Persistence and degradability
AEROBIC: 2,5-Dinitrotoluene was not mineralized in water from a pond and from Waconda Bay; however, 2,5-dinitrotoluene was co-metabolized when 500 ppm of yeast extract were added to the water from these two sources(1). The rate of degradation with added yeast extract in Searsville Pond water was 2.3X10+10 mL/cell-hour, and in Waconda Bay water was 12X10+10 mL/cell-hour(1). Analogous compound 2,4-dinitrotoluene was used as the sole carbon source and mineralized in natural surface water that had been acclimated to 120 ppm 2,4-dinitrotoluene; after a 2-3 day lag period, >90% of 10 ppm 2,4-dinitrotoluene was transformed in aerated water after 6 days of incubation(2). Mixed dinitrotoluene isomers, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test that suggests the compound is not readily biodegradable(3).
Bioaccumulative potential
An estimated BCF of 13 was calculated for 2,5-dinitrotoluene(SRC), using an estimated log Kow of 2.18(1) and a regression-derived equation(1). The BCF for dinitrotoluene (mixed isomers) has been measured to be low (BCF values of 0.6 to 21.2) in carp (Carprinus carpio)(2). According to a classification scheme(2), these BCF values suggest the potential for bioconcentration in aquatic organisms is low.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2,5-dinitrotoluene can be estimated to be 575(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,5-dinitrotoluene is expected to have medium mobility in soil.
Other adverse effects
no data available
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.
