12.2 Persistence and degradability

AEROBIC: The theoretical BOD of methyl isobutyl ketone (5 ppm) in seawater was measured as 27.6% and 30.6% over a 5 day incubation period(1). The theoretical BOD of methyl isobutyl ketone in freshwaters seeded with settled domestic sewage was 56%, 66%, 69% and 69%, over 5, 10, 15 and 20 day incubation periods(2). The theoretical BOD of methyl isobutyl ketone in synthetic seeded seawaters with settled domestic sewage was 15%, 46%, 50% and 53%, over 5, 10, 15 and 20 day incubation periods(2). The theoretical BOD of a 100 mg/L sample of methyl isobutyl ketone in an activated sludge inoculum was 84% over a 2 week incubation period(3). Methyl isobutyl ketone was degraded 78-84% with a degradation rate of 0.24 1/hr in experiments using activated sludge inoculum, 100 mg/L of methyl isobutyl ketone, 30 mg/L biomass and a temperature of 28°C for 28 days(4). Methyl isobutyl ketone had influent concns of 8100, 8100 and 190 ug/L and effluent concns of 27.5, 40.5 and <10 ug/L using an activated sludge with a daily mass loading of COD/bacterial mass ratios of 0.1, 0.36 and 0.48, respectively(5). Methyl isobutyl ketone was degraded from 855 ug/L to 143 ug/L in 12 hours and from 3385 ug/L to 1098 ug/L in 8 hours using activated sludge that was acclimated for 3 weeks(6). In a wastewater stream, a BOD of 2.06 g of oxygen/g and a COD of 2.16 g of oxygen/g for methyl isobutyl ketone were found(7).

12.3 Bioaccumulative potential

An estimated BCF of 2 was calculated in fish for methyl isobutyl ketone(SRC), using a log Kow of 1.31(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 methyl isobutyl ketone is estimated as 120(SRC), using a log Kow of 1.31(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that methyl isobutyl ketone is expected to have high mobility in soil.
