| Popis: | Phthalates are ubiquitous indoor organic pollutants that are found in different building and consumer materials and are known to cause severe human health problems. In this paper, the emission of these compounds from vinyl floorings (VF) into indoor air has been studied using Automated Thermal Desorption-Gas Chromatography-Mass Spectroscopy (ATD-GC-MS) and a special device known as micro-chamber or thermal extractor (μ-CTE™). So a robust analytical ATD-GC-MS method has been developed and validated to analyse eight selected phthalates. Calibration curves were linear (R2 > 0.99), limit of detection (LOD) was down to 0.004 μg/m3, and the values of relative standard deviation (RSD) were less than 15% for all chosen phthalates. Then, a new micro-chamber measurement method based on diffusion has been developed for studying the emission of Diisononyl phthalate (DiNP) and Di-n-octyl phthalate (DnOP) from VF at different temperatures and estimating y0 (gas-phase concentration of phthalates on the surface of the material). This method was quite repeatable with 11% RSD for DiNP and 8% for DnOP. |
