In the present study a freshwater environmental risk was assessed for four surfactants used in household cleaning products in Japan. The statistically analyzed aquatic predicted no effect concentration (PNEC) of linear alkylbenzene sulfonate(LAS) polyoxyethylene alkylether(AE) and NN-dimethyl dodecyl aminoxide (AO) were assessed. The referred PNEC of dialkyl dimethyl ammonium chloride(DADMAC) was based on the practically conditioned bioassay applied river water. The predicted environmental concentrations (PEC) of these surfactants were estimated by analysis of the monitoring data and Pollutant Release and Transfer Register data. The estimates of the surfactants were calculated using removal rate at sewage treatment and dilution by environmental waters. The risk characterization as expressed by the PEC/PNEC ratio is below 1 for all surfactants. It is therefore considered that the use of these surfactants for household detergents may have only low ecological risk for the water environments in Japan.
