HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification	Classification year (FY)	GHS Classification Guidance for the Japanese Government
1	Acute toxicity (Oral)	Category 2	Danger	H300	P301+P310 P264 P270 P321 P330 P405 P501	Based on a LD50 value of 22 mg/kg (HSDB (2005)) for rats, the substance was classified into Category 2.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）

1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
2	Skin corrosion/irritation	Category 1	Danger	H314	P301+P330+P331 P303+P361+P353 P305+P351+P338 P304+P340 P260 P264 P280 P310 P321 P363 P405 P501	In a patch test in which a 0.1% solution of the substance was applied to humans for 24-hour, a vesicular rash (grade of 4+) was observed, and this substance was judged to be a primary irritant (RTECS (2008): Archives of Dermatology 106, 129 (1972)). Redness, pain, blurred vision and severe deep burns are reported following exposure to this substance (ICSC (J) (2005)). In EU classification, the substance is classified into R34 (EU-Annex I (access on May 2009)). Based on the data, the substance was classified into Category 1.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
3	Serious eye damage/eye irritation	Category 1	Danger	H318	P305+P351+P338 P280 P310	As information in documents in List 3, redness, pain, blurred vision and severe deep burns are reported following exposure to the substance (ICSC (J) (2005)). In a rabbit standard Draize test, "severe" result is reported (RTECS (2008)). The substance is classified into Category 1 and skin corrosive substance. Based on these data, the substance was classified into Category 1.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Skin sensitization	Category 1	Warning	H317	P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501	In a guinea pig Buhler test, positive results were obtained in 14/18 (77.8%) animals (DFGOT vol. 15 (2001)). Based on the data, the substance was classified into Category 1. In humans, patch tests were carried out with a 0.01% solution of the substance and positive results were obtained in 29 (1.4%) of the 2030 patients tested (21 of these were only weakly positive) (DFGOT vol. 15 (2001)). In other patch tests with 0.01% and 0.05% solutions, positive rates were 1.4% and 5.8%, respectively (DFGOT vol. 15 (2001)). The substance is classified as Sh in DFG.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Although there is a report that an increased incidence of SCE was found in the lymphocytes of 38 Argentinean children who were exposed to phenylmercuric acetate used as a disinfectant in nappies, but 9 months after the end of exposure, the incidence of SCE was no longer increased (in vivo somatic cell mutagenicity) (DFGOT vol. 15 (2001)), the details are unknown. Classification was not possible due to lack of sufficient data from in vivo mutagenicity tests. As relevant information, from in vitro mutagenicity tests, there is a report of a negative Ames test (NTP DB (access on May 2009)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
6	Carcinogenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. In a 103-week oral (in drinking water) test in male rats, the incidence of tumors in the high dose group was significantly increased in comparison to the control group. The increase in number of incidences were a result of an increase in the incidence of renal cell adenomas (DFGOT vol. 15 (2001)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	It is reported that acetoxyphenylmercury is a strong teratogen for more than one animal species as it induces disorder of the central nervous system and eye, and anury in mice, multiple malformation in rats and rabbits, and exencephaly in hamsters (Birth Defects (3rd, 2000)). When hamsters, rats and mice were administered by stomach tube from days 5 - 12 of gestation, embryotoxic effects induced were resorptions, dead fetuses, and retardation of development. Teratogenic effects were diminished cranial ossification, edemata of body, hematomas and open eyes (HSDB (2009)). Although there are reports of teratogenicity in more than one animal species, the data are in assessment documents in List 2, therefore the substance was classified into Category 2.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	There is a report that a single dose exposure to rats caused hematological effects such as morphological alterations in erythrocytes and inhibited platelet factor (HSDB (2009)). However, since required information about test method and results are not reported, classification was not possible.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
9	Specific target organ toxicity - Repeated exposure	Category 1 (kidney, nervous system)	Danger	H372	P260 P264 P270 P314 P501	In a 2-year oral test in rats, nephropathy was observed at dietary phenylmercuric acetate concentrations of 0.042 mg/kg/day and higher. Renal lesions were observed at 0.21 mg/kg/day and higher concentrations in both sexes (IRIS (2002)). In rats given phenylmercuric acetate at concentrations of 0.71 - 7.1 mg/kg/day in drinking water for 2-year, pigment deposits were found in the renal cortex and the incidence and severity of age-related chronic nephrosis were increased. The authors suggested that the mechanism of the carcinogenicity could involve the effects of the substance (DFGOT vol. 15 (2001)). Since these renal lesions were noted at dose levels within the guidance value range for Category 1, the substance was classified into Category 1 (kidney). A 39-year-old farmer who had treated seeds with phenylmercuric acetate for 6 – 7 seasons died within several months of developing severe neurological toxicity (ATSDR (1999)). A 39-year-old farmer exposed while dusting oat seeds with the substance, excreted large amounts of mercury in the urine, died of an apparently progressive neurologic disease resembling amylotrophic lateral sclerosis (HSDB (2009)). Based on these case reports of neuropathy where the involvement of the exposure is suggested, the substance was classified into Category 1 (nervous system). There is another exposure case report which describes a swollen mouth, reddened and tender gums, a thin blue line at the gums and carious teeth (ATSDR (1999)), however, these symptoms can not affect the alimentary system severely, therefore the data was not used as the basis of classification. As for effects on the respiratory system, there is a case report where dyspnea and respiratory depression were observed and an autopsy revealed purulent bronchopneumonia. However, it is unclear whether the respiratory effects were direct effects of the phenylmercuric acetate or secondary to the severe neurotoxicity also seen in this subject (ATSDR (1999)). Based on this uncertainty this respiratory system data was not used as the basis of classification.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
