The role of sulfur dioxide, SO 2, in mammalian biology is not well understood. [30] Sulfur dioxide blocks nerve signals from the pulmonary stretch receptors and abolishes the Hering–Breuer inflation reflex. Sulfur dioxide plays a role in diminishing an experimental lung damage caused by oleic acid. Endogenous sulfur dioxide lowered lipid ...
Sulfur dioxide is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. The method of converting sulfur dioxide to sulfuric acid is called the contact process. Several million tons are ...
Other inhaled agents may be directly toxic (e.g. cyanide, carbon monoxide), or cause harm simply by displacing oxygen and producing asphyxia (e.g. methane, carbon dioxide). The effect of inhaling irritant gases depends on the extent and duration of exposure and on the specific agent [22] [23] [24] Chlorine, phosgene, sulfur dioxide, hydrogen ...
Smog is a serious problem in many cities and continues to harm human health. [30] [31] Ground-level ozone, sulfur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma.

The blistering effects of mustard gas can be neutralized by decontamination solutions such as "DS2" (2% NaOH, 70% diethylenetriamine, 28% 2-methoxyethanol). [medical citation needed] For skin lesions, topical treatments, such as calamine lotion, steroids, and oral antihistamines are used to relieve itching. [4]
It is a rare blood condition in which the β-pyrrole ring of the hemoglobin molecule has the ability to bind irreversibly to any substance containing a sulfur atom. [ 1 ] [ 2 ] When hydrogen sulfide (H 2 S) (or sulfide ions ) and ferrous ions combine in the heme of hemoglobin, the blood is thus incapable of transporting oxygen to the tissues.
The USGS said the primary concern is high levels of volcanic gas – primarily water vapor, carbon dioxide and sulfur dioxide – that could have "far-reaching effects down-wind."
The amount of sulfur dioxide that can be emitted into the atmosphere is capped by the EPA. This reduces the quantity of sulfur dioxide in the air that turns into sulfur trioxide and sulfuric acid. [14] Sulfuric acid concentrations in workroom air are restricted by OSHA to 1 mg/m 3. Moreover, NIOSH advises a time-weighted average limit of 1 mg/m ...
