Phenolic endocrine-disrupting compounds in the Pearl River Estuary: Occurrence, bioaccumulation and risk assessment

4-Nonylphenol effects on rat testis and sertoli cells determined by spectrochemical techniques coupled with chemometric analysis

“…NP belongs to category 1 (clear evidence of endocrine disrupting effects in an intact organism) of the endocrine disrupter priority list (Wang et al, 2016). The occurrence of NP has been reported in different environmental compartments worldwide, as well as within humans and other biota (Fairbairn et al, 2016;Staniszewska et al, 2016;Wang et al, 2016;Diao et al, 2017;Lin et al, 2017;Peng et al, 2017). According to a study conducted in the Zumbro River watershed of United States, the concentration of NP was up to 10 4 ng/L (Fairbairn et al, 2016).…”

“…According to a study conducted in the Zumbro River watershed of United States, the concentration of NP was up to 10 4 ng/L (Fairbairn et al, 2016). In the Pearl River Estuary of China, NP was identified at concentrations ranging from 233.04 to 3352.86 ng/L in surface water and 7.55 to 20.80 ng/g of dry weight (dw) in sediment (Diao et al, 2017). As regards exposure to wildlife and humans, high NP levels (111.2 ng/g dw) were determined in zooplankton off the Gulf of Gdansk (Southern Baltic) in the years 2011-2012 and, additionally, NP was found in cord blood plasma with a median concentration of 72.6 ng/mL in 208 children from Taiwan (Staniszewska et al, 2016;Lin et al, 2017).…”

“…Recent studies show the presence of 4-nonylphenol, 4-tert-octiphenol, and bisphenol A in sediments and waters. Although the risk factors for organisms are still considered low, the potential danger posed by these components should be considered [1], In addition, other studies [2,3] report concentrations of these components in different substrates, finding a direct relationship between the months with low rainfall and the concentration of these pollutants [4].…”

Adsorption of Nonylphenol to Multi-Walled Carbon Nanotubes: Kinetics and Isotherm Study

“…In general, the treated wastewater discharged from industrial parks in the Asian region including China, Indonesia, Korea, Laos, Malaysia, Taiwan, Thailand, and Vietnam contains a higher concentration of NP than that in the European Union, America, and Japan [6][7][8]. Table S1 summarizes the levels of NP detected in several major Asian rivers [6,7,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Generally, these rivers flow by industrial parks and WWTPs, which are the potential sources of NP.…”
