Abstract

The relation between the exposure response to toxic gases, such as arsine, and the exposure time is almost non linear in a large domain of time. This non linear behaviour is especially visible when closer to the 0% lethal level, or closer to the 100% lethal level. An allometric behaviour has been displayed between the linear extrapolated exposure time corresponding to the 0% lethal level and the time corresponding to the medium of the linearity domain at a given concentration. Different methods have been used when displaying this allometry in order to ensure validity and reliability. Keywords: single exposure, arsine concentration, exposure time, lethal level, LC0%, fitting, data processing, linearity domain, tangential extrapolated LC0%, allometry.
