“…Formaldehyde samplers, both active and passive, were based on the 2,4-dinitrophenylhydrazine (DNPH) methodology (Szulejko and Kim, 2015). For passive formaldehyde samples, Radiello chemiadsorbing cartridge code 165 tubes (Fondazione Salvatore Maugeri, Pavia, Italy) and UME x 100 passive samplers were obtained from Supelco (Bellefonte, PA, USA) and SKC (Eighty Four, PA, USA), respectively.…”

Emission factors of formaldehyde and VOCs were determined for two waste treatment plants (WTP) located in\ud the metropolitan area of Barcelona city. Formaldehyde emission factors were determined from the biogas engines\ud exhausts and the process chimneys (after the biofilter process), and VOC emission factors were determined\ud in the process chimneys. Formaldehyde and VOC were dynamically sampled usingDNPH-coated adsorbent tubes\ud with ozone scrubber and multi-sorbent bed tubes (Carbotrap, Carbopack X and Carboxen 569), respectively,\ud using portable pump equipment. Formaldehyde emission factors from biogas engines were found between\ud 0.001–0.04 g s-1. Additionally, formaldehyde and VOC emission factors from process chimneys were found to\ud be between 0.0002–0.003 g s-1 and 0.9 ± 0.3 g s-1, respectively. Employing real emission factors, the expected\ud concentrations derived from the WTPs in their nearby urban areaswere calculated using The Atmospheric Pollution\ud Model (TAPM, CSIRO), and impact maps were generated. On the other hand, ambient air formaldehyde and VOC\ud concentrations were determined in selected locations close to the evaluated waste treatment facilities using both\ud active and passive samplers, and were between 2.5±0.4–5.9±1.0 µgm-3and91±48–242±121 µgm-3, respectively.\ud The concentrations of formaldehyde and VOC derived exclusively from the waste treatment plants were\ud around 2% and 0.3 ± 0.9% of the total formaldehyde and VOC concentrations found in ambient air, respectively.Postprint (author's final draft

The E/Z isomerization of asymmetric hydrazones both in solution phase and on-column in GCs has been reported (Engewald and Dettmer-Wilde, 2014;Ho and Yu, 2004;Li et al, 2009;Trapp et al, 2003) and reviewed (Szulejko and Kim, 2015;Vogel et al, 2000).…”

“…Most commonly used method for the collection of airborne CC is to use an adsorbing material with a derivatization agent to capture CC, followed by solvent (Soman et al, 2008) or thermal desorption (Ho, et al, 2004) and analysis using a chromatographic or spectroscopic methods (Szulejko, et al, 2015). Various derivatization materials are reported by many research groups (Szulejko et al, 2015).…”

“…Various derivatization materials are reported by many research groups (Szulejko et al, 2015). However 2,4-di-nitrophenyl hydrazine (2,4-DNPH) is the most commonly used derivatization agent (Szulejko et al, 2015). Even though there are few drawbacks (Pal et al, 2007), the 2,4-DNPH derivatization-based HPLC method can be considered as a cheaper and easier methods for the determination of CC.…”

Development of a paper-based approach for the detection of carbonyl compounds in indoor air samples

This study contributes to the development of a method to measure the level of airborne carbonyl compounds. Carbonyl compounds (CC) are very common indoor air pollutants which are widely used in building and home furnishing industries. Most CC off-gas or vaporize even at normal room temperatures, which results in an increase in the indoor volatile organic carbon levels. Acute and chronic exposure to formaldehyde can result in respiratory symptoms and eye, nose, and throat irritation in humans. Because of these adverse health effects and the increased levels of CC in indoor air and residential areas, there has been a considerable attention toward the development of sensitive methods to monitor indoor CC levels. Most methods available for monitoring indoor CC levels are indirect and time consuming. This paper describes a novel, portable, on site, low-cost and green method for regular monitoring of CC in air. In this method, the derivatization reagent, 2,4-dinitrophenylhydrazine (2,4-DNPH) was used to capture the airborne Cc. Formaldehyde was used as the CC for this study. A novel paper-based platform soaked with 2,4 DNPH was used for the quantification of air born cc. Derivatives of CC were formed on a paper-based platform which were then directly analyzed using FTIR or an image scanner. The FTIR response for the carbonyl derivatives, which correlates with the levels of airborne CC, was used to quantify the levels of airborne cc. The same was scanned using a high resolution image scanner to obtain the RGB values and the yellow color intensity was calculated. Based on the RGB values, the produced yellow color intensity and the levels of CC produced a linear relationship. The use of an image scanner to quantify the levels of CC makes this method a portable, sensitive and on-site CC detection method. This newly developed paperbased FTIR method is agreeable with the stranded HPLC method at 95% confidence limit.
