Chronic intoxication also is said to have caused yellowing of the conjunctiva or sclera. These reports of intoxication and ocular disturbances have come from the munitions industry where commonly there is exposure to a variety of substances, and it is difficult to be sure of the individual substance responsible. [R19] 1,3,5-TRINITROBENZENE WAS SUBJECTED TO DNA REPAIR ASSAY USING THE ESCHERICHIA COLI W3110/POLA+, P3478/POLA- SYSTEM, REVERSE MUTATION ASSAYS WITH HIS-SALMONELLA TYPHIMURIUM STRAINS TA1535, TA1537, TA1538, TA98, & TA100, & MITOTIC RECOMBINOGENIC TESTS WITH THE YEAST SACCHAROMYCES CEREVISIAE D5. TESTS WERE CARRIED OUT IN THE ABSENCE OF AN EXOGENOUS ACTIVATION SYSTEM & IN TISSUE HOMOGENATE-MEDIATED ASSAY USING AROCLOR 1254-INDUCED, MALE RAT-LIVER-DERIVED S9 MIX. 1,3,5-TRINITROBENZENE WAS DEMONSTRATED TO BE MUTAGENIC WITH SALMONELLA TYPHIMURIUM STRAINS TA1535, TA1537, TA1538, TA98, & TA100. THE S9 MIX REDUCED THE MAGNITUDE OF THE RESPONSES. [R20] Acute oral toxicity studies conducted with dogs indicate that trinitrobenzene is effectively absorbed by this route. [R21] Acute toxicity study has shown that trinitrobenzene, like dinitrobenzenes, induces methemoglobin formation in vivo, in rats, mice, and guinea pigs. [R21] A series of toxicity studies in rats, mice, and guinea pigs have indicated that orally administered trinitrobenzene causes liver damage and central nervous system damage. [R22] Slight irritant effects ie, excitability, violent swimming, opercular movement increases suggesting respiratory distress upon short term exposure to marine fish Kuhlia sandvicensis were observed at exposure levels of 100 ug/l, while moderate and violent reactions to the chemical were produced at exposures of 1,000 and 10,000 ug/l. No effects were noted on exposures to concentrations of 50 or 10 ug/l. [R23] The acute toxicity and bioconcentration factor of a series of nitrobenzene derivatives was determined for the guppy. Toxicity is found to be determined by both hydrophobicity (expressed by the octanol/water partition coefficient) and rate of reduction of the nitro group (expressed by either electrochemical halfwave recduction potential or Hammett sigma values). [R24] An IgA nephropathy model based on long-term oral administration of protein antigens was evaluated in three mouse strains using trinitrophenyl (TNP)-conjugated ovalbumin. Administration of the antigen for 14 weeks did not induce a significant IgA response nor deposition of IgA in the mesangium in any of the mouse strains. If, however, serum Iga anti-TNP antibodies were induced by intraperitoneal injection of anti-TNP producing MOPC-315 tumor cells, subsequent intravenous injection of antigen resulted in the deposition of IgA immune complexes in the mouse kidneys. Hematuria did not occur. Previous data showing that long-term oral administration of protein antigens induces mesangial IgA deposits could not be comfirmed with TNP ovalbumin. However, mesangial IgA deposits could not be confirmed with TNP ovalbumin. [R25] 1,3,5-Trinitrobenzene may be released to the environment in wastewater from the manufacture of 2,4,6-trinitrotoluene (TNT) or from the disposal of some TNT wastes. If released to soil, 1,3,5-trinitrobenzene is expected to be moderately to highly mobile. This compound has the potential to photolyze on soil surfaces. Volatilization from soil surfaces is predicted to be an insignificant fate process. Insufficient data are available to predict the significance of biodegradation in soil or water. If released to water, 1,3,5-trinitrobenzene may be subject to direct photolysis. Bioaccumulation in aquatic organisms, adsorption to suspended solids and sediments, and volatilization are not expected to be environmentally important fate processes. If released to the atmosphere, 1,3,5-trinitrobenzene is expected to exist partly in the vapor phase and partly adsorbed onto particulate matter. Direct photolysis and wet deposition are potential removal mechanisms. (SRC) 1,3,5-Trinitrobenzene may be released to the environment in wastewater from the manufacture of 2,4,6-trinitrotoluene (TNT) or from the disposal of some TNT wastes(1,2,SRC). [R26] TERRESTRIAL FATE: If released to soil, 1,3,5-trinitrobenzene is expected to be moderately to highly mobile. This compound has the potential to photolyze on soil surfaces. Volatilization from soil surfaces is predicted to be an insignificant fate process. Insufficient data are available to predict the significance of biodegradation in soil. (SRC) AQUATIC FATE: If released to water, 1,3,5-trinitrobenzene may be subject to direct photolysis when exposed to sunlight. Bioaccumulation in aquatic organisms and volatilization are not expected to be environmentally important fate processes. 