“…Today, a number of important food applications, 4,22,[29][30][31][32][33][34][35][36][37][38][39][40][41][42] as well as a small proportion of environmental applications, 4,43-46 using this column technology can be found in the literature, and several authors have compared the performance of core-shell column technology with that of sub-2 μm columns when dealing with this kind of applications. 4,31,35,45 The aim of this chapter is not to fully review the stateof-the-art in this topic, but in this section some relevant examples reported since 2011 will be addressed.…”

“…Regarding the potential risks, many countries have set up a maximum residue limit (MRL). For example, the U.S. Environmental Protection Agency (EPA) and the European Union (EU) have set a MRL value of 100 μg/kg for naphthylacetic acid (NAA) in pome fruits and a higher value (1000 μg/kg) for NAA in apples and pears . The EU has set up a MRL of 5 mg/kg for gibberellin A 3 (GA 3 ) in grapes , which signifies the requirements of the sensitive and accurate quantification methods for routine analyses of phytohormone residues in a number of food matrices.…”

“…An increasing number of novel techniques are being developed for determination of plant hormones. Many methods based on GC, LC, and CE coupled to MS, UV, or fluorescence detection (FLD) have been proposed for the analysis of multiphytohormones . In general, CE offers attractive features for little sample preparation and short analytical time, but the potential reproducibility might be the obvious problem.…”

Plant hormone determination in food matrices has attracted more and more attention because of their potential risks to human health. However, analytical methods for the analysis of multiple plant hormones remain poorly investigated. In the present study, a convenient, selective, and ultrasensitive high-performance liquid chromatography method for the simultaneous determination of multiple classes of plant hormones has been developed successfully using dispersive liquid-liquid microextraction followed by precolumn fluorescent labeling. Eight plant hormones in fruits including jasmonic acid, 12-oxo-phytodienoic acid, indole-3-acetic acid, 3-indolybutyric acid, 3-indolepropionic acid, gibberellin A3 , 1-naphthylacetic acid, and 2-naphthaleneacetic acid were analyzed by this method. The conditions employed for dispersive liquid-liquid microextraction were optimized systematically. The linearity for all plant hormones was found to be >0.9993 (R(2) values). This method offered low detection limits of 0.19-0.44 ng/mL (at a signal-to-noise ratio of 3), and method accuracies were in the range of 92.32-103.10%. The proposed method was applied to determine plant hormones in five kinds of food samples, and this method can achieve a short analysis time, low threshold levels of detection, and a high specificity for the analysis of targeted plant hormones present at trace level concentrations in complex matrices.

Color mothball is a daily necessity in Southeast Asia. Mothball contained nearly 100% naphthalene or 100% p-dichlorobenzene. It was used to resist insects, mothproof and mildew with a special odor. In other words, the odor was thought unpleasant enough to drive animals away in repellent products. This research analyzed color mothball which was manufactured by C and N companies. The mothball was dyed with eight dyes and three essences of fragrance, respectively. The experiment of color fastness with UV-light test is to determine how much the color will fade, when it exposed to a known ultraviolet light source. In the last analysis, the experimental data from the spectrum of GC/MS described all kinds of structure on color mothball after 80 hours phototherapy treatment as shown in the content. This research reveals that color mothball can have better appearance and greater performance, to meet the requirements for customs and various applications.
