Methods and materials for containment and cleaning up
1. Remove all ignition sources. 2. Ventilate area of spill or leak. 3. For small quant, sweep onto paper or other suitable material, place in an appropriate container and burn in a safe place (such as a fume hood). Large quant may be reclaimed; however, if this is not practical, use a procedure similar to that for small quant. Terphenyls

Persistence and degradability
A waste water mixture containing 33% m-terphenyl, 17% o-terphenyl, and 1.5% thermip (a heat exchanger consisting of naphthalene, methyl naphthalene diphenyl, and alkyl derivatives of naphthalene) was inoculated with a mixture of three bacteria, two Pseudomonas and one Acinetobacter species. After 130 hours aerobic incubation, 100% of the o-terphenyl remained(1).
Bioaccumulative potential
A BCF of 590 for o-terphenyl was measured in goldfish(1). An estimated BCF value of 550 was calculated for o-terphenyl(SRC), using a measured water solubility of 1.24 mg/l(2) and a recommended regression-derived equation(3). According to a recommended classification scheme(4), these BCF values indicate that bioconcentration of o-terphenyl in aquatic organisms should be an important fate process(SRC).
Mobility in soil
The Koc of o-terphenyl is estimated as approximately 3900(SRC), using an experimental water solubility of 1.24 mg/l(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that o-terphenyl has only slight 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.
