There have been large changes in the use of gas as a suicide method in Australia during this century, the most marked being the increased use of motor vehicle exhaust fumes, and the introduction of natural gas in the early 1960s. In males, use of motor vehicle exhaust fumes as a suicide method has substituted for use of domestic gas. It was concluded that in neither sex did the elimination of toxic carbon monoxide in domestic gas, with the introduction of natural gas, result in a lasting reduction of suicide rates. Attention is drawn to possible failed suicide attempts using motor vehicles with emission controls, resulting in serious cerebral damage.
在本世纪，澳大利亚使用煤气作为自杀手段的情况发生了很大变化，最显著的是机动车尾气排放物的使用增加，以及20世纪60年代初天然气的引入。在男性中，使用机动车尾气排放物作为自杀手段已取代了使用家用煤气。得出的结论是，对于男性和女性而言，随着天然气的引入，家用煤气中有毒一氧化碳的消除都没有导致自杀率的持续下降。需要注意的是，使用装有排放控制装置的机动车进行自杀未遂可能会导致严重的脑损伤。
