Atmosphere of Triton Atmosphere of Triton The atmosphere of Triton is the layer of gases surrounding Triton. The surface pressure is only 14 microbars (0.014 hPa or 1 mmHg), of the surface pressure on Earth, and it is composed of nitrogen, similar to those of Titan and Earth. It extends 800 kilometers above its surface. Recent observations have shown an increase in temperature. Nitrogen is the main gas in Triton's atmosphere. The two other known components are methane and carbon monoxide, whose abundances are a few hundredths of a percent of that of the nitrogen. Carbon monoxide, which was discovered only in 2010
Suicide in the United Kingdom (4 per cent). Hanging is the most common method used by women, closely followed by self poisoning. Inhalation of domestic gas was the most common method of suicide during the mid-twentieth century. It was completely eliminated by the 1990s as a result of the replacement of coal gas containing toxic carbon monoxide by the non-poisonous natural gas. Later, suicide by inhalation of carbon monoxide from car exhausts became common, but has declined since the introduction of catalytic converters. Age-standardised rates generally fell between 1981 and 2007, with rates in subsequent years increasing to reach a peak of 11.1 deaths per
