Persistence and degradability
AEROBIC: The 2,4-D isopropyl ester is degraded in a laboratory test by activated sewage acclimated to 2,4-D(1). 2,4-D isopropyl ester is degraded at half the rate of the parent acid which is rapidly degraded(1). In another study, in which 2,4-D isopropyl ester was incubated with domestic sewage microorganisms, 2,4-D isopropyl ester was hydrolyzed and the acid was later decomposed biologically(2). The lag period being 7 days after which the isopropyl alcohol was 98.5% oxidized in 2 days(2). These results are consistent with microbial hydrolysis after a 7 day acclimation period(2).
Bioaccumulative potential
According to a classification scheme(1), an estimated BCF of 80(SRC), from its water solubility(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). However, like 2,4-D butyl ester, 2,4-D isopropyl ester may also be readily metabolized in fish and therefore should not bioconcentrate(4).
Mobility in soil
The Koc of 2,4-D isopropyl ester is estimated as 600(SRC), using a water solubility of 37.3 mg/l(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2,4-D isopropyl ester is expected to have low mobility in soil(SRC). 2,4-D isopropyl ester is adsorbed slightly by clay minerals with the adsorption to bentonite > illite > kaolinite(4). Large amounts of bentonite, illite and kaolinite, namely 6.89, 11.79 and 37.59 grams respectively, would be required to reduce the concentration of 2,4-D isopropyl ester in water from 3 mg/l to 2 mg/l(4).
Other adverse effects

SECTION 13: Disposal considerations
Disposal methods
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.
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.
