(Leuschner, 2006)
Skin Corrosion/Irritation Based on available data, the classification criteria as skin irritants are not met. However,
under conditions of substantial heat and sweating, high levels of dermal dust exposure may
cause mechanical/physical blocking of sweat glands in the absence of any intrinsic
substantial primary skin irritating potential of the substance and in consideration of the
poor solubility of ATO. The Committee for Risk Assessment (RAC) decided in July 2009
that a harmonized skin irritation classification was not supported (ECHA/PR/09/09, 2009).
ATO is not a corrosive agent.
Serious eye damage/irritation Based on available data, the classification criteria for eye irritation are not met (Leuschner,
2005).
Respiratory or skin
sensitization
Based on available data, the classification for skin sensitization (Chevalier, 2005; Moore,
G.E, 1994) and irritation to the respiratory system (Leuschner, 2006) are not met.
Germ Cell Mutagenicity ATO does not cause systemic mutagenicity in vivo after oral administration. Negative in
vivo results on chromosome aberrations and micronuclei were obtained in two different
species via oral application-mouse (Elliot et al., 1998) and rat (Whitwell, 2006), (Kirkland
et al., 2007). An in vivo UDS assay in rats was also negative (Elliot et al., 1998). Based
on available data, the classification criteria according to regulation (EC) 1272/2008 as
germ cell mutagen are not met.
Reproductive Toxicity Based on the available long-term toxicity studies in rodent (Omura et al, 2002) and the
relevant information on the toxicokinetic behavior in rats, it is concluded that the
classification criteria for reproductive toxicity are not met because of the lack of absorption
and systemic distribution, and a correspondingly negligible exposure of reproductive
organs in male and female mammalian species to ATO.
The reference Schroeder R.E. (2003) was identified as a key study for developmental
toxicity and will be used for classification and labeling. This study suggests that the
NOAEC for developmental toxicity is >6.3 mg ATO/m
3
. Thus, based on available data,
the classification criteria as developmental toxicant according to regulation (EC)
1272/2008 are not met.
STOT-single exposure Based on available data, the classification criteria as STOT-single exposure, oral, and
inhalation are not met since no reversible or irreversible adverse health effects were
observed immediately or delayed after exposure.

STOT-repeated exposure NOAECinhalation = 0.51 mg/m
3
(Newton et al, 1994)
NOAELoral = 1686 mg/kg/d (Hext et al, 1999)

The NOAEC was determined in a study with a high background incidence of lung
inflammation in controls, therefore there is considerable uncertainty regarding the
reliability of this numerical value. The NOAEC is based on impaired lung clearance
that was observed at 4.50 mg/m
3
.
Based on available data, the classification criteria as STOT-repeated exposure, oral is
not met since no reversible or irreversible adverse health effects were observed
immediately or delayed after exposure (NOAEL is above the guidance value).
Based on available data, the classification criteria as STOT-repeated exposure,
inhalation is not met since there is an absence of consistent identifiable toxic effects
other than the non-specific PSP overload, which is an adaptive response not triggering
a STOT classification.

Toxicity Endpoints Description of Effects
Carcinogenicity IARC classifies antimony trioxide as 2B possible carcinogenic to humans. ACGIH,
OSHA, and NTP do not classify antimony trioxide as a carcinogen. German MAK
Commission classified antimony trioxide as MAK-2 carcinogenic to humans.

ACGIH, OSHA, IARC, and NTP all classify arsenic as a carcinogen:
ACGIH: TLV-A1 confirmed human carcinogen.
OSHA: Ca
IARC-1 Carcinogenic to humans
NTP-K known to be a human carcinogen
German MAK Commission classified arsenic as MAK-1 confirmed human
carcinogen.

ACGIH and OSHA do not classify lead as a carcinogen.
IARC-2A Probably carcinogenic to humans.
NTP-R: Reasonably anticipated to be carcinogenic to humans.
German MAK-2 considered to be carcinogenic

(Di)antimony trioxide is classified as inhalation carcinogen category 2 (according to
Regulation (EC) 1272/2008).
Three chronic inhalation studies in rats are available for the carcinogenicity
assessment of (di)antimony trioxide (Watt, 1983; Groth et al., 1986a, Newton et al.,
1994). The exposure duration in all three animal studies is 12 months and thus all
studies deviate from the OECD guideline on chronic toxicity/carcinogenicity, which
prescribes an exposure period of 24 months for rats. The study by Newton et al.,
(1994) showed no (di)antimony trioxide related lung tumors, neither in males nor
females, at any dose level up to 4.5 mg/m
3
. The study shows that (di)antimony
trioxide reduced the pulmonary clearance rate in a dose-dependent manner. However,
it is well known that reduced lung clearance rate at chronic exposure of rats to poorly
soluble particles (PSPs) can result in pulmonary overload, subsequently followed by
an inflammatory response, epithelial cell hypertrophy and/or hyperplasia, and
squamous metaplasia. The persistence of these tissue responses over chronic time
periods can lead to the secondary development of lung tumors (Hext, 1994).
Due to the deviations from the OECD guidelines and the critical shortcoming in all
three studies, US NTP (National Toxicology Program) has embarked on a testing
program leading to a new, full 2-year bioassay; finalized end 2010 and reporting
expected in 2014-2015.
The overall expert judgment by TC NES was that the most likely mechanism for
carcinogenicity appears to be impaired lung clearance and particle overload followed
by an inflammatory response, fibrosis, and tumors. Consequently, (di)antimony
trioxide can be regarded as a threshold carcinogen and as a starting point for a
quantitative risk characterization, the NOAEC of 0.51 mg/m
3
derived for local
repeated dose toxicity is also used for carcinogenicity. However, in this context, it is
questionable whether effects caused by pulmonary overload in the rat are also relevant
for humans.

