Biphenyl toxicity
WebDioxins, a collective term for a group of environmental contaminants that includes certain dioxin, furan, and dioxin-like PCB (polychlorinated biphenyl) congeners, are found throughout the world. WebCarefully observe patients with inhalation exposure for any systemic signs or symptoms of toxicity and administer treatment as necessary. No specific measures are available to reduce respiratory tract absorption. In the rare event of ingestion of PCBs, emesis would be contraindicated because of the high risk of aspiration.

Webcomplication in toxicity assessment is that noncancer toxicity can result from relatively low dose levels. For example, all doses of Aroclor 1016 predicting a cancer risk above 5E-6 are also associated with an unacceptable noncancer hazard. Another consideration for toxicity assessment is the dioxin-like activity of co-planer PCBs.
