Comprehensive two-dimensional gas chromatography (GC×GC) offers increased peak capacity and selectivity relative to conventional one dimensional separations. The analysis of persistent organic pollutants in environmental matrices is very challenging due to the large number of compounds with varying chemical and physical properties that are typically present in the sample at the same time at concentrations ranging from ultra-trace to percent levels. GC×GC is steadily gaining in popularity in environmental analysis and the number of publications citing the use of this technique has been increasing significantly in the recent years. An overview of the latest applications in the environmental field is presented in this paper, emphasizing the advances for targeted and non-targeted analysis in complex matrices. In addition, instrumentation, data interpretation approaches, as well as the quality assurance and control for routine analyzes are discussed.

全面的二维气相色谱（GC×GC）相对于传统的一维分离提供了更高的峰容量和选择性。由于大量同时具有不同化学和物理特性的化合物通常同时存在于样品中，浓度范围从超痕量到百分含量，因此分析环境基质中的持久性有机污染物非常具有挑战性。GC×GC在环境分析中稳步普及，近年来引用这种技术的出版物数量显着增加。本文概述了环境领域的最新应用，重点介绍了复杂基质中目标分析和非目标分析的进展。另外，仪表
