Occurrence and Fate of Nonylphenol Ethoxylates and Their Derivatives in Nansi Lake Environments, China
The vertical and horizontal distribution of nonylphenol polyethoxylates (NPEO n , n = number of ethoxy units) and their derivatives in the Upper Nansi Lake, North China, were investigated using high-performance liquid chromatography (HPLC) and liquid chromatography-tandem mass spectrometry (LC-MS/MS...

| Zusammenfassung: | The vertical and horizontal distribution of nonylphenol polyethoxylates (NPEO n , n = number of ethoxy units) and their derivatives in the Upper Nansi Lake, North China, were investigated using high-performance liquid chromatography (HPLC) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods. For the water-phase concentrations of these compounds, data are omitted because of their low concentration levels. The content of NPEO n (n = 1 to 15) bound onto the sediment of this lake changed in the range of 60.7 to 631.5 µg/kg dry for sediment cores with a thickness up to 350 mm. A typical increasing trend of the nonylphenol (NP) content was revealed along the water flow direction of this lake. Carbonated NPEO n (NPE n C) showed an increasing trend from upstream to downstream, with the total concentrations of the NPEO n falling in the range of 2.13 to 23.1 µg/kg dry. Results indicate that this lake received some effluent from wastewater treatment plants, whose treatment ratios are relatively low in this area. The nonoxidative hydrolytic transformation is a significant process occurring within the sediment phase of Nansi Lake. |
