Acute Tox. 3 (25.3%)
소화Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
응급 처치EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
비화재 누출 대응SMALL SPILLS AND LEAKAGE: If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
처리 방법SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

It is concluded that under the conditions of this bioassay, ethyl tellurac was not carcinogenic for F344 rats or B6C3Fl mice of either sex. The incidence of mesotheliomas in dosed male rats and the incidence of adenomas of the lacrimal (harderian) gland of the eye in dosed mice of either sex provided evidence which was suggestive but under the conditions of the bioassay insufficient to establish the carcinogenicity of ethyl tellurac in these animals. ... Levels of Evidence of Carcinogenicity: Male Rats: EquivocalFemale Rats: NegativeMale Mice: EquivocalFemale Mice: Equivocal.Seven dithiocarbamates and 3 acetates were tested for teratogenicity and lethality in 3-day chicken embryos. These included cadmium diethyldithiocarbamate (CdDE), zinc diethyldithiocarbamate (ZnDE), zinc ethylphenyldithiocarbamate (ZnEP), zinc dibutyldithiocarbamate (ZnDB), copper dimethyldithiocarbamate (CuDM), tellurium diethyldithiocarbamate (TeDE) And piperidine pentamethylenedithiocarbamate (PPM), cadmium acetate (CdAC), copper-(II) acetate (CuAC) and zinc acetate (ZnAC). The parameters measured were early deaths, recorded within 2 days of injection, late deaths of malformed embryos, late deaths of nonmalformed embryos and malformed survivors. The order of embryotoxicity decreased as follows: CdAC > CdDE > ZnDE \ ZnEP \ ZnDB > CuDM > TeDE > CuAC > PPM > ZnAC. The only exception to this order was the relatively weak teratogenicity of the metal acetates as compared to dithiocarbamates.
Evidence for CarcinogenicityNo data are available in humans. Inadequate evidence of carcinogenicity in animals. OVERALL EVALUATION: Group 3: The agent is not classifiable as to its carcinogenicity to humans.

National Toxicology Program StudiesA bioassay of technical grade ethyl tellurac for possible carcinogenicity was conducted by admin the preparation in feed to F344 rats and B6C3Fl mice. Groups of 50 rats of each sex were admin ethyl tellurac at one of two doses, either 300 or 600 ppm for the males and either 150 or 300 ppm for the females, for 105 wk. Matched controls consisted of 20 untreated rats of each sex. All surviving rats were /sacrificed/ at 105 wk. Groups of 50 mice of each sex were admin ethyl tellurac at one of two doses, initially either 2,500 or 5,000 ppm. Due to signs of toxicity in the dosed animals, these doses were reduced to 500 and 2,000 ppm, respectively, starting at wk 41 for the males and at wk 38 for the females. The reduced doses were maintained for 66 wk for the malesfor the females, the reduced doses were raised after 3 wk to 2,000 and 5,000 ppm, respectively, and maintained at these levels for 66 wk. The time-weighted average doses for the males were either 1,255 or 3,132 ppmfor the females, either 2,132 or 4,915 ppm. Matched controls consisted of 20 untreated mice of each sex. All surviving mice were /sacrificed/ at 106 weeks. ... Survival of the rats and the mice was not affected by the chemical, and sufficient numbers of all groups were at risk for the development of late appearing tumors. ... It is concluded that under the conditions of this bioassay, ethyl tellurac was not carcinogenic for F344 rats or B6C3Fl mice of either sex. The incidence of mesotheliomas in dosed male rats and the incidence of adenomas of the lacrimal (harderian) gland of the eye in dosed mice of either sex provided evidence which was suggestive but under the conditions of the bioassay insufficient to establish the carcinogenicity of ethyl tellurac in these animals. ...
