Persistence and degradability
The biodegradability of org substances in wastewater by activated-sludge was determined. beta-hydroxynaphthoic acid was resistant to degradation.
Bioaccumulative potential
The BCF values of 3-hydroxy-2-naphthalenecarboxylic acid at water concentrations of 0.1 and 1.0 mg/l were 6.7 or lower, measured in carp over an 6 week exposure period(1). According to a classification scheme(2), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of 3-hydroxy-2-naphthalenecarboxylic acid is estimated as 1,100(SRC), using a measured log Kow of 3.05(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 3-hydroxy-2-naphthalenecarboxylic acid is expected to have low mobility in soil. The pKa of 3-hydroxy-2-naphthalenecarboxylic acid is 2.79(4), indicating that this compound will exist as an anion in moist soils(SRC) and the mobility of anions is usually much greater than neutral species(5).
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.
