11. Toxicological Information
Indicate the information for each of components of lead acid battery as below.
○Lead (electrode plate, terminal)
Acute toxicity (Oral) :
Acute Toxicity Estimate (ATE) = 500 mg/kg
It was classified as Category 4 of GHS acute toxicity (Oral).
Acute toxicity (Dermal) :
No data.
Acute toxicity (Inhalation - Gases) :
Classification not applicable because it is a solid in the
definition of GHS.
Acute toxicity (Inhalation - Vapors) :
Acute Toxicity Estimate (ATE) = 11 mg/l
It was classified as Category 4 of GHS acute toxicity
(Inhalation - Vapors)
Acute toxicity (Inhalation - Dusts and
Mists) :
No data.
Skin corrosion/irritation :
No data.
Serious eye damage/eye irritation :
No data.
Respiratory or skin sensitization :
No data.
Germ cell mutagenicity :
Although there are contradicting results about the
chromosome aberration in the peripheral blood
lymphocytes from people who are engaged in lead-related
work (IARC suppl.7 (1987), EHC 3 (1977), DFGOTvol.17
(2002), ACGIH (7th, 2001)), there are descriptions of lead
itself having chromosome aberration/micronucleus
inductive actions. Therefore, it was classified as Category 2
of GHS Germ cell mutagenicity.
Carcinogenicity :
From the below classifications, it was classified as Category
2 of GHS Carcinogenicity.
 IARC Supplement 7 (1987) and Japan Society for
Occupational Health: 2B
 ACGIH (7th, 2001): A3
 EPA (IRIS (1993)): B2
Reproductive toxicity :
Since there is the description that there is the affect for
sperm formation disorder in human exposure example
(EHC 3 (1977), ACGIH (7th, 2001), DFGOTvol.17 (2002)),
and ovulation dysfunction was observed in the female
occupation exposure example (EHC 3 (1977)), it was
classified as "Category 1A of GHS Reproductive toxicity".
There are the descriptions about the relationship with
neonatal developmental disorder of cognitive function
(ACGIH (7th, 2001), DFGOTvol.17 (2002), PATTY (4th,
1994) and IARC 23 (1980)), and the descriptions about the
relationship with the increase of miscarriage (DFGOTvol.17
(2002), and PATTY (4th, 1994)). However, the distinct
conclusion has not obtained.
Specific target organ toxicity
(single exposure) :
Although there was a case report that renal dysfunction was
observed in the acute toxicity in human (DFGOT, vol.17
