The document presents background information used in developing advisory levels of PCBs in soil estimated to be permissible in protecting public health. The results of exposure assessment and health effects studies are combined to arrive at the permissible levels of PCBs. Health effects studies conducted using animals for the duration of 10-30 days are used to determine the 10-day advisory levels for PCB clean-up. The long-term advisory levels are based on the carcinogenic risk evaluations.
