    12.Ecological information

    12.1 Toxicity

    • Toxicity to fish: no data available
    • Toxicity to daphnia and other aquatic invertebrates: EC50; Daphnia magna (water flea) 48 hr, semi-static conditions, 0.003 mg/L.
    • Toxicity to algae: EC50; Pseudokirchneriella subcapitata (green algae) 72 hr, static conditions, 0.002 mg/L, biomass.
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: 2-Hydroxy-4-(octyloxy)benzophenone, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Using OECD Guideline 301B (Ready Biodegradability: CO2 Evolution Test) and a non-adapted activated sludge inoculum, 2-hydroxy-4-(octyloxy)benzophenone (at 10.7 and 20.2 mg/L) achieved 5-6% CO2 evolution after 28 days of incubation which classified the compound as not readily biodegradable(2).

    12.3 Bioaccumulative potential

    BCF range of 70-190 was determined in fish for 2-hydroxy-4-(octyloxy)benzophenone(SRC), using carp (Cyprinus carpio) which were exposed over a 60-day period(1). According to a classification scheme(2), this BCF range suggests the potential for bioconcentration in aquatic organisms is moderate to high(SRC).

    12.4 Mobility in soil

    Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2-hydroxy-4-(octyloxy)benzophenone can be estimated to be 6.4X10+4(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-hydroxy-4-(octyloxy)benzophenone is expected to be immobile in soil.

    12.5 Other adverse effects

    no data available

    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.
