- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
12.2 Persistence and degradability
AEROBIC: 2-Naphthol, present at 100 mg/L, reached 68.4% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). In an OECD 301C test, 2-naphthol achieved an observed BOD of 68% after 28 days; the test substance is considered to be readily biodegradable under the conditions of the test(2). 2-Naphthol biodegraded 99.83, 99.98, 99.88, 99.90% after 100, 130, 150, 160 days, respectively, in a biodegradation study using activated sludge(3). Using adapted activated sludge as the inoculum, 2-naphthol degraded 89% based on COD removal at a biodegradation rate of 39.2 mg COD/g-hr(4). The biodegradation potential of 2-naphthol in diluted primary digested sludge was considered to be inhibitory to biodegradation after a lag period of more than 75 days(5). The 5-day BOD of 2-naphthol, present at 5 ppm, was 0.71 g/g or 27.8 of the Theoretical Oxygen Demand(6). In a Chernozem soil at 19°C, 2-naphthol existed for > 90 days at 500 mg/kg and for 30 days at 5 mg/kg(7). 2-Naphthol is considered to be recalcitrant in Chernozem soils(8).
12.3 Bioaccumulative potential
An estimated BCF of 28 was calculated in fish for 2-naphthol(SRC), using a log Kow of 2.7(1) and a regression-derived equation(2). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
The Koc of 2-naphtol is estimated as 390(SRC), using a log Kow of 2.7(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-naphthol is expected to have moderate mobility in soil. The pKa of 2-naphthol is 9.51(4), indicating that this compound will exist partially in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
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.
