Exogenous substances altering the function of the endocrine system and exhibiting adverse health effects on the organism are defined as endocrine disruptors. Nonylphenol is one of the most abundant alkylphenol ethoxylate derivatives, being detected in food products. Diverse studies have classified nonylphenol as hazardous to the health, especially to male reproduction. This in vitro study aimed...

Biochar adsorption presents a potential remediation method for the control of hydrophobic organic compounds (HOCs) pollution in the environment. It has been found that HOCs bound on biochar become less bioavailable, so speculations have been proposed that HOCs will persist for longer half-life periods in biochar-amended soil/sediment. To investigate how biochar application affects coupled adsor...

This paper aims to gather and discuss important information about nonylphenol, such as physical chemistry properties, toxicity and analytical methods in various matrices. As a degradation product of ethoxylated alkylphenols, nonylphenol presents a higher degree of reactivity than its precursor. Due to its harmful effects on the environment, use and production of nonylphenol has been banned in E...

Nonylphenol, an environmental estrogenic chemical, is reported to have adverse effects on the reproductive organs of animals. In this study, the metabolism of nonylphenol and that of other alkylphenols in the rat liver was investigated using liver perfusion. Alkylphenols (nonylphenol, hexylphenol, butylphenol, and ethylphenol) were glucuronidated by rat liver microsomes. Nonylphenol was found t...

Nonylphenol is an endocrine disruptor with harmful effects including feminization and carcinogenesis on various organisms. This study aims to investigate the distribution and ecological risks of nonylphenol in the Daliao River Estuary, China. Nonylphenol, together with other phenolic endocrine disruptors (bisphenol A, 4-t-butylphenol, 4-t-octylphenol, and 2,4-dichlorophenol), was detected in su...

Nonylphenol is the final biodegradation product of nonylphenol polyethoxylates, which are widely used surfactants in domestic and industrial products. Although nonylphenol is well known as an endocrine disrupting chemical, its effects on cell death and the mechanisms responsible for these apoptotic effects remain unclear. In the present study, Jurkat cells were treated with 0.1, 1 and 10 microM...

OBJECTIVE To explore the effects of nonylphenol on brain gene expression profiles in F1 generation rats by microarray technique. METHODS mRNA was extracted from the brain of 2-day old F1 generation male rats whose F0 female generation was either exposed to nonylphenol or free from nonylphenol exposure, and then it was reversely transcribed to cDNA labeled with cy5 and cy3 fluorescence. Subseq...

Alkylphenols are weak oestrogenic environmental contaminants and have been implicated in the disruption of endocrine function in wildlife. The influence of biotransformation, tissue distribution, and elimination on biological activity was investigated in juvenile rainbow trout following a single iv dose of [3H]4-nonylphenol. Distribution and elimination of [3H]4-nonylphenol residues in tissues ...

Introduction: In this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. Methods: Bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μM of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan bl...

The parr-smolt transformation in Atlantic salmon (Salmo salar) is a complex developmental process that culminates in the ability to migrate to and live in seawater. Exposure to environmental contaminants like nonylphenol can disrupt smolt development and may be a contributing factor in salmon population declines. We used GRASP 16K cDNA microarrays to investigate the effects of nonylphenol on ge...
