Abstract
Tests were conducted to determine the effects of pentachlorophenol (PCP) in feed on growth and bioaccumulation in mallard ducklings. Significant effects of PCP on growth (LOAEL) were observed after 11 days at 961 micrograms/g PCP. The NOAEL value (no significant growth effects) was 423 micrograms/g PCP. Concentrations of PCP in tissues at the NOAEL were 20.7 (liver), 12.2 (lipid), 3.3 (muscles), and 2.6 (brain) micrograms/g (wet wt.); no bioaccumulation was observed. Using a toxicity threshold model, it was estimated that about 1.1 mg/L of waterborne PCP was a threshold for adverse effects for mallard ducks.
