PENTACHLOROPHENOL, POLYCHLORINATED DIBENZO-P-DIOXINS AND POLYCHLORINATED DIBENZO FURANS IN SURFACE SOIL SURROUNDING PENTACHLOROPHENOL-TREATED UTILITY POLES ON THE KENAI NATIONAL WILDLIFE REFUGE, ALASKA, USA

Composite surface soil samples were collected at 0, 25, and 50 cm from the base of 12 utility poles on the Kenai National Wildlife Refuge in Alaska, to assess the extent to which pentachlorophenol (PCP), polychlorinated dibenzo-p-dioxins, and polychlorinated dibenzo furans might have leached from PCP-treated poles. Each of six pairs of utility poles consisted of a pole manufactured in 1959 or 1963 and a pole manufactured within the past 20 years. A suitable background soil was sampled from each poles' vicinity. Old poles had greater concentrations of 2,3,7,8-TCDD equivalents (TEQs) near the pole base and at 25 cm than did newer poles. Surface soil levels of PCP and TCDD-TEQs exceeded both human health and ecological risk-based screening levels, suggesting that millions of similarly treated utility poles in North America might be point sources of PCP and dioxins/furans to soil. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6061508/
