ISO 16000 specifies the sampling and analysis of phthalates in indoor air and describes informatively the sampling and analysis of phthalates in house dust and in solvent wipe samples by means of gas chromatography/mass spectrometry. Two alternative sampling and processing methods, whose comparability has been proven in an internal round robin test, are specified for indoor air. Sampling can take place by adsorption on thermal desorption tubes that are, e.g. filled with Tenax® TA1)) or quartz wool or deactivated glass wool and are subsequently processed by means of thermal desorption. Alternatively, sampling can take place by adsorption on adsorbents, e.g. Florisil®2)) that are subsequently processed by means of solvent extraction. The procedure for the measurement of dimethyl phthalate up to di-n-octyl phthalate in indoor air is designed for a sampling duration of 2 h to 24 h, depending on the sampling and processing method. In due consideration of the method blank values, typical concentrations of 100 ng/m3 and 10 ng/m3 for di(2-ethylhexyl) phthalate and dimethyl phthalate, respectively, can be measured by this analytical procedure. Depending on the sampling method, the compounds dimethyl phthalate to diisoundecyl phthalate can be analysed in house dust as informatively described in Annex C. The investigation of house dust samples is only appropriate as a screening method. This investigation only results in indicative values and is not acceptable for a final assessment of a potential need for action. Dimethyl phthalate to diisoundecyl phthalate can be analysed in solvent wipe samples as informatively described in Annex B. Solvent wipe samples are suitable for non-quantitative source identification.
