“…The overall mean concentrations of total carbonyls at Nan-Chie (55.60 μg/m 3 ) were approximately 22.8% lower than at Hsiung-Kong (68.25 μg/m 3 ), consistent with the fact that the mean traffic volume (including motorcycles, gasoline cars, and diesel trucks) at Hsiung-Kong (11,067 vehicles per day) is about 60% higher than that at Nan-Chie (6,611 vehicles per day) (Lai et al, 2005). Table 3 presents the ratios of formaldehyde/ acetaldehyde (C 1 /C 2 ) and acetaldehyde/propionaldehyde (C 2 /C 3 ) thus obtained in this study and those obtained in other (Zhang et al, 1994;Possanzini et al, 1996;Slemr and Junkermann, 1996;Andreini et al, 2000;Grosjean et al, 2002;Ho et al, 2002b;Bakeas et al, 2003;Villanueva-Fierro et al, 2004;Moussa et al, 2006;Rubio et al, 2006;Pal et al, 2008). C 1 /C 2 ratios usually vary from one to two in an urban area to about ten in a rural area (Shepson et al, 1991;Possanzini et al, 1996).…”

The concentrations of 18 atmospheric carbonyls species were measured at Nan-Chie and Hsiung-Kong sites in Kaohsiung City, Taiwan, during the summer and winter of 2006. Formaldehyde and acetaldehyde were the most abundant carbonyls with respective annual mean concentrations of 17.99 μg/m 3 and 13.69 μg/m 3 at Nan-Chie, and 21.47 μg/m 3 and 16.68 μg/m 3 at Hsiung-Kong; altogether the two species accounted for approximately 56-57% of total carbonyls. In summer, the total concentrations of carbonyls were 74.06 μg/m 3 and 89.99 μg/m 3 at Nan-Chie and Hsiung-Kong, respectively. In winter, the concentrations were 37.14 μg/m 3 and 46.50 μg/m 3 at Nan-Chie and Hsiung-Kong, respectively. Measured results indicated the predominance of photolysis and photooxidation reactions of aldehydes in summer. In this study, receptor models using principal component analysis (PCA) and absolute principal component scores (APCS) suggest that the primary pollution sources at Nan-Chie in the summer were secondary emissions/vehicle exhausts (gasoline engines)/stationary emissions (food industry), stationary emissions (petrochemical)/waste treatment and restaurant emissions; the primary pollution sources at Nan-Chie in winter were vehicle exhausts (gasoline engines)/stationary emissions (petrochemical) and restaurant emissions. At Hsiung-Kong, the primary pollution sources in summer were secondary emissions/vehicle exhausts (gasoline engines and diesel engines)/stationary emissions (metal assembly), restaurant emissions and others; the primary pollution sources in winter were vehicle exhausts (gasoline engines)/restaurant emissions and vehicle exhausts (diesel engines)/stationary emissions (metal assembly).

“…In course of January sampling campaign minor differences occurs in concentration of aldehydes regardless of sampling points. Obtained results were similar to result of air quality monitoring of Milan surroundings obtained by Andreini et al [7]. Andreini et al indicated that during winter total concentration of aldehydes varies from 16.7 to 30.7 µg/m 3 at the urban locations and 11.7 µg/m 3 at the rural-industrial location.…”

Abstract. This study was carried out to characterize three aldehydes of health concern (formaldehyde, acetaldehyde, and acrolein) at a three sites in Silesian region (Poland) in January and June 2015. Aldehydes in polluted atmospheres comes from both primary and secondary sources, which limits the control strategies for these reactive compounds. Average aldehyde concentration in summer period lies in range from 3.13 µg/m 3 to 10.43 µg/m 3 , in winter period in range from 29.0 µg/m 3 to 32.2 µg/m 3 . Acetaldehyde was dominant compound in winter period, in summer formaldehyde concentration was highest of all determined aldehydes.

“…Atmospheric carbonyl compounds (CCs) are oxygenated volatile organic compounds, receiving worldwide attention (Andreini et al, 2000;Bakeas et al, 2003;Cavalcante et al, 2006;Pal et al, 2008;Uchiyama et al, 2012;Ho et al, 2013) since the last few decades. They are ubiquitous and are responsible for the degradation of poor air quality through the formation of tropospheric ozone and peroxy acetyle nitrate which in turn forms photochemical smog.…”

A study was conducted on atmospheric carbonyl compounds for the first time over a Himalayan atmosphere in India. Samples were collected from a high altitude hill station, Darjeeling (27.01°N, 88.15°E, 2200 masl) during June 2012 to May 2013. Temporal variation, meteorological influence, source apportionment and ozone formation potential etc were studied for acetaldehyde, formaldehyde, acetone, butanaldehyde, propanaldehyde, benzaldehyde, crotonaldehyde, valeraldehyde, isovaleraldehyde, hexanaldehyde, p-tolualdehyde and o-tolualdehyde. High concentration of Acetone (81.6 ± 63.5 µg m -3 ) was observed which could be due to the higher photochemical production from its precursor volatile organic compounds emitted from tea plants and tea processing units. The concentration of acetaldehyde (20.7 ± 47.6 µg m ). Meteorological parameters like temperature and surface reaching solar radiative flux played the major roles for the seasonal variation of the carbonyl concentration over the hill station. The average ratio of formaldehyde to acetaldehyde over Darjeeling was found to be 1.64 ± 1.43 well representing a typical urban atmosphere at this part of Himalaya. Positive matrix factorization model showed that the biogenic emissions from tea plants and vehicular emissions were the major sources of carbonyl compounds over the hill station.
