text: The median lethal dose (LD 50 )—the exposure required to kill half of a tested population—as estimated for 70 kg human males via exposure to the skin is reported to be 5 - 10 mg (0.00035 oz), and the lethal concentration time (LCt 50 ), measuring the concentration of the vapor or aerosol per length of time exposed, is estimated for VX to be 10 - 15 mg·min/m3 for exposure time of two minutes at a minute volume of 15 l (minute volume of 15 l corresponds to slight physical activity like slow walking).
