Sulfuric acid belongs to the non-metal sulfates, a subclass of non-metal oxoanionic compounds within the inorganic compounds. It has the molecular formula H2O4S and an average molecular weight of 98.08 g/mol. This exogenous compound is a liquid at room temperature.
In industrial applications, sulfuric acid serves as a catalyst, a pH regulating agent, a fragrance, a flavouring and nutrient, and as processing aids not otherwise specified (PMC13208812 , PMC8659934 ). It functions as an acid in both industrial and biological contexts (PMC7344730 , PMC9088909 ). Additionally, it is used in the production of Polyamide plastics.
The compound is found in or released from 68 recorded sources. These include household cleaning and consumer products such as bleaching agents, perfumes within detergents and soaps, and smoking requisites including cigar cigarettes and non-electric simulated smoking devices. It is associated with food and food processing, including the preparation of vinegar and malt, food preservation, and fermentation processes for beer. In building and construction, it is found in floors, ceilings, roofs, stairs, ramps, and fencing. Other sources include household items like coins and watch chains, as well as electrical and electronic equipment including antennas, amplifiers, coils, and adjustable resistors. Regarding health effects, sulfuric acid is associated with lung cancer (PMC12272563 ).
Belongs to the class of inorganic compounds known as non-metal sulfates. These are inorganic non-metallic compounds containing a sulfate as its largest oxoanion.
carcinogenic agent (PMC7470770 , PMC9482008 )?A role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.
Many strong acids cause tissue burns through the denaturation of proteins and partial hydrolysis of proteins. Most proteins denature at pH values of less than 3-4. The large-scale denaturation of proteins, de-esterification of lipids and subsequent desiccation of tissues leads to chemical burns. Symptoms include itching, bleaching or darkening of skin or tissues, blistering and burning sensations. More specifically, sulfuric acid readily decomposes proteins and lipids through amide hydrolysis and ester hydrolysis upon contact with living tissues. In addition, it exhibits a strong dehydrating property on carbohydrates, liberating extra heat and causing secondary thermal burns. The strong oxidizing property may also extend its corrosiveness on the tissue. Because of such reasons, damage posed by sulfuric acid is potentially more severe than that caused by other comparable strong acids, such as hydrochloric acid and nitric acid.
Occupational exposures to strong inorganic acid mists containing sulfuric acid are carcinogenic to humans (Group 1). (1)
Minimum Risk Level
The limit of exposure of sulfuric acid is fixed at 1 mg/m3.
Symptoms
Skin contact can cause redness, pain, blisters and severe skin burns. Sulfuric acid may cause severe burns to the eye and permanent eye damage. Severe and rapid corrosive burns of the mouth, gullet and gastrointestinal tract will result if sulfuric acid is swallowed. Symptoms include burning, choking, nausea, vomiting and severe pain.
Treatment
The mainstay of treatment of any acid burn is copious irrigation with large amounts of tap water. To be most effective, treatment should be started immediately after exposure, preferably before arrival in the emergency department. Remove any contaminated clothing. Do not attempt to neutralize the burn with weak reciprocal chemicals (i.e. alkali for acid burns), because the heat generated from the chemical reaction may cause severe thermal injury.
