環境中動態TERRESTRIAL FATE: Based on a classification scheme(1), measured Koc values of 390 to 393(2,3), indicate that 3,4-dichloronitrobenzene is expected to have moderate mobility in soil(SRC). Volatilization of 3,4-dichloronitrobenzene from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 8.07X10-6 atm-cu m/mole(4). 3,4-Dichloronitrobenzene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.03X10-2 mm Hg(5). Lack of biodegradation of 3,4-dichloronitrobenzene incubated in an aquifer slurry over an unspecified time frame(6) suggests that biodegradation is not an important environmental fate process in soil(SRC). However, under anaerobic conditions using a river sediment, a half-life of 2.4 days has been reported(7).AQUATIC FATE: Based on a classification scheme(1), measured Koc values of 390 to 393 in silt loams(2,3), indicate that 3,4-dichloronitrobenzene is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(4) based upon a Henry's Law constant of 8.07X10-6 atm-cu m/mole(5). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 6 days and 51 days, respectively(SRC). According to a classification scheme(6), a BCF values ranging from 104 to 130(7,8) suggest the potential for bioconcentration in aquatic organisms is high(SRC). Lack of biodegradation of 3,4-dichloronitrobenzene incubated in an aquifer slurry over an unspecified time frame(9) suggests that biodegradation is not an important environmental fate process in water(SRC). However, under anaerobic conditions using a river sediment, a half-life of 2.4 days has been reported(10).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 3,4-dichloronitrobenzene, which has a /an estimated vapor pressure of 1.03X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 3,4-dichloronitrobenzene 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 321 days(SRC), calculated from its rate constant of 5.0X10-14 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). 3,4-Dichloronitrobenzene contains chromophores that absorb at wavelengths >290 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC).
有害作用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.
暴露経路The substance can be absorbed into the body by ingestion.
毒性の概要Human Health: 1,2-Dichloro-4-nitrobenzene is absorbed from the gastro-intestinal tract and although there are some species differences in experimental animals from the available data it can be concluded that 1,2-dichloro-4-nitrobenzene is excreted mainly via urine in the form of the mercapturic acid derivative N-acetyl-S-(2-chloro-4-nitrophenyl)-Lcysteine. ... Based on the results of the acute dermal toxicity study with rats the LD50 is > 2000 mg/kg bw. From studies with rabbits no LD50 could be derived, the lowest Lethal Dose Level (LDLo) was 950 mg/kg bw. The acute oral toxicity in rats ranges from 625 to 950 mg/kg bw. 1,2-Dichloro-4- nitrobenzene causes the formation of methemoglobin. ... 1,2-Dichloro-4-nitrobenzene gave no skin irritation effects when tested for 4 hours under semiocclusive conditions ... and showed slightly irritating effects, which disappeared within 72 hours under occlusive conditions ... 1,2-Dichloro-4-nitrobenzene is slightly irritating to the eyes /but/ ... was not found to induce dermal sensitization ... . In addition, 1,2-dichloro-4-nitrobenzene was not found to induce dermal sensitization in humans in a limited study. The main targets identified in animal studies after repeated oral administration as well as after inhalation exposure are the hematological system and in addition the kidneys after oral application and the liver after inhalation. From a 28- day oral study ... a NOAEL of 4 mg/kg bw/day was derived. The NOAEL following subchronic inhalation exposure study of limited validity (limited documentation) was 0.4 mg/cu m (4 hours per day). Changes in hematological parameters (e.g. methemoglobinaemia, Heinz bodies) are the main target in the only available report on exposure of workers. As these findings relate to mixed exposures they cannot be clearly attributed to 1,2-dichloro-4-nitrobenzene, but would be plausible, because they were also observed in animal experiments. In the recent open literature reports of human poisoning could not be identified. 