Parents kept food diaries for 3 days before urine collection, and they distinguished organic and conventional foods based on label information. Children were then classified as having consumed either organic or conventional diets based on analysis of the diary data. Residential pesticide use was also recorded for each home. We collected 24-hr urine samples from 18 children with organic diets and 21 children with conventional diets and analyzed them for five OP pesticide metabolites. We found significantly higher median concentrations of total dimethyl alkylphosphate metabolites than total diethyl alkylphosphate metabolites (0.06 and 0.02 mumol\/L, respectively; p = 0.0001). The median total dimethyl metabolite concentration was approximately six times higher for children with conventional diets than for children with organic diets (0-17 and 0.03 mumol\/L; p = 0.0003); mean concentrations differed by a factor of nine (0-34 and 0.04 mumol\/L). We calculated dose estimates from urinary dimethyl metabolites and from agricultural pesticide use data, assuming that all exposure came from a single pesticide. The dose estimates suggest that consumption of organic fruits, vegetables, and juice can reduce children&rsquo;s exposure levels from above to below the U.S. Environmental Protection Agency&rsquo;s current guidelines, thereby shifting exposures from a range of uncertain risk to a range of negligible risk. Consumption of organic produce appears to provide a relatively simple way for parents to reduce their children&rsquo;s exposure to OP pesticides.\u00a0\u00bb<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-54473","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"CURL CL,UNIV WASHINGTON,SCH PUBL HLTH & COMMUNITY MED PNASH CTR DEPT ENVIRONM HLTH;DEH BOX 357234,HLTH SCI BLDG,F-233,1959 NE PACIFI; SEATTLE WA 98195, USA. ccurl@u.washington.edu \"","annee":"2003","mois":"3","numero":"111:3","page":"377-382","auteurs":[{"ID":54471,"post_author":"0","post_date":"2018-12-04 06:44:35","post_date_gmt":"2018-12-04 05:44:35","post_content":"","post_title":"Cynthia L Curl","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"cynthia-l-curl","to_ping":"","pinged":"","post_modified":"2018-12-04 06:44:35","post_modified_gmt":"2018-12-04 05:44:35","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/cynthia-l-curl\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":53164,"post_author":"0","post_date":"2018-12-04 06:14:50","post_date_gmt":"2018-12-04 05:14:50","post_content":"","post_title":"Fenske","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"fenske","to_ping":"","pinged":"","post_modified":"2018-12-04 06:14:50","post_modified_gmt":"2018-12-04 05:14:50","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/fenske\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54472,"post_author":"0","post_date":"2018-12-04 06:44:37","post_date_gmt":"2018-12-04 05:44:37","post_content":"","post_title":"Elgethun","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"elgethun","to_ping":"","pinged":"","post_modified":"2018-12-04 06:44:37","post_modified_gmt":"2018-12-04 05:44:37","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/elgethun\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":10448,"post_author":"0","post_date":"2018-12-03 18:23:32","post_date_gmt":"2018-12-03 17:23:32","post_content":"","post_title":"Environmental health perspectives","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"environmental-health-perspectives","to_ping":"","pinged":"","post_modified":"2018-12-03 18:23:32","post_modified_gmt":"2018-12-03 17:23:32","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/environmental-health-perspectives\/","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) -
