| Abstract | HEEP COPYRIGHT: BIOL ABS. A comprehensive quality assurance program was applied to the analysis of phthalate esters in sediment. By utilizing the rapid ultrasonic extraction of dried sediment and the detecton capabilities of selected ion monitoring mass spectrometry, the analytical scheme was simplified to reduce systematic errors due to contamination and to improve recoveries. Matrix blank levels were 2.5 ng in 5 g dry samples, and spiked field sample recoveries were 90%. Identification of different phthalate species was accomplished by multiple ion monitoring of characteristic ion fragments and retention time comparisons. Eleven phthalate species were measured in representative samples from various sites in the Chesapeake Bay and Chester River, Maryland (USA). |
