic acid) are used as plasticizers for several plastic materials, mainly PVC. They are among the organic substances that are present in the highest concentrations indoors, especially in house dust. Of the 6 phthalates (DMP, DEP, DnBP, DiBP, HIP, and DEHP) measured in this study, only DMP and DnBP showed a correlation between concentrations in house dust and indoor air. DnBP, DiBP, BBP, and DEHP serve nearly exclusively as plasticizers, these phthalates were considered to explain high concentrations in house dust with building characteristics. The building characteristics such as PVC floorings, plastic coated wall papers, plastic ceilings and wall coverings, plastic furniture, and plastic (covered) doors and windows were supposed to be possible sources for phthalates. There was a significant association between BBP concentrations in house dust and the relative floor area covered with PVC, an association much weaker for DEHR All the other building characteristics were not associated to any of the phthalates in house dust.
