SAFETY DATA SHEET
mg/L in most sensitive species tested).
LC50, rainbow trout, 96 hr, 1,700 mg/L
LC50, water flea, 835 mg/L
LC50, bacteria, >1,000 mg/L
Persistence and Degradability: Material is readily biodegradable.
Bioaccumulative Potential: Bioconcentration potential is low (BCF <100 or LOG POW <3).
Mobility in Soil: Potential for mobility in soil is high (KOC between 50 and 150).
Other Adverse Effects: No data.

Methyl Ethyl Ketone:
Toxicity:
LC50 Daphnia magna (water flea) <520 mg/L 48-hr
LC50 Lepomis macrochirus (bluegill) 5,640-1,690 mg/L 24 to 96-hr
Has shown low toxicity to fish and aquatic invertebrates.
At above 100 ppm it may inhibit the growth of blue-green algae but such concentrations are unlikely to be
reached except for short periods following accidental discharge.
Persistance and Degradability: MEK is readily biodegradable.
Bioaccumulative Potential: Data suggests that MEK is unlikely to concentrate in aquatic species.
Mobility in Soil: MEK is expected to have very high mobility based upon Koc values of 29 and 34 obtained in
silt loams.

Ethyl Acetate:
Toxicity:
LC50 HETEROPNEUSTES FOSSILIS (COMMON INDIAN CATFISH) 212.5 PPM/96 HR /
LC50 Pimephales promelas (fathead minnow) 230 mg/l/96 hr
EC50 Pimephales promelas (fathead minnow) 220 mg/l/96 hr
Persistance and Degradability: Biodegradation is expected to be an important process in both soil and water.
Bioaccumulative Potential: If released into water, ethyl acetate is not expected to adsorb to suspended solids and
sediment in water based on the estimated Koc. An estimated BCF of 3.2 suggests the potential for
bioconcentration in aquatic organisms is low.
Mobility in Soil: Expected to have high mobility based upon an estimated Koc of 59.

Methanol:
TOXICITY: Methanol is of low toxicity to aquatic organisms. LC50 Pimephales promelas (fathead minnows)
29.4 g/L/96 hr, (28-29 days old), confidence limit= 28.5-30.4; Test conditions: Water temp= 25 deg C, dissolved
oxygen= 7.3 mg/L, water hardness= 43.5 mg/l calcium carbonate, alkalinity= 46.6 calcium carbonate, tank
volume= 6.3 L, additions= 5.71 V/D, pH= 7.66 (0.03).
PERSISTENCE AND DEGRADABILITY: If released to the atmosphere, a vapor pressure of 127 mm Hg at 25
deg C indicates that methanol will exist solely in the vapor phase. Vapor phase methanol is degraded in the
atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is
estimated to be 17 days. Volatilization from moist soil surfaces is expected to be an important fate process based
upon a Henry's Law constant of 4.55X10-6 atm-cu m/mole. Methanol may also volatilize from dry soils based
upon it vapor pressure. Biodegradation of methanol in soils is expected to occur rapidly based on half-lives in a
sandy silt loam from Texas and a sandy loam from Mississippi of 1 and 3.2 days, respectively. If released into
water, methanol is not expected to adsorb to suspended solids and sediment based upon the estimated Koc.
Volatilization from water surfaces is expected to be an important fate process based upon this compound's Henry's
Law constant. Estimated volatilization half-lives for a model river and model lake are 3 and 35 days, respectively.
