TI  - Predicted 1,3-dichloropropene air concentrations resulting from tree and vine 
      applications in California.
PG  - 1887-95
AB  - The preplant soil fumigant 1,3-dichloropropene (1,3-D) is effective for nematode 
      control and is expected to further replace methyl bromide (MeBr) as MeBr use is 
      phased out. Acute human exposure to soil fumigants is managed in part by using 
      buffer zones between treated fields and occupied structures. The required buffer 
      zone for 1,3-D in California is 91.4 m (300 ft) for all uses. However, a 30.5-m 
      (100-ft) buffer setback is desired for 1,3-D to be an important replacement for 
      MeBr in the orchard and vineyard markets. The Industrial Source Complex 
      Short-Term model, Version 3 (ISCST3) was used to simulate township-wide long-term 
      average and short-term air concentration distributions of 1,3-D. The Gaussian 
      plume model ISCST3 can be used to assess dispersion of air pollutants and 
      pollutant concentrations on receptors from a variety of sources and in diverse 
      airsheds. Long-term and daily-average air concentrations can be compared with the 
      California permitted chronic or acute toxicity endpoints, respectively, to assess 
      the potential risk for individuals living within the township at the proposed 
      buffer setback. Modifications to ISCST3 were made for specific nonpoint-source 
      agricultural constraints and management practices. Chronic and acute air 
      concentration distributions of 1,3-D with a 30.5-m buffer constraint around 
      treated fields are similar to currently permitted air concentration distributions 
      in California. Refinement of exposure as a function of buffer distance, 
      application rate, and field size is possible due to the resolution of the 
      simulation and external post-processing capabilities. Simulated examples of 1,3-D 
      acute and chronic exposure cumulative distributions are presented.
