Organs that may be effected by exposure to large concentrations or intentional prolonged abuse of toluene
include, but not limited to: central and peripheral nervous system, vision, hearing, liver, heart, kidneys, blood.
Acute and Chronic Effects

SECTION 12 ................................................. ECOLOGICAL INFORMATION.......................................................................
DMDCS 75-78-5
Ecotoxicity: WGK 1 Aquatic toxicity range Tlm 96-100 ppm. Dimethyldichlorosilane is not expected to last long
enough in the environment to bioaccumulate.
Environmental Fate: Dimethyldichlorosilane hydrolyzes in water to release hydrochloric acid. Rapid volatilization
would be expected from soil. Dimethyldichlorosilane would be expected to hydrolyze in the water
droplets in the atmosphere.
Toluene 108-88-3
Ecotoxicity: This material is expected to be toxic to aquatic life. The LC50/96H values for fish are between 10 and
100 mg/L: Bluegill LD50 17mg/L/24H; Shrimp LC50 4.3 ppm/96H; Fathead minnow LC50 36.2 mg/L/96H;
Sunfish (fresh water) TLm 1180 mg/L/96H.
Environmental Fate: Toluene evaporates from soil and water to a moderate extent and can leach into
groundwater from soil. In soil, water, and air, it is expected to biodegrade to a moderate extent. It has a
log octanol-water partition coefficient of less than 3.0. Bioconcentration factor = 13.2 (eels).
Glas-Treet
Ecotoxicity: No data available on mixture. See components.
Environmental Fate: No data available on mixture. See components.
Standard Chemical Precautions
Keep out of water, air, and soil.
