1. Mercury sulphide reacts with oxygen to form mercury vapour and sulphur dioxide. 2. :: Another common treatment was sitting in a fog of mercury vapours . 3. Fluorescent lighting relies on mercury vapour for its operation. 4. See, for example, mercury vapour turbine. 5. The bladders containing the mercury soon ruptured and the crew were poisoned by mercury vapour . 6. Fluorescent lamps consist of a glass tube that contains mercury vapour or argon under low pressure. 7. One of these lamps is a neon tube and the other a tube containing mercury vapour and helium. 8. In 1985 this changed; although the fittings were retained, they were converted from gas to mercury vapour usage. 9. Metallurgical developments have allowed steam-only plants to increase in efficiency over time, making the mercury vapour turbine obsolete. 10. Mercury is effective in extracting very small gold particles, but the process is hazardous due to the toxicity of mercury vapour .
