Table 1. Pesticide speciation profile from the 2000 California VOC emissions inventory.

in INVESTIGATION OF ATMOSPHERIC OZONE IMPACTS OF SELECTED PESTICIDES Final Report to the California Air Resources Board Contract No. 04-334 By
by William P. L. Carter, Irina L. Malkina 2007
"... In PAGE 16: ... The VOCs present in pesticides used in California, and the extent of our knowledge and ability to represent their atmospheric ozone impacts, are discussed in the following section. Volatile Organic Compounds in Pesticides Table1 shows the VOC speciation profile that is used to represent pesticide emissions in the 2000 California VOC emissions inventory. The approximate mass fractions, which represent the relative amounts of each compound that are estimated to be emitted, are also shown, with the compounds listed in order of decreasing amounts emitted.... In PAGE 16: ... Footnotes to the table indicate the meanings of the uncertainty classifications used. Note that if there is no SAPRC-99 model species indicated for a compound in Table1 , then there is presently no way to estimate the ozone impact of the compound, except by using highly lumped mechanisms whose applicability is subject to significant uncertainty. The first compound on the list is methyl bromide, which is currently represented using a placeholder mechanism that probably does not correctly represent its mechanistic reactivity.... In PAGE 16: ... Therefore, studies of the atmospheric ozone impact of this compound is not considered to be a priority for atmospheric ozone impact assessment. After methyl bromide the most important compound according to Table1 is methyl isothiocyanate (MITC). Although no environmental chamber data are available for this compound, there have been studies of its environmental fate (Wales, 2002, and references therein).... In PAGE 16: ... Although a gas-phase mechanisms for ozone reactivity assessment have not been developed for these compounds, as discussed by Finlayson-Pitts and Pitts (1997) there are kinetic and product data available for their atmospheric reactions. The other previously unstudied compounds listed on Table1 consist of various sulphur-, nitrogen- and in some cases chlorine- and phosphorous-containing compounds with varying degrees of volatility. The most volatile of these are the thiocarbamates molinate, EPTC and pebulate.... In PAGE 18: ... Table1 (continued) 9 SAPRC-99 [c] Compound or Mixture [a] CAS # Mass fract. [a] Vapor Pressure (ppm) [b] Model Species Unc.... In PAGE 19: ... Table1 (continued) 10 SAPRC-99 [c] Compound or Mixture [a] CAS # Mass fract. [a] Vapor Pressure (ppm) [b] Model Species Unc.... In PAGE 20: ... Table1 (continued) 11 [e] This compound is not part of the standard SAPRC-99 mechanism because it requires chlorine chemistry to be represented. No uncertainty code assigned, but it is probably equivalent to 2 or 3 when chlorine chemistry is implemented.... In PAGE 21: ... This is particularly the case for the aromatics, where ozone reactivities can vary significantly from isomer to isomer, and where data for higher molecular weight isomers are highly limited (Carter, 2000a). Of the hydrocarbon mixtures listed on Table1 , those with the most uncertain ozone impacts are probably Aromatic 200 and kerosene. Many of the pesticides listed on Table 1 are either nonvolatile or have very low volatility, which means that probably reaction of the compound itself is not important in affecting atmospheric ozone.... In PAGE 21: ... Of the hydrocarbon mixtures listed on Table 1, those with the most uncertain ozone impacts are probably Aromatic 200 and kerosene. Many of the pesticides listed on Table1 are either nonvolatile or have very low volatility, which means that probably reaction of the compound itself is not important in affecting atmospheric ozone. However, when assessing the atmospheric impacts of pesticide use, it is also important to consider impacts of volatile products that might be formed when pesticides break down in the soil.... In PAGE 21: ... Based on the above considerations, and after discussions with the staff of the CARB and the California Department of Pesticide Regulations, it was decided that the highest priority compounds to study for assessing ozone impacts of pesticides are MITC, the 1,3-dichloropropenes, kerosene, EPTC and carbon disulfide. The results for EPTC may also be useful as a basis for estimating ozone impacts of the other thiocarbamates listed in Table1 . The results of experiments, mechanism development, and model analyses of ozone impacts of these materials are discussed in this report.... In PAGE 36: ... These include representative compounds methyl isothiocyanate (MITC), carbon disulfide, S-ethyl N,N-di-n-propyl thiocarbamate (EPTC), and the 1,3- dichloropropenes that were studied in the chamber