12.2 Persistence and degradability

AEROBIC: Aerobic aqueous screening test data showed a 84 and 95% loss of 0.1 ppm 2-methylnaphthalene in 1 and 5.6 days, respectively, for acclimated sewage inoculum and did not degrade with unacclimated sewage(1). When marine water was used to inoculate, 2-methylnaphthalene at a concentration of 0.067 ppm disappeared within 10 days under aerobic conditions at 25°C(2). Using the Japanese MITI I procedure, <5% degradation of 2-methylnaphthalene occurred in 28 days; however, for the MITI II test with a freshwater inoculum, 72% was lost in 28 days under aerobic conditions at 25°C(3). 2-Naphthoic acid was identified as a microbial co-oxidation product of 2-methylnaphthalene by mixed cultures of Norcardia sp. isolated from soil(4). 2-Methylnaphthalene showed a lag-period of two weeks, and then rapid degraded to 17% residual in the two weeks following the lag period and was not detected after 25 weeks, in a study using microcosms filled with soil (1.1% organic carbon, 6.5% kaolin) material and a coal derived wood-preservative(5). 2-Methylnaphthalene was aerobically biodegraded 100% in 4 different northern soils (arctic diesel fuel contaminated, PCB and associated oil contaminated, creosote-PAH contaminated, uncontaminated) incubated at 7 and 20°C for 90 days(6).

12.3 Bioaccumulative potential

After 2, 3 and 5 weeks exposure, the BCF of 2-methylnaphthalene in the muscle tissue of Coho salmon (Onchorhynchus kisutch) was 30, 100 and 190, respectively. The BCF dropped to 70 within one week following 6 weeks exposure(1). After 2 weeks exposure, the average BCF of 2-methylnaphthalene in the muscle tissue of Starry flounder (Platichthys stellatus) was 895(1). BCF values in sheepshead minnows (Cyprinidon variegatus) exposed for 36 days to 2.46 and 23.63 ug/L of 2-methylnaphthalene were 2852 and 2921, respectively(2). Exposure of fingerling rainbow trout to 14C-(8)-2-methylnaphthalene (2573 dpm/ug) at 0.02 mg/L for four weeks in a continuous- flow delivery system resulted in maximum tissue levels from 40 to 300 times the water concentration; maximum bile 14C levels were 23,500 times the water concentration(3). A BCF of 407 has been reported for bluegill sunfish after exposure to 14C-(8)-2-methylnaphthalene at 0.013 ug/L for 26 days in a continuous-flow delivery system(4). According to a classification scheme(5), these BCF values suggest that 2-methylnaphthalene bioconcentration in aquatic organisms is low to very high(SRC), provided the compound is not metabolized by the organism(SRC). A BCF of 8.1 was reported for 2-methylnaphthalene in clams after 24 hours of exposure to a water concentration of 2-methylnaphthalene of 480 ug/L(6). The biota-sediment accumulation factor for 2-methylnaphthalene determined using oligochaete worm (Lumbriculus variegatus) was 4.2 and 0.11 in Lake Erie sediment from Vermilion, OH and Dunkirk, NY, respectively(7).

12.4 Mobility in soil

A log Koc value of 3.67 was reported in soil(1). An average sediment- or soil-water partition coefficient (log Kp) for 2-methylnaphthalene of 2.00 was determined from 17 measurements(2). The log Koc values for 2-methylnaphthalene in 75 sediment samples was 3.00-5.96(3). Measured Koc values have been reported as 4,400(4) and 8,500(5) for 2-methylnaphthalene. According to a classification scheme(6), these Koc values suggest that 2-methylnaphthalene is expected to have slight to no mobility in soil.

12.5 Other adverse effects

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.
