Short description and topics:
EXTRACT:
The purpose of this guidance is two-fold:
1. To recommend the use of PRGs to protect against cancer and non-cancer effects
associated with human exposure to dioxin in soil at CERCLA and RCRA sites,
and,
2. To discuss the interim use of these recommended PRGs for soil at CERCLA and
RCRA sites
These draft recommended interim PRGs are intended for use in evaluating dioxin
(2,3,7,8-tetrachlorodibenzo-p-dioxin, TCDD) and other dioxin-like compounds in soil.
Dioxin-like compounds, including other polychlorinated dibenzodioxins (PCDDs),
dibenzofurans (PCDFs) and biphenyls (PCBs) may collectively be evaluated using the
recommended PRGs for dioxin after adjustment to account for relative toxicity using
toxicity equivalency factors (TEFs) to calculate dioxin toxicity equivalent (TEQ)
concentrations.
