The Changing Pattern of Suicide by Gassing in Australia, 1910-1987: The Role of Natural Gas and Motor Vehicles
Burvill P W
The use of gas as a suicide method has increased in the 1900s, the most marked increase being the use of motor vehicle exhaust fumes & the intro of natural gas in the early 1960s. In males, motor vehicle exhaust fumes substituted for use of domestic gas. In neither sex did the elimination of toxic CO in domestic gas, with the intro 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.
