摘　　要：本实验石油污染土壤采自天津市大港石油田附近的土壤,研究了不同石油污染的土壤浸出液对大型蚤的危害性影响。研究表明,石油污染土壤的全盐量为3.1%,水解氮含量0.38g/kg,有效磷含量0.32 g/kg,有机质85.19mg/g,石油烃含量为10%,石油污染土壤对大型蚤危害性不强,在一定的水土比单位内是有危害性的,在一定的水土比范围内危害性比较强,水土比超过45就没有危害性了。This experiment studied the impact of oil contaminated soil to Daphnia magna which collected from oil field of Tianjin Dagang.The study showed that the content of total salt content,hydrolyzable nitrogen,available phosphorus,TOC TPHs are 3.1%,0.38g/kg,0.32g/kg,85.19mg/g,10%respectively and petroleum contaminated soil for Daphnia magna has less harmness.Contaminated soil shows some harmness within a certain range of water/soil ratio,more hazardous within a certain range of water/soil ratio,no impact when the ration is more than 45.
