Abstract: The safety assessment on several organic pollutants in the Haihe River valley was introduced.There are three kinds of organic pollutants,i.e.pentachlorophenol,nonylphenol and nitrobenzene in the Haihe Rive that have environmental risk.Among the three pollutants,we must pay more attention to pentachlorophenol which environmental concentration in the Haihe River is 8.04 times higher than the no effect concentrations.The corresponding suggestions on the control of these pollutants were also given.
