Persistence and degradability

AEROBIC: The biodegradability of 2,6-dinitrotoluene was tested in a static screening test using flasks that contained either 5 or 10 mg/L 2,6-dinitrotoluene, 5 mg/L yeast extract and settled domestic sewage as the inoculum. Subcultures were done every 7 days. The percent biodegradation by the original culture and first, second and third subcultures at an initial 2,6-dinitrotoluene concentration of 10 mg/L was: 57, 49, 35 and 13%, respectively(1). 2,6-Dinitrotoluene at an initial concentration of 10 ug/ml (10 mg/L) did not significantly degrade after 28 days incubation with raw municipal sewage(2). In another study, 2,6-dinitrotoluene inhibited biodegradation of municipal sewage at concentrations above 50 mg/L(3). In the same study, industrial seed degraded 50 mg/L 2,6-dinitrotoluene to 25 mg/L in 2 days, but after 7 days, 2,6-dinitrotoluene concentration remained at 25 mg/L. 2,6-Dinitrotoluene was easy to degrade according to results obtained by the "cultivation method" in which 98-100% and 83-100% degradation occurred in 3 days in river water and coastal sea water in Japan, respectively(7). 2,6-Dinitrotoluene was easily degraded by microorganisms in seawater, although the 2,6-isomer was the least readily degraded than all other dinitrotoluene isomers(4). This is consistent with the observation that the rate of reduction of nitro compound increases with increasing electron withdrawing power of groups in the para position(6). Degradation in river water was generally higher than in seawater(5). No degradation rates were given. The average percent biodegradation in eleven test runs of a pilot activated sludge plant was 57%(8).

Bioaccumulative potential

An estimated BCF of 11 was calculated for 2,6-dinitrotoluene(SRC), using a log Kow of 2.10(1) and a regression-derived equation(2). The BCF for dinitrotoluene (mixed isomers) has been measured to be low (BCF values of 0.6 to 21.2) in carp (Carprinus carpio)(3). According to a classification scheme(4), these BCF values suggest the potential for bioconcentration in aquatic organisms is low. An experimental log BCF of 2.44 (BCF of 275) (fat basis) was determined for 2,6-dinitrotoluene in the guppy (Poecilia reticulata) in a 3-day static test(5).

Mobility in soil

The Freundlich adsorption constant (exponent 1/n) for 2,6-dinitrotoluene in a Mississippi sandy loam soil (pH 5.6, organic carbon 0.94%) and a Texas sandy silt loam soil (pH 8.1, organic carbon 3.25%) was 0.014 (0.68) and 0.005 (0.61), respectively(1) which correspond to Koc values of 72 and 19, respectively(SRC). In a loamy sand soil containing an organic matter content of 8.5 g/kg, 2,6-dinitrotoluene had measured Kd adsorption coefficient 0.97 cu cm/g(2) that correspond to a Koc 197(SRC). According to a classification scheme(3), these Koc values indicate that 2,6-dinitrotoluene is expected to have very high to moderate mobility in soil. Field monitoring at a munition factory site in Melbourne Australia found that 2,6-dinitrotoluene migrated large distances in the subsurface soils(4). Leaching of 2,6-dinitrotoluene has been observed in soil column transport studies(5).

SECTION 13: Disposal considerations

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.
