To survey the water pollution of Sagami River, 95 samples were collected by many citizens every 500 m right and left side alternately from Sagami Lake to Sagami Bay at Dec-1991 and Dec-1992. Chlorinated organic pollutants such as freon 113, Chloroform, 1,1,1-trichloroethane, tetrachloromethane, trichloroethylene and tetrachloroethylenein water were analyzed by GC-ECD using a head-space method. It was found that serious pollution (74700ppt) by trichloroethylene area existed 2km above the collection point for drinking water at Dec-1991. After this result reported by mass media preventive measures were carried out, and the trichloroethylene concentration at the point decreased remarkably at Dec-1992.}, pages = {1--8}, title = {相模川の有機塩素化合物による水質汚染調査 : トリクロロエチレンの高濃度汚染}, volume = {21}, year = {1995} }