experiments for this project, and the additional representative pesticide compounds whose atmospheric reactivities were also calculated for this project. The compounds listed include those that were studied in the chamber experiments for this project, and volatile pesticide compounds listed in Table1 whose atmospheric ozone impacts were assessed for this project. Most of the individual compounds used to represent the constituents of kerosene are already included in the SAPRC-99 mechanism as documented (Carter, 2000a), but some compounds may have been added subsequently so a complete listing of their reactions is given in Appendix B to this report.... In PAGE 49: ... As shown on Table 3 and Table 4 mechanisms for the other thiocarbamate pesticides pebulate, molinate, and thiobencarb are also derived as part of this project. (The structures of these compounds are shown on Table1 .) Based on the data of Kwok et al (1992) for other thiocarbamates we assume that reaction with OH and NO3 radicals are the only atmospherically important loss processes.... In PAGE 59: ... Note that since the representation is on a mole-for-mole basis, the molecular weight of the actual carbon number is used when determining the number of moles of C16 compound to use when representing a given weight fraction of C17+ compound. Table 12 shows the number of moles of each type of alkane category derived from the weight fraction data in Table1 1, and the specific chemical compounds whose mechanisms are used to represent their atmospheric reactions. The mechanisms of these compounds are in Appendix B to this report.... In PAGE 62: ... Based on analyses of various petroleum distillate samples, primarily by Censullo et al (2002), Carter and Malkina (2005) derived distributions of various types of C8-C11 aromatics for the purpose of deriving atmospheric reactivities. These are summarized on Table1 3, which also shows the distributions of aromatic carbon numbers for the kerosene sample studied in this project, and also the methods used to represent them in the model calculations. Because of limited compositional data for mixtures of C12+ aromatics, Carter and Malkina (2005) had no distribution assignments for carbon numbers greater than 12.... In PAGE 63: ... The mechanisms used in the atmospheric reactivity for the chlorine-containing test compounds (the dichloropropenes and chloropicrin) included the chlorine mechanism that is discussed in Appendix A. The reactivity of kerosene was calculated using the mixture of model species given in Table1 2, with the mechanisms for these model ... In PAGE 74: ... However, it is of interest to determine the consistency of the data obtained in our reactivity experiments with the rate constants used in the chemical mechanism used in this study. The dichloropropene and m-xylene data from the dichloropropene reactivity experiments that can be used to derive estimated OH rate constants are summarized in Table1 6, and plots of Equation (II), assuming no unimolecular loss processes, are shown on Figure 11 for the two isomers. The figure also shows the lines where the data are predicted to fall using the OH rate constants of Tuazon et al (1988), which are the values used in the mechanism for these compounds.... In PAGE 90: ...81 Chloropicrin As indicated on Table1 chloropicrin is an important pesticide in California, so estimations of its ozone impact is of relevance to this project. It was not studied experimentally for this project because it was already studied by Carter et al (1997a,b), who also developed a mechanism for this compound that was reasonably consistent with the chamber data obtained.... In PAGE 96: ... Atmospheric Reactivity Calculations Calculated atmospheric ozone impacts of the selected pesticide-related compounds and mixtures in the MIR, MOIR, and EBIR incremental reactivity scales are shown in Table 20. This includes all the pesticide-related compounds listed in Table1 whose mechanisms have already been developed and are already on existing reactivity tabulations (Carter, 2000a, 2003a), and the pesticide-related compounds or mixtures whose mechanisms were developed and evaluated or estimated for this project. The mechanistic uncertainty classifications for the mechanisms used to calculate the reactivities, using the approach adopted previously (Carter, 2000a, 2003a) are also shown.... In PAGE 101: ... However, use of detailed compositional data is the preferred method to derive MIRs if such data are available. Other than these complex mixtures, the only compounds on the California pesticide profile list on Table1 that do not have reactivity estimates all have estimated vapor pressures of less than ~30 ppb at 25oC. Compounds with such low vapor pressures may not have sufficient volatility to participate in gas- phase reactions....
