| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1,100(SRC), determined from a measured log Kow of 3.05(2) and a regression-derived equation(3), indicates that 3-hydroxy-2-naphthalenecarboxylic acid is expected to have low mobility in soil(SRC). The pKa of 3-hydroxy-2-naphthalenecarboxylic acid is 2.79(4), which indicates that this compound will exist primarily as an anion in moist soil and the mobility of anions is usually much greater than neutral species(5). Volatilization of 3-hydroxy-2-naphthalenecarboxylic acid from moist soil surfaces is not expected to be an important fate process since anions do not volatilize. 3-Hydroxy-2-naphthalenecarboxylic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 5.4X10-7 mm Hg(SRC), determined from a fragment constant method(6). The results of a single screening study using an activated sludge inoculum(7) suggest that 3-hydroxy-2-naphthalenecarboxylic acid is biodegraded slowly in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1,100(SRC), determined from a measured log Kow of 3.05(2) and a regression-derived equation(3), indicates that 3-hydroxy-2-naphthalenecarboxylic acid is expected to adsorb to suspended solids and sediment(SRC). The pKa of 3-hydroxy-2-naphthalenecarboxylic acid is 2.79(4), which indicates that this compound will exist primarily as an anion in water and may not absorb to suspended solids and sediments as much as the neutral species (SRC). Volatilization from water surfaces is not expected to be an important environmental fate process since anions do not volatilize(SRC). According to a classification scheme(5), BCF values of 6.7 or lower measured in carp(6), suggest bioconcentration in aquatic organisms is low(SRC). A 1.3% of its theoretical BOD in 2 weeks using an activated sludge inoculum and the Japanese MITI test(6) suggests that 3-hydroxy-2-naphthalenecarboxylic acid is biodegraded slowly in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 3-hydroxy-2-naphthalenecarboxylic acid, which has an estimated vapor pressure of 5.4X10-7 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 3-hydroxy-2-naphthalenecarboxylic acid is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 16 hours(SRC), calculated from its rate constant of 2.4X10-11 cu cm/molecule-sec at 25 °C(SRC) determined using a structure estimation method(3). Particulate-phase 3-hydroxy-2-naphthalenecarboxylic acid may be removed from the air by wet and dry deposition(SRC). 3-Hydroxy-2-naphthalenecarboxylic acid absorbs light in the environmental UV spectrum(4) and may be capable of undergoing photolysis, but the rate of this reaction is not known(SRC). |
| Unerwünschte Wirkungen | Occupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation. |
| Expositionspfade | The substance can be absorbed into the body through the skin and by ingestion. |
| Signs and Symptoms | Sore throat. Cough.Redness. Pain.Redness. Pain. Burns.Sore throat. Nausea. Vomiting. Diarrhoea. |
| ICSC Environmental Data | The substance is harmful to aquatic organisms. |
| Soil Adsorption/Mobility | 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). |
| Artificial Pollution Sources | 3-Hydroxy-2-naphthalenecarboxylic acid's production and use in dyes and pigments(1) may result in its release to the environment through various waste streams(SRC). |
| Environmental Biodegradation | THE BIODEGRADABILITY OF ORG SUBSTANCES IN WASTEWATER BY ACTIVATED-SLUDGE WAS DETERMINED. BETA-HYDROXYNAPHTHOIC ACID WAS RESISTANT TO DEGRADATION.3-Hydroxy-2-naphthalenecarboxylic acid, present at 100 mg/l, reached 1.3% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/l and the Japanese MITI test(1). |
| Environmental Bioconcentration | 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). |
| Volatilization from Water/Soil | The Henry's Law constant for 3-hydroxy-2-naphthalenecarboxylic acid is estimated as 1.4X10-9 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 3-hydroxy-2-naphthalenecarboxylic acid is expected to be essentially nonvolatile from water surfaces(2). Furthermore, 3-hydroxy-2-naphthalenecarboxylic acid is a weak acid with pKa of 2.79(2), indicating that this compound will exist as an anion in the environment, and anions do not volatilize from water or soil surfaces(SRC). 3-Hydroxy-2-naphthalenecarboxylic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 5.4X10-7 mm Hg(SRC), determined from a fragment constant method(4). |
