Methylene Chloride:
TOXICITY: LC50 310 mg/L 96 hrs (static) Fathead Minnow; LC50 220 mg/L 96 hrs (static) Bluegill Sunfish;
LC50 256 mg/L 96 hrs Mysid Shrimp
PERSISTENCE AND DEGRADABILITY: If released to air, a vapor pressure of 435 mm Hg at 25 deg C
indicates dichloromethane will exist solely as a vapor in the ambient atmosphere. This material released to the
atmosphere will degrade by reaction with hydroxyl radicals with a half-life of several months. It is not subject to
direct photooxidation. On land is expected to evaporate rapidly into the atmosphere due to its high vapor
pressure. it is poorly adsorbed to soil and can leach into the groundwater. Calculated Adsorption Coefficient
(log KOC) is 1. This material is subject to rapid evaporation, with estimated evaporative half-lives ranging from
3 to 5.6 hours under moderate mixing conditions. This material has a negligible rate of hydrolysis.
Biodegredation may occur in groundwater, but will be very slow compared with evaporation.
BIOACCUMULATIVE POTENTIAL: Bioconcentration potential in aquatic organisms is low with BCF of 2.
MOBILITY IN SOIL: If released to soil, dichloromethane is expected to have very high mobility based upon an
estimated Koc of 24.
OTHER ADVERSE EFFECTS: No data.
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. Biodegradation is expected to occur in natural waters since methanol is degraded quickly in soils
and was biodegraded rapidly in various aqueous screening tests using sewage seed or activated sludge.
Hydrolysis of methanol and photolysis in sunlit surface waters are not expected since methanol lacks functional
groups that are susceptible to hydrolysis or photolysis under environmental conditions.
BIOACCUMULATIVE POTENTIAL: BCF values of less than 10, measured in fish suggests bioconcentration in
aquatic organisms is low.
MOBILITY IN SOIL: If released to soil, methanol is expected to have very high mobility based upon an
estimated Koc of 1.
Stoddard Solvent:
TOXICITY: This mixture contains components that are potentially toxic to freshwater and saltwater ecosystems.
This material may be harmful to aquatic organisms and may cause long term adverse effects in the aquatic
