/AQUATIC SPECIES/ The importance of nitroaromatic compounds as aquatic contaminants and the association of superoxide (O2-) mediated toxicity with the mammalian metabolism of a number of these compounds has led our laboratory to conduct an in vitro investigation of nitroaromatic-stimulated O2- production by freshwater fish. Utilizing cytochrome c reduction and cyanide-insensitive oxygen consumption assays for O2-, channel catfish (Ictalurus punctatus), largemouth bass (Micropterus salmoides) and rainbow trout (Salmo gairdneri) hepatic microsomes were exposed to nitrofurantoin (NF), p-nitrobenzoic acid (PNBA) and m-dinitrobenzene (MDNB). NF and PNBA were chosen for study as model nitroaromatic compounds, known to stimulate microsomal O2- generation in mammals; MDNB was chosen because it frequently contaminates aquatic systems. The results demonstrated that each of the three nitroaromatics is capable of significantly enhancing superoxide dismutase (SOD) inhibitable cytochrome c reduction and oxygen consumption, providing specific evidence of stimulated microsomal production of O2- by the fish species examined. The results also indicated chemical- and species-specific differences in stimulated O2- production. In both assay systems, enhancement by NF exceeded that produced by MDNB and, more pronouncedly, PNBA. Furthermore, although similar responses to all nitroaromatics were observed in microsomes isolated from catfish and bass, the assays employing trout microsomes demonstrated the greatest enhancement in NF and MDNB exposures. These findings suggest that the stimulation of O2- production may be an important mode of action for these common aquatic pollutants that merits further ecotoxicological assessment.
14-DAY STUDY IN RATS Groups of five male and five female rats were given 0, 2,500, 5,000, 10,000, 20,000, or 40,000 ppm p-nitrobenzoic acid in feed for 14 days. All rats survived until the end of the study. Male and female rats given 20,000 and 40,000 ppm lost weight. The final mean body weights of 10,000, 20,000, and 40,000 ppm males were 82%, 60%, or 52% that of the controls, and the final mean body weights of 10,000, 20,000, and 40,000 ppm females were 87%, 68%, and 65% that of the controls. There were no clinical findings that were characteristic of organ-specific toxicity. Absolute and relative spleen weights were significantly increased in rats exposed to 10,000, 20,000, and 40,000 ppm. There were decreases in erythrocyte count and hemoglobin and hematocrit values and increases in reticulocyte count, nucleated erythrocytes, and methemoglobin concentration that were most pronounced in the 20,000 and 40,000 ppm groups.

4-Nitrobenzoic acid's production and use in manufacturing intermediates and as a reagent for alkaloids and thorium(1) may result in its release to the environment through various waste streams(SRC).
TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 250(SRC), determined from a log Kow of 1.89(2) and a regression-derived equation(3), indicates that 4-nitrobenzoic acid is expected to have moderate mobility in soil(SRC). The pKa of 4-nitrobenzoic acid is 3.44(4), indicating that this compound will exist almost entirely 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). Volatilization of 4-nitrobenzoic acid from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.8X10-10 atm-cu m/mole(SRC), using a fragment constant estimation method(6). 4-Nitrobenzoic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.5X10-6 mm Hg(SRC), determined from a fragment constant method(7). 4-Nitrobenzoic acid may biodegrade in soil(SRC) based on 62% degradation after 2 weeks in activated sludge inoculum during a Japanese MITI test(8), however, it took more than 64 days to decompose in a soil microflora inoculum with mineral salts medium(9).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 250(SRC), determined from a log Kow of 1.89(2) and a regression-derived equation(3), indicates that 4-nitrobenzoic acid is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 3.8X10-10 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). A pKa of 3.44(5) indicates 4-nitrobenzoic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(6). According to a classification scheme(7), an estimated BCF of 3.2(SRC), from its log Kow(2) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). 4-Nitrobenzoic acid is expected to biodegrade in water(SRC) based on 62% degradation after 2 weeks in activated sludge inoculum during a Japanese MITI test(9) and where it reached 52% of its BOD in river water collected from the Songhua River, China after 5 days(10).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 4-nitrobenzoic acid, which has an estimated vapor pressure of 2.5X10-6 mm Hg at 25 °C (SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 4-nitrobenzoic 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 27 days(SRC), calculated from its rate constant of 5.9X10-13 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase 4-nitrobenzoic acid may be removed from the air by wet or dry deposition(SRC). 4-Nitrobenzoic acid, in isopropanol, was reduced at a wavelength of 316 nm to 4-aminobenzoic(4). Therefore, 4-nitrobenzoic is expected to undergo direct photolysis(SRC). The C6H4COOH radical was generated by photolysis of 4-nitrobenzoic acid using spin-trapping of photolysis products(5).
The rate constant for the vapor-phase reaction of 4-nitrobenzoic acid with photochemically-produced hydroxyl radicals has been estimated as 5.9X10-13 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 27 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). A study in aqueous media involving the reactivity of aromatic compounds toward hydroxyl radicals found that the reaction rate of the p-nitrobenzoate ion toward hydroxyl radicals is 1.17X10-9 per M per sec(2). 4-Nitrobenzoic acid is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). 4-Nitrobenzoic acid, in isopropanol, was reduced at a wavelength of 316 nm to 4-aminobenzoic acid(4). Therefore, 4-nitrobenzoic acid is expected to undergo direct photolysis(SRC). The C6H4COOH radical was generated by photolysis of 4-nitrobenzoic acid using spin-trapping of photolysis products(5).
An estimated BCF of 3.2 was calculated for 4-nitrobenzoic acid(SRC), using a log Kow of 1.89(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
The Koc of 4-nitrobenzoic acid is estimated as 250(SRC), using a log Kow of 1.89(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 4-nitrobenzoic acid is expected to have moderate mobility in soil. The pKa of 4-nitrobenzoic acid is 3.44(4), indicating that this compound will exist almost entirely 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).
The Henry's Law constant for 4-nitrobenzoic acid is estimated as 3.8X10-10 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 4-nitrobenzoic acid is expected to be essentially nonvolatile from water surfaces(2). 4-Nitrobenzoic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.5X10-6 mm Hg(SRC), determined from a fragment constant method(3).
NIOSH (NOES Survey 1981-1983) has statistically estimated that 42,700 workers (12,407 of these are female) are potentially exposed to 4-nitrobenzoic acid in the US(1). Occupational exposure to 4-nitrobenzoic acid may occur through dermal contact with this compound at workplaces where 4-nitrobenzoic acid is produced or used(SRC).

4-Nitrobenzoic acid Use and Manufacturing
It is derived from the oxidation of p-nitrotoluene. The oxidant can be sodium dichromate, air, manganese ore powder, nitric acid and so on. Using p-nitrotoluene as raw material, in the presence of sulfuric acid, the oxidation reaction is carried out with sodium dichromate at 55°C to produce p-nitrobenzoic acid. The reaction liquid is filtered, centrifuged, dehydrated, washed and dried to obtain a finished product. In addition, the dextrorotation 1-p-nitrophenyl-2-amino-1, 3-propanediol in the production of chloramphenicol can be easily oxidized with nitric acid to obtain p-nitrobenzoic acid.
