Nonylphenol is an endocrine-disrupting chemical that mimics estrogenic activity. Few studies have investigated the soil ecotoxicity of nonylphenol in the environment, based on probabilistic approaches. The present study generated soil toxicity data for nonylphenol through bioassays that determined the acute and chronic species sensitivity distributions and estimated the hazardous concentrations of nonylphenol in soil in order to protect soil ecosystems. We used eight soil-based organisms from six taxonomic groups for acute assays and five soil-based organisms from four taxonomic groups for chronic assays. The hazardous concentration values of nonylphenol in soil, based on acute and chronic species sensitivity distributions, were estimated using compiled data from the present study, as well as previous studies. This is the first study that generated sufficient data to develop species sensitivity distributions for nonylphenol in soil, and to determine hazardous concentrations of nonylphenol for soil environments.
