||Assessment of the toxicity of major hazard substances

||This paper proposes a systematic approach for expressing the toxicological hazard to human health posed by the airborne release of a major hazard substance. The importance of using reliable toxicity data from original sources is discussed. Criteria defining the level of toxicity on which risk calculations are based are described in terms of individual risk, i.e. the likelihood of an individual receiving an exposure which will produce a specified level of toxicity, and societal risk, the frequency of a given number of deaths from a specific cause. A method is described for deriving the relationship between the atmospheric concentration of the substance and the duration of exposure for a given level of toxicity. The parameters thus deemed may be used in major hazard risk analysis.
