An accurate, rapid and reliable method for the simultaneous determination of pesticide multi-residues in 9724 samples imported fresh fruits and vegetables by a method of liquid chromatography coupled with tandem mass spectrometry LC–ESI (+)-MS/MS operating in multiple reaction monitoring (MRM) mode, two transitions for each compound in the presence of internal standards and modified quick, easy, cheap, effective, rugged, safe (QuEChERS) method was used for the determination of 343 pesticides. The performance of the analytical method was validated in accordance with EU SANCO guidelines (SANTE/12682/2019) for monitoring pesticide multi-residues. Residues of 93 compounds, mainly fungicides and insecticides, were detected in 3548 samples. In this article, The potential applications of Liquid Chromatography and Tandem Mass spectrometry (MS/MS) techniques on monitoring pesticide residues of target samples of imported fruits and vegetables in United Arab Emirates (UAE) during the year 2019 is reported. The need for a continuous monitoring program of pesticide residues in imported fruits and vegetables is highly recommended and continuous process control for health and safety practices and to adhere to international agricultural and environmental policies of the country.
The occurrence of pesticide residues in representative samples collected from imported dates palm fruits during 2020 to United Arab Emirates (UAE) was investigated to ensure compliance with the standard specifications and requirements by the regulatory and supervisory authorities, maintain the health and safety of consumers and improve food safety. An accurate, rapid, and reliable method for the simultaneous determination of pesticide multi-residues in 230 samples imported dates by liquid chromatography coupled with tandem mass spectrometry (LC–ESI (+)-MS/MS) operating in multiple reaction monitoring (MRM) mode and modified quick, easy, cheap, effective, rugged, safe (QuEChERS) method was used. The performance of the analytical method was validated in accordance with EU SANCO guidelines (SANTE/12682/2019) for monitoring pesticide multi-residues to check compliance with existing regulations, especially for European Community. Residues level of 343 compounds were determined in 230 samples. Results indicated that the percentage of samples with residues above the maximum residue levels (MRL) was 4.34% in dates samples, whereas samples with residues within MRL were 7.39% in dates samples. A total of 230 samples of 88.26% were free from detectable residues. Out of the 343 pesticides tested, 11 pesticides were found above the limit of detection, according to UAE, Codex, and European regulations. The main purpose of this work is to inform citizens and traders who have concerns about food safety on the capability of the MOCCAE on quality assurance regarding pesticide residue in imported food.
The animal feed materials contaminated with heavy metals, which usually comes from soils to plant, atmosphere and contaminated seawater. Various animal feed and feed supplements imported by local agents at United Arab Emirates (UAE) subjected for analysis using ICP- MS technique the concentration of the four selected heavy metals, namely; Arsenic (As), Lead (Pb), Cadmium (Cd), and mercury (Hg), found to be within the national standard.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
