Persistence and degradability
2,4-D dimethylamine is rapidly degraded by aquatic microorganisms in activated sewage at about the same rate as the free acid(1). The same study showed that biodegradation is sensitive to temperature, increasing by an order of magnitude for 2,4-D as the temperature is increased from 10 to 25 deg C(1). A half-life of 3.9 days was obtained for an unspecified amine salt of 2,4-D in a river-dieaway study(5). Half-lives obtained from other studies are: 10-11 days in plastic pools containing fish and hydrosoil, 6.6 days in Ft. Cobb Reservoir, 4.2 days in outdoor, artificial pool, 2.2 and 3.2 days in Louisiana ponds, 0.5-0.8 days in Okananagan Lake, British Columbia, 2.5-6.2 days for Melton Hill Reservoir in the Tennessee Valley Authority system, <1 day in Lake Seminole, and 2.5-6.2 days for Banks Lake, WA(5). While processes other than biodegradation may be contributing to the degradation in these studies, biodegradation is probably the key process(5). When the amine salts were sprayed onto field plots in Nova Scotia at 5.6, 11.2, and 22.4 kg/ha acid equivalent and soil cores sampled after 13 hr and 14, 28, 56, 70, 265, and 385 days, rapid decomposition of the 2,4-D was observed in the 14-42 day period following application and <5% remained at the end of 70 days(2). Highest 2,4-D concentrations were observed 14 days posttreatment(2). It is believed that the formulation was absorbed by the grass and later washed into the soil by rain and dew(2). A more recent field study looked into the persistence of 2,4-D applied as the dimethylamine salt in field plots in southern and northern Ontario as well as two forested areas in northern Ontario(3). In the two agricultural plots, 50% loss in the upper 10 cm of the soil profile occurred in 4 and 6 days(3). In the two forest plots characterized by sandy clay loam and fine sand soils, the half-lives were 7 and 23 days(2). The soil in the second case was characterized by lower pH and higher organic matter content, both of which might be expected to promote greater adsorption and longer persistence(3). Furthermore, the more rapid loss in clayey soil is consistent with the hypothesis that the 2,4-D is dissociated into its anions in most soils where it is more readily available to microorganisms(3). In a silt loam soil, over 70% of the ring carbon mineralized to CO2, about 20-25% was incorporated into soil as newly generated microbial tissue and about 1-2% remained undegraded after 58 days of incubation(6).
Bioaccumulative potential
Bluegill (lepomis machrochirus) exposed outdoors in plastic pool to one 2 mg/l application of (14)c-labeled 2,4-d dimethylamine salt. during 12-wk exposure, incorporation of (14)c into fatty acids, glycogen & protein material accounted for 85% of (14)c activity.
Mobility in soil
The Koc for the 2,4-D dimethylamine ranged from 72 to 136 for 3 soils in 48 hr batch experiments using radiolabeled herbicide(1). According to a classification scheme(2), this estimated Koc value suggests that 2,4-D dimethylamine is expected to have high mobility in soil(SRC). Effluent breakthrough curves measured in the same soils showed that the 2,4-D dimethylamine was almost as mobile as the water at 5000 ppm but considerably slower at 50 ppm, a result consistent with the non-linear adsorption isotherms(1). Adsorption constants for 2,4-D dimethylamine ranged from 0.13 to 0.25(3,4); these values were calculated from a field study performed using a plastic pool containing clay-loam hydrosoil(3,4).

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.
