Rinse mouth. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
INHALATION: Causes headache, drousiness, unsteadiness. Irritating to mucous membranes. EYES: Severe irritation. SKIN: Severe irritation. INGESTION: Irritation of gastric mucosa, nausea, vomiting, diarrhea, abdominal cramps and cyanosis. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
/SRP:/ 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/

12.2 Persistence and degradability
AEROBIC: 1,3-Dichlorobenzene at 100 mg/L exhibited 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). Dichlorobenzene isomers were slowly biodegraded (6.3% of theoretical CO2 evolution in 10 weeks) in an alkaline soil sample(2).
12.3 Bioaccumulative potential
BCF values of 60 to 230 were measured in carp exposed to 100 ug/L of 1,3-dichlorobenzene during an 8 week incubation period and BCF values of 60 to 370 were measured in carp exposed to 10 ug/L of 1,3-dichlorobenzene during an 8 week incubation period(1). Mean 1,3-dichlorobenzene BCF values of 420 to 740 were experimentally determined for rainbow trout exposed up to 119 days in laboratory aquaria(2). A whole body BCF of 90 was determined for bluegill sunfish exposed to 1,3-dichlorobenzene over a 28-day period in a continuous flow system(3). According to a classification scheme(4), these BCF values suggest that bioconcentration in aquatic organisms is moderate to high.
12.4 Mobility in soil
An experimental Koc value of 300(1) was determined for 1,3-dichlorobenzene in silt loam soil. According to a recommended classification scheme(3), these Koc values suggest that 1,3-dichlorobenzene has moderate to low mobility in soil. A log Koc value of 3.5 was reported for 1,3-dichlorobenzene in sediment obtained from the Ise Bay, Japan(2) and a log Koc value of 4.7 was measured from sediment of Lake Ketelmeer, Netherlands(4).
