Behaviour of the endocrine disrupting chemical nonylphenol in soil: Assessing the risk associated with spreading contaminated waste to land

Distribution and accumulation of endocrine-disrupting chemicals and pharmaceuticals in wastewater irrigated soils in Hebei, China

“…RQ values for soil terrestrial organisms were calculated from the measured environmental concentration (MEC) and the predicted no effect concentration (PNEC) of each compound (European Commission, 2003). It has been reported that 4-nonylphenol in soil did not adversely affect soil respiration or plant growth until its concentration reached 10,000 mg/kg, and the uptake by plants was very low (Roberts et al, 2006). The RQ values for 4-nonylphenol was all less than 1 based on the measured soil concentrations in the present study and the PNEC value of 0.3 mg/ kg (European Commission, 2002).…”

Potential for phytoremediation of nonylphenol from sewage sludge

“…The first‐order model, square root first‐order model, biphasic model, bi‐exponential model, and exponential model were used to fit the dissipation data (Hseu, 2006; Langdon, Warne, Smernik, Shareef, & Kookana, 2011, 2012; Zhang, Spiteller, Guenther, Boehmler, & Sebastian, 2009). Most studies (Roberts et al., 2006; Sjöström, Collins, Smith, & Shaw, 2008) have used the first‐order model to fit dissipation data; therefore, this study used the first‐order model using GraphPad prism 7.0 to fit the dissipation data.…”

Mg–Al–CO3 hydrotalcite removal of persistent organic disruptor — Nonylphenol from aqueous solutions

“…Nonylphenol (NP) is a toxic organic substance classified as an endocrine disruptor adversely affecting the endocrine system during prolonged exposure (Roberts et al, 2006). It arises as a metabolite of degradation of nonylphenol ethoxylates (NPEO), which are widely used in industry as non-ionic surfactants.…”