1,3,5-Trinitrobenzene should exhibit moderate to low adsorption to suspended solids and sediments. Insufficient data are available to predict the significance of biodegradation in water. (SRC) ATMOSPHERIC FATE: The extrapolated vapor pressure of 1,3,5-trinitrobenzene at 20 deg C is 3.2X10-6 mm Hg(1). Based on this vapor pressure, 1,3,5-trinitrobenzene is expected to exist partly in the vapor phase and partly adsorbed onto particulate matter in the atmosphere(2,SRC). This compound may be subject to direct photolysis. A water solubility of 340 mg/L at 20 deg C(1) suggests that wet deposition is a potential fate process(SRC). [R27] THE MICROBIAL DEGRADATION OF 1,3,5-TRINITROBENZENE WAS INCOMPLETE & UNSUSTAINED IN TENNESSEE RIVER WATER. NITRO GROUP REDUCTION OCCURRED IN THE PRESENCE OF ADDED NUTRIENTS & LAB CULTURES OF TENNESSEE RIVER MICROORGANISMS. [R28] Simulated biological treatment system, consisting of an aerator inoculated with A. agilis (first stage) and an activated sludge system (2nd stage), initial concn 118-146 mg/L nitroaromatic compounds, 96-98% removal in first stage and 2-4% removal in second stage(1). 1,3,5- Trinitrobenzene at an initial concn of 100 ppm was found to be resistent to biodegradation when incubated 180 minutes in a Warburg respirometer inoculated with a phenol-adapted mixed culture of microorganisms obtained from garden soil, compost, river sediment, and a petroleum refinery waste lagoon(2). [R29] 1,3,5- Trinitrobenzene contains chromophores which absorb UV light in the environmentally significant range (wavelengths greater than 290 nm)(1,SRC). This suggests that this compound has the potential to photolyze when exposed to sunlight(SRC). Aromatic nitro compounds are generally resistant to chemical hydrolysis under environmental conditions(2). The half-life for the reaction of 1,3,5-trinitrobenzene vapor with photochemically generated hydroxyl radicals in the atmosphere has been estimated to be 35 years based on an estimated reaction rate constant of 1.3E-15 cu cm/molecule-sec at 25 deg C and an average hydroxyl radical concentration of 5.0X10+5 molecule/cu cm(3,4,SRC). [R30] Bioconcentration factors (BCF) of 5 and 23 have been estimated for 1,3,5- trinitrobenzene using regression equations(1) based on a log octanol/water partition coefficient of 1.18(2) and a water solubility of 340 mg/L at 20 deg C(3), respectively(SRC). These BCF values suggest that this compound would not bioaccumulate significantly in aquatic organisms(4,SRC). [R31] Adsorption coefficients (Koc) of 104 and 178 have been estimated for 1,3,5-trinitrobenzene using regression equations(1) based on a log octanol/water partition coefficient of 1.18(2) and a water solubility of 340 mg/L at 20 deg C(3), respectively(SRC). These Koc values suggest that this compound has moderate to high mobility in soil and exhibits moderate to low adsorption to suspended solids and sediments in water(4,SRC). [R32] Henry's Law constant for 1,3,5-trinitrobenzene has been estimated to be 3.08X10-9 at 25 deg C using a method of group structural estimation method (1,SRC). Based on this value of Henry's Law constant, volatilization from water is not expected to be an environmentally important fate process(2,SRC). [R33] Groundwater Grand Island, NE, detected 1,3,5-trinitrobenzene in 2,4,6-trinitrotoluene (TNT) contaminated wells in the vicinity of an Army munitions facility(1). [R34] Detected 1,3,5-trinitrobenzene in effluent from the production and purification of 2,4,6-trinitrotoluene (TNT), 54 samples collected over a period of 1 year, 3.8% pos, detection limit not reported, concn range 0.06-0.30 mg/l(1). [R35] Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 10 lb or 4.54 kg. The toll free number of the NRC is (800) 424-8802; In the Washington D.C. metropolitan area (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b). [R36] RCRA: As stipulated in 40 CFR 261.33, when 1,3,5-trinitrobenzene, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5). [R37] EPA Method 8090: Nitroaromatics and Cyclic Ketones.
