[Toxicity of products resulting from the cold combustion of polypropylene].

The cool flame combustion of polypropylene at 350 degrees C leads to the formation of toxic compounds which can cause death in mice. Under the conditions described, the LD50 is close to 0.95 g. However the survival times with 0.50 g samples are longer than those obtained by operating in an ambient atmosphere at 500 degrees and 800 degrees C after a slow introduction of the material into the oven.

[Classification of harmful gases].

The classification of harmful gases may be envisaged in various ways according to the criteria considered. The two aspects adopted here concern chemical and toxicological classifications. Chemical classification is in general based upon the nature of the elements constituting the gases, e.g. carbon, nitrogen, sulphur, phosphorus, halogen compounds and halogenated compounds, etc. Toxicological classification is envisaged on the basis of the concepts of toxicity itself. It may then be used to establish the scale of its degree based upon two principal factors: concentration and duration of exposure. However, certain observations suggest complex intoxication phenomena related to an overall number of factors which are generally considered in isolation.
