体内負荷Dichlorobenzene was detected in whole blood (3.12 ng/g) and adipose tissue (2.28 ng/g) from the general population of Canada(1). 1,2-Dichlorobenzene was detected in the personal air of Los Angeles, CA residents at concns of 0.3-0.4 ug/cu m and residents of Contra Costa, CA at concns of 0.6 ug/cu m(2). 1,2-Dichlorobenzene was detected in the breath of Los Angeles, CA residents at concns of 0.04-0.1 ug/cu m and residents of Contra Costa, CA at concns of 0.08 ug/cu m(2).
TreatmentFollowing oral exposure, administer charcoal as a slurryadminister oxygen to all cyanotic or symptomatic patients. In case of methemoglobinemia, administer 1 to 2 mg/kg of 1% methylene blue slowly IV in symptomatic patientsalso consider adjunctive therapy. In case of inhalation exposure, move patient to fresh airmonitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. Following eye exposure, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. Following dermal exposure, skin should be thoroughly washed with soap and watercontaminated clothing and shoes should be discarded. Administer 100 percent humidified supplemental oxygen with assisted ventilation as required. Treat for methemoglobinemia and sequelae. Signs and symptoms of methemoglobinemia may be delayed. (T36)
相互作用Effect of 1,2-DCB on sulfur metabolism as measured in the urine was studied in 5 dogs given 50 mg/kg bw or 250 mg/kg bw 1,2-DCB. ...Urinary output of sulfur was increased in 1,2-DCB dosed animals compared to controls.The hepatic toxicity of ortho-dichlorobenzene was studied in Fischer 344 rats given methyl palmitate in order to inhibit Kupffer-cell function or superoxide dismutase (conjugated to polyethylene glycol) to scavenge superoxide anions. Administration of either compound dramatically reduced the severity of ortho-dichlorobenzene-induced liver injury, and both agents reduced the increase in plasma alanine aminotransferase activity by 80%light microscopic examination confirmed that the reductions in enzyme activity reflected protection from hepatocellular injury. Interestingly, methyl palmitate did not protect against ortho-dichlorobenzene-induced hepatotoxicity in phenobarbital-pretreated rats, and the degree of inhibition of hepatotoxicity by polyethylene glycol-superoxide dismutase was not significantly different from that in normal rats. The lack of significant inhibition of phenobarbital-potentiated hepatotoxicity by both polyethylene glycol-superoxide dismutase and methyl palmitate suggests that reactive oxygen species released from a non-parenchymal source are not as crucial to the hepatotoxicity of ortho-dichlorobenzene in phenobarbital-pretreated as in the normal rats. The results suggest that reactive oxygen species released from Kupffer cells play a major role in the progression of orthodichlorobenzene hepatotoxicity.

環境中動態TERRESTRIAL FATE: Based on a recommended classification scheme(1), Koc values of 280(2) and 320(3) measured in soil, indicates that 1,2-dichlorobenzene is expected to have moderate mobility in soil(SRC). Volatilization of 1,2-dichlorobenzene is expected from moist soil surfaces given its Henry's Law constant of 1.5X10-3 atm-cu m/mole at 20 °C(4). Volatilization of 1,2-dichlorobenzene from dry soil surfaces is expected based on a vapor pressure of 1.4 mm Hg at 25 °C(5). The volatilization half-life of 1,2-dichlorobenzene from Captina and McLaurin sandy loam soils was measured as about 4 days(6). 1,2-Dichlorobenzene at 100 mg/L achieved 0% of its theoretical BOD using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(7), suggesting that biodegradation is expected to be slow in soil(SRC). 1,2-Dichlorobenzene is resistant to biodegradation in soils, with half-lives expected to be greater than 9 months(8).AQUATIC FATE: Based on a recommended classification scheme(1), log Koc values of 3.7(2) and 4.3(3) measured in sediment indicate that 1,2-dichlorobenzene is expected to adsorb to suspended solids and sediment in water(SRC). 1,2-Dichlorobenzene is expected to volatilize from water surfaces(4) given its Henry's Law constant of 1.5X10-3 atm-cu m/mole at 20 °C(5). Using this Henry's Law constant and an estimation method(4), estimated volatilization half-lives for a model river and model lake are 4 and 120 hours, respectively(SRC). According to a classification scheme(6), BCF values in the range of 90 to 560, measured in carp(7) and trout(8), suggest that bioconcentration in aquatic organisms is moderate to high. 1,2-Dichlorobenzene at 100 mg/L achieved 0% of its theoretical BOD using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(7), suggesting that biodegradation is expected to be slow in water under aerobic conditions(SRC). The biodegradation half-life of 1,2-dichlorobenzene in an acclimated anaerobic sediment slurry obtained from the Tsurumi River, Japan was 37 days(9).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1,2-dichlorobenzene, which has a vapor pressure of 1.4 mm Hg at 25 °C(2), is expected to exist in the vapor phase in the ambient atmosphere. Vapor-phase 1,2-dichlorobenzene 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 about 38 days(SRC), calculated from its rate constant of 4.2X10-13 cu cm/molecule-sec (3). 1,2-Dichlorobenzene does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to undergo direct photolysis by sunlight(4).

