AEROBIC: 2-Methylpyridine was reported as readily biodegradable in the MITI test(1). In an aerobic screening test using an enrichment culture obtained from soil as an inoculum, 100% degradation was obtained in 14 to 32 days(2). When this test was repeated under anaerobic conditions, degradation was much slower, requiring >97 days for complete biodegradation(2). Only 2.7% of the added 2-methylpyridine (initial concentration of 2 umoles/g) remained after 16 days following incubation in a silt loam soil(3). Complete biodegradation of 2-methylpyridine, initially added at 4 mg/L, was reported in aerobic groundwater incubated at 15°C for 4 days(4). In an aerobic column study where subsurface sediment was leached with contaminated groundwater, 65% of the initially applied 2-methylpyridine was removed after 5 weeks of operation(5). Complete biodegradation of 2-methylpyridine was observed in 24 days following incubation in a defined medium inoculated with soil(6). Contaminated groundwater, from the American Creosote Works Superfund site in Pensacola, FL, was incubated with 2-methylpyridine; 33, 33, 33, 66, and 100% degradation was reported after incubation for 1, 3, 5, 8, and 14 days, respectively(7). 2-Methylpyridine, present at 100 mg/L, reached 0.1% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(8).
12.3 Bioaccumulative potentialAn estimated BCF of 3 was calculated for 2-methylpyridine(SRC), using a log Kow of 1.11(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). Low bioconcentration was reported for tests using carp (Cyprinus carpio)(4); however, actual BCF values were not available(SRC).
12.4 Mobility in soilThe sorption behavior of 2-methylpyridine was studied in soil column tests using 5 Eurosoil reference soils having organic carbon content ranging from 0.33-1.85% and pH ranging from 5.2-8.6(1); measured Kd values ranging from 0.08 to 6.52(1) correspond to calculated Koc values of 4, 38, 70, 100 and 215(SRC); the lowest Koc value of 4 corresponds to Eurosoil 2 which had the highest pH value(8.6). The pKa of 2-methylpyridine is 5.96(2), indicating that this compound will exist partially in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(3). In the Eurosoil column tests(1), lowest adsorption occurred when 2-methylpyridine was in non-ionized form(1). Sorption of 2-methylpyridine to soil is primarily controlled by cation exchange and surface complex formation(1,4). According to a classification scheme(5), the Koc values suggest that 2-methylpyridine is expected to have very high to moderate mobility in soil.

13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
