Atmospheric concentrations and gas-particle partitions of pesticides: Comparisons between measured and gas-particle partitioning models from source and receptor sites

Occurrence, seasonal variation and inhalation exposure of atmospheric organophosphate and pyrethroid pesticides in an urban community in South China

“…The target CUPs were separated into three groups according to their gas-particle partitioning tendency. Chlorpyrifos (group 1) was the most often detected in the gas phase in all seasons with an average of 92% associated with the gas phase and this finding was similar to previous observations in Canada (Sadiki and Poissant, 2008). Group 2 contained dimefluthrin, allethrin and tetramethrin, which were almost equally distributed between the two phases, with 48%, 44% and 58% of the pesticides in the particle phase, respectively.…”

Gas/particle partitioning of currently used pesticides in the atmosphere of Strasbourg (France)

“…No correlation with temperature was observed for the partitioning process of trifluralin. G/P partitioning G/P partitioning was studied using the partitioning coefficient K P [m 3 /ng] (Yamasaki et al 1982;Bidleman 1988;Pankow 1991;Falconer and Bidleman 1994;Jenkins et al 1996;Chen and Preston 1997;Sanusi et al 1999;Chandramouli et al 2003;Tasdemir et al 2004;Callén et al 2008;Li et al 2008;Sadiki and Poissant 2008;Sauret et al 2008):…”

“…Great efforts were made by many research groups to understand the partitioning mechanisms and to predict the G/P partitioning of the pesticides (e.g. Junge 1977;Pankow 1987;Sofuoglu et al 2001Sofuoglu et al , 2004Sadiki and Poissant 2008), but most of these studies were carried out on compounds like DDT or HCB that have been prohibited in the industrialised countries because of their long persistence in the atmosphere. These pesticides have been replaced with a new and much vaster generation of pesticides for that very little information is available as only a few studies on its G/P partitioning were carried out so far, and only on a small part of the pesticides from this new generation (Callén et al 2008;Sadiki and Poissant 2008;Sauret et al 2008;Scheyer et al 2008).…”

Development of a gas chromatography–mass spectrometry method for the determination of pesticides in gaseous and particulate phases in the atmosphere

“…Moreover, standardized analytical methods have also been established for occupational exposure monitoring, e.g., the determination of organonitrogen pesticides in air [14]. With respect to the atmosphere, several studies have reported atmospheric concentrations of pesticides after their application in open or confined areas [6,[15][16][17][18] and individual values or temporal series in different locations -agricultural, urban and rural areas - [10,[19][20][21][22][23][24][25][26][27][28].…”
