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
13.Disposal considerations
13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