毒性の概要... 1,2-Dichlorobenzene has been shown to cause eye and respiratory irritation in humans at exposure levels above 100 ppm. Skin irritation has been observed following dermal application in humans and animals. 1,2-Dichlorobenzene is absorbed via the oral route. Absorption via the dermal or inhalation routes is poorly characterized. Inhalation is expected to be the major route for human exposure. The available toxicological data indicate that metabolic profiles and effects from 1,2-dichlorobenzene exposure are similar in rats, mice and humans. Animal studies with rats and mice have shown 1,2-dichlorobenzene to induce acute hepatotoxic effects. The LD50 for a single oral exposure to 1,2-dichlorobenzene for the rat ranges from 1516 to 2138 mg/kg bw. The LC100 for the rat is </= 977 ppm (5.9 mg/L) for a 10 hour exposure. During a 4 hour exposure, 1 of 20 rats died at 941 ppm (5.6 mg/L). In humans, the acute effects of 1,2-dichlorobenzene by ingestion or inhalation are reported to be headache, nausea, vomiting, vertigo, malaise and unconsciousness. Several oral studies of rats and mice ranging from 10 days to 2 years duration indicate that the adverse effects include increases in liver and kidney weights and hepatotoxicity. From these repeat dose studies, the NOAEL for non-neoplastic effects was 60 mg/kg bw, while the LOAEL was 120 mg/kg bw due to increased renal tubular regeneration in male mice. In several microbial organisms and mammalian systems, 1,2-dichlorobenzene tested negative in vitro. However, it did induce sister chromatid exchanges in Chinese Hamster ovary cells and increased mutation frequency in mouse lymphoma cells, both in the presence of metabolic activation. 1,2-dichlorobenzene was negative in several in vivo mammalian tests, except one of two micronuclei assays in mouse bone marrow was positive. In a two-year oral study in rats and mice, 1,2-dichlorobenzene was considered not to be carcinogenic (maximum dose of 120 mg/kg bw). In an inhalation 2-generation reproduction study in rats, no fertility effects were observed and reduced pup weight during lactation occurred at doses toxic to adults. The NOAEL and LOAEL (kidney and liver effects) for adult rats were 50 (0.3 mg/L) and 150 ppm (0.6 mg/L) respectively. In developmental studies in rats and rabbits, developmental effects were only seen in rats at maternally toxic doses (400 ppm, 2.4 mg/L). No human epidemiological studies have been conducted. ... 1,2-Dichlorobenzene has been tested on a wide range of aquatic organisms under acute exposure, although chronic data are scarce. Results for fish ranged from 96 hr LC50=1.58 mg/L for rainbow trout to 57 mg/L for fathead minnow. Both acute and chronic toxicity to aquatic invertebrates were obtained with two results showing high acute toxicity, namely EC50's of 0.78 mg/L and 0.66 mg/L to Daphnia and Ceriodaphnia respectively. Results from exposure to algae showed EC50 values in the 1-100 mg/L range for 1,2-dichlorobenzene. Toxicity to microorganisms can be considered slight. Although the major compartment expected to be exposed to 1,2-dichlorobenzene is the atmosphere, there are no ecotoxicity results available for organisms exposed through the gas phase. The chlorine substituents on the chemical suggest a potential for effects on stratospheric ozone. However, the chemical is unlikely to persist long enough to escape the troposphere, although it may persist long enough to undergo long range atmospheric transport. While there are a large number of acute data covering all trophic levels, chronic data are scarce. Therefore, an assessment factor of 100 has been chosen. The result used for determining the PNEC was the lowest chronic value obtained, i.e. 21 d NOEC = 0.63 mg/L for Daphnia magna. The PNECaquatic was therefore determined to be 6.3 ug/L.1,2-DCB was found to covalently bind to DNA, RNA, and proteins of liver, kidney, lung, and stomach. (L395)
RCRA 要件F002When 1,2-dichlorobenzene is a spent solvent, it is classified as a hazardous waste from a nonspecific source (F002), as stated in 40 CFR 261.31, and must be managed according to state and/or federal hazardous waste regulations.U070As stipulated in 40 CFR 261.33, when 1,2-dichlorobenzene, 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).

FIFRA 要件As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. 1,2-Dichlorobenzene is found on List C. Case No: 3057Pesticide type: AntimicrobialCase Status: No products containing the pesticide are actively registered ... The case /is characterized/ as "cancelled." Under FIFRA, pesticide producers may voluntarily cancel their registered products. EPA also may cancel pesticide registrations if registrants fail to pay required fees or make/meet certain reregistration commitments, or if EPA reaches findings of unreasonable adverse effects.Active ingredient (AI): 1,2-DichlorobenzeneAI Status: The active ingredient is no longer contained in any registered pesticide products ... "cancelled."
