Webof hydrogen sulfide is well known. At 20 ppm it causes irritation of the eyes and respiratory tract. Thirty minutes of exposure at 500 ppm causes severe sickness. Exposure at 1000 ppm for 30 minutes is fatal. The other components of NCG are similarly toxic. TRS concentration in concentrated NCG is 100,000 ppm or greater. WebIt usually has a calorific, or heating, value of approximately 38 megajoules (MJ; million joules) per cubic metre or about 1,050 ... However, some of the associated gases in natural gas, especially hydrogen sulfide, have a distinct and penetrating odour, and a few parts per million are sufficient to impart a decided odour to natural gas. ...
