Kashyap, Durba; Agarwal, Tripti Concentration and factors affecting the distribution of phthalates in the air and dust: A global scenario Journal Article In: Science of The Total Environment, vol. 635, pp. 817 - 827, 2018, ISSN: 0048-9697. Abstract | Links | BibTeX | Tags: DBP, DEHP, Indoor pollution, Plasticizer, PVC @article{KASHYAP2018817,Phthalates are ubiquitously present environmental contaminants. Air and dust are the most important mediums of exposure to phthalates. The present study reviews the presence of phthalates in the air and dust reported from different countries in the last ten years (2007–2017). The phthalate concentrations revealed wide heterogeneity with a mean and median value 6 ± 19 μg/m3 and 0.5 μg/m3 respectively in the air and 1.5 × 103 ± 2.2 × 103 μg/g and 7.8x102μg/g respectively in the dust. The highest phthalates levels in the air were reported from India (1.1 × 102 μg/m3) and in dust from Bulgaria (1.2 × 104 μg/g). Overall higher levels were reported from developing countries as compared to developed countries. Di (2-ethylhexyl) phthalate (DEHP) and Di-n-butyl phthalate (DBP) were found to be predominant in both air and dust. Temperature, humidity, air exchange rate, building material and indoor maintenance were reported as the important factors influencing the levels of phthalates in the air and dust. In addition to policy level interventions, reducing the use of phthalate containing materials and controlling the factors which enhance the emission from existing sources can help in reducing human exposure to phthalates. |

Clausen, Per Axel; Xu, Ying; Kofoed-Sørensen, Vivi; Little, John C; Wolkoff, Peder The influence of humidity on the emission of di-(2-ethylhexyl) phthalate (DEHP) from vinyl flooring in the emission cell “FLEC” Journal Article In: Atmospheric Environment, vol. 41, no. 15, pp. 3217 - 3224, 2007, ISSN: 1352-2310, (Indoor Air 2005 - 10th International Conference on Indoor Air Quality and Climate (Part I)). Abstract | Links | BibTeX | Tags: DEHP, Emission, Humidity, Plasticizer, Vinyl flooring @article{CLAUSEN20073217,Asthma in children appears to be associated with both phthalate esters and dampness in buildings. An important question is whether the concentrations of phthalate esters correlate with dampness (expressed as relative humidity—RH) in indoor air. The objective was to study the influence of RH on the specific emission rate (SER) of di-(2-ethylhexyl)phthalate (DEHP) from one type of vinyl flooring in the well characterized Field and Laboratory Emission Cell (FLEC). The vinyl flooring with ca. 17% (w/w) DEHP as plasticizer was tested in 6 FLECs at 22°C. The RH in the 6 FLECs was 10%, 30%, 50% (in triplicate) and 70%. The RH was changed after 248d in 2 of the 50%-FLECs to 10% and 70%, and to 50% in the 10%-and 70%-FLECs. The data show that the SER of DEHP from vinyl flooring in FLECs during a 1yr period is independent of the RH. A new physically based emission model for semivolatile organic compounds was found to be consistent with the experimental data and independent of the RH. The model helps to explain the RH results, because it appears that RH does not significantly influence any of the identified controlling mechanisms. |
