(2002)), there was the description that no kidney damage in
the subsequent epidemiologic study in the same source of
reference. Therefore, the data is insufficient for considering
the kidney as target organ, therefore, it is classified as
"classification not possible".
Specific target organ toxicity
(repeated exposure) :
Due to the descriptions that the target organs were
hematopoietic system, nervous system, kidney, and
cardiovascular system in DFGOTvol.17 (2002), that heme
synthesis inhibitors, nephropathy and brain diseases were
observed in the human exposure examples in EHC 3
(1977), ACGIH (7th, 2001), PATTY (4th, 1994), and IARC
23 (1980), that it affects to the peripheral nerve and function
of central nerve system in humans exposure examples in
EHC 3 (1977), ACGIH (7th, 2001), PATTY (4th, 1994), that
it affects to cardiovascular system, such as high blood
pressure in human exposure examples in EHC 3 (1977),
ACGIH (7th, 2001), that the immunosupressive effect was
observed in human exposure examples in PATTY (4th,
1994), it is considered that the target organs were
hematopoietic system, the kidney, central nervous systems,
peripheral nervous system, cardiovascular system and
immune system, and they all were classified as “Category 1
of GHS Specific target organ toxicity (repeated exposure)”.
Although there are the descriptions of the case reports of
thyroid or adrenal hypofunctions in EHC 3 (1977), each
case reports are before 1970, and there is no similar report
after that, since there is the description that no effects was
observed in the thyroid in DFGOTvol.17 (2002), the thyroid
and the adrenal gland were not considered as for target
organs.
Aspiration hazard :
No data.
Others :
No information.
○Lead dioxide (electrode plate)
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 :
Since there is the description of "Probably a severe eye,
skin, and mucous membrane irritant "(HSDB (2006)), it is
considered that indicate severe irritation to skin. Therefore,
it was classified as Category 2 of GHS Skin
