Most important symptoms/effects, acute and delayed
Chronic inhalation of mist or vapors may result in damage to lungs, liver, and kidneys. Acute vapor exposure can cause symptoms ranging from coughing to central nervous system depression and transient anesthesia. Irritating to skin, eyes, and mucous membranes. May cause dermatitis. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Lindane and related compounds

- Toxicity to microorganisms: IC50 - Nitrosomonas sp. - 47 mg/L - 24 h.
Persistence and degradability
AEROBIC: 1,2-Dichlorobenzene at 100 mg/L achieved 0% of its theoretical BOD using an activated sludge inoculum at 30 mg/L over a 4 week incubation period in the Japanese MITI test(1). 1,2-Dichlorobenzene was resistant to biodegradation in another Japanese MITI test study(2). Dichlorobenzene isomers were slowly biodegraded (6.3% of theoretical CO2 evolution in 10 weeks) in an alkaline soil sample(3). The rate constant for 1,2-dichlorobenzene in a heterogeneous aquifer at the Columbus Air Force Base, Mississippi was 0.0059 days-1, corresponding to a biodegradation half-life of about 117 days(4). 1,2-Dichlorobenzene is resistant to biodegradation in soils, with half-lives expected to be greater than 9 months(5).
Bioaccumulative potential
The sorption of 8 organic compounds by a representative green alga, Selenastrum capricornutum, was determined by GLC by a series of linear model experiments. The log10 bioconcentration factors (BCF), defined as the ratio of the concentration on/in the algae to the concentration in the aqueous medium, were as follows: benzene 3.32, toluene 3.18, chlorobenzene 3.69, 1,2-dichlorobenzene 4.17. The relation of log10 BCF correlation with log10 octanol-water partition coefficient (P) was determined to be log10 BCF= 0.46 log10 P + 2.36.
Mobility in soil
Experimental Koc values of 280(1) and 320(2) were determined for 1,2-dichlorobenzene in silt loam soils. A log Koc value of 3.7 was reported for 1,2-dichlorobenzene in sediment obtained from the Ise Bay, Japan(3) and a log Koc value of 4.3 was measured from sediment of Lake Ketelmeer, Netherlands(4). According to a recommended classification scheme(5), these soil Koc values suggest that 1,2-dichlorobenzene has moderate mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The 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.
Containers 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.
