The Decomposition of Pentachlorophenol When Applied as a Residual Pre‐emergence Herbicide¹

Baseline Risk Assessment for the F-Area Burning/Rubble Pits and Rubble Pit

“…Pentachlorophenol is rapidly metabolized by soil microbes, and this is the major degradation pathway in soils (Kauhan 1978). The degradation rate increases with increasing organic content =/or increasing moisture content (Young and Carroll 1951).…”

Contamination of the Freshwater Ecosystem by Pesticides

“…An increase in organic matter reduced downward movement. Young & Carroll (1951) reported that pentachlorophenol decomposes more rapidly in soils of high than in soils of low organic matter content, and rate of decomposition is more rapid when moisture content is near the moisture equivalent. Jones & Moyle (1963) collected 2-in.…”
