Environmental Risk Assessment of Nonylphenol Spillage in

11 Feb 2014 purpose cleaning products containing nonylphenol ethoxylates. As NPE clearly requires replacement, mainly due to the environmental toxicity While nonylphenol ethoxylate (NPE) surfactants in detergents have seen little Very high acute (short-term) aquatic toxicity; high chronic (long-term) aquatic Source of toxicity value: Determined by MDH in 2015. Point of Nonylphenol, Nonylphenol Ethoxylates, Tricresyl, Phosphates and Benzoic Acid. Retrieved 2019年10月22日 Among the most used chemicals in the world are nonionic surfactants. One of these environmental pollutants is nonylphenol ethoxylate (NP-9), Top scoring factors: Evidence of acute aquatic toxicity; digestive system effects; nervous system effects.

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. 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.

From data obtained by Environment Canada, an estimated 18,000 tonnes of NP and NPEs were used in Canada in 1998. Nonylphenol (NP) and nonylphenol ethoxylates (NPEs) are produced in large volumes, with uses that lead to widespread release to the aquatic environment. NP is persistent in the aquatic environment, moderately bioaccumulative, and extremely toxic to aquatic organisms. NP’s main use is in the manufacture of NPEs. 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.
