4.2 Most important symptoms/effects, acute and delayedACUTE/CHRONIC HAZARDS: This compound may cause irritation of the skin.
4.3 Indication of immediate medical attention and special treatment needed, if necessary Absorption, Distribution and ExcretionThree tetrachlorobenzene (TCB) congeners (1,2,3,4- 1,2,3,5- and 1,2,4,5-tetrachlorobenzene) were administered daily by gavage to pregnant Sprague-Dawley rats at levels of 50, 100, or 200 mg/kg from day 6-15 of gestation. Residues of all three congeners were found in maternal and fetal tissues but generally the amounts of the 1,2,4,5- isomer were about 100 times higher than the other two.

10.2 Chemical stabilityStable under recommended storage conditions.
10.3 Possibility of hazardous reactionsSimple aromatic halogenated organic compounds, such as 1,2,3,4-TETRACHLOROBENZENE, are very unreactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

A 0% theoretical BOD in sludge over a 4 week incubation period suggests that biodegradation of 1,2,3,4-tetrachlorobenzene will be slow(1). 1,2,3,4-Tetrachlorobenzene was biodegraded by an acclimated anaerobic sediment slurry obtained from the Tsurumi River, Japan(2). The first-order biodegradation rate constant was 0.038 days-1, corresponding to a half-life of about 18 days(2). The half-life of 1,2,3,4-tetrachlorobenzene in sewage sludge amended soil was 34.5 days(3). An enriched microbial culture derived from sediment of the Rhine River reductively dechlorinated 1,2,3,4-tetrachlorobenzene to 1,2,4-trichlorobenzene in 280 days after a lag period of 47 days(4).
12.3 Bioaccumulative potentialBCF values of 520 to 1,560 were measured in carp exposed to 10 ug/l of 1,2,3,4-tetrachlorobenzene during a 6 week incubation period and BCF values of 490 to 1,700 were measured in carp exposed to 1 ug/l of 1,2,3,4-tetrachlorobenzene during a 6 week incubation period(1). Mean log BCF values of 3.7-4.1 were measured for rainbow trout exposed to 1,2,3,4-tetrachlorobenzene(2). A mean log BCF value of 3.5 was measured in fathead minnows exposed to 1,2,3,4-tetrachlorobenzene for 2-120 hours(3). A mean BCF value of 5,200 was reported for rainbow trout exposed to low levels of 1,2,3,4-tetrachlorobenzene for 119 days and a mean BCF value of 12,000 was reported for rainbow trout exposed to high concns of 1,2,3,4-tetrachlorobenzene for 119 days(4). According to a classification scheme(5), these BCF values suggest that bioconcentration in aquatic organisms is high.
12.4 Mobility in soilA log Koc value of 3.8(1) was reported for 1,2,3,4-tetrachlorobenzene in soils and log Koc values of 3.5 to 3.8 were reported in sandy and clay loams(2). A log Koc value of 4.4 was reported for 1,2,3,4-tetrachlorobenzene in sediment obtained from Ise Bay, Japan(3) and a log Koc value of 4.7 was reported from sediment of Lake Oostvaardersplassen, Netherlands(4). According to a recommended classification scheme(5), these Koc values suggest that 1,2,3,4-tetrachlorobenzene has low mobility in soil.

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.
