permanganate, peroxides, nascent hydrogen, reducing agents and water.
Hazardous decomposition products
Lead compounds exposed to high temperatures will likely produce toxic metal fume, vapor or dust; contact with strong acid/base
or presence of nascent hydrogen may generate highly toxic arsine gas.
Sulfuric acid: Sulfur oxides (SOx).

Information on toxicological effects
Symptoms
Symptoms of lead toxicity include headache, fatigue, abdominal pain, loss of appetite,
muscular aches and weakness, sleep disturbances and irritability. Lead absorption may
cause nausea, weight loss, abdominal spasms, and pain in arms, legs and joints.
Effects of chronic lead exposure may include central nervous system (CNS) damage,
kidney dysfunction, anemia, neuropathy particularly of the motor nerves with wrist drop, and
potential reproductive effects.
Delayed and immediate effects as well as chronic effects from short- and long-term exposure
Skin Corrosion/Irritation
No data available.
Serious Eye Damage/Eye Irritation
No data available.
Sensitization
No data available.
Germ Cell Mutagenicity
The evidence for genotoxic effects of highly soluble inorganic lead compounds is
contradictory, with numerous studies reporting both positive and negative effects.
Responses appear to be induced by indirect mechanisms, mostly at very high
concentrations that lack physiological relevance.
Carcinogenicity
Sulfuric acid: The International Agency for Research on Cancer (IARC) has classified
“strong inorganic acid mist containing sulfuric acid” as a Category 1 carcinogen, a
substance that is carcinogenic to humans. This classification does not apply to liquid
forms of sulfuric acid or sulfuric acid solutions contained within a battery. Batteries
subjected to abusive charging at excessively high currents for prolonged periods without
vent caps in place may create a surrounding atmosphere of the offensive strong inorganic
acid mist containing sulfuric acid.
Lead: There is evidence that soluble lead compounds may have a carcinogenic effect,
particularly on the kidneys of rats. However, the mechanisms by which this effect occurs
are still unclear. Epidemiology studies of workers exposed to inorganic lead compounds
have found a limited association with stomach cancer. This has led to the classification by
IARC that inorganic lead compounds are probably carcinogenic to humans (Group 2A).
Arsenic: An increased lung cancer mortality was observed in multiple human populations
exposed to arsenic primarily through inhalation. Also, increased mortality from multiple
internal organ cancers (liver, kidney, lung, and bladder) and an increased incidence of skin
cancer were observed in populations consuming drinking water high in inorganic arsenic.
