[Degradation of nonylphenol and short chain nonylphenol polyethoxylates in soil].
Biodegradation of nonylphenolic estrogens in soil and sludge-amended soil were investigated. Biodegradations of nonylphenol (NP), nonylphenol monoethoxylate (NPEO1) and nonylphenol diethoxylates (NPEO2) followed the first-order kinetics, and the degradation rates were enhanced when the temperature was increased. Spiked NP, NPEO1 and NPEO2 (with the concentration of 100, 50 and 100 mg x kg(-1), respectively) could be degraded completely in 45 days at the temperature of 30 degrees C. NP presented a higher degradation rates in soil than NPEO1 and NPEO2 under the same condition. The amended sludge enhanced the biodegradation of NPEO1 and NPEO2 in soil, while it inhibited that of NP.
