The relationship between wind speed and the potency of GB and VX vapour for the production of miosis has been studied in rabbits and humans. Changes in windspeed have a small effect on the degree of miosis produced by GB vapour. The Ct to produce 90 miosis in humans at a wind speed of 0.01 ms is 10 mg mincu m and at 2 ms is 4 mg mincu m with VX vapour, however, the Ct to produce 90 miosis falls from 7 mg mincu m at 0.01 ms to 0.09 mg mincu m at 2 ms. This difference between the effects of GB and VX vapour at varying wind speeds can be explained in terms of the physico-chemical properties of the two agents. A mathematical model has been developed which gives good agreement with experimental results.
