Persistence and degradability
No degradation of 2,3,6-trichlorophenylacetic acid was observed when incubated with lake water/sediment or activated sludge under aerobic conditions or with a sandy loam soil in water under anaerobic conditions(1). More than 75% of 2,3,6-trichlorophenylacetic acid remained after 120 day biodegradation studies in lake water (Oneida Lake, NY), primary sewage effluent, soil, and soil/water suspensions; adding supplemental nutrients deceases the amount remaining to 40% after 120 days in soil inoculum while little effect was observed using other media. Cometabolic degradation may be the major biodegradation process for 2,3,6-trichlorophenylacetic acid in aquatic systems(2). A dichlorohydroxybenzene derivative was tentatively identified as a product of the biodegradation of 2,3,6-trichlorophenylacetic acid in soil(2). 2,3,6-Trichlorophenylacetic acid was described as being susceptible to decarboxylation reactions when incubated with soil inoculum(3).
Bioaccumulative potential
Experimental bioconcentration factors ranging from 1.6 to 11.6 in bluegills (Lepomis macrochirus) were determined in static tests with a 2,3,6-trichlorophenylacetic acid concentration of 2 ppm(1). Based on an experimental log Kow of 3.20 for 2,3,6-trichlorophenylacetic acid, obtained in 0.1 and 0.5 M HCl(2), and its water solubility, 200 mg/L at 28 deg C(3), estimated bioconcentration factors ranging from 31 to 159 can be calculated(SRC) using an appropriate regression equation(4). The magnitude of these values indicate that bioconcentration in fish and aquatic organisms will not be a significant process(SRC).
Mobility in soil
Experimental soil adsorption coefficients ranging from 0.3 to 667 on four different sediments with percent organic carbon ranging from 0.3 to 54 were observed at pH 6.5; adsorption on organic muck was found to increase at pH 4.5 but not at pH 9(1). Soil pH, especially in the range 5.0-6.7, was described as the most important factor in 2,3,6-trichlorophenylacetic acid mobility(2-3). At neutral or basic pHs, 2,3,6-trichlorophenylacetic acid will exist predominately as the ionized acid and adsorption to soil will driven by ionic interactions between it and the soil while at more acidic pHs hydrophobic processes will predominate(4). Soil TLC experiments using a wide range of soils (Hagerstown silty clay loam, Lakeland sandy loam, Chillium silt loam) produced Rfs ranging from 0.38 to 1.0 indicating that 2,3,6-trichlorophenylacetic acid has a high degree of mobility compared to other pesticides(2-6).
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.
