Historical long-term exposure to pentachlorophenol causing risk of cancer--a community study.

Background: Pervious studies suggested occupational workers exposure to pentachlorophenol (PCP) might contribute to increased risk of cancer. However, few studies have focused on associations between PCP and cancer risk at the community level.

Objective: The present study was to explore the cancer risk for the community population living long-term in a PCP contaminated area.
