Nonylphenol ethoxylates, NPE Rapid Test Kit is a lateral flow rapid test to detect NPE in milk and milk powder samples. Water samples may also apply.
Nonylphenol ethoxylates are nonionic surfactants that are used in a wide variety of industrial applications and consumer products. Many of these, such as laundry detergents, are “down-the-drain” applications. Some others, such as dust-control agents and deicers, lead to direct release to the environment. NPEs, though less toxic and persistent than NP, are also highly toxic to aquatic organisms, and, in the environment, degrade into NP.
NP and 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 has also been shown to exhibit estrogenic properties in in-vitro and in-vivo assays. NP’s main use is in the manufacture of NPEs. NP and NPEs have been found in environmental samples taken from freshwater, saltwater, groundwater, sediment, soil and aquatic biota. NP has also been detected in human breast milk, blood, and urine and is associated with reproductive and developmental effects in rodents.
This NPE rapid test kit is based on an indirect competitive immunoassay of the specific reaction of NPE and NPE monoclonal antibodies. NPE-7, NPE-9, NPE-10 can be detected with this kit in less than 10min.
