Environmental Risk Assessment of Nonylphenol Spillage in

The addition of ethoxyl groups to the parent compound produces nonylphenol ethoxylates (NPE), which are used to produce industrial surfactants. As per the Government of Canada (2007), “Nonylphenol ethoxylates (NPEs) are a class of the broader group of compounds known as alkylphenol ethoxylates (APEs). NPEs are high-volume chemicals that have been used for more than 40 years as detergents, emulsifiers, wetting agents and dispersing agents. Nonylphenol polyethoxylate-containing products are used in many sectors, including textile […] Alkylphenol ethoxylates and alkylphenols - update information on occurrence, fate and toxicity in aquatic environment. ence of nonylphenol ethoxylate surfactants and their pri- 2018-06-20 · The U.S. Environmental Protection Agency (EPA) expanded on June 12, 2018, the list of chemicals subject to reporting under the Emergency Planning and Community Right-to-Know Act (EPCRA) Toxics Release Inventory (TRI). The list now includes a category containing 13 nonylphenol ethoxylates (NPE).

Shorter ethoxylate chain alkylphenols have greater toxicity than longer ones. CCME describes Toxic Equivalent Factors from Environment Canada for NPnEO (1≤n≤8) Nonylphenol is toxic to aquatic organisms demonstrated, in part, through recent national criteria established by the EPA (AWQC– Nonylphenol 2007( EPA822R05005)).

Leaching of Hazardous Substances from Concrete

of nonylphenol ethoxylates produces more toxic nonylphenol (NP) (Hano et al., 2009). Such compound is also estrogenic both in vitro and vivo assays (Folmar et al., 2002).

53:599-606. Toxicity of Nonylphenol Ethoxylate Metabolites Many countries, large corporations and scientific entities have classified NPE metabolites as toxic.

The addition of ethoxyl groups to the parent compound produces nonylphenol ethoxylates (NPE), which are used to produce industrial surfactants. Nonylphenol and short-chain nonylphenol ethoxylates such as NP 2 EO are present in aquatic environment as wastewater contaminants, and their toxic effects on aquatic species have been reported.

nonylfenol — Engelska översättning - TechDico

It originates principally from the degradation of nonylphenol ethoxylates which are widely used as industrial surfactants. 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. Nonylphenol (NP) (CAS number, 104-40-05) is a product of industrial synthesis formed during the alkylation process of phenols (ring structure in Figure 1). The addition of ethoxyl groups to the parent compound produces nonylphenol ethoxylates (NPE), which are used to produce industrial surfactants.

2020-04-11 · Electronic address: joliverov@unicartagena.edu.co. 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. 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. According to the classification provided by companies to ECHA in CLP notifications this substance is toxic to aquatic life with long lasting effects, causes serious eye damage, is harmful if swallowed and causes skin irritation.
