Model to predict aerial dispersal of bacteria during environmental release.

摘要: Risk assessment for genetically engineered bacteria sprayed onto crops includes determination of off-site dispersal and deposition. The ability to predict microbial patterns is essential characterize the uncertainty (risk) associated with environmental release recombinant organisms. Toward this end, a particle model was developed recovery on fallout plates at various distances directions about test site. microcomputer simulation incorporates size distribution, wind speed direction, turbulence, evaporation, sedimentation, mortality, time step 0.5 s. tested against data reported from three field applications nonrecombinant two bacteria. Simulated 10(5) particles compared deposition measurements. may be useful in defining appropriate populations organisms release, methods or application, characteristics site that influence containment dispersal, developing an sampling methodology monitoring such as
