Reproductive toxicityOne human study reported abnormal physical development in young children who ingested contaminated bread during a 4-year poisoning incident. Hexachlorobenzene has been found to decrease the survival rates of newborn animals and to cross the placenta and accumulate in fetal tissue in several animal species. Neurological, teratogenic, liver, and immune system effects have been reported in the offspring of animals orally exposed to hexachlorobenzene while they were pregnant.

12.Ecological information 12.1 Toxicity- Toxicity to fish: LC50; Species: Pimephales promelas (fathead minnow) weight 0.7 g; Conditions: static bioassay, 20°C; Concentration: 22 mg/L for 96 hr @ 20°C (95% confidence limit) /technical 80-96%
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Little to no biodegradation was noted in biodegradation screening tests(1,3,4), in activated sludge(2,5), or in soil(6-8). Measurement of CO2 evolution from suspended soil cultures over a 14-day incubation period were as follows: 0.4% under aerobic conditions, 0.2% under anaerobic conditions(9).
12.3 Bioaccumulative potentialBCF values of 2,700 to 4,800 were measured in carp exposed to 10 ug/L of hexachlorobenzene during an 8 week incubation period and BCF values of 1,600 to 3,900 were measured in carp exposed to 1 ug/L of hexachlorobenzene during an 8 week incubation period(1). Log BCF values in rainbow trout (Salmo gairdneri) were given as 3.7-4.3(2-4) and in fathead minnows (Pimephales promelas) and sunfish (Lepomis cyanellus) log BCF values of 4.21 and 4.34, respectively, were reported(3). After an 8-week exposure period of carp (Cyprinus carpio) to concentrations of 0.5 and 0.05 ug/L of hexachlorobenzene, the BCFs were 11,000-27,000 and 6,000-30,000, respectively(5). According to a classification scheme(6), these BCF values suggest that bioconcentration in aquatic organisms is very high, provided the compound is not metabolized by the organism(SRC).
12.4 Mobility in soilA log Koc value of 5.5 (Koc of 3.2X10+5) was reported for hexachlorobenzene in freshwater river sediment(1). A log Koc value of 4.9 (Koc of 7.9X10+4) was reported for hexachlorobenzene in sediment obtained from the Ise Bay, Japan(2). Measured log Koc values of 3.6 (Koc of 4X10+3)(3) and 4.0 (Koc of 1X10+4)(4) were reported in soils. Log Koc values of 6.42 and 5.56 (Koc values of 2.6X10+6 and 3.6X10+5) were determined for two sediment layers from a lake(5). Hexachlorobenzene has measured log Koc value of 3.99 (Koc of 9.8X10+3) reported for soils(6). Hexachlorobenzene was found to desorb very slowly from sediment in water(7). According to a recommended classification scheme(8), these Koc values suggest that hexachlorobenzene is expected to be immobile in soil(SRC).

13.Disposal considerations 13.1 Disposal methods ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packagingContainers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
