Surfactants are usually divided into four major categories:anions,cations,nonionic and amphoteric ions.They are widely used in all walks of life.In agriculture,they are used mainly with pesticides and fertilizers,and can also be used for the remediation of contaminated soil.But with its mass use,it also brings harm.A large number of experiments have proved that nonylphenol has endocrine toxicity,neurotoxicity,reproductive toxicity,immunotoxicity,ecological toxicity and genetic toxicity.Its LC50 to 96 h of Rana chensinensis is 170 μg/L,and the 50 day lethal concentration of mussel is 140 μg/L.In the future,the research on the toxicity of surfactants to human body should be strengthened.Meanwhile,the way of efficient degradation and removal of toxic surfactants,as well as better green surfactants should be found out.
