12.2 Persistence and degradability
AEROBIC: Under aerobic soil metabolism conditions, triclopyr, at 1 ppm, degraded with half-lives of 8 and 18 days in silty clay loam and silt loam soils, respectively(1). The non-volatile degradates observed during the study were 3,5,6-trichloro-2-pyridinol (TCP) and 3,5,6-trichloro-2-methoxypyridine (TMP)(1); they were not persistent (max concns of 26 and 8%, respectively, were seen after <30 days of incubation)(1). The ultimate degradate was carbon dioxide (at 300 days post-treatment, approx 70 and 80% of the applied radioactivity in the silt loam and silty clay soils, respectively)(1). Triclopyr degraded slowly (half-life = 142 days) in a silty clay soil:water system incubated aerobically for 30 days(1). The only degradate observed was 3,5,6-trichloro-2-pyridinol at <5% of the amount applied after 30 days(1). Triclopyr was applied to the top layer of a column packed with loam soil(1). Water, equivalent to 2.5 cm of precipitation was leached through the column every second day(1). After 54 days, residues of triclopyr were found in the 10-cm layers of the soil; the residues were triclopyr and the metabolites, 3,5,6-trichloro-2-pyridinol and 2-methoxy-3,5,6-trichloropyridine, accounting for 5,85, and 10%, respectively, of the total of the residues which, in turn, was equivalent to 65% of the amount applied to the top layers(1). No residues were detected in the lower soil layers(1).
12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated for triclopyr(SRC), using an estimated log Kow of 2.53(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Koc values for triclopyr range from 1.5 to 134 at pH values of 5.0 to 7.7(1). According to a classification scheme(2), these Koc values suggest that triclopyr will have very high to high mobility in soil(SRC). Based on adsorption/desorption studies using sand, sandy loam, silt loam, and clay loam soils, unaged triclopyr was very mobile. Freundlich Kd values ranged from 0.165 to 0.975 ml/g(3); Kocs were 25-384 ml/g. Adsorption was not correlated with CEC or organic carbon content(3). Kd values for triclopyr on four soils ranged from 0.08 to 0.61 ml/g(4).
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.
