RoC Review of Pentachlorophenol and By-products of its Synthesis (PCP)
Listing Status: Reasonably anticipated to be a human carcinogen
Profile: Pentachlorophenol and By-products of Its Synthesis (217KB)
Fact Sheet: Pentachlorophenol and By-Products of Its Synthesis (187KB)
Primary Uses or Exposures
- A complex mixture of chemicals primarily used as wood preservatives. The mixture includes pentachlorophenol and additional chlorinated molecules (particularly chlorinated dibenzo-p-dioxins and dibenzofurans) that are formed as by-products because of the elevated temperatures and pressures used in the production processes.
- Currently used for the treatment of utility poles, cross arms, wooden pilings (e.g., wharf pilings), fence posts, and lumber or timbers for construction. In the past (prior to 1984) it also was used as a biocide and was found in ropes, paints, adhesives, leather, canvas, insulation, and brick walls.
- People are exposed to PCP in workplaces (via inhalation or through the skin) that produce PCP (past) or use treated wood.
- In their everyday lives, people can be exposed to PCP from the environment by breathing contaminated outdoor or indoor air or indoor dust, from the soil, and by ingesting water or food.
