摘　　要：从样品采集与保存、样品前处理、多环芳烃的检测3个方面介绍了测定海水和海洋沉积物中多环芳烃的步骤和最新进展。对目前较为常用的几种样品前处理方法,如液-液萃取、固相萃取、固相微萃取、索氏提取、超声提取、微波萃取、超临界流体萃取、加速溶剂萃取;以及检测方法,如气相色谱-质谱法、高效液相色谱法等作了详细介绍,比较了各自的优缺点。对目前较为常用的2种多环芳烃的来源解析方法(分子指纹法和同位素指纹法)的相关研究进展进行了总结。This review focuses on the sample collection and storage, sample pretreatment, analysis of polycyclic aromatic hydrocarbons（PAHs） for the determination of PAHs in seawater and marine sediment samples. Several extraction techniques, such as liquid-liquid extraction, solid phase extraction, solid phase microextrac- tion, soxhlet extraction, ultrasonic extraction, microwave assisted extraction, supercritical fluid extraction and accelerated solvent extraction, and analysis methods such as gas chromatography-mass spectrometry and high performance liquid chromatography, are described and compared. The progress on two major methods for source identification of PAHs, i.e., molecular fingerprinting and isotope fingerprinting, is summarized.
