ABSTRACT
Chromatographic methods such as column high-performance liquid chromatography (HPLC), ultra-performance column LC (UPLC), and gas chromatography (GC) are currently the principal analytical techniques in food, environmental, and biological chemistry research. They can be used in the search for identification of the xenobiotics in food/environmental/biological samples and for quantitative analysis of analytes. Food safety assessment has received growing attention, and reliable analytical methods for the determination and quantification of xenobiotics play an important role in monitoring of agricultural procedures and processed products brought to the consumer. Hyphenated techniques enable data collection from numerous difficult samples, which proves very useful in correct separation, detection, identification, and quantitative analysis of xenobiotics. One of the most important scientific challenges will be an attempt to estimate the environmental exposure to xenobiotics and an attempt to estimate the relationship between xenobiotics and new elements of the environment—genetically modified food.
