Ewww that smell Salts, sulfur compounds, and gases are among the substances that can be dissolved in the spring water during its passage underground. Mineral springs of Kyrgyzstan Scientists at North Carolina State University clarified the source and formation of volatile sulfur compounds in fluid mi...
H2S is the only form of sulfide that is volatile and it imparts a characteristic “rotten egg” smell to sediments at low tide. Dissolve sulfides react strongly with base and transition metal ions to form insoluble sulfide minerals, the most prominent of which are iron sulfides that make ...
garlic odor, and skunk spray, as well as a component of bad breath odor. Not all organic sulfur compounds smell unpleasant at all concentrations: the sulfur-containing monoterpenoid grapefruit mercaptan in small concentrations
Smell is unreliable for detection. In heavily contaminated areas, the odour may be readily perceptible on first encounter but the sense of smell fatigues rapidly (Moncrieff, 1951) and within 10 min, the presence of the chemical ceases to be appreciated. Thus, HD does not irritate the eyes, ...
hydrogen sulfidehydrogen sulfide is a hydride of sulfur with the chemical formula H2S. A colorless, highly toxic gas with a bad odor (the smell of a bad egg). Soluble in water and ethanol, the specific gravity of 1.1906. Melting Point -85.5°C, boiling point -60.4°C, critical temperature...

but in higher concentrations it kills quickly by preventing respiration. It is insidious in that it deadens the sense of smell quickly, meaning victims may be unaware of its presence. It is more toxic than cyanide. Remarkably, sulphuric acid (H2SO4) is present in the digestive fluids of sea...
A red fuming liquidwith a strong smell. It is prepared by passingchlorine over molten sulfur and is usedto harden rubber. 3.2 Methods of Manufacturing In the synthesis method, the sulfur powder is first put into the jacket reactor, and then heated by steam, and at the same time, a small...
