Volatilisation of crop protection chemicals from crop and soil surfaces under controlled conditions—prediction of volatile losses from physico-chemical properties

Volatilisation of pesticides under field conditions: inverse modelling and pesticide fate models

“…The increased volatilisation for components with a vapour pressure higher than 10 −5 Pa is in agreement with general rules of thumb in the literature. 7 In this study, the emission rate of chlorothalonil immediately after application was 143.4 g m h −1 . 56 Furthermore, the simulated emission rate is higher than the calculated rate, which is also observed in the present study.…”

The Glasgow consensus on the delineation between pesticide emission inventory and impact assessment for LCA

“…to agricultural soil in USEtox-CFs for all other emission media are representing off-field emission media and are thus not applicable). In the absence of widely applicable pesticide emission models at the time, this was considered an approximate solution for (Bilanin et al 1989;Ganzelmeier et al 1995;Holterman et al 1997;Bird et al 2002;Teske et al 2002;Siebers et al 2003;Gil and Sinfort 2005;Gil et al 2007;Gil et al 2008;Wang and Rautmann 2008;Teske et al 2009;Butler-Ellis et al 2010;Lebeau et al 2011) Volatilisation (Kubiak et al 1995;Rüdel 1997;Bedos et al 2002a;Scholtz et al 2002;Bedos et al 2002b;Wolters et al 2003;Guth et al 2004;Leistra et al 2005; Runoff (Huber et al 1998;Sexton et al 2000;Kellogg et al 2002;Inao et al 2003;Miao et al 2003;Liu et al 2004;Berenzen et al 2005;Numabe and Nagahora 2006;Schriever et al 2007;Phong et al 2011;Thuyet et al 2012) Washoff (Smith and Carsel 1984;Cohen and Steinmetz 1986;Willis et al 1994;Fisher et al 2002) Plant uptake (Trapp and McFarlane 1995;Fryer and Collins 2003;…”

Relationship Between the Evaporation Rate and Vapor Pressure of Moderately and Highly Volatile Chemicals

“…Numerous researchers, however, have suggested that volatile losses from soil, crops, and aqueous systems can be estimated from physico-chemical parameters (Hamaker 1972;Burkhard and Guth 1981;Smit et al 1998). Guth et al (2004) reported the results of more than 190 experiments, which were carried out with 80 different crop protection chemicals under controlled conditions (laboratory and/or greenhouse). Their data analysis showed that physico-chemical parameters, such as vapor pressure (VP), Henry's law constant, water/air and soil/air distribution coefficients can be used to make reasonable predictions of volatile losses from crop and soil surfaces, and that VP was the best predictor of losses from soil and crops.…”
