Acute toxicity (mist) Description
Skin corrosion/irritation:

Serious eye damage/irritation:

Respiratory sensitization
Skin sensitization::

Germ cell mutagenicity:

Carcinogenicity:

Causes severe skin burns
Sulfuric acid is corrosive and irritating and produces direct local
effects on the skin, eyes and gastrointestinal tract after exposure
to sufficient concentrations. Exposure at high concentrations
rapidly destroys tissues, resulting in severe burns. Thus, it wasclassified into category 1B.
Causes serious eye damage
Skin corrosion/irritation is classified as category 1B. So it wasclassified into category 1.
Classification not possible
No classification
In general, severe skin irritation and burns are known topredispose to contact allergy, but there have been no reports ofskin irritation or secondary skin sensitization due to burns after
exposure to sulfuric acid. Therefore, it was classified as "Noclassification".
Classification not possible
In In vitro, reverse mutation tests with Salmonella typhimurium andEscherichia coli have been negative, and chromosomal aberration
tests with Chinese hamster ovary (CHO) cells have been positive,
but have been shown to result from low pH of the culture medium.
Classification not possible
It was concluded that IARC is carcinogenic to humans (Group-1)
following occupational exposure to strongly inorganic acid mists,
including sulfuric acid. This classification applies to mists (oraerosols) and not to sulfuric acid itself. Sulfate aerosols at
sufficiently high concentrations are frequently deposited in thenasopharyngeal and/or laryngeal regions, where they repeatedly
cause injury, inflammation, and repair. It is presumed that thisresults in cell proliferation and, in conjunction with othercarcinogens, effects (weak effects associated with sulfate
exposure: repeated irritant effects). As an example to allow the
speculation of deposition in these predilection sites and extreme
local-induced effects, squamous metaplasia and persistent
proliferation of the larynx have been seen in a 28-day repeatedinhalation exposure study in rats.

Reproductive toxicity:

STOT-single exposure:

STOT-repeated exposure:

Aspiration hazard:

No classification
In a developmental toxicity study (gestational days 6-15) in micefollowing inhalation, no developmental effects were observed in thefetuses of dams up to high doses (19.3 mg/m3) with reduced foodconsumption (Day 1 only) and reduced liver weights. Also, noreports are available on the reproductive toxicity of sulfuric acidby the oral, dermal or inhalation routes of exposure in laboratory
animals. However, since sulfuric acid has irritant/corrosive
effects, it is not appropriate to test for reproductive effects by
the oral and dermal routes. Sulfuric acid is a poison that acts
directly at the site of contact. It is considered that the aciditself is not absorbed and distributed to the whole body.
Therefore, it is unlikely that sulfuric acid will reach thereproductive organs of both sexes as sulfuric acid after exposureby any route. It has been reported that ionized sulfate ion may be
excreted in the urine in excess as a normal metabolite of sulfurcontaining amino acids and may not play a specific toxicologicalrole. Therefore, it was classified as "No classification".
Causes damage to organs (respiratory organs)
There are case reports of cough, dyspnea (sometimes with spasm of
the vocal cords), and bronchitis following nasal discharge,sneezing, and burning sensation behind the throat and sternum inhumans who inhaled sulfuric acid. At high exposure levels, nasal
discharge and sputum mixed with blood, hemoptysis and gastritis
were observed. In addition to these, there are numerous casereports of respiratory symptoms resulting from inhalation exposure
to sulfuric acid. In addition, in a single inhalation exposure
study in volunteers, coughing was reported in humans who exercised
while deeply inhaling sulfuric acid at 0.38 mg/m3 or higher duringexposure, and in volunteers after 24 hours of exposure to sulfuric
acid in 0.45 mg/m3, it was reported that increased respiratory
tract responses were observed in those volunteers, and it wasreported that throat irritation was caused by 0.45 mg/m3 and 1.0
mg/m3 exposure. It has been reported that exposure to sulfate
levels greater than or equal to 3 mg/m3 resulted in rattle andbronchoconstriction. Therefore, it was classified as category 1(respiratory organs).
Causes damage to organs (respiratory organs) through prolonged orrepeated exposure
In a 28-day repeated inhalation (mist) exposure study (6 h/day, 5days/week) in rats (females), squamous metaplasia of the larynx was
observed at 0.3 mg/m3 (guidance conversion value: 0.000067 mg/L/6h,
range 1) or higher, and cellular proliferation of the laryngeal
epithelium was reported at 1.38 mg/m3 (guidance conversion value:
0.0003 mg/L/6h, range 1) or higher. In an 82-day repeated-dose
inhalation study (8 hours/day) in male rats, it was reported that
alveolar epithelial cells (mainly alveolar ducts) were
hypertrophied at 2 mg/m3 (guideline conversion: 0.0018 mg/L/6h,
Category 1) or higher. Therefore, it was classified as category 1(respiratory organs).
