SECTION 3: Composition/information on ingredients
Substance
- Chemical name: Phenylmercury acetate
- Common names and synonyms: Phenylmercury acetate
- CAS number: 62-38-4
- EC number: 200-532-5
- Concentration: 100%
SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Half-upright position. Refer immediately for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower for at least 15 minutes. Refer immediately for medical attention .
Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.
Most important symptoms/effects, acute and delayed
Extremely toxic. The probable oral lethal dose for humans is 5-50 mg/kg, between 7 drops and 1 teaspoonful for a 70 kg (150 lb.) person. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Although the use of BAL is indicated in severe inorganic mercury poisoning, the effectiveness of BAL in organic and elemental mercury poisoning is highly questionable. There are survivors of severe elemental mercury poisoning who have been treated only with supportive care. Dimercaprol is ineffective in reversing chronic organic neurologic effects but should be administered in acute ingestions of aryl organic mercury compounds (eg, phenylmercuric acetate, which is converted to inorganic mercury in the body).
SECTION 5: Firefighting measures
Suitable extinguishing media
If material is in solution with organic solvent, treat fire according to the solvent characteristics, in addition to the mercuric hazard. Unless otherwise indicated, use water spray, dry chemical, "alcohol resistant" foam, or carbon dioxide. Water may be ineffective.
Specific hazards arising from the chemical
Fire may produce irritating or poisonous gases. When heated to decomposition, very toxic mercuric fumes may be given off. Phenylmercuric ion is incompatible with halides, with which precipitates are formed. (EPA, 1998)
Special protective actions for fire-fighters
Use water spray, powder, foam, carbon dioxide.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Then store and dispose of according to local regulations.

- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
Soil and aquatic microorganism: Phenlymercuric acetate is quickly degraded, with diphenylmercury as one of the major metabolic products.
Bioaccumulative potential
Phenylmercuric acetate is not expected to bioconcentrate in aquatic organisms as it dissociates rapidly in water forming phenylmercuric cation. (SRC)
Mobility in soil
The Koc of phenylmercuric acetate is estimated as 60(SRC), using a log Kow of 0.71(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that phenylmercuric acetate is expected to have a high mobility in soil. However, phenylmercuric acetate is expected to dissociate in moist soils to the cation(SRC). Cations generally adsorb to organic matter and clay more strongly than their neutral counterparts, suggesting that the mobility may be much lower in some soils(SRC). In a river study, it was found that the phenymercuric cation sorbed strongly to particles and humic material in the water column(4).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
