Summary The persistence and biotoxicity of nonylphenol, a mixture of monoalkyl phenols that is found in relatively high concentrations in sewage sludge, were studied in an incubation experiment with a reconstituted soil system (compost + sandstone). The effect of nonylphenol (100 and 1000 ppm) on CO2 evolution and biomass ATP were monitored. Nonylphenol depressed CO2 production significantly only at high concentrations [1000 ppm 4-nonylphenol (4-NP)]. Biomass ATP declined progressively after the 5th day. At 100 ppm no toxic effects were detected. After a lag phase, nonylphenol disappeared readily upon incubation at the lower concentration (100 ppm), but persisted at high levels (1000 ppm). The persistence of 4-nonylphenol increased under aseptic conditions. The chromatogram profile of 4-NP changed over time, indicating that some of the isomers are more easily degraded than others.
