12.2 Persistence and degradability
AEROBIC: In a screening test designed to simulate biodegradation in a polluted river, the 5 day theoretical BOD for 2-pentanone was 43%(1). A 1.8% theoretical BOD was measured for 2-pentanone in an activated sludge inoculum over a 24 hour incubation period(2). 2-Pentanone was biodegraded by microorganisms isolated from soil and sludge(3).
12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for 2-pentanone(SRC), using a log Kow of 0.91(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 2-pentanone is estimated as 75(SRC), using a log Kow of 0.91(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-pentanone is expected to have high 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.
