“…The combustion of 5-10 cigarettes in a room of 30 m 3 increases the formaldehyde concentrations from 240 to 600 mg m À3 (ref. 33). However, formaldehyde levels measured in the bar were similar to those found in the teacher's office and in Research Laboratory 1 probably due to mechanical ventilation and the great surface of more than 300 m 3 of the bar.…”

Field evaluation of the Analyst® passive sampler for the determination of formaldehyde and acetaldehyde in indoor and outdoor ambient air

et al. 2013

The performance of the AnalystÒ passive sampler for the measurement of formaldehyde and acetaldehyde was assessed in a series of field experiments. It consists of a polyethylene cylinder filled with silica gel or a FlorisilÒ adsorbent and a stainless steel or a silver anti-turbulence net which works as an ozone scrubber. Indoor and outdoor formaldehyde and acetaldehyde concentrations were measured in different locations (offices and rooms of a public building, a car, laboratories and private homes) of Ciudad Real (Spain) and Rome (Italy). In some cases, RadielloÒ passive samplers were used along with AnalystÒ, in order to compare and validate the results. The performance of the AnalystÒ device was also assessed by checking some parameters such as the diffusive sampling rate of acetaldehyde and the storage stability after collection and the self-consistency for both formaldehyde and acetaldehyde. From this work, it can be concluded that the AnalystÒ sampler is suitable for measuring formaldehyde and acetaldehyde in indoor and outdoor air.

“…La méthodologie précédemment élaborée pour déterminer les compsoés carbonylés à l'intérieur des locaux [7,8] a été adaptée au dosage du formaldéhyde, de l'acétaldéhyde, de l'acétone , de l'acroléine et du benzaldéhyde dans les effluents automobiles. Elle comporte le passage de l'air à analyser au travers d'une cartouche de silice imprégnée de dinitro-2,4-phénylhydrazine (DNPH) et l'analyse des hydrazones ainsi formées par chromatographie liquide à haute performance.…”

“…3 Formaldehyde is also present in wood smoke 4 and tobacco smoke. 5 It was shown that formaldehyde (FA) exposure has an irritant effect on the eyes, nose and upper airways. Since 2004, it has been classified in group 1 (human carcinogen) by the International Agency for Research on Cancer based on sufficient evidence from epidemiological data.…”

A diffusive sampling device was developed for screening indoor sources of formaldehyde and determining the emission rates of these sources on-site. It consists of a glass Petri dish containing a quartz filter coated with 2,4-dinitrophenylhydrazine (DNPH) which is placed on the tested material for sampling. Formaldehyde emitted from the material diffuses through the air column inside the sampler and is collected onto the DNPH filter. The formaldehyde emission rate is determined from the mass collected by the sampler. The dependence of the sampled formaldehyde amount on the diffusion length inside the sampler was examined and led us to select a length of 20 mm for which the diffusion in the air layer controls the mass transfer from the material to the sampling surface (filter). A linear relationship with a high correlation (r 2 ¼ 0.97) was obtained between the mass collected by the passive flux sampler and the emission rates measured by a standard chamber method, analysing a large series of indoor materials with the two methods in parallel. Neither the sampling time (ranging from 4 to 8 h) nor the temperature (from 23 to 35 C) was observed to influence the sampler performance. Furthermore, the detection limit attained 1.2 mg m À2 h À1 for a 6h-sampling time and a satisfying precision of replicate measurements (relative standard deviation of 7.8% on average) is adequate for monitoring the emission rates of primary sources contributing to formaldehyde indoor concentrations.
