polyvinyl chloride

 
a tasteless, odorless, clear hard resin with many industrial uses, including as packaging, clothing, and insulation of pipes and wires. Workers in its manufacture are at risk primarily because of the toxicity of its parent compound, vinyl chloride. Excessive inhalation of its dust can cause pneumoconiosis.

pol·y·vi·nyl chlo·ride (PVC),

(pol'ē-vī'nil klōr'īd),
A polymer plastic used as a rubber substitute in many industrial applications; suspected of being carcinogenic in humans.

polyvinyl chloride

PVC  Toxicology A toxin that causes interstitial lung disease due to bis(2)-ethyhexylphthalate–DEHP, an agent for 'plasticizing' vinyl chloride polymers, with narcotic effects, and causes acroosteolysis, hepatitis, soft-tissue changes, Raynaud phenomena, hepatic hemangiosarcoma–with as little as 250 ppm, brain tumors, poorly differentiated large cell CAs and adenoCA of lungs. Cf PCB, Plasticizer, Toxic dump.
