Persistence and degradability
AEROBIC: 1-Naphthol was biodegradable in screening tests(1-5). It proved to be readily biodegradable in a respiratory biodegradation test (24 participating laboratories) similar to the MITI test but using an activated sludge inoculum(3). The median lag time was 3 days and a mean BOD of 60% of theoretical was achieved in 10 days thereafter; 82% of dissolved organic carbon (DOC) was removed(3). In a 2-week biodegradation screening test (MITI test) using 1-naphthol (30 ppm) and an activated sludge inoculum, 96% of theoretical BOD was removed(1). 92.1% of the chemical oxygen demand (COD) was removed in 24 hr in a degradability test using an acclimated activated sludge inoculum(2). In another 5-BOD test, 66-69% of the theoretical BOD was consumed(5).
Bioaccumulative potential
An estimated BCF of 31 was calculated for 1-naphthol(SRC), using a log Kow of 2.85(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). There is evidence that 1-naphthol is rapidly transformed in M edulis(4). Experiments conducted with the marine gastropod, Littorina littorea, show that the loss of 1-naphthol in seawater was greater when animals were present in the experimental tanks(4).
Mobility in soil
Batch equilibrium adsorption studies of 1-naphthol were performed using 16 soils and sediments(1). The Koc average value using ten of these soils was 522 which was in good agreement with that predicted from the octanol-water partition coefficient (hydrophobic adsorption), 432(1); the other six soils and sediments yielded Koc value that were higher (1645, 1733, 2102, 2700, 4198, and 15,618) with the highest value (15, 618) measured in a sediment soil (0.11% organic carbon)(1); it was found that for 1-naphthol, hydrophobic adsorption is dominant only when the ratio of percent organic carbon to percent montorillonite exceeds 0.1% and that adsorption of 1-naphthol is a function of soil and sediment properties(1). According to a classification scheme(2), a Koc value of 522 (average) suggests that 1-naphthol is expected to have low mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
