Emission characteristics of biogenic volatile organic compounds from representative plant species of the korean peninsula focused on Aldehydes
Atmospheric Research, 2020Co-Authors: Soyoung Kim, Jochun Kim, Chanryul Park, Younsuk SonAbstract:Abstract This study was performed to estimate the Aldehyde (formAldehyde, acetAldehyde, propionAldehyde, etc.) Emission rates regarding the various plant species (Pinus densiflora, Pinus koraiensis, Quercus acutissima, Quercus variabilis, Ginkgo biloba and Oryza sativa) of the Korean peninsula. Accordingly, the average Aldehyde-Emission rate of the deciduous trees is 1073 ng gdw−1 h−1, and this is higher than that of the coniferous trees (497 ng gdw−1 h−1). The summer Aldehyde-Emission rate of P. koraiensis (608 ng gdw−1 h−1) is the highest among all the target coniferous trees; for the deciduous trees, the Aldehyde Emission of Q. variabilis of 1197 ng gdw−1 h−1 is the highest. Additionally, the acetAldehyde amount accounted for 30–60% of the total Aldehydes emitted in summer from all the coniferous trees except P. koraiensis in summer. For the deciduous trees in fall, propionAldehyde represents >40% of the total Aldehyde Emissions of all the target trees except for Q. variabilis (acetAldehyde: 81%). Regarding the Aldehyde Emissions of Ginkgo biloba and Oryza sativa, however, we could not identify significant environmental-factor relations. When we compared the measured and modeled values using the T80 (only temperature) and G93 (temperature and PAR) models, the Aldehyde Emissions of P. densiflora show similar correlations in both models; however, for Q. variabilis, the correlation coefficient of G93 model is higher than that of the T80. In case of propionAldehyde, it is difficult to predict the Emission rate using both the T80 and G93 models.

surface Emission determination of volatile organic compounds voc from a closed industrial waste landfill using a self designed static flux chamber
Science of The Total Environment, 2014Co-Authors: Eva Gallego, J F Perales, F J Roca, X GuardinoAbstract:Abstract Closed landfills can be a source of VOC and odorous nuisances to their atmospheric surroundings. A self-designed cylindrical air flux chamber was used to measure VOC surface Emissions in a closed industrial landfill located in Cerdanyola del Valles, Catalonia, Spain. The two main objectives of the study were the evaluation of the performance of the chamber setup in typical measurement conditions and the determination of the Emission rates of 60 different VOC from that industrial landfill, generating a valuable database that can be useful in future studies related to industrial landfill management. Triplicate samples were taken in five selected sampling points. VOC were sampled dynamically using multi-sorbent bed tubes (Carbotrap, Carbopack X, Carboxen 569) connected to SKC AirCheck 2000 pumps. The analysis was performed by automatic thermal desorption coupled with a capillary gas chromatograph/mass spectrometry detector. The Emission rates of sixty VOC were calculated for each sampling point in an effort to characterize surface Emissions. To calculate average, minimum and maximum Emission values for each VOC, the results were analyzed by three different methods: Global , Kriging and Tributary area . Global and Tributary area methodologies presented similar values, with total VOC Emissions of 237 ± 48 and 222 ± 46 g day − 1 , respectively; however, Kriging values were lower, 77 ± 17 g day − 1 . The main contributors to the total Emission rate were Aldehydes (nonanal and decanal), acetic acid, ketones (acetone), aromatic hydrocarbons and alcohols. Most aromatic hydrocarbon (except benzene, naphthalene and methylnaphthalenes) and Aldehyde Emission rates exhibited strong correlations with the rest of VOC of their family, indicating a possible common source of these compounds. B:T ratio obtained from the Emission rates of the studied landfill suggested that the factors that regulate aromatic hydrocarbon distributions in the landfill Emissions are different from the ones from urban areas. Environmental conditions (atmospheric pressure, temperature and relative humidity) did not alter the pollutant Emission fluxes.
