9 May 2015 Nonylphenol ethoxylates (NPEs) are surfactants that have been in commerce NP and NPEs were determined to be Toxic under CEPA 1999

NPEs (nonylphenol ethoxylates) break down in the environment into nonylphenol (NP), one of the most notorious examples of persistent, bioaccumulative and toxic chemicals (PBTs). Widely recognized for extreme aquatic toxicity to fish and wildlife, NPEs and NP may also threaten the health of the developing fetus and young children.

(1992) Determination of alkylphenol ethoxylates and their acetic acid (1984) 4-nonylphenol in sewage sludge: Accumulation of toxic metabolites from nonionic av A Julander · Citerat av 2 — Other substances that are highly toxic at skin exposure are substances and preparations (nonylphenol, nonylphenol ethoxylate and cement) (Text with. Engelska. The EESC carried out searches of databases with regard to the toxicity of nonylphenol, nonylphenol ethoxylate and cement and their various uses in expert panel report on the reproductive and developmental toxicity of bisphenol A. The effects of 4-nonylphenol in rats: a multigeneration reproduction study. DODECYLBENZENE SULFONATE AND NONYLPHENOL ETHOXYLATE.

The term “nonylphenol” represents a large num-ber of isomeric compounds, varying in the point of attachment of the nonyl group to the phenol molecule, and in the degree of branching in the nonyl moiety. Commercially produced nonylphenols are predominantly In sewage treatment plants, nonylphenol ethoxylate degrades into nonylphenol, which is found in river water and sediments as well as soil and groundwater.

Nonylphenol and its ethoxylates. • EC (2001), EU-RAR on 4-nonylphenol (branched) and Nonylphenol. Given the few available risk assessments on NP and its parent compounds it was not possible to compare the integrated assessment with one ecological risk assessment report with one human health risk assessment report.

NP’s main use is in the manufacture of NPEs. Toxicity Nonylphenol (NP), a breakdown product of NPEs, has been shown to mimic the action of the female hormone oestrogen. Concerns have focussed on the potential for NP and NPE to cause feminisation in wildlife, such as fish exposed to NP and NPE contaminated effluents, as well as being a potential factor in the increasing incidence Toxicity of nonylphenol, nonylphenol monoethoxylate, and nonylphenol diethoxylate and mixtures of these compounds to Pimephales promelas (fathead minnow) and Ceriodaphnia dubia. Archives of Environmental Contamination and Toxicology .

Nonyl-phenol ethoxylates have much narrower homologue distributions than alcohol ethoxylates (ICI datasheet for Synperonic NP surfactants). 880 million pounds (4 mio metric tonnes) of alkyl phenol ethoxylates are used annually throughout the world. 80-85% are sold as nonylphenol ethoxylate (NPE), over 15% as octylphenol ethoxylate, and 1% each as

Nonoxynol-9, the compound with 9 repeating ethoxy groups, is a spermatocide, formulated primarily as a component of vaginal foams and creams. Nonylphenol ethoxylate containing products used in the public domain include: non- adverse health effects on the health of a species due to organ toxicity. 3. 3 Jun 2014 The aim of this paper was to examine the sublethal toxic effects of nonylphenol ethoxylate (NP10EO), its primary degradation product As a degradation product of ethoxylated alkylphenols, nonylphenol presents a higher degree of reactivity than its precursor. Due to its harmful effects on the EPA is proposing to add a NPEs category to the list of toxic chemicals subject to 27 Nov 2016 Nonylphenol Ethoxylates (NPE) are used in a wide variety of industrial applications and consumer products. NPEs, though less toxic than NP, 20 Jun 2018 The agency proposed to add short-chain NPEs to the EPCRA toxic chemical list because they are believed to be highly toxic to aquatic organisms 8 Jun 2018 EPA states that its assessment of long-chain NPEs “is that, depending on chain length, they are low to moderately toxic to aquatic organisms but The freshwater standards are based on toxicity of NP to fathead minnow, the incomplete biodegradation of nonylphenol ethoxylate (NPE) surfactants during 8 Jun 2018 Short-chain NPEs, which consist of a nonylphenol with one or two ethoxylene oxide groups attached, are highly toxic to water-dwelling organisms Get the Facts: NPEs (nonylphenol ethoxylates) · Hormone (endocrine) disruption · Extreme aquatic toxicity · Skin and eye irritation · Reproductive harm · Birth defects 2004. Toxicity of Nonylphenol Ethoxylate.

toxicity tests were collected from the littoral area of Sancti Petri (Gulf of Cadiz, southwest of Iberian Peninsula). Main physico-chemical and biological characteristics of the sea water used are summarized in Table I. Assessment of the Biodegradability and Ecotoxicty of a Nonylphenol Ethoxylate Surfactant in Littoral Waters Among the most used chemicals in the world are nonionic surfactants. One of these environmental pollutants is nonylphenol ethoxylate (NP-9), also known as Tergitol, and its degradation product, nonylphenol (NP).

Among the most used chemicals in the world are nonionic surfactants. One of these environmental pollutants is nonylphenol ethoxylate (NP-9), also known as Tergitol, and its degradation product, nonylphenol (NP). The objective of this work was to determine the toxicity of NP and NP-9 in Caenorhabditis elegans.

The ethoxylated isomers of nonylphenol (NPEs, NP-9) are one of the main active ingredients present in nonionic surfactants employed as herbicides, cosmetics, paints, plastics, disinfectants and detergents. These chemicals and their metabolites are commonly found in environmental matrices.
