The fate and removal of the estrogens 17beta-estradiol (E(2)), estrone (E(1)), and 17alpha-ethynylestradiol (EE(2)) and of the xenoestrogens bisphenol A (BPA), 4-tert-octylphenol (4-t-OP), 4-nonylphenol (4-NP), and nonylphenol mono- and diethoxylate (NPEO1 and NPEO2, respectively) were investigated in four South Australian sewage treatment plants (STPs; plants A-D) with different treatment tech...

This study aims at modelling the daily concentrations of nonylphenolic compounds such as 4-nonylphenol (4-NP), nonylphenol monoethoxylate (NP1EO) and nonylphenoxy acetic acid (NP1EC) within the Seine River downstream of Paris City for over a year, firstly in the present state (year 2010) and for years 2050 and 2100 in order to assess the consequences of global change on the fate of nonylphenoli...

Chemical cues are of enormous importance in mediating the behaviour of animals, enabling them to navigate throughout their habitats, to detect the presence of predators or prey and for social recognition-identifying and discriminating between conspecifics. In many species of freshwater fish, social recognition is known to be based primarily on chemical cues. Such recognition mechanisms are vuln...

Nonylphenol (NP), an estrogen like compound classified as an endocrine disrupter capably interfering hormonal system of numerous organisms, originates principally from the degradation of nonylphenol ethoxylates (NE) widely used in industrial, agricultural, commercial and household applications as detergents, emulsifiers, wetting and dispersing agents. Due to the extensive use of NE, NP may reac...

Nonylphenol (NP) and bisphenol A (BPA) are two typical endocrine disrupter chemicals (EDCs) in reclaimed water. In this study, the adsorptions of NP, a branched NP (NP7) BPA on water-irrigated soils were studied by isothermal experiments, different environmental factors their investigated. The results showed that NP7 conformed to Linear model, adsorption Freundlich model. decreased with increas...
