10.3 Possibility of hazardous reactions
Behavior in fire: Melts and burns.Halogenated aliphatic compounds, such as DDT AND METABOLITES, are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. This material is incompatible with alkaline media.

12.2 Persistence and degradability
DDT is biodegraded by a number of microorganisms isolated from water, sediments and soils(1,2). Biodegradation under environmental conditions has been shown to be quite variable, however, with a number of factors playing a role, especially the presence of anaerobic conditions and high populations of the required microorganisms(1,2). In certain flooded soils, DDT is readily degraded with complete degradation in one soil in approximately 31 days(3). Degradation has been demonstrated in soils under anaerobic conditions, while little or no degradation was observed under aerobic conditions(1,2,4). Various amendments to soils such as energy and carbon sources, were shown to increase degradation under anaerobic but not aerobic conditions(1,4,5). Reported half-lives for DDT in soils range from 2 years to > 15 years(6-9). Using a river-die away test, no change in DDT concentration was found in raw river water over a period of 8 weeks(10). DDT incubated in 6 lake water samples was converted to DDD (1,1'-bis(p-chlorophenyl)-2,2-dichloroethane), with greater conversion in samples with large amounts of plankton - up to 95% conversion in one sample(1). Six marine water samples showed poor metabolic activity with respect to DDT degradation(11). DDT degradation of up to 67% in sediments in up to 24 weeks has been reported(12). DDT is apparently co-metabolized by microorganisms and is not used as a sole carbon source(1). Products of biodegradation include DDD and DDE (1,1'-bis(p-chlorophenyl)-2,2-dichloroethylene); occasionally DBP (4,4'-dichlorobenzophenone) is formed appreciably(1,2).
12.3 Bioaccumulative potential
The following BCF values have been reported for aquatic organisms: 600 to 84,500, fish(1,2); 51,000 to 100,000, fathead minnows(3,4). Bioconcentration factors of 5,100-24,400 were measured for carp exposed to 1 ug/L of DDT over a 10 week incubation period and BCF values of 6,080-25,900 were measured for carp exposed to 0.1 ug/L(5). According to a classification scheme(6), these BCF values suggest bioconcentration in aquatic organisms is very high(SRC).
12.4 Mobility in soil
The Koc of DDT ranges from 1.13X10+5(1) to 3.5X10+5(2). According to a classification scheme(3), these Koc values suggest that DDT is expected to be immobile in soil.
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.
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.
