Polymeric building materials and equipment for indoor use in spaces intended for people may, in an essential way, contribute to the deterioration of wholesome quality of life. Phthalates, present in many products, constitute an omnipresent group of compounds used widely as plasticisers. The research results show that these substances may negatively impact human health, and thus European Union has implemented several regulatory measures restricting their use. Manufacturers and suppliers must comply with these regulations. As a result, it is necessary to investigate and determine the contents of phthalates in these materials. This paper presents the analytic profile of the method of marking phthalates extracted from polyvinyl chloride using HPLC chromatography with UV-VIS detection and selected results obtained in examinations of materials used in interior design. The results of described examinations of phthalates content indicate that not all materials recommended by manufacturers may be used indoors in spaces intended for people. The method was verified for its suitability for routine analyses of materials made of PVC and submitted for attestation. The elaborated method can be used to determine the banned phthalates’ presence in PVC. The method allows for detecting these phthalates at the level required by the REACH regulation, and its validation parameters are highly satisfactory considering a very complex matrix.
