Abstract. Sludge agriculture application in future will be one of the main sewage sludge disposal ways in China. To ensure safety and environment of sewage sludge agriculture application, except to strengthen the research of sludge heavy metal, pathogen outside the organic contaminants will be one of the focuses of the future research, especially to strengthen the PAHs and NP/NPE. In order to reduce the environmental risks of sludge agriculture application, using biological aerobic fermentation processing technology treatment sludge can effectively reduce the organic contaminants, depress secondary pollution problem, which sewage sludge brings.

Average concentrations of NP and NPEOs of these four major STPs were used to calculate their PCCs by equation (1) according to an investigation of the influent volume and population served of the STPs in the Wenyu River catchment (shown in the Table S2 in supporting information).…”

“…Many studies of the fate and degradation of NP and NPEOs in STPs in China are available, but a study conducted by Lian et al (2009) in four types of STPs in Beijing provides the most relevant references for our study. In Lian et al (2009) study, the removal rates of NP and NPEOs in STPs were investigated in four STPs that used different types of treatment processes, with a biomembrane and an oxidation ditch. The average influent and effluent concentration of NP in activated sludge (AS) is 0.034 and 0.001 μmol/L, respectively.…”

The environmental risk presented by Bdown-thedrain^chemicals to receiving rivers in large urban areas has received increasing attention in recent years. Geo-referenced Regional Environmental Assessment Tool for European Rivers (GREAT-ER) is a typical river catchment model that has been specifically developed for the risk assessment of these chemicals and applied in many European rivers. By utilizing the new version of the model, GREAT-ER 3.0, which is the first completely open source software for worldwide application, this study represents the first attempt to conduct an application of GREAT-ER in the Wenyu River of China. Aquatic exposure simulation and an environmental risk assessment of nonylphenol (NP) and its environmental precursor nonylphenol ethoxylates (NPEOs) were conducted effectively by GREAT-ER model, since NP is one of typical endocrine disrupting chemicals (EDCs) and its environmental precursor NPEOs as a Bdown-the-drain^chemical are extensively used in China. In the result, the predicted environmental concentrations (PECs) of NP and NPEOs in the water of Wenyu River were 538 and 4320 ng/L, respectively, at the regional scale, and 1210 and 8990 ng/L, respectively, at the local scale. From the results profile of the RCR, the combination of high emissions from large STPs with insufficient dilution of the river caused the high RCR. The PECs of NP in the sediment were in the range of 216.8-8218.3 ng/g (dry weight), which was consistent with the available monitoring data. The study showed the worldwide applicability and reliability of GREAT-ER as a river catchment model for the risk assessment of these chemicals and also revealed the general environmental risks presented by NP and NPEOs in the Wenyu River catchment in Beijing due to the extensive use of these chemicals. The results suggest that specific control or treatment measures are probably warranted for these chemicals to reduce their discharge in major cities.

“…They are typically applied in industrial, household and commercial applications used in cleaning, wetting, dispersing, emulsifying, foaming, and anti-foaming agents. [1][2][3] Nonylphenol polyethoxylates (NPnEOs; n indicates the number of ethoxy units), one of the major classes of nonionic surfactants, are used worldwide. A typical chemical structure of NPnEOs is comprised of nonylphenol (NP) group and variable ethoxy (EO) chains with an average chain number about 10.…”

“…6 Recently, separation instrument combined with mass spectrometer such as gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS) has been shown to be efficient to determine trace NPnEOs and its degradation products. [1][2][3][4][6][7][8][9][10][11][12] The high sensitivity and selectivity of MS can improve the problems of compounds co-eluting and lack of individual standards of NPnEOs. The APCI technique of LC/MS was adopted in this study due to the lower matrix interference and more stable analyte response in the NPnEOs analysis.…”

In this study, liquid chromatography/mass spectrometry was used to analyze the trace amounts of nonylphenol polyethoxylates (NPnEOs) in industrial water effluents. The modifier of acetic acid added in mobile phase and the atmospheric pressure chemical ionization (APCI) coupled with linear ion trap mass spectrometry were adopted to improve the sensitivity of NPnEOs analysis. The modification extraction technique of NIEA W801.50B method announced by Taiwan Environmental Protection Agency was used as sample preparation. The analytical results show that the LODs of NPnEO analytes were 0.02-10 ng/mL. The proposed method has been successfully applied to monitor trace NPnEOs in real industrial water effluents.
