Section 11 Toxicological Information



CAS# 7439-97-6: OV4550000


Not available.



CAS# 7439-97-6:

IARC: IARC Group 3 not classifiable.

Epidemiology: Intraperitoneal, rat: TOL0 = 400/mg/kg/14D-I (tumorigenic equivocal tumorigenic agent by RTECS criteria tumors at site of application)

Teratogenicity: Inhalation, rat; TCLo = mg/m3/24H (female 1-20 day(s) after conception) Effects on Embryo or Fetus fetotoxicity (except death, e.g., stunted fetus).

Reproductive Effects: Inhalation, rat: TCLo = 890 ng/m3/24H (male 16 week(s) pre-mating) Paternal Effects spermatogenesis (incl. genetic material, sperm morphology, motility, and count).; inhalation, rat: TCLo = 7440 ng/m3/24H (male 16 week(s) pre-mating) Fertility post-implantation mortality (e.g. dead and/or resorted implants per total number of implants).

Neurotoxicity: The brain is the critical organ in humans for chronic vapor exposure; in severe cases, spontaneous degeneration of the brain cortex can occur as a late sequel to past exposure.


Mutagenicity: Cytogenetic Analysis: Unreported, man = 150 ug/m3.

Other Studies: No Information available.


Section 12 Ecological Information


Ecotoxicity: Fish: Rainbow trout: LC50 = 0.16-0.90 mg/L; 96 Hr: Unspecified Fish: Bluegill/Sunfish; LC50=0.15-0.90mg/L; 96 hr: Unspecified Fish: Channel catfish; LC50=0.35 mg/L; 96hr;Unspecified Water flee Daphnia: EC50 = 0.01 mg/L:48 Hr; Unspecified in aquatic systems, mercury appears to blind to dissolved matter or fine particulates, while the transport of mercury bound to dust particles in the atmosphere or bed sediment particles in rivers and lakes is generally less substantial. The conversion, in aquatic environments, of inorganic mercury cmpd to methyl mercury implies that recycling of mercury from sediment to water to air and back could be a rapid process.

Environmental: Mercury bioaccumulates and concentrates in food chain (concentration may be as much as 10,000 times that of water).  Bioconcentration factors of 63,000 for freshwater fish and 10,000 for salt water fish have been found.  Much of the mercury deposited on land, appears to revaporize within a day or two, at least in areas substantially heated by sunlight.

Physical: All forms of mercury (Hg) (metal, vapor, inorganic, or organic) are converted to methyl mercury.

Other: No information available.



                      Section 13- Disposal Considerations
