Viscous, oily, light yellow to pale yellow-brown liquid or white powder with a weak, characteristic odor

Insulator fluid for electric condensers; additive in high pressure lubricants. In fluorescent and high-intensity discharge ballasts manufactured prior to 1979 (U.S. EPA, 1998).
At a concentration of 5 to 25 wt %, increased the effective kill-life of the lindane spray up to 10 times. May have been used in chlordane and BHC insecticide formulations (Monsanto, 1960).

Viscous oily liquid.

Insoluble in water.

Simple aromatic halogenated organic compounds are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms.

ACUTE/CHRONIC HAZARDS: Toxic irritant. Hazardous decomposition products.

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.

Biological. Reported degradation products by the microorganism Alcaligenes BM-2 for a mixture of polychlorinated biphenyls include monohydroxychlorobiphenyl, 2-hydroxy-6- oxochlorophenylhexa-2,4-dieonic acid, chlorobenzoic acid, chlorobenzoylpropionic acid, chlorophenylacetic acid, and 3-chlorophenyl-2-chloropropenic acid (Yagi and Sudo, 1980). When PCB-1016 was statically incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum, no significant biodegradation was observed. At a concentration of 5 mg/L, percent losses after 7, 14, 21, and 28-d incubation periods were 44, 47, 46, and 48, respectively. At a concentration of 10 mg/L, only 22, 46, 20, and 13% losses were observed after the 7, 14, 21, and 28-d incubation periods, respectively (Tabak et al., 1981).
Chemical/Physical. PCB-1016 will not hydrolyze to any reasonable extent (Kollig, 1993).
