• Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Benz(a)anthracene, at a concentration of 0.05 ppm in the presence of 50 ug/L activated sludge, produced <0.1 percent carbon dioxide in 5 days(1). A biodegradation study of benz(a)anthracene, based on theoretical biochemical oxygen demand (BOD) measurements, using an Ashland City activated sludge seed (2,500 mg/L), a Nashville activated sludge seed (2,500 mg/L) and a Franklin sludge seed (2,500 mg/L) and an initial concentration of 500 mg/L benz(a)anthracene, achieved 0.3, 2.1, and 1.6 percent of its theoretical BOD, respectively, after 144 hours; using an Ashland City activated sludge seed (5,000 mg/L), a Nashville activated sludge seed (5,000 mg/L) and a Franklin sludge seed (5,000 mg/L) and an initial concentration of 500 mg/L benz(a)anthracene, benz(a)anthracene achieved 1.0, 1.0, and 5.4 percent of its theoretical BOD, respectively, after 144 hours(2). No biodegradation of benz(a)anthracene (initial concentration 10 ug/L) to carbon dioxide in estuarine water was observed after an incubation period of 48 hours(3).

12.3 Bioaccumulative potential

The log bioaccumulation factor for benz(a)anthracene in lake trout (Salvelinus namaycush) obtained from Lake Superior was 3.98(1). An estimated BCF of 2,940 was calculated in fish for benz(a)anthracene (SRC), using a measured log Kow of 5.76(2) and a regression-derived equation(3). According to a classification scheme(4), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC), provided the compound is not metabolized by the organism(SRC).

12.4 Mobility in soil

Benz(a)anthracene was determined to strongly adsorb to sediment with a Koc range of 545,000 to 1,870,000 in Coyote Creek sediment, Des Moines River sediment, and Searsville Pond sediment(1). According to a recommended classification scheme(2), these experimental Koc values suggest that benz(a)anthracene is expected to be immobile in soil(SRC). In a modeling study, 55, 71 and 88 percent of the benz(a)anthracene was predicted to be sorbed in a lake, stream, and eutrophic pond respectively(1). 39 percent of the benz(a)anthracene added to the water column of a controlled ecosystem was recovered in the sediment a week later(3). Benz(a)anthracene, which adsorbed to sediments in a microcosm, was mostly (40 to 60 percent) found in surface sections collected 4 to 5 cm below the surface(4). Sandy soil from a former wood impregnation plant and heterogeneous soil from a former tar-oil refinery were found to adsorb 105.8 and 95.7 mg/kg soil benz(a)anthracene, respectively(5). In estuarine water, 53 percent benz(a)anthracene adsorbed on particles after 3 hours. After 3 hours incubation in natural seawater, 59 percent of 3 ug/L was taken up by suspended aggregates of dead phytoplankton cells and bacteria(6).

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.
