    SECTION 12: Ecological information

    12.1 Toxicity

    • Toxicity to fish: LL50 - Oncorhynchus mykiss (previous name: Salmo gairdneri) - 34.05 mg/L - 96 h.
    • Toxicity to daphnia and other aquatic invertebrates: EL50 - Daphnia magna - 59.44 mg/L - 48 h.
    • Toxicity to algae: EL50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 25.12 mg/L - 72 h.
    • Toxicity to microorganisms: NOEL - Tetrahymena pyriformis - 29.28 mg/L - 48 h.

    12.2 Persistence and degradability

    AEROBIC: Organisms isolated from groundwater contaminated by a gasoline spill were found to grow when inoculated with pure samples of isopentane; however, no biodegradation of isopentane was observed when a mixed culture of these organisms was inoculated with gasoline(1). A mixture containing isopentane, pentane, cyclopentane, 2,3-dimethylbutane, 2-methylpentane, 3-methylpentane, and cyclohexane, showed little degradation over the course of 30 days in a sediment/groundwater obtained from a contaminated jet fuel site in Oscoda, MI(2). Following a 6.1 day lag period, isopentane was completely degraded using an activated sludge over the course of a 20 day incubation period under aerobic conditions(3). The half-life of a mixture containing isopentane, pentane, and cyclopentane in seawater was 2.4 days(4).

    12.3 Bioaccumulative potential

    An estimated BCF of 70 was calculated in fish for isopentane(SRC), using a water solubility of 48 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

    12.4 Mobility in soil

    The Koc of isopentane is estimated as 520(SRC), using a water solubility of 48 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isopentane is expected to have low mobility in soil(SRC).

    12.5 Other adverse effects

    no data available

    SECTION 13: Disposal considerations

    13.1 Disposal methods

    Product
