Environmental precautions
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment.
Methods and materials for containment and cleaning up
Environmental considerations: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash or cement powder. Apply "universal" gelling agent to immobilize spill. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ /o-Dichlorobenzene/ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. p-Dichlorobenzene

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Oryzias latipes - 5.7 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 1.2 mg/L - 48 h.
- Toxicity to algae: ErC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 9.2 mg/L - 72 h.
- Toxicity to microorganisms: EC50 - Tetrahymena pyriformis - 130 mg/L - 24 h.
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).
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.
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).
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.