NOAEC: 0.51 mg/m
3
/ Target organ: respiratory: lung
Aspiration hazards ATO as an inorganic metal oxide is void of a low surface tension effect and as a solid
does have a very high viscosity, i.e., an aspiration hazard can safely be excluded.
Based on available data, the classification criteria are not met.

Aquatic microorganisms NOEC 2.55 mg Sb/L (EPAS, 2005)
Inhibition of nitrification EC50 27 mg Sb/L (EPAS, 2005)

Persistence and degradability: Whereas antimony formally meets the criterion for persistence based on the absence of any
degradation, this criterion is considered not to apply to inorganic elements. In addition, under conditions of a standard EUSES lake
and the median partition coefficient for suspended matter, antimony meets the criteria for rapid removal from the water column.

Bioaccumulative potential: Antimony does not meet the criteria for bioaccumulation: a BCF for aquatic organisms of 40 and a
BSAF of 1 for earthworms are derived and are all much lower than the threshold of 2,000 l/kg. Also, there is evidence to support
that antimony does not biomagnify in the food chain. Therefore, antimony is not considered bioaccumulative (B) or very
bioaccumulative (vB) based on the definitive criteria.

Mobility in soil: A log Kp of 2.07 has been determined for soil.

Results of PBT and vPvB assessment: The PBT and vPvB criteria of Annex XIII to the Regulation do not apply to inorganic
substances, such as antimony and its inorganic compounds. However, the available data have been compared to the criteria:
Antimony trioxide does not meet the criteria for PBT and vPvB. For (T): Chronic NOEC values are available for fish, invertebrates,
and algae. The lowest NOEC is 1.13 mg Sb/L for fish (Kimball, 1978). Antimony and antimony compounds do not meet any of the
toxicity criteria based on carcinogenicity, mutagenicity, or reprotoxicity (See Section 11) and there is no evidence of other chronic
concerns. Therefore, antimony is not considered toxic (T) based on the definitive criteria.

Antimony, and therefore (di)antimony trioxide is not PBT or vPvB.

Other adverse effects: (Di)antimony trioxide is not expected to contribute to ozone depletion, ozone formation, global warming, or
acidification.

Section 13 – Disposal Considerations
Waste treatment methods: Whatever cannot be saved for recovery or recycling should be managed in an appropriate and approved
waste disposal facility. If the percentage of ATO in waste is greater than 1%, then the waste must be treated as hazardous under
Directive 91/689/EEC. If the concentration is below 1%, then ATO-containing waste shall be handled as non-hazardous waste. All
waste should be removed by a licensed waste removal company, incinerated, or recycled. If only the total antimony concentration in
waste is known, then waste with greater than 1% antimony should be treated as hazardous under Directive 91/689/EEC. Processing,
use, or contamination of this product may change the waste management options. State and local disposal regulations may differ
from federal disposal regulations. Dispose of container and unused contents following federal, state, and local requirements. The
used packaging is only meant for packing this product. After usage, empty the packaging completely.

Suitable disposal of hazardous waste for manufacturing and industrial use: Keep separate and dispose of to either
-Hazardous waste incineration operated according to Council Directive 2008/98/EC on waste, Directive 2000/76/EC on the
incineration of waste, and the Reference Document on the Best Available Techniques for Waste Incineration of August 2006.
-Hazardous landfill operated under Directive 1999/31/EC.
Suitable disposal of non-hazardous waste for manufacturing and industrial use: Disposal of wastes is possible via incineration
(operated according to Directive 2000/76/EC on the incineration of waste) or landfilling (operated according to Reference Document
on the Best Available Techniques for Waste Industries of August 2006 and Council Directive 1999/31/EC and Council Decision 19
December 2002).
Suitable disposal of waste for professional use: Waste from end-of-life articles can be disposed of as municipal waste, except
when they are separately regulated, like electronic devices, batteries, vehicles, etc. Disposal of wastes is possible via incineration
(operated according to Directive 2000/76/EC on the incineration of waste) or landfilling (operated according to Reference Document
on the Best Available Techniques for Waste Industries of August 2006 and Council Directive 1999/31/EC and Council Decision 19
