This study provided the first assessment of pyrethroids and pyrethrins in Minnesota, USA lake sediments, second one for alkylphenols (APs) nonylphenol ethoxylates (NPEs). Surficial sediments were collected 2017 from 30 small to medium-sized lakes, encompassing a variety watershed land uses ecoregions. These lakes targeted pool 50 randomly selected included National Lakes Assessment (NLA) study....

Polyalcohol is an environmentally friendly anti-collapse lubricant commonly used in water-based drilling fluids. It generally composed of the single polyether or polyol, but its lubricity and inhibition can’t satisfy application current fluid systems well. Consequently, laboratory has carried out research on compound polyalcohol. The samples are mixed with lauryl polyether, nonylphenol Tween 80...

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...

This review summarizes peer-reviewed literature related to analysis, occurrence, and fate of emerging chemical contaminants in the water environment. The review focuses on the following broad categories of emerging contaminants: pharmaceuticals and personal care products (PPCPs); endocrine disrupting compounds (EDCs), including hormones, surfactants, and plasticizers; and brominated flame retar...

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...

A routine method is described for quantitative determination of 4-nonylphenol (NP), 4-nonylphenol monoethoxylate (NP1EO) and 4-nonylphenol diethoxylate (NP2EO) in sludge samples. A Soxtec extraction procedure was used to enrich target compounds from the solid matrix. Quantitative determinations were performed by high speed gas chromatography/mass spectrometry using a short apolar fused silica c...
