Endosulfan is widely used around the world broad-spectrum pesticides,it began to producte and use from the 20th century the 50’s.Recent studies show that endosulfan has persistence and estrogen effect,and has carcinogenic and teratogenic effect,both in vivo and the icing of the polar are found endosulfan residues.It currently got a wide range of scholars’ attention,but no system reports yet been seen in our country.Dalian region locate at the south of the byland of Liaodong between Bohai and Huanghai with the agriculture of fruit and vegetable.Endosulfan may be used in the region.We built a monitoring net about air samples and soil samples for one year.The atmosphere in Dalian cantonal concludesα-endosufan,β-endosulfan and endosulfan sulfate.PUF endosulfan show a high concentration in June,Aug.GFF endosulfan show a high concentration in Jan.The PUF endosulfan in June and Aug.are 47 times and 152 times respectively as the GFF endosulfan at the same time.The GFF endosulfan in Jan.is 20 times as the PUF endosulfan at the same time.The temperature is significance correlation with endosulfan rather than air-press and wind speed (significance level 5%).The monitoring results in Dalian Region show that the concentration of endosulfan is relatively high in atmosphere of Jinzhou,Pulandian and Zhuanghe throughout the whole year.The analysis of endosulfan composition in atmosphere shows that there is emission of endosulfan in spring and summer of Pulandian,and in summer there is emission of endosulfan in Wafangdian,Zhuanghe and Lushun.There is emission of endosulfan in autumn in Changhai.There is not emission of endosulfan in winter in Dalian Region.The endosulfan in summer in Dalian Region mainly comes from eastern and south-east,and it is mainly PUF endosulfan.
