ABSTRACT
Soluble in most solvents (U.S. EPA, 1985). Solubility in water (µg/L): 420 (shake flask-GLC, Paris et al., 1978) 49 at 24 °C (shake flask-nephelometry, Hollifield, 1979) 906 at 23 °C (Lee et al., 1979) Vapor pressure (mmHg): 9.03 x 10-4 at 25 °C (estimated using GC retention data, Foreman and Bidleman, 1985) Environmental fate: Biological. Reported degradation products by the microorganism Alcaligenes BM-2 for a mixture of polychlorinated biphenyls include monohydroxychlorobiphenyl, 2-hydroxy-6oxochlorophenylhexa-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). Exposure limits: Potential occupational carcinogen. NIOSH REL: TWA 1.0 µg/m3, IDLH 5 mg/m3. Toxicity: LC50 (96-h) for Pteronarcella badia 610 µg/L, Atlantic salmon 134 µg/L, bluegill sunfish 460 µg/L, brown trout 138 µg/L, brook trout >800 µg/L, channel catfish 440 µg/L, lake trout 480 µg/L, longnose sucker 330 µg/L, rainbow trout 135 µg/L, white sucker 435 µg/L, yellow perch 240 µg/L (Johnson and Finley, 1980). A teratogen having a low toxicity (Patnaik, 1992). Drinking water standard (final): For all PCBs, the MCLG and MCL are zero and 0.5 µg/L, respectively (U.S. EPA, 2000). Uses: 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).
