ABSTRACT

4-nonylphenol (4-NP) is metabolite of nonylphenol polyethoxylates which are anthropogenicaly-produced substances utilized in many consumer products. Because of its close association with household products, large quantity of 4-NP, which is highly hydrophobic, can be quickly sorbed by the organic rich solid phase during wastewater treatment. Concentrations as high as several thousand mg/kg (ppm) have been detected for 4-NP in biosolids, making biosolids a possible major source for 4-NP in the environment. Land application of biosolids as soil amendment has been a cost-effective biosolids management option for many municipalities. Biosolids production in the United States reached 8.2 million dry ton/year in 2010, 70% of which was land applied. However, there is a strong concern over potential pollution of the environment with various biosolids-associated anthropogenic chemicals such as 4-NP. 4-NP can bind to estrogen receptors, making it a threat to various organisms in the environment. There is a need for fast, accurate, and sensitive detection of 4-NP in environmental samples.
