“…Contamination from the ambient air of the laboratory can be significant. Concentrations of DnBP, DiBP and DEHP in laboratory air have been reported between 0.37 and 3.0 µg/m 3 (Baram et al, 2000;Fankhauser-Noti et al, 2007), which can cause contamination of glassware and solvents. To avoid overestimating PAE concentrations during sampling and the experiment, it is recommended to avoid the personal use of hand creams, perfumes, deodorants, and any cosmetic products that contain PAEs (Félix-Cañedo et al, 2013).…”

“…All laboratory glassware should be washed with an appropriate organic solvent such as cyclohexane, n-hexane, isooctane, methanol or 2,2,4trimethylpentane (Hashizume et al, 2002;Tienpont et al, 2004). An acidic solution such as hydrochloric acid, sulfochromic mixture or mixture of ammonium persulfate and sulfuric acid (Cincinelli et al, 2001;Dargnat et al, 2009;Mousa et al, 2013) or a 1 M potassium hydroxide solution (Baram et al, 2000) can also be used.…”

Because of their widespread application, phthalates or phthalic acid esters (PAEs) are ubiquitous in the environment. Their presence has attracted considerable attention due to their potential impacts on ecosystem functioning and on public health, so their quantification has become a necessity. Various extraction procedures as well as gas/liquid chromatography and mass spectrometry detection techniques are found as suitable for reliable detection of such compounds. However, PAEs are ubiquitous in the laboratory environment including ambient air, reagents, sampling equipment, and various analytical devices, that induces difficult analysis of real samples with a low PAE background. Therefore, accurate PAE analysis in environmental matrices is a challenging task. This paper reviews the extensive literature data on the techniques for PAE quantification in natural media. Sampling, sample extraction/pretreatment and detection for quantifying PAEs in different environmental matrices (air, water, sludge, sediment and soil) have been reviewed and compared. The concept of "green analytical chemistry" for PAE determination is also discussed. Moreover useful information about the material preparation and the procedures of quality control and quality assurance are presented to overcome the problem of sample contamination and these encountered due to matrix effects in order to avoid overestimating PAE concentrations in the environment.

“…10/2011 as of 14 January 2011 does not authorize the use of phthalates for manufacturing food-contact materials, phthalates have been detected in PET material and in PET-bottled water. There are several possibilities for the occurrence of phthalates in bottled water such as: (i) quality of the raw material as well as the technology used in bottle production (Amiridou and Voutsa, 2011;Schmid et al, 2008) or perhaps chemicals used in the production process (Plotan et al, 2012, Wu et al, 2012); (ii) use of recycled PET (Bach et al, 2012); (iii) contamination of the water sources with decomposed plastic wastes of dumps (Baram et al, 2000); (iv) cross-contamination in the bottling factory as phthalates are ubiquitous in the environment (Biscardi et al, 2003;Higuchi et al, 2004;Leivadara et al, 2008;Liu et al, 2008); (v) cap sealing resins (Hirayama et al, 2001) may present contamination.…”

Carbonated and non-carbonated mineral water samples bottled in 0.5-L, 1.5-L and 2.0-L polyethylene terephthalate (PET) containers belonging to three different water brands commercialized in Hungary were studied in order to determine their phthalate content by gas chromatography -mass spectrometry. Among the six investigated phthalates, diisobutyl phthalate, di-n-butyl-phthalate, benzyl-butyl phthalate and di(2-ethyl-hexyl) phthalate (DEHP) were determined in non-carbonated samples as follows: 3

On-column preconcentration in sequential injection chromatography: application to determination of parabens

Solid-phase extraction is the most usual technique for analyte preconcentration prior to liquid chromatographic analysis. It involves several time-consuming steps, including cartridge conditioning, sample loading and analyte elution. This work proposes on-column preconcentration in sequential injection chromatography by exploiting analyte retention at the head of the chromatographic column. A relatively high volume of an aqueous sample was carried to the reversed-phase column by water. After preconcentration, a suitable mobile phase was inserted to perform chromatographic separation. The feasibility of the proposed approach was demonstrated by preconcentration of parabens before chromatographic separation and UV detection. A linear response was achieved from 12.0 to 100.0 ng mL À1 (r 2 > 0.998) with detection limits estimated to be 3.1, 3.3 and 4.6 ng mL À1 and enrichment factors of 435, 405 and 420 for methyl, ethyl, and propylparabens, respectively. Coefficients of variation for retention time and peak heights were below 2.2%. The proposed procedure can be applied to paraben extraction and preconcentration, presenting advantages such as minimization of analyte losses and contamination, reduction of organic solvent consumption and avoiding additional extraction cartridges.
