摘要

Nonylphenol (NP) is not a single chemical compound but a term used to refer to a family of compounds, all of which have a central aromatic (benzene) ring and a nine - carbon side chain. Surfactants related to NP are known as nonylphenol ethoxy-lates (NPEO). Alkylphenol ethoxylates (APEO) is the term used to describe the group of organic substances of which NPEO is one. These are mainly used as washing and cleaning agents (ie surfactants). These non-ionic surfactants are of particular interest currently as they are suspected to accumulate in the environment. They are thought to persist in rivers and their sediments, and are also concentrated by wildlife such as fish and birds, leading to contamination in their internal organs at much greater levels than in the surrounding environment.
