Abstract

Varying concentrations of DDT in solution in different solvents were tested by painting copper screen wire of 18 meshes per inch. Tests were made at varying time intervals after painting, the tested wire being kept under differing conditions of exposure.

The aims of the experiments were to demonstrate the following points;

  • 1.  The length of contact with the painted wire required to kill within selected subsequent arbitrary time period.
  • 2.  The original lethal effect of the newly painted wire and the period over which subsequent lethal effect would persist.
  • 3.  The effect of different DDT solvents on primary lethal effect, and the duration of lethal effect as modified by different solvents.
  • 4.  The effect of varying concentrations of DDT in different solvents on the primary lethal effect, and the duration of lethal action.
  • 5.  The influence of different types of “weathering” on the lethal effect of DDT in solution.
