The method for monitoring these residues is based on matrix solid-phase dispersion and liquid chromatography with UV or atmospheric pressure chemical ionization\/mass spectrometry (APCI\/MS) detection, Orange samples representing 11 varieties were collected from an agricultural cooperative and examined for the 5 pesticides, In 74.6% of all analyzed samples, the pesticide residues were below detection limits, which ranged from 0.002 to 0.05 mg\/kg, Residues were detected in 25.4% of the samples, with higher incidences of diflubenzuron, flufenuxuron, hexythiazox, and benfuracarb; hexaflumuron residues were detected only occasionally, Two different pesticides exceeded maximum residue limits (MRLs) in 4 (2.7%) of the orange samples, Diflubenzuron surpassed 1 mg\/kg MRL in 3 samples and flufenuxuron exceeded the 0.3 mg\/kg MRL in 3 samples, The estimated daily intake of the 5 pesticide residues during the period was 0.077 &micro;g\/kg body weight per day, This value is much lower than the total admissible daily intake proposed by the Food and Agricultural Organization and the World Health Organization.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-56809","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"VALENZUELA AI,UNIV VALENCIA,TOXICOL LAB FAC FARM;AV VICENT ANDRES ESTELLES S-N; BURJASSOT 46100, SPAIN.","annee":"2001","mois":"5","numero":"84:3","page":"901-909","auteurs":[{"ID":40861,"post_author":"0","post_date":"2018-12-04 02:23:15","post_date_gmt":"2018-12-04 01:23:15","post_content":"","post_title":"Pico","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"pico","to_ping":"","pinged":"","post_modified":"2018-12-04 02:23:15","post_modified_gmt":"2018-12-04 01:23:15","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/pico\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":14556,"post_author":"0","post_date":"2018-12-03 19:11:08","post_date_gmt":"2018-12-03 18:11:08","post_content":"","post_title":"Guillermina Font","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"guillermina-font","to_ping":"","pinged":"","post_modified":"2018-12-03 19:11:08","post_modified_gmt":"2018-12-03 18:11:08","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/guillermina-font\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":56808,"post_author":"0","post_date":"2018-12-04 07:29:14","post_date_gmt":"2018-12-04 06:29:14","post_content":"","post_title":"Valenzuela","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"valenzuela-3","to_ping":"","pinged":"","post_modified":"2018-12-04 07:29:14","post_modified_gmt":"2018-12-04 06:29:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/valenzuela-3\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":5546,"post_author":"0","post_date":"2018-12-03 17:29:02","post_date_gmt":"2018-12-03 16:29:02","post_content":"","post_title":"JOURNAL OF AOAC INTERNATIONAL","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-aoac-international","to_ping":"","pinged":"","post_modified":"2018-12-03 17:29:02","post_modified_gmt":"2018-12-03 16:29:02","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-aoac-international\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
