Green chemical analysis: main principles and current efforts towards greener analytical methodologies

Green chemistry, green analytical chemistry and green sample preparation are related areas that have been developing since the 90s, aiming to moderate the adverse impacts of chemical practices on the environment and human health. Presently, a set of green principles has been established, which is a collection of rules that need to be followed to perform chemical practices with a lower negative impact on the environment. Herein, we comprehensively review green chemical analysis by combining historical aspects and ongoing efforts of green analytical methodologies. Through four systematically designed chapters, information is presented on the aspects of green analytical chemistry, including its fundamentals, metrics, modern strategies and future trends.

Current Sample Preparation Methods and Determination Techniques for the Determination of Phthalic Acid Ester Plasticizers in Edible Oils

In the process of production, processing, transportation, and storage of edible oils, the oils inevitably come into contact with plastic products. As a result, plasticizers migrate into edible oils, are harmful to human health, and can exhibit reproductive toxicity. Therefore, the determination of plasticizers in edible oils is very important, and a series of sample preparation methods and determination techniques have been developed for the determination of plasticizers in edible oils. Phthalic acid ester (PAE) plasticizers are the most widely used among all plasticizers. This review aims to provide a comprehensive overview of the sample preparation methods and detection techniques reported for the determination of PAEs in edible oils since 2010, focusing on sample preparation methods of edible oils combined with various separation-based analytical techniques, such as gas chromatography (GC) and liquid chromatography (LC) with different detectors. Furthermore, the advantages, disadvantages, and limitations of these techniques as well as the prospective future developments are also discussed.