1,2-Dichloro-4-nitrobenzene exhibits mutagenic activity in Salmonella typhimurium but not in the HPRT test in Chinese Hamster Ovary (CHO) cells. 1,2-Dichloro-4-nitrobenzene induced chromosomal aberrations in V79 cells with metabolic activation only at the highest concentration, which was cytotoxic. In insects (Drosophila melanogaster) 1,2-dichloro-4-nitrobenzene revealed no mutagenic activity in the SLRL-test after application over 3 days with slight increased toxicity, but revealed mutagenic activity following a single ip injection of a clearly toxic dose. 1,2-Dichloro-4-nitrobenzene showed no clastogenic activity in vivo in a chromosomal aberrations test with rats. Overall in non-toxic doses, there was no evidence for genotoxicity in vivo under the conditions tested. Studies dealing specifically with toxicity to reproduction were not identified. The subacute study with 1,2-dichloro-4- nitrobenzene yielded no damage of the reproductive organs in rats despite clear systemic toxicity up to the maximum tolerated dose of 100 mg/kg bw. 1,2-Dichloro-4-nitrobenzene commercial grade (85% 1,2-dichloro-4-nitrobenzene and 15% 1,2-dichloro-3- nitrobenzene) caused effects on development at maternally toxic doses probably due to methemoglobinemia in dams and fetuses. A significant dose-response trend for variations (dilated ureters) was seen in the fetuses of the >= 30 mg/kg bw/day-groups and significant reduced body weight gain of dams at dose levels of 30 mg/kg bw/day on gd 6-10 with an even stronger effect at 100 mg/kg bw/day. Thus, 10 mg/kg bw/day was determined as the NOAEL for maternal and developmental toxicity. Environment: ... Concerning the acute toxicity of 1.2-dichloro-4-nitrobenzene towards aquatic species reliable experimental results of tests with fish, Daphnia, and algae are available. The acute toxicity determined for fish (Leuciscus idus) was of 3.1 mg/L (48 hr LC50) ... and Daphnia (Daphnia magna) of 3 mg/L (24 hr-EC50) ... . In the growth inhibition test with algae (Scenedesmus obliquus) the value 5.8 mg/L was achieved after 48 hr (48 hr-ErC50)... . For the algae Chlorella fusca a value of 0.32 mg/L was found after 24 hr (24 hr-ErC50). In a chronic (21 d) study with Daphnia magna a NOEC of 0.025 mg/L was determined for the most sensitive endpoint reproduction rate. An ErC10 > 0.1 mg/L was reported for the algae Scenedesmus subspicatus after 48 hours. For terrestrial organisms the lowest measured 6d-EC50 was 27 mg/L for the plant Phaseolus aureus. Applying an assessment factor of 50 to the lowest available chronic value of 25 ug/L (21d reproduction in D. magna), a PNECaqua of 0.5 ug/lL is obtained.
生態毒性抜粋/AQUATIC SPECIES/ In a reproduction (21 d) study with Daphnia magna performed in a semistatic system in closed vessels /the authors/ found a NOEC of 0.025 mg/L for the most sensitive endpoint reproduction rate. The stability of the test substance concentration was confirmed by analytical monitoring.

ICSC Environmental DataThe substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment.
Soil Adsorption/MobilityAn experimentally determined mean Koc value of 393 for 3,4-dichloronitrobenzene was reported using 4 silt loam soils(1). A log Koc value of 2.62 was reported following adsorption studies using sediment from the Yangste River in China(2), corresponding to a Koc of 390(SRC). According to a classification scheme(3), these Koc values suggest that 3,4-dichloronitrobenzene is expected to have moderate mobility in soil. Using a modified organo montmorillonite clay from Jiangning Jinagsu Province, China, a log Koc of 3.76 was determined(3), corresponding to a Koc of 5,754(SRC).

製法・合成法

調製方法

Nitration of 1,2-dichlorobenzene with mixed acid at 35 – 60 ℃ results in a mixture of 3-nitro (10 %) and 4-nitro (90 %) isomers, which are separated by crystallization. A more expensive process (two stages from chlorobenzene) is based on chlorination of molten 4-chloronitrobenzene (90 – 100 ℃) by a process similar to that used for 3- chloronitrobenzene production. Chlorination has the advantage of giving a pure product, but it cannot be used if the isomeric 1,2-dichloro-3-nitrobenzene is also required.
