12.2 Persistence and degradability
AEROBIC: Half-lives for biodegradation of 2,4,5-TP in three Saskatchewan, Canada prairie soils were 13, 13 and 10 days for heavy clay loam, clay loam and sandy loam, respectively(1). Negligible degradation was observed in air-dried soils(1). Biodegradation of 2,4,5-TP was tested in Mardin, Honeoye and Dunkirk silt loam soil samples from areas in NY, resulting in complete disappearance in greater than 47, 124 and 205 days, respectively(2). 2,4,5-TP was shown to have an aerobic half-life of 16 days in soil(5). 2,4,5-Trichlorophenol has been identified as a product of the biodegradation of 2,4,5-TP(6). 2,4,5-TP was shown to have a half-life of 8 and 10 days in sandy loam, 15 and 21 days in forest soil, 13 days in clay loam and 14 days in grassland soil(7). In soil, 2,4,5-TP was reported to degrade more slowly than 2,4-D(8). No biodegradation of 2,4,5-TP was observed after 50 days incubation in Hamilton Harbour water from Ontario, Canada(3). An initial concn of 2,4,5-TP of 107.5 ppm was completely degraded in lagoon water in 9 days after 100 ml of 2,4,5-trichlorophenol acclimated water was added and incubated at 20 to 21 deg C with constant aeration(4). 2,4,5-TP, incubated at 25 deg C with sewage sludge in an aeration tank for 47 days gave an unchanged concentration of the S enantiomer and a 40% decrease in the R enantiomer(9).
12.3 Bioaccumulative potential
A BCF of 58 was reported in fish in flowing water for 2,4,5-TP(1). According to a classification scheme(2), this BCF data suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). 2,4,5-TP does not appear to bioconcentrate more than 10 fold(3).
12.4 Mobility in soil
Log Koc values for 2,4,5-TP have been reported as 1.87 and 2.03(1), giving Koc values of 74 and 107. According to a classification scheme(2), these Koc values suggest that 2,4,5-TP will have high mobility in soil(SRC). 2,4,5-TP had sorption values of 2.7-5.9 mg/kg at different conditions in soil with a pH of 7.4, and sorption values of 0.2-1.1 mg/kg in soil with a pH of 8.2(3). 2,4,5-TP had reported sorption coefficients of 308-9016 mL/g(4). 2,4,5-TP is expected to be negatively charged and will not be readily absorbed making it more mobile in soil(5). The pKa of 2,4,5-TP is 2.84(6), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(7).
12.5 Other adverse effects
no data available
SECTION 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.
