Dear Editor, I read with great interest the recent study by Yücedağ et al. [1] entitled " The Effects of Nonylphenol on Hearing in Rats. " It needs to be specified in the article if the hearing levels of the rats were evaluated before the study or not. Another point I would like to emphasize is that the hearing levels of the rats after the application of ethanol and nonylphenol were evaluated b...

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...

There is widespread use of chemical amendments to meet the demands for increased productivity in agriculture. Potentially toxic compounds, single or in mixtures, are added to the soil medium on a regular basis, while the ecotoxicological risk assessment procedures mainly follow a chemical by chemical approach. Picoxystrobin is a fungicide that has caused concern due to studies showing potential...

A new method for determining the endocrine disrupting substance 4-nonylphenol (technical grade=mixture of isomers, 4-NP) from water samples has been developed by using 4-(2,6-dimethylhept-3-yl)phenol (4-sec-NP) as model compound. This branched monoalkylphenol is shown to serve as internal standard (IS) for the determination of technical 4-nonylphenol. To the best of our knowledge, 4-(2,6-dimeth...

The effects of nonylphenol (NP) on phytoplankton and periphyton were studied in 230 L outdoor microcosms. Phytoplankton cell density and biomass, phytoplankton and periphyton diversity, and assemblage composition were analyzed during a four-week preapplication period, followed by six weeks of NP treatment via controlled release and a six weeks postapplication period. Changes in species richness...

n Analytical Conditions Nonylphenol (NP) is used as a raw material for the production of surfactants, and as an antioxidant used to protect rubber and plastics, etc. However, in recent years, it has been specified as a substance that can cause endocrine disruption in the environment (environmental hormone). NP, a type of alkylphenol, can theoretically exist as 211 structural isomers. Among thes...
