Isotope dilution standards were spiked before the extraction to account for extraction inefficiency and loss of analytes during sample workup. Recoveries were &gt;90% for all of the compounds in each matrix. The limit of detection (LOD) ranged from 0.03 to 0.3 &mu;g\/kg, whereas the limit of quantitation (LOQ) ranged from 0.1 to 1.0 &mu;g\/kg. All analytes can be monitored in a single GC-MS\/MS run with a run time of 20 min. Occurrence of these endocrine-disrupting chemicals (EDCs) in vegetables and fruits from local markets was observed using the established analytical method. BPA was detected in all vegetable and fruit samples, ranging from 0.2 &plusmn; 0.1 to 9.0 &plusmn; 4.9 &mu;g\/kg, indicating significant exposure potential for humans. NP was detected in pumpkin, sweet potato, citrus, and apple samples. The concentration of 4-n-NP ranged from 5.3 &plusmn; 2.4 to 18.9 &plusmn; 8.0 &mu;g\/kg, whereas that of 4-NP ranged from 5.1 &plusmn; 2.6 to 12.2 &plusmn; 3.6 &mu;g\/kg. Concentrations of 17-&beta;-estradiol in vegetables and fruits ranged from 1.3 &plusmn; 0.4 to 2.2 &plusmn; 1.0 &mu;g\/kg) except those in tomato and strawberry, in which no 17-&beta;-estradiol was detected. The estimated daily intake of 17-&beta;-estradiol was beyond the recommended acceptable daily intake (ADI) for children as recommended by the Joint <span class='tooltipsall tooltip_post_id_79592 classtoolTips79592'>FAO<\/span>\/WHO Expert Committee on Food Additives (JECFA).<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-35250","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Indian River Research and Education Center, University of Florida\/IFAS, Fort Pierce, Florida 34945-3138, United States.","annee":"2013","mois":"1","numero":"61:1","page":"84-89","auteurs":[{"ID":35247,"post_author":"0","post_date":"2018-12-04 00:41:19","post_date_gmt":"2018-12-03 23:41:19","post_content":"","post_title":"Jianjun Wu","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"jianjun-wu","to_ping":"","pinged":"","post_modified":"2018-12-04 00:41:19","post_modified_gmt":"2018-12-03 23:41:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/jianjun-wu\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":35248,"post_author":"0","post_date":"2018-12-04 00:41:20","post_date_gmt":"2018-12-03 23:41:20","post_content":"","post_title":"Stoffella","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"stoffella","to_ping":"","pinged":"","post_modified":"2018-12-04 00:41:20","post_modified_gmt":"2018-12-03 23:41:20","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/stoffella\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":34593,"post_author":"0","post_date":"2018-12-04 00:32:02","post_date_gmt":"2018-12-03 23:32:02","post_content":"","post_title":"Blumenthal","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"blumenthal","to_ping":"","pinged":"","post_modified":"2018-12-04 00:32:02","post_modified_gmt":"2018-12-03 23:32:02","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/blumenthal\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":35249,"post_author":"0","post_date":"2018-12-04 00:41:21","post_date_gmt":"2018-12-03 23:41:21","post_content":"","post_title":"Wilson","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"wilson","to_ping":"","pinged":"","post_modified":"2018-12-04 00:41:21","post_modified_gmt":"2018-12-03 23:41:21","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/wilson\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":34177,"post_author":"0","post_date":"2018-12-04 00:24:14","post_date_gmt":"2018-12-03 23:24:14","post_content":"","post_title":"J AGRIC FOOD CHEM","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"j-agric-food-chem-2","to_ping":"","pinged":"","post_modified":"2018-12-04 00:24:14","post_modified_gmt":"2018-12-03 23:24:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/j-agric-food-chem-2\/","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) -
