Nonylphenols and nonylphenol ethoxylates with one and two oxyethylene groups have been quantitatively determined in the effluents of six mechanical-biological sewage treatment plants. In three plants total concentrations of nonylphenolic compounds in the effluents ranged from 36 to 202 pg/L, representing from 0.5% to 2.3% of the total residual dissolved organic carbon. In three plants operated at low loading conditions nonylphenolic compounds were not detectable (
