    Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)

    • Toxicity to fish: LC50 Pimephales promelas (fathead minnows) 4.48 g/l/96 hr (95% confidence limit 4.10-4.88 g/l); age 30 days old, water hardness 47.0 mg/l (CaCO3), temp 27.7°C, pH 7.40, dissolved oxygen 5.4 mg/l, alkalinity 43.0 mg/l (CaCO3), tank vol: 1.0 l, additions: 36 vol/day (flow-through bioassay)
    • 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: n-Propanol is readily degraded in laboratory tests using activated sludges, sewage seeds, and wastewater inocula(1-4). In 1 day test using 500 mg/l n-propanol and activated sludge at 20°C, a 37% theoretical oxygen demand (ThOD) was obtained(1). Biodegradation of 3, 7, and 10 mg/l with filtered sewage seed in fresh water resulted in a 64% ThOD in 5 days and 75% ThOD in 20 days(2). n-Propanol was 99% removed using acclimated activated sludge at 20°C (71 mg COD/g-hr rate)(3). Biodegradation of n-propanol in fresh water, using a domestic and synthetic waste water seed, resulted in a 93% ThOD and 97% ThOD (in 5 day tests), respectively(4). Biodegradation of 3, 7, and 10 mg/l with filtered sewage seed in salt water resulted in a 43% ThOD in 5 days and 73% ThOD in 20 days(2).

    12.3 Bioaccumulative potential

    An estimated BCF of 3 was calculated for n-propanol(SRC), using a log Kow of 0.25(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

    12.4 Mobility in soil

    The Koc of n-propanol is estimated as 33(SRC), using a measured log Kow of 0.25(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that n-propanol is expected to have very high mobility in soil(SRC).

    12.5 Other adverse effects

    no data available

    13.Disposal considerations

    13.1 Disposal methods

    Product
