Polycyclic aromatic hydrocarbons (PAHs) are a large category of ubiquitous persistent environmental pollutants, some of them have strong carcinogenicity to human and animals. These pollutants can easily enter the river through multiple ways including rainfall, dry deposition and water washout, and deposit in the sediment. However, it is easy for them to re-enter the river water and pollute water sources, as well as aquatic animals and plants, bringing potential harm to human health. Therefore, it is requisite to accurately analyze the PAHs in sediment. In this review, the analytical methods of PAHs in sediment, focused on the methods of sample extraction, purification, concentration and determination, are summarized.

沉积物中多环芳烃的样品制备和分析方法

多环芳烃(PAHs)是一类普遍存在的持久性环境污染物,其中一些对人类和动物具有强烈的致癌性。这些污染物可以通过多种方式轻松进入河流,包括降雨,干沉降和水冲刷以及沉积在沉积物中。但是,它们很容易重新进入河水和污染水源以及水生动植物,对人体健康造成潜在危害。因此,有必要对沉积物中的多环芳烃进行准确分析。本文综述了沉积物中多环芳烃的分析方法,重点是样品的提取,纯化,浓缩和测定方法。
