  • Health Effects: Prolonged exposure to high concentration of 1,4-DCB may cause weakness, dizziness, loss of weight, liver injury. Chronic (months to years) ingestion of 1,4-DCB products can provoque skin blotches and problems with red blood cells, such as anemia. There is an indication that 1,4-DCB can affect the development of the nervous system after birth. 1,4-DCB is possibly a human carcinogen. (L395, T63) Source: Toxin and Toxin Target Database (T3DB)
  • NFPA Health Rating: 2 - Materials that, under emergency conditions, can cause temporary incapacitation or residual injury. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Fire Rating: 2 - Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air.

  • NFPA Instability Rating: 0 - Materials that in themselves are normally stable, even under fire conditions. Source: Hazardous Substances Data Bank (HSDB)
  • Toxicity Summary: IDENTIFICATION AND USE: 1,4-Dichlorobenzene (p-DCB) is a solid. It is used as moth repellent, general insecticide, germicide, space odorant, in manufacture of 2,5-dichloroaniline, dyes, intermediates, pharmacy, agriculture (fumigating soil). HUMAN STUDIES: Fumes from the surface of hot p-DCB may irritate skin slightly when contact is repeated or prolonged. Leukoencephalopathy has been described following ingestion of p-DCB mothballs. Hemolytic anemia and methemoglobinemia is more rarely reported in such cases. p-DCB increased the frequency of sister chromatid exchange in human peripheral blood lymphocytes in the absence of metabolic activation. ANIMAL STUDIES: p-DCB induces renal tumors specifically in male rats through an alpha2u-globulin-associated response. p-DCB failed to exhibit genotoxic effects in vivo, exhibiting negative responses in unscheduled DNA synthesis, in the chromosome aberration assay, in the dominant lethal assay, and in the in vivo micronucleus assay. It was reported as positive in one DNA strand breakage assay and in one in vivo micronucleus assay. p-DCB bound to DNA in the liver, lung, and kidney of mice but not in that of male rats. It also induced DNA damag Source: Hazardous Substances Data Bank (HSDB)
  • Toxicity Summary: The hepatotoxicity and nephrotoxicity observed in laboratory animals are likely due to the formation of toxic intermediates formed while converting 1,4-DCB to 2,5-dichlorophenol by cytochrome P-450, or by depletion of GSH at higher doses of 1,4-DCB, or both. (L395) Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Bioconcentration: A mean BCF value of 78 was measured in mosquito fish exposed to 57-233 ug/L of 1,4-dichlorobenzene during 1 to 4 day incubation periods(1). Mean BCF values of 370 to 720 were experimentally determined for rainbow trout exposed to unspecified concentrations of 1,4-dichlorobenzene up to 119 days in laboratory aquariums(2). A whole body BCF of 60 was determined for bluegill sunfish exposed to 1,4-dichlorobenzene over a 28-day period in a continuous flow system(3). BCF values of 33 to 73 were measured in carp exposed to 2 ug/L of 1,4-dichlorobenzene during an 35 day incubation period and BCF values of 47 to 190 were measured in carp exposed to 0.2 ug/L of 1,4-dichlorobenzene during a 35 day incubation period(4). According to a classification scheme(5), these BCF values suggest that bioconcentration in aquatic organisms is moderate to high(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of 273(2) and 390(3) indicate that 1,4-dichlorobenzene is expected to have moderate mobility in soil(SRC). Volatilization of 1,4-dichlorobenzene from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 2.41X10-3 atm-cu m/mole(4). 1,4-Dichlorobenzene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.74 mm Hg at 25 °C(5). Utilizing the Japanese MITI test, 0% of the Theoretical BOD was reached in 4 weeks(6) indicating that biodegradation is not an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), Koc values of 273(2) and 290(3) indicate that 1,4-dichlorobenzene 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 2.41X10-3 atm-cu m/mole(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 4 hours and 5 days, respectively(SRC). According to a classification scheme(6), BCF values ranging from 33-720(7-10) suggest the potential for bioconcentration in aquatic organisms is moderate to high(SRC). Utilizing the Japanese MITI test, 0% of the Theoretical BOD was reached in 4 weeks(10) indicating that biodegradation is not an important environmental fate process in water(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1,4-dichlorobenzene, which has a vapor pressure of 1.7 mm Hg at 25 °C(2), is expected to exist solely in the vapor phase in the ambient atmosphere. Vapor-phase 1,4-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 40 days(SRC), calculated from its rate constant of 3.2X10-13 cu cm/molecule-sec at 25 deg(3). 1,4-Dichlorobenzene does not contain chromophores that absorb at wavelengths >290 nm and, therefore, is not expected to undergo direct photolysis by sunlight(4).

  • Uses: Para-Dichlorobenzene is limited to indoor use only. It is used as a moth and beetle repellant in products which are applied to commercial and residential use sites such as closets and storage containers, and to repel lice and mites from bird cages. It is also used in empty bee supers (stored indoors), to repel wax moths. When formulated into varpal rope, it is used in attics to repel snakes, mice, rats, squirrels, and bats.

  • Uses: 1,4-DCB is used a pesticide and a deodorant, most famously in mothballs in which it is a replacement for the more traditional naphthalene. 1,4-DCB is also used as a precursor in the production of the polymer poly(p-phenylene sulfide). 1,4-DCB also is used to make deodorant blocks used in garbage cans and restrooms, and to help control odors in animal-holding facilities. 1,4-DCB has been used as an insecticide on fruit and as an agent to control mold and mildew growth on tobacco seeds, leather, and some fabrics. Recently, using 1,4-DCB to make resins has become very important. Exposure may result from breathing vapors from 1,4-DCB products, drinking contaminated water or eating contaminated food (However, the levels of p-DCB in foods are generally low), and eye exposure.
