The results showed that the calibration curves were linear in the ranges of 1.0~100 μg / L for target compounds, with correlation coefficients larger than 0.999. The limits of detection were 0.08~0.17 μg/L. The certified reference material of sediment (SRM1944) was chosen as the subject investigated. QuEChERS method was compared with traditional methods, and verified with sediments samples. The recovery ranges were 87.8%~100.3%. This method was demonstrated to be quick, easy, rugged and safe. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
