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...
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, ...
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 squirts (ascidians). More biological data... Sulfur: uses Uses......
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...

Sulfur dioxide is a heavy, colourless, poisonous gas with a pungent, irritating odour familiar as the smell of a just-struck match. Occurring in nature in volcanic gases and in solution in the waters of some warm springs, sulfur dioxide usually is prepared industrially by the burning in air...
Triglyceride hydrolysis and oxidation yield products that give rise to the smell and taste of rancidity [60,61], whereby even 5% triglyc eride hydrolysis can render a batch completely unusable for animal feed applications [62] Once this has occurred, the rancidified animal fats must be disposed...
