To　detect　the　PAEs　in　environment　accurately,　a　method　for　the　determination　of　six　phthalic　acid　esters　of　environmental　hormone　in　sediment　samples　by　using　microwave-assisted　extraction　and　gas　chromatography　was　proposed.　Several　factors　that　affect　recoveries　of　analytes　were　optimized　by　orthogonal　design.　The　optimized　results　were　as　follows:　extractant　was　Acetone:hexane　(1:1),　extraction　time　was　15　min,　extraction　pressure　was　0.2　MPa,　and　extraction　power　was　70%.　Linear　correlation　coefficient　was　over　0.99.　The　range　of　linear　was　1-500　mg/L.　The　limits　of　detection　was　between　0.40　and　4.58　mg/L.　The　repeatability　expressed　as　relative　standard　deviation　was　between　5.9%　and　12.3%.　The　method　was　applied　to　analyze　six　phthalic　acid　esters　of　environmental　hormone　in　sediment　of　park　water　environment.　Six　phthalic　acid　esters　were　determined　by　different　degrees.　The　volumes　of　BBP　were　250.6　μg　per　gram　of　soil　and　281.2　μg　per　gram　of　soil,　while　the　volumes　of　DEHP　were　259.9　μg　per　gram　of　soil　and　170.3　μg　per　gram　of　soil.
