Evaluation of a Method for Field Collection of Ultra-Low Volume-Size Aerosol Droplets

Abstract

Studies were conducted to develop practical alternates to the hand-wave method for the field collection of ULV-size aerosol droplets. A comparative evaluation between the hand-wave method and settling chambers was made using aerosol droplets of malathion or Klearol, produced by a Micro-Gen MS2W-15, collected on Teflon-coated microscope slides. Settling chambers included large metal US Army shipping containers (MILVANS) and smaller plywood boxes of various dimensions. Results indicated an increased efficiency of the settling technique versus the hand-wave method in the collection of droplets less than 10 micrometers in size. Plywood settling chambers evaluated in this study appear to be a more practical and efficient method for the field evaluation of the aerosol producing efficiency of ULV insecticide sprayers.
