  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: When seeded with a soil inoculum, 1,1'-methylenebisbenzene underwent extensive degradation in 40 days, following a 30 day lag(1). 1,1'-Methylenebisbenzene was completely degraded within 5 days in a river die-away test(2); the study found that, in general, 1,1'-methylenebisbenzene compunds having an unsubstituted phenyl ring undergo rapid primary biodegradation(2). 1,1'-Methylenebisbenzene is degraded by microorganisms isolated from sewage, water, soil, and leaves(3-5). Three metabolic pathways have been identified leading to the initial metabolic product 1,1,1',1'-tetraphenyldimethyl ether, phenylacetic acid, and benzhydrol(3). 1,1'-Methylenebisbenzene, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(6).

12.3 Bioaccumulative potential

Using catfish which were exposed over an 8-week period to 1,1'-methylenebisbenzene concentrations of 0.01 mg/L and 0.1 mg/L, 1,1'-methylenebisbenzene BCF values were measured that ranged from 452 to 1190(1). According to a classification scheme(3), this BCF range suggests the potential for bioconcentration in aquatic organisms is high to very high(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 1,1'-methylenebisbenzene can be estimated to be 9160(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1,1'-methylenebisbenzene is expected to be immobile in soil.

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

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.

Contaminated packaging

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.

Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Provide ventilation.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.
