Based on data on German food consumption rates and these first analyses of NPs in food, the daily intake for an adult was calculated to be 7.5 μg/day NPs. For infants exclusively fed with breast milk or infant formulas daily intakes of 0.2 μg/day and 1.4 μg/day NPs, respectively, ...
Nonylphenols (NPs) have shown greater toxicity than that of octylphenols (OPs) for all algae studied: the concentrations of NPs ( EC 50 ) that induce 50% inhibition of the growth of microalgae are 1.5–3.3 times lower than EC 50 for OP (depending on the culture). It has been ...
The aim of this work was to develop a simple and efficient analytical method for the determination of 4-nonylphenols (4-NPs) in marine sediments. Nonylphenols are a group of xenobiotics of great environmental concern owing to their endocrine-disrupting properties; they are recognised as priority ...
NPs accumulate in various organs and pose toxic effects on organisms. It has been listed as new pollutant under "China's 14th Five-Year Plan", with strict usage prohibition. Theoretically, technical nonylphenol consists of a mixture of 211 possible constitutional is...
It has recently become clear that an isomer-specific view is absolutely necessary when it comes to correctly evaluating the biological effects of NPs and their behavior in the environment, including degradation processes. To rationalize the identification of individual NP isomers in scientific studies, ...
Xenopus laevisOECD TG231Nonylphenols (NPs) are a group of endocrine-disrupting surfactants that mimic estrogen. To determine the developmental toxicity and thyroid-disrupting effect of NPs, the effects of exposure to nonylphenol (NP), 4-nonylphenol (4-NP), and nonylphenol ethoxylate (NP-12) were...
Nonylphenols (NPs) and nonylphenol carboxylates (NPECs) are products of the biodegradation of nonylphenol ethoxylates (NPEOs), which is a widely used group of nonionic surfactants. These compounds are persistent, toxic, and exhibit estrogenic activity. Global scientific and public discourse has ...
Nonylphenols (NPs) and bisphenol A (BPA) are the most common endocrine disruptors detected in the coastal waters of Hong Kong. The Cape D'Aguilar Marine Reserve (CAMR), the only marine reserve in Hong Kong is close to urbanized areas, thus the resident marine organisms are inevitably ...
The study demonstrated also that the polychromatic UV-light alone and also in combination with selected oxidizers (i.e. hydrogen peroxide, ozone) may be successfully used for the removal of selected NPs from the aqueous medium.doi:10.2166/wst.2015.011Felis, E.Miksch, K....
The decomposition curves of NPs at each initial concentration were analyzed as single exponential functions. Alkylphenol activity of aqueous NPs solution, which was estimated by enzyme-linked immunosorbent assay, implies the irradiation products have alkylphenol activity. Two products having molecular weight...
