This memorandum presents a drinking water assessment to support spirodiclofen (Envidor (R) 2 SC) miticide use on citrus, pome fruits, stone fruits, tree nuts crops, and grapes. The models, Pesticide Root Zone Model, Exposure Analysis Modeling System (PRZM/EXAMS) and Screening Concentrations In Ground Water Model (SCIGROW) were used in estimating the total residue concentrations of spirodiclofen in surface water and groundwater respectively. The Estimated Drinking Water Concentrations (EDWCs) of spirodiclofen and its three metabolites (spirodiclofen-enol, spirodiclofen-ketohydroxy and spirodiclofen-dihydroxy) were computed using  application rates of 0.53 to 0.28 lbs. a.i./Acre on multiple crops. Tier II surface water modeling of  Florida citrus scenario using the index reservoir with the default percent cropped area (PCA=0.87) predicts the 1 in 10 year peak (acute) concentration of spirodiclofen residues is not likely to exceed 23.86 μg/L. The 1 in 10 year annual average concentration (non-cancer chronic) and 30 year annual average concentration (cancer) of spirodiclofen residues is not likely to exceed 4.99 and 1.67 μg/L, respectively. Tier I  SCIGROW model was used in generating groundwater EDWCs for the highest application rate of 0.53 lbs. a.i./A and the resulted concentration is 0.43 μg/L for spirodiclofen residue, which is recommended to use for both acute and chronic exposures. The EDWCs for surface and ground water resources are presented in Table 1. An electronic PRZM/EXAMS time-series output file of PCA adjusted daily EDWCs for surface water for Florida citrus scenario was also provided to Tom Bloem, Health Effects Division (HED).

1.0 ESTIMATION OF SURFACE WATER AND GROUNDWATER EXPOSURE  CONCENTRATIONS
                                    
A cumulative residue modeling approach was used to account for the environmental fate and transport of spirodiclofen and its degradation products (spirodiclofen-enol, spirodiclofen-ketohydroxy and spirodiclofen-dihydroxy) with toxicological concern. These residues were designated by the HED's  Metabolite Assessment Review Committee (MARC) as being spirodiclofen  residues of human-health toxicological concern. Linear fitting techniques using the first order degradation model (y = -bx + a) was used in calculating  the combined residue half-lives. The Envidor (R) 2 SC label application rates and the environmental fate parameters for spirodiclofen residue  were used in estimating EDWCs using  two screening models PRZM/EXAMS, shell PE4V01a (8/13/03) for surface water and SCIGROW v.2.3 (7/29/03) for groundwater.  The outputs of the two screening models represent estimates of the concentrations that might be found in surface water and groundwater due to the use of spirodiclofen. Several scenarios (apple, citrus, peaches, grape, and pecan) were investigated and the Florida citrus provided the highest EDWCs among the modeled scenarios (Table 2).

2.0 Background Information on PRZM/EXAMS 

The linked PRZM and EXAMS model (PRZM/EXAMS) is typically used by the Environmental Fate and Effects Division (EFED) in estimating pesticides concentrations in surface waters. PRZM is employed to evaluate runoff loading to a  receiving surface water body. As soon as the pesticide residues reaches the surface water, EXAMS uses algorithms to the pesticides concentrations by taken into account different dissipation mechanism in the aqueous and sediment phases.

PRZM is a one-dimensional finite-difference modeling system that was originally developed to model nitrogen soil kinetic processes and groundwater environment. It was later enhanced to expand its capability to predict pesticides transport and transformation down through the crop zone and saturated zone. The expanded capabilities cover additional phenomena such as soil temperature simulation, microbial transformation, vapor phase transport in soils, volatilization, irrigation simulation, and a method of characteristics (MOC) algorithm to eliminate numerical dispersion.

EXAMS is a model that has a set of process modules that link fundamental chemical properties to limnological processes that control the kinetics and transport of chemicals in aquatic systems. It provides facilities for steady state or long-term evaluation of chronic chemical discharges, initial-value approaches for studying short-term contaminant releases, and full kinetic simulations that allow for monthly variation in mean climatological factors, and changes in contaminant loadings on daily time scales. It is fairly and relatively complex model that requires more input variables, ranging from hydro-geological and weather data to pesticide physicochemical properties, mobility coefficients, and degradation rate constants in the aqueous and sediment phases.

3.0 Background Information on SCI-GROW

SCIGROW is a regression-based model that provides a groundwater screening exposure value to be used in determining the potential risk to human health from drinking water contaminated with the pesticide. SCIGROW estimates likely groundwater concentrations if the pesticide is used at the maximum allowable rate in areas where groundwater is exceptionally vulnerable to contamination. 

4.0 Uncertainties, Assumptions, and Limitations

Uncertainties, assumptions, and limitations of the simulation modeling are as follows:

 A major uncertainty in the assessment is the lack of environmental fate data for the toxic transformation products of spirodiclofen.  In order to address this uncertainty, EFED has conducted the Tier II  modeling on the summed spirodiclofen residues instead of individual residues. This approach was taken because the environmental fate studies were deficient in addressing the identification and fate of spirodiclofen transformation products.

 The cumulative residue modeling method assumes environmental fate properties for spirodiclofen and its degradation products (spirodiclofen-enol, spirodiclofen-ketohydroxy and spirodiclofen-dihydroxy) are similar.  This modeling approach provides a conservative assessment process for consideration of simultaneous formation and decline of spirodiclofen  residues.  However, it is likely to provide conservative estimates because minor degradation products (<10% of applied) may dictate the environmental fate properties for all spirodiclofen residues

 The adsorption coefficient and solubility of  spirodiclofen-enol was used because it has the lowest average Koc and highest solubility. These properties may provide conservative estimates because low Koc and high solubility may dictate the runoff load for all spirodiclofen residues.

 PRZM-EXAMS scenarios are regionally representative for each crop. They may not represent the most conservative runoff or spray drift situation for each and every crop.  It is assumed focusing on several scenarios in higher runoff areas such as the eastern United States will capture upper end spirodiclofen residue concentrations in drinking water.

 Spirodiclofen is a new chemical. Monitoring data are not available to evaluate the prediction potential of PRZM/EXAMS and SCIGROW simulation modeling. 

5.0 Modeling Inputs and Results:

Tables 3 and 4 summarize the spirodiclofen input values used in the model runs for PRZM/ EXAMS and SCIGROW, respectively. PRZM /EXAMS and SCIGROW modeling results are presented in Table 1 and 2. This memo also contains the copies of the outputs generated from the PRZM/EXAMS and SCIGROW models (Appendix A). Appendix A-2 has a truncated PRZM/EXAMS daily time-series output file.

APPENDIX B.  Half-life Calculation Methods for Spirodiclofen Total Residue Analysis

First-order linear regression analysis
Half-lives were calculated using natural log-transformed (weighted) concentration data from all samples that were greater than the detection limit and using all sampling intervals.  A regression line is fitted for the data using the first-order two-parameter linear regression equation:

      y = -bx + a

where a is the y-intercept and b is the rate constant (slope).
