Despite common belief that SO 2 was the main source of the asthma, by investigating sulfur dioxide and sulfur trioxide levels in Yokkaichi and analyzing compound toxicity levels, a study conducted in 1984 from Yokohama National University concluded that respiratory diseases were not a result of sulfur dioxide, but rather due to a titanium oxide ...
[1] [2] Smoke, chlorine, phosgene, sulfur dioxide, hydrogen chloride, hydrogen sulfide, nitrogen dioxide, ozone, and ammonia are common irritants. Depending on the type and amount of irritant gas inhaled, victims can experience symptoms ranging from minor respiratory discomfort to acute airway and lung injury and even death.
The term immediately dangerous to life or health (IDLH) is defined by the US National Institute for Occupational Safety and Health (NIOSH) as exposure to airborne contaminants that is "likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment." Examples include smoke or other ...
Sulfur trioxide is a reagent in sulfonation reactions. Dimethyl sulfate is produced commercially by the reaction of dimethyl ether with sulfur trioxide: [20] CH 3 OCH 3 + SO 3 → (CH 3) 2 SO 4. Sulfate esters are used as detergents, dyes, and pharmaceuticals. Sulfur trioxide is generated in situ from sulfuric acid or is used as a solution in ...
It contains more than 4,000 chemicals, many of which are known to affect health. These may include ammonia, acrolein, carbon monoxide, hydrogen cyanide, nicotine, nitrogen oxides, arsenic, and sulfur dioxide, many of which contain irritants and toxicants to the eye and respiratory tract.
Like most toxic gases, the dose inhaled determines the toxicity on the respiratory tract. Occupational exposures constitute the highest risk of toxicity and domestic exposure is uncommon. Prolonged exposure to low concentration of the gas may have lethal effects, as can short-term exposure to high concentrations like chlorine gas poisoning.
Sulfur oxide refers to many types of sulfur and oxygen containing compounds such as SO, SO 2, SO 3, S 7 O 2, S 6 O 2, S 2 O 2, etc. Sulfur oxide (SO x) refers to one or more of the following: Lower sulfur oxides (S n O, S 7 O 2 and S 6 O 2) Sulfur monoxide (SO) and its dimer, Disulfur dioxide (S 2 O 2) Sulfur dioxide (SO 2) Sulfur trioxide (SO 3)
The effects of sulfur trioxide and sulfuric acid are similar because they both produce sulfuric acid when they come into touch with the wet surfaces of your skin or respiratory system. [97] The amount of SO 3 breath through the mouth is larger than the amount of SO 3 breath through the nose. [97]
