and amino acid urine is reported. Inorganic lead affects on
the peripheral nervous system, in particular, muscle
weakness in limbs, pain and convulsions are observed. In
addition, although it is very rare case in adults, in case of
being exposed to extremely high concentrations (details
unknown), the effects on the central nervous system are
observed such as ataxia, headache, paresthesia,
depression and coma.
However, in effects on the central nervous system,
particularly sensitive in children, and the symptoms with no
restless, aggressive personality, difficulty concentrating,
decline of memory and the like have become a problem in
the U.S." (CERI Hazard Assessment Report
2001-9(2002))
Therefore, blood system, kidney and nervous system are
considered to be target organs. From the above, it was
classified as "Category 1 of GHS Specific target organ
toxicity (single exposure, repeated exposure) (blood
system, kidney, nervous system)".
Aspiration hazard :
No data.
Others :
No information.
○Lead sulfate (electrode plates)
Acute toxicity (Oral) :
No data.
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) :
No data.
Acute toxicity
(Inhalation: Dust and Mists) :
No data.
Skin corrosion/irritation :
No data. As effects on humans, although there is no data
that can be obtained for local effects on the skin and
mucous membranes by lead and inorganic lead
compounds, there is the description of that there is likely to
cause severe irritation and burns to the skin.
Serious eye damage/eye irritation :
No data. As effects on humans, although there is no data
indicating the local effects on the mucous membranes by
lead and inorganic lead compounds, there is the description
of that there is likely to cause severe irritation and burns to
the eye.
Respiratory or skin sensitization :
No data.
Germ cell mutagenicity :
It is “Classification not possible” due to insufficient data of in
vivo test. In addition, in the in vitro test, there is the negative
report in Ames test. Moreover, although it may not be
